Weather of 2005

The following is a list of weather events that occurred on Earth in the year 2005. The year began with a weak El Niño, although this would fade into a neutral phase later in the year. The most common weather events to have a significant impact are blizzards, cold waves, droughts, heat waves, wildfires, floods, tornadoes, and tropical cyclones.

Types
The following listed different types of special weather conditions worldwide.

Tropical cyclones


When the year began, a tropical low was active near the northwest coast of Australia, which soon became the first named storm of the year – Tropical Cyclone Raymond, which soon moved ashore the Kimberley region. Throughout the year, there were a total of nine named storms in the Australian basin. The strongest and most notable of these was powerful Cyclone Ingrid, which made landfalls in Queensland, Northern Territory, and Western Australia, the only cyclone on record to strike all three regions as a severe tropical cyclone. Two Australian storms entered the South-West Indian Ocean, where an additional six named storms developed. Also in the southern hemisphere, the South Pacific was active with eight named storms, including a succession of four cyclones that struck the Cook Islands – Meena, Nancy, Olaf, and Percy. The four cyclones' monetary damage totaled over US$25 million, equivalent to 14% of the country's gross domestic product (GDP).

The two deadliest tropical cyclones of the year were a part of the record-breaking 2005 Atlantic hurricane season. In October, Hurricane Stan and a broader weather system produced severe flooding across eastern Mexico and Central America, killing 1,668 people, with Guatemala hit the hardest. In late August, Hurricane Katrina became the costliest U.S. hurricane, leaving $125 billion in damage and 1,392 deaths. The strongest tropical cyclone of the year was Hurricane Wilma, which in October became the most intense Atlantic hurricane ever recorded, with a barometric pressure of 882 mbar. Wilma was one of four Category 5 hurricanes – the strongest ranking on the Saffir-Simpson scale – in the hyperactive season, along with Emily, Katrina, and Rita. The 2005 Atlantic hurricane season was the most active season on record, with 28 named storms in the Atlantic, including an unnamed subtropical storm, as well as Zeta, which developed in December and continued into early January 2006.

Also in the northern hemisphere, there were 23 named storms in the western Pacific Ocean, including 13 typhoons, of which Haitang was the strongest. In the eastern Pacific, there were 15 named storms, of which Kenneth was the strongest and longest-lived. In the North Indian Ocean, there were four named storms, although none of them intensified beyond a cyclonic storm, or roughly a weak tropical storm.
