Weather of 2007

 Global weather activity of 2007 profiles the major worldwide weather events, including blizzards, ice storms, tornadoes, tropical cyclones, and other weather events, from January 1, 2007, to December 31, 2007. Winter storms are events in which the dominant varieties of precipitation are formed during cold temperatures; they include snow or sleet, or a rainstorm where ground temperatures are cold enough to allow ice, including freezing rain, to form. Thehy may be marked by strong wind, thunder, lightning thunderstorms, heavy precipitation, including ice storm, wind transporting some substance through the atmosphere, including dust storms, snowstorms, and hail storms. Other major non winter events such as large dust storms, hurricanes, cyclones, tornados, gales, flooding, and rainstorms are also caused by such phenomena.

Very rarely, these weather events may form in summer, though it would have to be an abnormally cold summer, such as the summer of 1816 in the Northeast United States. In most locations in the Northern Hemisphere, the most powerful winter storms occur in March and, in regions where temperatures are cold enough, as late as April.

January 9–12
A low pressure brought up heavy snow and blizzard conditions across the Canadian Prairies. Snowfall locally reached between 8 and 12 in in parts of Alberta, Saskatchewan and Manitoba. Particularly hard-hit was central Saskatchewan, including the city of Saskatoon. The storm was accompanied by strong gusty winds in excess of 40 mph. Two people were killed during the blizzard when their car was stuck near a First Nations reserve in Saskatchewan. Saskatoon's Diefenbaker Airport as well as schools were closed.

Prior of hitting the Prairies, the system brought another windstorm to western British Columbia, with gusts exceeding 60 mph. Additional trees at Stanley Park in Vancouver were uprooted. It also hindered efforts from workers who were trying to repair the inflatable roof of BC Place Stadium (home to the Canadian Football League's BC Lions), which was damaged by winds from a previous storm a few days earlier. A secondary wave following the main storm dumped over 4 inches of snow (10 cm) in the Victoria, Vancouver, and Seattle areas with heavier snow in the mountains. Over 115,000 homes were without power during the storm in B.C.

The storm would later drop some locally heavy amount of snows in parts of northern Ontario and central Quebec with 8 in reported in Saguenay.

A cold front sharply drop temperatures from west to east with some areas getting their coldest days of the season across the Canadian and U.S. plains. The cold air later reached the eastern half of the continent at the end of the week.

January 12–24
Following a prolonged period of mild weather, a series of winter storms produced several waves of damaging freezing rain across the Midwest of the United States and central Canada from the 12th to the 16th causing the deaths of 85 people as of January 20. Several thousands of customers from Texas to New England lost power, some for several days. Some areas received as much as 4 inches of ice (100 mm).

Oklahoma and Missouri were declared disaster areas as they were the most hard hit states from the storms. Areas from Utah to New Brunswick received heavy amounts of snow from the 13th to the 16th. The storm was followed by an intense period of cold across most of the continent from California to Newfoundland and Labrador.

Additional waves of precipitation have affected the south half of the United States from the 16th to 18th from Texas to North Carolina, while another winter storm, called a weather bomb affected portions of New Brunswick, Quebec and Maine on the 19th and 20th with near blizzard conditions. Portions of eastern Quebec received as much as 32 inches of snow (80 cm) in just over 12 hours

A total of 85 deaths across 12 U.S. states and three Canadian provinces, and caused hundreds of thousands of residents across the U.S. and Canada to lose electric power.

Winter storms contributed to deaths in traffic collisions: 14 in Missouri, 8 in Iowa, 12 in Texas, 2 in Minnesota, 4 in New York, 1 in Maine, 1 in Indiana, 4 in Michigan, 3 in Arkansas, 1 in Quebec, 1 in Ontario, 1 in Nova Scotia, 2 in North Carolina, 2 in Kansas, 4 in Nebraska and 25 in Oklahoma. A crash near Elk City, Oklahoma, killed 7 occupants who were inside a minivan when it collided with a tractor-trailer during the storm.

Another winter storm affected the central and southern Plains from the 19th to the 21st bringing snow and ice for most of the area with accumulations that topped off at about 4 to 10 inches of snow (10–25 cm). It also brought a light wintry mix across the Ohio Valley and the mid-Atlantic states on the 21st with little accumulation. Newfoundland and Labrador was the last region affected by the series of storms on the 23rd and 24th.

January 14
Per was the name of a powerful storm with hurricane winds which hit the west coast of Sweden and Norway on the morning of January 14, 2007. In Sweden six people died from the storm and approx. 300,000 households were left without electricity.

