Tropical cyclones in 2024

In 2024, tropical cyclones will form in seven major bodies of water, commonly known as tropical cyclone basins. Tropical cyclones will be named by various weather agencies when they attain maximum sustained winds of 35 knots. So far, thirty-four systems have formed, with twenty-four of them being named. The most intense storm of the year so far is Djoungou, with a minimum barometric pressure of 922 hPa. Among this year's systems, so far, six have intensified into major tropical cyclones. One system, that being Hurricane Beryl, intensified into a Category 5 tropical cyclone on the Saffir–Simpson scale (SSHWS) with one-minute sustained winds of 145 kn. The ACE index for 2024 (seven basins combined) so far, as calculated by Colorado State University (CSU), is approximately 170.545 units. This number represents sum of the squares of the maximum sustained wind speed (knots) for all named storms while they are at least tropical storm equivalent intensity, divided by 10,000.

Tropical cyclones are primarily monitored by ten warning centers around the world, which are designated as a Regional Specialized Meteorological Center (RSMC) or a Tropical Cyclone Warning Center (TCWC) by the World Meteorological Organization (WMO). These centers are: National Hurricane Center (NHC), Central Pacific Hurricane Center (CPHC), Japan Meteorological Agency (JMA), Indian Meteorological Department (IMD), Météo-France (MFR), Indonesia's Meteorology, Climatology, and Geophysical Agency (BMKG), Australian Bureau of Meteorology (BoM), Papua New Guinea's National Weather Service (PNGNWS), Fiji Meteorological Service (FMS), and New Zealand's MetService. Unofficial, but still notable, warning centers include the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA; albeit official within the Philippines), the United States's Joint Typhoon Warning Center (JTWC), and the Brazilian Navy Hydrographic Center.

Global atmospheric and hydrological conditions
After the New Year, the MJO's amplitude weakened, with its eastward propagation slowing down due to the positive phase of the Indian Ocean Dipole (IOD) and an equatorial Rossby wave. Despite that, the MJO briefly caused El Niño-like wind anomalies to become easterly at the Date Line. There was also a significant increase in convection across the eastern Indian Ocean in January as the Dipole began weakening. However, in the middle of January, the MJO began steadily intensifying, enhancing convection across the Maritime Continent. Despite that, intra-seasonal activity persevered, although the MJO produced convection in the Western Pacific. In Australia, the monsoonal trough's arrival was delayed until January 10, possibly due to the El Niño event. On April 16, the dominant El Niño event ended.

North Atlantic Ocean
Though the 2024 Atlantic hurricane season officially began on June 1, it got off to the slowest start since 2014. This was due to a large stationary heat dome over Central America and Mexico, as tropical cyclogenesis in June often occurs over the Gulf of Mexico and northern Caribbean Sea. The season's first named storm, Tropical Storm Alberto, formed in the western Gulf of Mexico on June 19, then proceeded to make landfall on the northeastern coast of Mexico the following day. On June 28, Tropical Storm Beryl formed at 43.6° W, being the second-easternmost cyclone on record in the tropical Atlantic, behind only Tropical Storm Bret in 2023. The next day, Beryl intensified into a hurricane at 49.3° W, becoming the easternmost June hurricane in the tropical Atlantic on record, ahead of the 1933 Trinidad hurricane. Reaching 53.9 °W, Beryl became the easternmost June major hurricane in the tropical Atlantic, and the first June major hurricane since Alma in 1966. Beryl also became the earliest Category 4 Atlantic hurricane on record, ahead of 2005's Hurricane Dennis. On June 30, Tropical Depression Three formed in the Bay of Campeche, becoming Tropical Storm Chris only six hours later. Chris quickly moved ashore in Mexico the following morning. Hurricane Beryl became a Category 5 that same morning, becoming the earliest Category 5 hurricane on record in the Atlantic, and beating out Hurricane Emily of 2005.

Eastern & Central Pacific Oceans
On June 29, the National Hurricane Center (NHC) noted that a low-pressure area could form off the coast of Mexico. On July 2, a broad area of low pressure formed south of the coast of Mexico. Showers and thunderstorms within the disturbance became better organized beginning late the following day, and Tropical Depression 01E formed during the morning of July 4. Slightly intensifying, the compact system became Tropical Storm Aletta a few hours later.

