The final storm was a Major hurricane Iota which has become the first and also the only Category 5 storm of the Atlantic hurricane season 2020. Last year has reached an unpreceded 30 named storms, an absolute record-breaking number of storms in one season. Those were Hanna, Isaias, Laura, Sally, Delta, and Zeta. The 2020 storms have used all the designated tropical cyclone names and dug deep into the Greek Alphabet storm names.Īnd to top those numbers, a record-breaking 11 storms made landfall in the United States, including 6 hurricanes. It was almost too hard to keep track of all the activity. If we remember the 2020 Atlantic hurricane season, it was setting record after record with so many storms forming. 2020 ATLANTIC HURRICANE SEASON WAS EXCEPTIONAL, COULD IT REPEAT THIS YEAR? ![]() Let’s just remember a devastating hurricane Laura in Louisiana, or Eta and Iota in central America, or also a destructive hurricane Michael in 2018. ![]() Not after such a devastating and record-breaking Atlantic hurricane season in recent years. Such forecast is surely not something the residents of the US Gulf Coast and the Caribbean region want to hear. Something to consider and be hurricane aware of as we enter the new Atlantic hurricane season in less than a month and a half from now. A typical season has about fifty-fifty probability of the US mainland getting hit. The very concerning part of the forecast for the upcoming hurricane season is the high chance (almost 70 percent) of a major hurricane landfall along the United States coastline, and nearly 60 percent for the Caribbean. And La Nina (negative ENSO phase) helps those to maintain and develop. Normally, hurricanes like low-shear environments with a lot of warm/hot sea waters which bring plenty of very moist air mass. This hints that upcoming tropical cyclone formation will easily fuel from the very warm ocean waters.įor a hurricane to organize and gain strength, the weather conditions have to be just right. Notice also that the temperatures in the region known as MDR (main development region – between Africa and the Caribbean Sea) are warmer than average. It is an obvious sign that most of the Atlantic, the Caribbean, and the Gulf is quite warmer than normal. Although the tropical Pacific Ocean waters are gradually warming up now, weak La Nina is expected to continue until early summer this year, with ENSO conditions revert to neutral a month or two later.Īttached below is the video animation of the Atlantic sea temperature anomaly over the last couple of months. Thanks to the ongoing La Nina global weather pattern and well-above-average Atlantic sea temperatures, including the Caribbean and the Gulf temperatures, the upcoming hurricane season is expected to be rough. The short-term average (taken over the last 15 years – between 19) is 14 named storms. The long-term average (taken over the last 70 years – between 19) of named storms is 11. The Atlantic basin covers the area which includes the entire Atlantic Ocean, the Gulf of Mexico, and the Caribbean Sea. The official Atlantic hurricane season runs from June 1st through November 30th. The image below is the infrared satellite view of a Category 5 hurricane Iota in mid-November last year. Note: an average hurricane season normally produces 14 named storms, 7 hurricanes, and 3 major hurricanes. For 2021, the CSU team calls for 17 named tropical cyclone formations, including 8 hurricanes and also the striking 4 major hurricanes. One of the most recognized and trusted hurricane season early predictions is made by the Colorado State University (CSU) team of scientists, led by Dr. Just in: Enrique becomes the first hurricane of the Eastern Pacific season 2021, heads for the Baja California peninsula while threatening Mexico with dangerous flooding After such an active and devastating record number of named storms and destructive hurricanes, this year is expected to bring much above normal activity again. The upcoming 2021 Atlantic hurricane season is once again anticipating an active year. ![]() With a quite concerning notice that also an above-average probability of hurricane landfalls along the US coastline and in the Caribbean is likely. First predictions have been released, and the message is straightforward: Yet another very active hurricane season is expected in 2021. After the record-breaking Atlantic hurricane season last year, it appears likely that 2021 is in for the sixth consecutive above-average year.