January 15–19
A major European windstorm gave heavy amounts of snow across portions of Scotland. Most areas of western Europe from Great Britain to the Czech Republic have experienced damaging winds. Wind gusts have reached 90 mph in the plain and up to 140 mph in the mountain area. Boat, rail and air traffic have been heavily affected, while several hundreds of flights from London, Berlin, Amsterdam, Vienna, Prague and Paris have been delayed or canceled. U.S. Secretary of State Condoleezza Rice shortened her European trip due to the strong winds. Millions of residents were without power including 1 million in the Czech Republic. As of 9:00 pm GMT on January 21, Kyrill had caused 47 fatalities. They were- 13 in Germany, 11 in United Kingdom, 7 in Ireland, 6 in The Netherlands, 4 in Poland, 3 in the Czech Republic 3, 1 in France, 1in Belgium and 1 in Austria.

Germany had 3 tornadoes on February 22 and more tornadoes were confirmed from Poland.

January 23–27
A snowstorm affected a large area of western and central Europe, including France, Great Britain, Austria and Germany bringing locally heavy snow accumulations and ice which disrupted air and train travel in Berlin, Stuttgart and London. Some areas in the Alps region received as much as 1 meter of snow (40 inches). Three people were killed in Germany due to accidents caused by the storm. Over 5,000 motorists were stranded in a highway in eastern France due to the heavy snow amounts. Scattered power outages were reported with central France being affected the most with nearly 85,000 homes without power.

On the 27th abolut 40,000 people had been affected by flooding in Bolivia and Peru

February 1–2
A winter storm crossed through the southern United States, with a mix of winter weather. Several inches of snow fell across parts of Arkansas, Georgia, the Carolinas and Tennessee with scattered sleet and freezing rain farther south. Anywhere from 1–4 inches of snow fell across Tennessee and Arkansas, with lighter amounts in the Carolinas.

February 1–12
A major lake effect snow event, titled Lake Storm "Locust", occurred across the Great Lakes regions for several days. Areas most affected by the localized heavy burst of snows were just east of Georgian Bay area near Parry Sound, east of Lake Huron near Wiarton, in western Michigan, and in north central New York.

Areas near Oswego and northeast of Syracuse received as much as 141 in of snow during that period. There were unofficial reports that two towns on the Tug Hill Plateau southeast of Lake Ontario received over 10 ft of snow – Redfield, with 141 in and Parish, with 121 in. Local accumulations elsewhere on the plateau were well over 1 m. A state of emergency was declared in Oswego County due to the intense snow. Portions of central Ontario received 1 – of snow over the period while heavy accumulations were also reported in western Michigan just off the shores of Lake Michigan.

On February 1, a snow squall just east of Oshawa, Ontario on the north shore of Lake Ontario caused a 15-vehicle pileup including a tractor trailer which burst into flames. Two people were killed in the event. There were no reported deaths related to the event in New York State. However, 20 were killed in other states due to cold weather. The event was very localized; areas outside the narrow bands received little or no snow.

February 7–9
A winter storm blanketed parts of the United Kingdom including the City of London disrupting travel all across the city including numerous flights cancelled from all airports and several motorists were stranding on area roads. Service on the Underground subway system was also affected with several stations been closed. Many schools were also closed for one or two days. The heavy snowfall started life as a low-pressure system sitting out in the Atlantic Ocean, at the time the UK was under the influence of a cold northerly wind. The low pressure system tracked towards the UK on the evening of February 7 and turned readily to snow as it hit the cold air. The snow turned back to rain across southern and western regions, but much of Wales, the Midlands and the south-east had significant snowfalls on the 8th. The West Midlands in particular was badly hit, with up to 6 in reported over high ground – the most snow to fall in this region for 15 years. In Wales, Sennybridge in Powys, reported 15 in on level snow with drifts of up to 3 ft in places. On the 9th, the low pressure over France tracked further north than forecast, bringing more heavy snow for the Midlands and Wales. This caused additional travel disruption as the roads were not gritted and heavy gridlock formed on many of the roads. The snow began to thaw over the weekend and in turn caused some localised flooding.

February 12–16
A major winter storm affected a large area of eastern North America from Nebraska to the Canadian Maritimes. Numerous areas received snow accumulations of over 6 in with isolated reports as much as 1 m in the Adirondacks and the Vermont mountains. Burlington, Vermont set a 24-hour snowfall record, with 25.3 inches. Twelve to sixteen inches (30 to 41 cm) of snowfall and blizzard conditions in central Illinois cancelled classes at the University of Illinois at Urbana–Champaign for two days, the first time classes had been cancelled since 1979.