Western Pacific Ocean
The Pacific typhoon season began abnormally late, with no systems forming for five months until May 22, when a tropical storm named Ewiniar formed southeast of Palau, marking it as the fifth-latest start of a Pacific typhoon season since reliable records began. Ewiniar went straight to the Philippines to make nine landfalls in Homonhon Island; Giporlos, Eastern Samar; Basiao Island; Cagduyong Island; Batuan, Masbate; Masbate City; Torrijos, Marinduque; Lucena, Quezon and Patnanungan. It began to move over the warm tropical waters of Lamon Bay, where the JTWC and the JMA upgraded Ewiniar into a minimal typhoon. Ewiniar began to deteriorate as it moved away from land due to its topographical effects from the island. On May 30, another tropical depression formed southeast of Haikou, China. The next day, at 03:00 UTC, JTWC designated the disturbance as Tropical Depression 02W. A few hours later, JMA assigned the name Maliksi as they upgraded 02W into a tropical storm. Shortly after being named, on May 31, Maliksi made landfall in Southern China. JMA and JTWC discontinued warnings as Maliksi moved inland and dissipated on June 2.

After many weeks of inactivity, on July 13, a tropical depression formed east of Vietnam. Shortly after, it tracked into Vietnam, dissipating soon after. On July 19, two tropical disturbances were recognized by the JTWC: one southeast of Manila while the second is east of Palau. Soon after, the two disturbances on either side were upgraded into a depression and named by the PAGASA. The first west of Batangas was named Butchoy while the second east of Virac was named Carina. JTWC followed suit and designated Butchoy as Tropical Depression 04W and Carina as Tropical Depression 05W. At 16:05 JST (00:05 UTC) of the next day, 05W was given the name Gaemi by the JMA.

North Indian Ocean
After months of inactivity, on 21 May, a low-pressure area started to develop due to an Upper-air circulation over the Bay of Bengal. The LPA got strengthened by favorable conditions like Rossby waves, Madden–Julian oscillation and the beginning of the Monsoonal flow in the Indian Ocean. Hence, IMD (India Meteorological Department) began monitoring the cyclonic circulation. Later that day, Joint Typhoon Warning Center (JTWC) also started tracking the system, noting that the system could become a monsoon depression. On 23 May, the IMD upgraded the system to a well-marked low, stating that it was rapidly coalescing. The system then intensified into a depression (BOB 01/Invest 99B) on 24 May. Owing to favorable conditions and high Sea surface temperature over Northern Bay of Bengal, the depression intensified into a cyclone named Remal. On May 26, Remal intensified into a severe cyclonic storm before making landfall at Bangladesh. Remal later moved inland and dissipated on May 28.

On July 19, IMD marked an area of low pressure off the coast of Odisha. The disturbance was later upgraded into a depression, designated as BOB 02. However, the depression moved inland, weakening into a well-marked low-pressure area.

January - June
The first system of the season, Tropical Storm Alvaro, formed on December 30, 2023 and persisted into 2024. Before becoming post-tropical on January 3, it made landfall in Morombe District, Madagascar, killing nineteen people. After a brief lull in activity, Tropical Cyclone Belal formed on January 11. severely affecting Mauritius and Réunion, with the latter suffering the brunt of the storm, causing six deaths in the process. On January 22, Moderate Tropical Storm Candice formed. Eight days later, Intense Tropical Cyclone Anggrek entered the basin, while Tropical Depression 05 formed. Intense Tropical Cyclone Djoungou formed on 13 February and exited the basin less than a week later. Severe Tropical Storm Eleanor formed on 17 February, bringing intense rainfall and winds causing massive damage. Severe Tropical Storm Filipo emerged on 2 March near Mozambique displacing 48,000 people and damaging 8,000 houses. Tropical Depression Neville crossed into the basin on 24 March but MFR discontinued warning issuance. Short-lived Tropical Cyclone Gamane emerged on 25 March, causing a total of 19 deaths, 3 people missing and at least 90,000 affected.

Off-season Tropical Cyclone Hidaya made rare landfall in Tanzania on 30 April. Another off-season, Tropical Cyclone Ialy, formed on 16 May near Comoros and killing a girl and injuring four others, while another person died due to a fallen wall.

January - June
After a brief lull in activity, Tropical Cyclone Anggrek would form northwest of the Cocos Islands on January 10. The next day, Tropical Low 03U would form in the southern Joseph Bonaparte Gulf. The day after that, Tropical Cyclone Kirrily would form. On 30 January, Subtropical Low 06U formed.

January - June
After a significant lull in activity, Tropical Disturbance 04F formed on January 25 and dissipated the next day. On February 1, 06U entered the South Pacific basin and was designated 05F by the FMS. After the system exited to the Australian region and struggled against moderate wind shear, 05F re-entered on February 7 and JTWC designated it tropical storm 12P. On February 3, the FMS designated 06F and was later named Nat on February 5. The FMS upgraded Nat to a Category 2 tropical cyclone the next day before wind shear led to the system's demise. Simultaneously, Tropical Disturbance 07F formed on February 5 before dissipating. 08F quickly developed and the FMS named Osai on February 7 before an increase in wind shear caused the storm to dissipate. On February 11, 09F developed and was short-lived due to high wind shear. On February 14, the FMS designated 10F and soon the JTWC initiated advisories on Tropical Cyclone 15P. However, 10F was short-lived due to increasing wind shear.

