2020 cyclone season

August was the second most active month of the year, seeing 18 tropical cyclones forming and 15 named storms. [4] By 09:00 UTC on May 17, Amphan had intensified into a very severe cyclonic storm. In addition, it was the fifth consecutive above average Atlantic hurricane season from 2016 onward. [50] The JTWC then issued a Tropical Cyclone Formation Alert on the system, that same day. Other notable warning centres include the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the United States's Joint Typhoon Warning Center (JTWC), and the Brazilian Navy Hydrographic Center. After 2 days, BOB 03 formed, impacting and affecting West Bengal, Bangladesh and the Northeast India. The month started off with the Atlantic's third Greek-named storm, Gamma, and continued with consistent record-breaking Atlantic activity including 4 additional hurricanes; Delta, Epsilon, Zeta and Eta. Near the end of the month, Gonzalo, Hanna and Isaias marked the earliest seventh, eighth, and ninth-named storms on record in the Atlantic, beating the record set by Gert, Harvey and Irene all in 2005 respectively. It gradually intensified into a Severe Cyclonic Storm, reaching its peak intensity. The final typhoon of the season was Typhoon Vamco, which was another serious Philippine typhoon. At the same time, Claudia, another tropical cyclone, formed. In early April, Harold also entered the basin from the Australian region.

The month of May was marginally active with eight tropical cyclones developing and six of those being named. The first and second tropical cyclones of the season in the South Pacific formed within 24 hours of one another earlier this week; now Severe Tropical Cyclone Yasa is headed for Fiji. In late February, 2 new tropical lows formed, and were named Esther and Ferdinand. 6The wind speeds for this tropical cyclone are based on Météo-France which uses wind gusts. [nb 1] Typhoons Bavi, Maysak, and Haishen were a series of three major typhoons to strike the Korean Peninsula in just a two-week span in August and September. [26], The system delayed the withdrawal of the southwest monsoon season by almost a week, a delay compounded by the formation of Depression ARB 03 and Depression BOB 03. [49] Early on November 24, it intensified into a cyclonic storm and it was named Nivar. The Supreme Committee asked people to remain at home in non-emergency circumstances. 57%. The month of July was active, with 14 tropical cyclones forming and 9 being named.

The season concluded on November 19 with the dissipation of Tropical Storm Polo, which briefly existed for around 2 days prior. During most of the year, sea surface temperatures were moderately below normal near the equator, and were highest around 160° E from August to October. [59] However, Burevi slowed down quickly as it became stuck in a col between two subtropical ridges on December 4; thus it stalled just west of Sri Lanka while it weakened back down to the equivalent of a tropical depression due to increasing vertical wind shear. Another depression formed in the West Pacific in the middle of the month and eventually strengthened into Tropical Storm Krovanh over the South China Sea. In mid March, Gretel entered the basin. It's remnants formed ARB 03. It intensified into a depression on the early hours of November 23, as the JTWC also cited that the disturbance intensified into a tropical storm, designating it as Tropical Cyclone 04B.