Large cities including Cleveland, Hamilton, Syracuse, Rochester, Burlington, Quebec City and Sherbrooke received amounts well in excess of 1 foot of snow (30 cm). The city of Hamilton received local snowsqualls bombarding in from Lake Ontario with a north-east wind which dumped over 2 feet of snow (75 cm) in some parts of the city.

Mixed precipitation fell across the southern Ohio Valley and the Interstate 95 corridor from Virginia to Boston, including New York City, Washington, D.C., and Philadelphia.

The storm has been blamed for 35 deaths across 13 states and three Canadian provinces.

February 19–24
A blizzard event took place across eastern Canada on the island of Newfoundland, dumping over 16 in of snow in St. John's, the capital of Newfoundland and Labrador, shutting down most of the city, and closing all area schools. Heavy amounts were reported in the western Avalon Peninsula of the province. The storm previously affected portions of Nova Scotia and dumped locally heavy amounts of snow due to sea effects coming from the Atlantic Ocean and the Bay of Fundy. A new storm on the 23rd and 24th dumped an additional 6 inin the capital with freezing rain, while heavier amount fell just to the west.

February 21–26
A storm moved onto the northern California coast early on the 21st, leading to 1 – of snow across the southern Cascades, Siskiyous, Sierra Nevada, and the mountains of southern California. It also gave moderate snowfall accumulations across the Canadian Prairies between 4 and 8 in across Manitoba. The storm then moved east, bringing up to 2 ft to the mountains of Utah and Colorado. Late on the 23rd, it moved onto the central High Plains and organized into a major storm that spread snow from eastern Colorado northeast into the Upper Midwest and Great Lakes region, and ice from Iowa to northern Indiana. The system then split into two with the northern branch dissipating due to a blocking ridge of high pressure which prevented the blizzard from moving north into Canada. The storm continued into the Mid-Atlantic on the 25th, dropping snow as far south as the Washington, D.C. area.

Snowfall amounts from 12 to 24 in were common in Minnesota, Iowa, Wisconsin, and Illinois, while lighter amounts were reported in Michigan and Ontario. Winona, Minnesota recorded the highest official snowfall total in this region, with 29.5 in as well as La Crosse, Wisconsin with 21 in. Up to 1.5 in of ice accumulation was reported from Iowa eastward into northern Indiana. Sustained winds of 30 – resulted in severe blowing and drifting in some of these locations. 10 people were killed in traffic accidents during the storm including 8 in Wisconsin, one in Ontario and one in Kansas. A forty car pileup resulted in the closing of Interstate 70 between Denver and Goodland, Kansas. This storm caused massive delays and cancellations at Chicago O'Hare and Midway Airport. At one point, 250,000 customers in Iowa were without power. Some people got their power back quickly, for others it took quite a while. The storm then moved into the mid-Atlantic states, where up to 8 inches accumulated. Blizzard or winter storm warnings were in effect at one point in Kansas, Nebraska, South Dakota, Iowa, Minnesota, Wisconsin, Illinois, Indiana, Michigan, Ohio, Pennsylvania, Maryland, Virginia, West Virginia and Washington, D.C.

The storm also brought severe thunderstorms and tornadoes from Kansas to Alabama, hitting Arkansas especially hard, where Dumas was heavily damaged by a tornado.

February 22–23
A snowstorm moved across Scandinavia in northern Europe dumping heavy amounts of snow. The storm was blamed for one fatality in Denmark, while hundreds of flights from Copenhagen and Sweden were cancelled. Numerous motorists were stranded due to drifts that reached locally 3-meters high. A sports hall in Thisted, Denmark also collapsed but the building was vacant.

The 2007 Mozambican flood began in late December 2006 when the Cahora Bassa Dam overflowed from heavy rains on Southern Africa. It worsened in February 2007 when the Zambezi River broke its banks, flooding the surrounding areas in Mozambique. The Chire and Rivubue rivers have also flooded. Avbout 80,600 were evacuated. There were 29 known and 10 unconfirmed deaths in Mozambique.