South Atlantic Ocean
On February 16, the CHM stated that a subtropical depression had formed in the Rio de Janeiro basin. Two days later, the cyclone acquired tropical characteristics and became a tropical depression. In the early hours of 19 February, the depression developed into a tropical storm, thus receiving the name Akará.

January
January was slightly active featuring eight systems forming with four of them being named. Tropical Storm Alvaro from the South-West Indian Ocean persisted into 2024 and made landfall in Madagascar, killing nineteen and causing some damages. Cyclone Belal affected Reunion and Mauritius, causing six fatalities. In the Australian region, Cyclone Kirrily affected Queensland while Cyclone Anggrek formed in the basin, entered the South-West Indian Ocean on January 25, and became a Category 4-equivalent tropical cyclone on January 28, making it the strongest storm of the month, as well as the first major tropical cyclone of the year.

February
February was above-average, featuring nine systems with six of them being named. In the South Pacific, Cyclones Nat and Osai affected Samoa, with the former peaking as a Category 2 tropical cyclone before dissipating on February 10. In the South-West Indian ocean, Cyclone Djoungou is the strongest system this month. Cyclone Eleanor affected sparsely over the Mascarene Islands. In the South Atlantic, Tropical Storm Akará affected Southern Brazil. In the Australian region, Cyclone Lincoln crossed through the Northern Territory inland just after making landfall in that particular area.

March
March was near-average, featuring seven systems, with four of which have been named. The month began in the South-West Indian Ocean with Tropical Storm Filipo, which recently affected Madagascar and Mozambique as a severe tropical storm. On the other side of the basin, Cyclone Megan made landfall in Borroloola, Australia just after reaching its peak as a Category-3 cyclone, bringing destructive winds and heavy rain in the area. Cyclone Neville, is the strongest tropical cyclone so far in this month. Before the end of the month, Cyclone Gamane made landfall in the northeastern tip of Madagascar as a Category-2 cyclone before it dissipated on March 28.

April
April was an unusually inactive month, featuring four systems, with three getting named. The month started with Cyclone Olga, which formed over the open waters of Western Australia and peaked as a Category 4-equivalent major cyclone as it remains over the Indian Ocean. Shortly after Olga degenerated into a tropical low, short-lived Cyclone Paul would also form in the Coral Sea. 12U formed on April 12 and dissipated 2 days later. On the last day of April, Cyclone Hidaya formed near Seychelles and made a rare landfall in Tanzania as a weakening tropical storm.

May
May was an average month, featuring five cyclones, with four receiving names, the month started with Tropical Storm Ialy, which formed near Comoros and intensified into a compact tropical cyclone. On May 22, Typhoon Ewiniar formed southeast of Palau, traversing the Philippines before strengthening as a potent Category-2 typhoon over Lamon Bay. Cyclone Remal formed in the Bay of Bengal on May 24. In the latter part of May, Tropical Storm Maliksi formed in the South China Sea and made landfall in Guangdong Province as a weak tropical storm.

June
June was abnormally inactive. It was the least active June since reliable records began, with only three named storms, all forming in the North Atlantic basin. This month started very late, with no storms developing until June 19, when Tropical Storm Alberto formed in the Bay of Campeche and made landfall in Ciudad Madero, Tamaulipas as a mild tropical storm. On June 28, Hurricane Beryl formed south of Cabo Verde and rapidly intensified into a major hurricane. It brushed through the Windward Islands as a high-end Category 4 major hurricane. Beryl entered the Caribbean Sea, and strengthened further into a Category 5 major hurricane. Tropical Depression Three formed on June 30 near Veracruz, becoming Tropical Storm Chris soon after. Chris would be short-lived as it made landfall in Tuxpan, Veracruz before it dissipated the next day.

July
So far, five storms formed in July with three being named. The month started off with Tropical Storm Aletta, which formed off the coast of Mexico on July 4. On July 19, two tropical cyclones were formed on either side of the basin. Tropical Storm Gaemi formed east of Palau and is expected to become a typhoon. Meanwhile, Tropical Storm Prapiroon formed southeast of Manila and is expected to hit Hainan.

Global effects
There are a total of seven tropical cyclone basins that tropical cyclones typically form in. this table, data from all these basins are added.