In the Eastern Pacific two tropical storms, Odalys and Polo, formed but intensified little. It persisted for two weeks and reached category 3 on the Australian tropical cyclone scale before dissipating west of Australia. On January 24, a depression formed and dissipated the next day without been named. Following after Higos, a series of typhoons named Bavi, Maysak, and Haishen formed, all impacting South Korea and Haishen becoming the strongest of the month as a near-Category 5 equivalent typhoon. So far, the top five most intense storms this year are Yasa, Goni, Iota, Harold, Amphan; all of those have attained Category 5 status including Category 4 Haishen, according to the Saffir-Simpson Hurricane Wind Scale, as well as an intensity of no more than 920 mb (27.17 inHg). A total of ten storms developed, with six of these systems were named and had gale-force winds, while two of these named storms developed hurricane-force winds and were classified as severe tropical cyclones. Arthur also developed in the month, giving the North Atlantic season six consecutive seasons with pre-season activity. Gati later became a Category 3 tropical cyclone on the Saffir-Simpson Hurricane Wind Scale, and made landfall in the Arabian Peninsula. Once it made landfall in Central America, it caused more than 180 fatalities. For only the third time ever, and the first in a decade, the 2020 Atlantic hurricane season is the most active of the year, beating the typhoon season, which had below-average statistics, especially in the count of super typhoons. [10] Operations at the port of Salalah were interrupted by the tropical depression. On January 9, a group of climate scientists writing for ENSO Blog published their forecast for atmospheric conditions. Hurricane Hanna and Isaias together would become the first and second hurricanes of the Atlantic hurricane season, with Isaias in particular spawning a damaging tornado outbreak in the Eastern United States. It hampered the system intensification due to a brief interaction with Tropical Depression 01F. Its remnants then affected Malta and Libya. This output is the combined view of several climate models, each using very different methodologies. [2][3] That morning, landslide and flooding warnings were hoisted for parts of eastern Sri Lanka and the Indian state of Kerala were given expectations of torrential rainfall in the coming days. [43], Once onshore, land friction-based shear caused convection to quickly become displaced from the storm's center. We know that cyclones can develop at any time throughout the tropical cyclone season, which runs from November to April," he said. Regional Specialized Meteorological Centers. It reached at the maximum 10 minutes sustained wind speed of 55 km/h (35 mph) and minimum pressure of 1000 mb (29.53 inHg). With the boiling pot and Kirra dishing out insane pits for the likes of Nick Vasicek, Chris Zaffis, Brent Dorrington, Dextar … [56] At 15:00 UTC on December 2, Burevi reached its peak intensity with 1-minute sustained winds of around 85 km/h (50 mph) and a barometric pressure of 996 mbar (29.41 inHg). The Tropical Cyclone (TC) activity expected in the 2020/21 Tropical Cyclone Season to affect Tonga is likely to be around average (1 to 2 cyclones on average). Elsewhere, Tropical Storm Amanda was the costliest storm of the season after its El Salvador landfall. In particular, Goni became tied with Meranti and Haiyan as the most intense typhoon recorded in the Eastern Hemisphere on record, and the most intense cyclone recorded to make landfall in history, with sustained one-minute winds of 315 km/h (195 mph) causing historical levels of damage in the Philippines. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. Douglas made an unusually close pass to the Hawaiian Islands, as a Category 1 hurricane but caused little to no damage. As a result, the ENSO Blog issued La Niña watch, stating a 50-55% chance of a strong La Niña. In July, almost no storms formed, marking the quietest July in over 130 years. After, Intense Tropical Cyclone Gabekile formed, becoming the first of three intense cyclones of 2020. The 2020 Atlantic #hurricane season has now produced 178 ACE (Accumulated Cyclone Energy). The IMD issued cyclone warnings early on November 24 on Tamil Nadu, Pondicherry and the country of Sri Lanka as the cyclonic storm accelerates and intensifies. The other half, 2020 began with the arrival of Tropical Depression 01F on November 22, near the Solomon Islands, which would later become Tropical Cyclone Rita. [43] This made Gati the first hurricane-force cyclone to strike the country since reliable records began and by default the nation's strongest. After Nisarga dissipated, there was no activity between June 4 and October 11 - one of the longest gaps in inactivity on record. Throughout 2020, 137 tropical cyclones have formed in bodies of water known as tropical cyclone basins. At the time, the system was at peak intensity with 3-minute sustained winds of 110 km/h (70 mph) and a central pressure of 984 hPa (29.06 inHg). This is NOT what is will be. There are two main seas in the North Indian Ocean – the Arabian Sea to the west of the Indian subcontinent, abbreviated ARB by the India Meteorological Department (IMD); and the Bay of Bengal to the east, abbreviated BOB by the IMD.

TROPICAL CYCLONE POTENTIAL BULLETIN ISSUED BY METEOROLOGICAL SERVICE OF NEW ZEALAND AT 2240 UTC 15-Dec-2020 CURRENT STATUS OF CYCLONE ACTIVITY Tropical Cyclone YASA (category 5) was located near 14.7S 173.5E, Amphan, the first tropical cyclone of the 2020 season in the North Indian basin, made landfall on May 20, 2020. Rita would then peak as a Category 3 on the Australian scale. In the Australian region, two tropical lows formed in and both impacted the Pilbara Region of Western Australia, one reaching near Category 1 tropical cyclone strength according to Australian scale. It strengthened into severe tropical cyclone Uesi and affected New Caledonia and New Zealand. It rapidly weakened and dissipated the next day. [9] 2 days of heavy rainfall, accumulating to 260 mm (10 in), caused floods in Salalah. Yasa became the most powerful tropical cyclone of 2020 beating Goni with a minimum barometric pressure of 899 mb (26.55 inHg) and maximum wind speed of 250 km/h (155 mph). Amphan simultaneously dissipated. The exception was the number of tropical storms, featuring 17, which was slightly above average for the basin. The system began bringing torrential rainfall to Sri Lanka and Southern India. The official start to the 2020 Cyclone Season is November 1 st – and going on recent model runs there’s already a small tropical depression forecast to form over Southwest Pacific. "The system — if it develops — will be named Cyclone Esther." The 2020 North Indian Ocean cyclone season is an ongoing event in the annual cycle of tropical cyclone formation. The name Nivar was contributed by Iran. [36], During the overnight of 21 to 22 November the small cyclone quickly organized,[38] with a well-defined eye developing.

Cristobal formed from the remnants of Amanda in May and affected Mexico and the United States, becoming the earliest third named storm in the North Atlantic Ocean on record. Delta and Zeta impacted the Yucátan Peninsula before making landfall in Louisiana. The last depression dissipated in early December. Most destruction was due to Laura, which caused about $16.1 billion (2020 USD) in damage and killed seventy people in Louisiana. The following morning around 10:30 UTC, the IMD upgraded Amphan to a super cyclonic storm with 3-minute sustained winds of 240 km/h (150 mph) and a minimum pressure of 920 hPa (27.46 inHg). 01F became a remnant low and got absorbed by Tropical Depression 02F. Damage and death totals include the damage and deaths caused when that storm was a precursor wave or extratropical low, and all of the damage figures are in 2020 USD. On November 24, Tropical Low 01U formed off the coast of Sumatra which started the 2020–21 season.