February 27 – March 2
Another major storm moved into the Pacific Northwest coast on the 27th, adding to the several feet of snow already recorded in the Cascades and Sierra Nevada in the previous few days. It impacted the Upper Midwest, the northern Plains, the Great Lakes and Quebec regions with heavy snow, sleet, freezing rain and high winds by March 1 and 2, in addition to bringing more severe thunderstorms to the South. Already, numerous tornadoes were reported in Alabama, Georgia, Missouri and Kansas including six killers. A deadly tornado struck Enterprise High School, killing 8 students on March 1. On March 2, over 2 inches of rain fell in New York City and snow, sleet and freezing rain fell in the interior Northeast.

Omaha, Nebraska was under a blizzard warning for the first time in 9 years, with much of the city receiving a foot (30.5 cm) or more of snow, and thunder snow as reported at the beginning of the storm. Wind speeds in Omaha were clocked as high as 58 miles per hour, creating snow drifts in outlying areas up to 8 feet depth. The entire state of Iowa was placed under a State of Emergency by Governor Chet Culver while large stretches of Interstate 80 were shut down. The National Guard came into the area to bring generators to restore power until utility lines were repaired.

Several areas in Manitoba as well as the Northern Plains received over 8 in of snow with portions of Wisconsin receiving 16 in, 17 in for parts of Iowa, 12 – in parts of Minnesota with the highest accumulations falling in the northwest suburbs of the twin cities metropolitan region, (Anoka, Champlin, Maple Grove, Plymouth, Rogers)., and up to 21 in across the Dakotas. Portions of Ontario and Quebec from Sault Ste. Marie to Montreal (including Sudbury, North Bay and Ottawa) received between 6 and 10 inches of snow (15–25 cm) on March 2. 80,000 customers lost power in the province with localized heavy amount across the Appalachians. Although Toronto did not receive large amounts of snow around 10 cm, hours of freezing rain that followed created a hazardoussituation the next day when the temperature rose in the city core and under the CN Tower causing massive chunks of ice sheets to cascade off the buildings hundreds of metres below, breaking some vehicle windows in a hotel parking lot. It forced City police to close the Gardiner Expressway on March 5.

The storm with the tornadoes and snow was blamed for 39 deaths including 10 in Alabama, 1 in Missouri, 9 in Georgia, two in Manitoba, two in Ontario, one in Minnesota, three in Michigan, one in Nebraska, four in North Dakota, one in Massachusetts and four in Wisconsin.

March 3–4
Portions of northern China and Mongolia were hit by the worst winter storm in over 50 years. The provinces of Liaoning and Shenyang had adopted emergency measures in able to cope with the storm which shut down numerous highways and canceled numerous flights while disrupting train service. Strong winds created snow drifts of up to 2 meters deep.

Rescue ships had to assist a large group of fisherman on the Yellow Sea following a storm tide. Two people were killed in Tianjin when a storm surge collapsed several warehouses. As much as 50 cm fell in the province in Heilongjiang.

March 14–15
Jordan's second winter storm of the season shut down most roads, schools and businesses across much of the country due to accumulations exceeding 4 in including the capital of Amman.

Much of the Middle East usually have little or no snow during the winters due to much warmer conditions caused by the moderate sea effects from the Mediterranean Sea. However 3 ft of snow fell in a storm 2004, which was the worst since 1950.

The north eastern US snow event
A heavy nor'easter caused severe Precipitation that started as rain across the region during the evening of the 15th, but as colder air moved in aloft, precipitation changed quickly to snow in The Poconos around Midnight EDT on the 16th and in Berks County and the Lehigh Valley around 7 am EDT. Farther to the south, the surge of cold air was confined to a more shallower layer and precipitation changed to sleet around the Greater Philadelphia Metropolitan Area between 6 am and 9 am EDT. Precipitation continued as mainly sleet across the greater Philadelphia through the evening. The nor'easter caused heavy sleet to fall across the greater Philadelphia metropolitan area, heavy snow and sleet also fell across Berks County, the Lehigh Valley and heavy snow hit the Poconos on both the 16th into the early morning of the 17th.

The winter storm caused scores of accidents. Various vehicles rolled over, slid off roads, slid into each other, slammed into guardrails and fishtailed. The afternoon and evening commute slowed to a crawl. In the Greater Philadelphia Metropolitan Area, about 265 schools dismissed early and more than 60 community events were either cancelled or postponed on the 17th. A few schools also closed on the 16th, but most of the others had early dismissals and many after school activities were postponed. Some state offices and county courts also closed early and several municipalities declared snow emergencies over the March 16 to 18.

