The Atlantic hurricane season was off to a quiet begin earlier than a number of storms exploded onto the scene in September, and the identical forces that allowed Ian to quickly intensify may result in extra hurricanes in coming weeks, meteorologists warn.
Ian struck Florida this week after an unusually inactive summer season in which no named tropical storms or hurricanes fashioned within the Atlantic Ocean from July 3 to Aug. 30. The final time that occurred was 1941, in keeping with researchers.
Then in September, “abruptly, issues began popping,” AccuWeather senior meteorologist Bob Smerbeck advised USA TODAY.
Tropical storm Danielle was named on Sept. 1, adopted by Earl, Fiona, Gaston, Hermine and Ian.
Hurricanes Ian and Fiona each grew to become catastrophic Class 4 storms.
And within the subsequent few weeks, “there’s not less than one bonafide likelihood for tropical improvement,” Smerbeck mentioned.

‘EERILY QUIET’:August hasn’t been this devoid of tropical storms since 1997.
A quiet begin to hurricane season
The 2022 hurricane season received off to a sluggish begin, however by August meteorologists warned there may nonetheless be robust storms forward, regardless that none had been named but.
“The primary a part of the season may have been extra energetic than it was,” Nationwide Climate Service Director of Public Affairs Susan Buchanan advised USA TODAY in a press release.
Much less climate programs developed off Africa’s west coast earlier this summer season, and there have been “unfavorable circumstances” for them to show into tropical storms within the western Atlantic, Smerbeck mentioned.
Tropical storm exercise often picks up through the “peak” from late August into October, in keeping with the Climate Service. And we’ve got already seen 9 named storms.
Primarily based on knowledge from 1991-2020, the common Atlantic hurricane season has 14 named storms, with three of them being main hurricanes (Classes 3, 4 or 5 on the Saffir-Simpson Hurricane Wind Scale), in keeping with the Nationwide Hurricane Heart.
The devastation in Florida, the Carolinas and Puerto Rico from main hurricanes Ian and Fiona is greater than sufficient to label the 2022 hurricane season a “unhealthy” one, Buchanan mentioned.
What occurred throughout previous ‘calm’ seasons?
There are not any ensures that this summer season’s quiet hurricane season will return or that the season will proceed to be energetic.
Since 1950, we have had two quiet Augusts with no named storms: 1961 and 1997, in keeping with Phil Klotzbach, a hurricane researcher at Colorado State College.
However 1961 had a particularly busy September, and that ended up a hyperactive season. Whereas 1997 was a robust El Niño 12 months and was a below-average season.
A phenomenon known as wind shear performed a giant position on this hurricane season’s marked uptick beginning in September, Smerbeck mentioned.
To ensure that tropical storms to kind, he defined, they should construct upwards to develop in power, like a tower of bricks. When there’s much less wind shear to knock over the tower, a tropical storm or hurricane is ready to develop stronger and stronger, which is precisely what occurred with Ian, Smerbeck mentioned.
“It’s such as you took the lid off the environment in September,” Smerbeck mentioned.
What do forecasts present for October?
AccuWeather and Nationwide Climate Service meteorologists are monitoring a disturbance within the japanese Atlantic south of the Cabo Verde Islands that would morph right into a tropical storm by late subsequent week.
“There may be now a excessive likelihood {that a} tropical wave south of the Cabo Verde Islands will turn into an organized tropical system,” AccuWeather Senior Meteorologist Dan Pydynowski mentioned.
If wind shear stays low, Smerbeck mentioned, that disturbance may flip right into a tropical storm or worse.
“That one has potential to turn into extra organized,” he mentioned. Meteorologists will know extra in coming days, Smerbeck mentioned.Smerbeck mentioned he’ll be maintaining a tally of the disturbance, as it might be “destined extra to the northwest.”
The subsequent named Atlantic storm might be known as Julia. From there, the names Karl and Lisa are subsequent.
Storms are given names as soon as it has sustained winds of 39 mph. A storm turns into a hurricane when it reaches winds of 74 mph.
