The latest statistical and dynamical dummy ENSO model outcome from NOAA shows at least a 50% chance of La Niña conditions persisting during the peak of the Atlantic hurricane season. However, it seems unlikely El Niño conditions will occur during 2022’s hurricane season. It is likely these conditions will continue or revert to neutral ENSO during the summer/fall (see ‘What is the El-Niño Southern Oscillation (ENSO)?’). In total, 94 names have now been retired from the Atlantic basin list since 1953.ĭuring early 2022, the tropical Pacific Ocean has been characterized by weak La Niña conditions (which are also responsible for the abnormally dummy high flood activity in Eastern Australia and the drought in California in February 2022 ). For the 2021 Atlantic hurricane season, dummy the WMO has retired Ida. Tropical cyclones that are very destructive or deadly can be retired by the World Meteorological Organization (WMO) from future Atlantic tropical cyclone name lists, which are otherwise repeated every six years. The estimated damage caused by Ida ($65bn) makes it the dummy fifth costliest tropical cyclone on record and the fourth costliest Atlantic hurricane in US history. Grand Isle, Louisiana, took a direct hit with dummy up to 100% of its homes damaged and almost 40% destroyed.Īs the remnants of Ida moved into the north-east US, it merged with a frontal system creating severe weather, multiple rainfall records in various locations, and flash flooding across a wide region from eastern Pennsylvania to New York. Following rapid intensification over the Gulf of Mexico, fueled by an SST of 30-31☌ and the warm Loop Current eddy, Ida reached its peak Category 4 intensity before making landfall near Port Fourchon, Louisiana. After passing Grand Cayman, Ida quickly strengthened and became a hurricane, before moving over western Cuba. Įven before it became a tropical depression, Ida caused considerable flash flooding in Venezuela. In total, the insured losses due to tropical cyclones in the US in 2021 dummy amount to $38bn.