The winter storm wreaked havoc at Philadelphia International Airport had most flights on the 16th cancelled and it took a couple of days for flights to return to normal. The largest impact of the winter storm within Philadelphia was the cancellation of most of the 1,200 scheduled flights at the Philadelphia International Airport. About 1,000 people were stranded at the airport the night of the 16th. Passengers on about 15 U.S. Airways planes sat on the tarmac for over four hours before gates became available to deplane them. Operations resumed on the 17th, but U.S. Airways still had to cancel about one quarter of its flights because the weather prevented crews and planes from arriving in Philadelphia. About 100 travelers slept at the airport on the night of the 18th. Normal operations resumed on the 19th.

The Pennsylvania Interscholastic Athletic Association postponed several state playoff high school basketball games. A couple of Saint Patrick's Day parades scheduled for Saturday the 17th were also postponed on the 16th. The Philadelphia Flyers hockey team was forced to fly out of Atlantic City International Airport on the 17th. The horse racing card at Philadelphia Park was also cancelled for three days.

On the 17th snow accumulations averaged 4 to 6 in in the local Philadelphia area, 5 to 9 in in Berks County and the Lehigh Valley and 12 to 18 in in the Poconos.

In Berks County and the Lehigh Valley, the snow mixed with and changed over to sleet during the later afternoon and the first half of the evening before it went back to all snow. Precipitation ended early in the day on the 17th (before 3 am EDT) as mainly snow in all areas. Elsewhere in Bucks County, portions of the Northeast Extension of the Pennsylvania Turnpike near Quakertown were stalled when two tractor-trailers collided in the southbound lanes at 2 pm EDT. A six-mile back-up occurred. About 1,900 homes and businesses lost power in Newtown after a vehicle struck a pole.

The sleet forced the closure of the eastbound lanes of the Vine Expressway within the city for about half an hour between the Schuylkill Expressway and Interstate 95 for its removal. In Montgomery County, in Montgomery Township, an accident on Pennsylvania State Route 309 and Taylor Road badly injured one person. In Towamencin Township, two accidents resulted in two injuries occurring.

The storm event in Canada
A strong high pressure system moved across nearby parts of Canada and supplied a fresh supply of cold air into the region.

Hundreds of traffic accidents occurred across the northeast and Canada including one involving a vehicle from George W. Bush's motorcade in Washington, D.C..

The metrological cause of the storm
The winter storm was caused by a nor'easter low pressure system that developed on a cold front that moved through the area on the 15th. Prior to that, unseasonably mild air helped push high temperatures as high as the 70s.

Meanwhile, the low pressure system formed over South Carolina and Georgia on the morning of the 16th and moved northeast. At 2 pm EDT on the 16th, it was near Myrtle Beach, South Carolina; at 8 pm EDT that evening, it was just east of Virginia Beach; at 2 am EDT on the 17th, it was about 100 mi east of Atlantic City, New Jersey and was about 100 mi south of Cape Cod, Massachusetts at 8 am EDT on the 17th. As central pressures go, this was not particularly a powerful system; it was only 996 millibars the morning of the 17th. What contributed to the event, was the strong high pressure system (about 1040 millibars the morning of the 16th). It supplied the fresh cold air needed to change the precipitation over to sleet and freezing rain and increased the pressure gradient (and consequently the wind) between itself and the developing nor'easter low pressure system.

Fatalities
The only serious reported traffic fatality from the storm in Eastern Pennsylvania occurred in Bucks County. An 18-year-old girl from Plumstead Township was killed when her vehicle crossed the center line of an icy Durham Road and collided with a dump truck on the 16th.

Ten people were killed by the storm, all in traffic accidents. This includes six in New Jersey, three in Pennsylvania and one in Maryland.

March 26–29
A storm moved onto the coast on March 26, dropping up to 2 feet of snow in the Sierra Nevada. The storm moved across the Intermountain West on the 27th and developed into a major winter storm across the northern and central Rockies and northern High Plains. Many of the western valleys, from the Wasatch Front through the valleys of Wyoming, onto the Plains of Wyoming and Montana, saw about 6–12 inches of snow, with 1–2 feet in the mountains from the 27th through the 29th. Up to 3 feet fell in the Wasatch Range and Bighorn Mountains. The storm was concentrated around south-central Montana and north-central Wyoming, where such cities as Sheridan and Billings and surrounding areas could see 1–2 feet of snow. Throughout the mountains and on the Plains (including Saskatchewan and Manitoba), this snow was accompanied by strong winds, leading to localized near-blizzard to blizzard conditions.

