This occurs because those increased upper-level winds can tear apart hurricanes as they try to form. Strong westerly winds spurred on by El Niño – a natural climate pattern marked by warmer-than-average Pacific Ocean water – tend to prevent nascent Atlantic storms from developing. 'Large uncertainty': How bad will the 2023 hurricane season be? Why this year's forecast comes with 'large uncertainty' What role does El Niño play? This forecast covers storms that form in the Atlantic basin, which includes the Caribbean Sea and the Gulf of Mexico.Ĭolorado State meteorologist Phil Klotzbach told USA Today that two of the six predicted hurricanes should develop into major hurricanes – category 3, 4 or 5 – with sustained wind speeds of 111 mph or greater. A tropical storm becomes a hurricane when its sustained winds reach 74 mph.Ī typical year averages about 14 tropical storms, with seven spinning into hurricanes, based on weather records that date from 1991 to 2020.

The last one was Tropical Storm Arlene in the Central Atlantic in 2017. The area already dodged its first scare in early April after forecasters began watching for the potential development of a tropical or subtropical storm, which ultimately fizzled.Īpril tropical systems are rare. coast and in the eastern Atlantic, is unusually warm for spring. But experts have already noted this season comes with a high level of uncertainty based on a developing El Niño and an unusually warm Atlantic Basin.Ī analysis indicates that the Gulf of Mexico, off the Southeast U.S. The 2023 Atlantic hurricane season, predicted to be “slightly below-average,” is rapidly approaching its June 1 kickoff date and will run until Nov.