April 2–7


A late season winter storm dumped a large swath of snow from North and South Dakota, eastward through Minnesota, Wisconsin and into Upper Michigan. Up to 9 inches of snow fell near Bismarck, North Dakota, 11 inches in Brainerd, Minnesota, and areas near Hurley, Wisconsin received 18 inches. Parts of Upper and northern Michigan then saw a major Lake Effect event over approximately five days. Painesdale, Michigan received 65 inches of snow and the National Weather Service in Marquette received 47 inches, shattering most previous April snowfall records for that city. Lake effect also affected the Lake Erie region, cancelling the series between the Cleveland Indians and Seattle Mariners baseball teams in Cleveland, and prompting a move of the next series with the Los Angeles Angels of Anaheim from Jacobs Field to Miller Park in Milwaukee.

In northern New England, the storm hit on Wednesday afternoon and left behind up to a foot and a half of snow, sleet, and freezing rain. Over 180,000 homes lost power, mostly due to broken tree limbs snapping wires. The storm has caused at least one death.

Heavy snow also fell across much of southern and central Quebec, with amounts in excess of 12 in across some areas, with higher amounts over higher terrain in the Charlevoix region. Numerous accidents were reported across the provinces including one involving a firetruck. Two people were killed in accidents across the province.

On the back side of the storm, persistent heavy flurries gave additional accumulations of a few inches across most of Ontario and Quebec.

April 8
Another winter storm affected portions of New Brunswick, Nova Scotia, Quebec and Prince Edward Island on Easter Sunday dumping as much as 12 in of snow locally along with strong winds which caused flight cancellations at Halifax International Airport and scattered power outages, mainly in Nova Scotia.

The storm did shut down some school across Nova Scotia on the 13th.

April 13–16
A major nor'easter struck the eastern half of North America bringing heavy rains, floods, storm surges and damaging wind across coastal areas. New York City itself received nearly 8 in of rain in one day, making it one of the rainiest days ever for the city. Flooding did occur across many suburbs of the region as well as in other areas of the East Coast from Maine to Virginia. In Cape Elizabeth, Maine, an 80 mph wind gust was recorded, along with 30-foot waves that battered the coast. In New York, the National Guard assisted the emergency procedures while Maine, West Virginia and New Jersey declared state of emergencies. Several tornadoes struck the Carolinas killing at least 1 in South Carolina. Additional tornadoes struck northern Texas on the 13th. Also Wildfires were reported in Georgia and Florida, caused by strong winds from Nor'easter.

In addition, heavy snow fell across portions of Colorado, Kansas, New Mexico and Oklahoma on the 13th, bringing about 12 to 18 in across the higher elevations. Then it dumped heavy snow across the Appalachian Mountains and the Laurentians of Quebec on the 15th and 16th. 17 in fell over portions of Vermont, as much as 26 in in Tupper Lake, New York, as much as 40 in in the Charlevoix region of Quebec while 4 to 6.5 (10–16 cm) inches also blanketed the cities of Montreal and Ottawa and the surrounding regions in just a few hours.

In Quebec as much as 160 000 Hydro-Québec customers lost power from the Outaouais to the Quebec City region while several schools were closed north of Montreal. An additional 17 000 households serviced by Hydro One and Hydro Ottawa suffered power outages in Eastern Ontario In the U.S. over 300,000 customers lost power from Maryland to Maine including 55 000 in New York, 50 000 in Pennsylvania, 43 000 in Connecticut, 46 000 in New Hampshire, 17 000 in Maine, 30 000 in Maryland, 25 000 in Vermont and 12 000 in Massachusetts.

Areas west of Denver received a much as 26 inches of snow (near Evergreen) with several other reports of 12 inches or more. while severe weather affected eastern portions of the state.

May 4–5
While much of the Central Plains received heavy rain and damaging tornadoes, regions in higher elevations across the Rockies, including Colorado, Wyoming, Utah, Nebraska and Idaho, received snow, locally a major winter storm. Portions of central and northern Colorado received as much as 12 in of snow during the overnight event.

May 9
Also on May 9, a strong tornado struck Bebejia, Chad destroying the town and killing 14 people.

A European windstorm crosses over Scotland and plunges into the mouth of the North Sea, to the west of Norway, where its strong winds push large bodies of water Southeast, towards coastal regions in England and the Netherlands. The tidal surge puts both nations on red alert as the English evacuate some coastal villages and close the Thames Barrier. The Dutch close the Eastern Scheldt storm surge barrier and the enormous Maeslant barrier in order to prevent massive flooding as the storm mimics the situation that caused the devastating North Sea flood of 1953.
