Today marks the end of the 2022 hurricane season, one that Florida will not soon forget.
At a glance, the Atlantic had an average season with 14 named storms, eight hurricanes and two majors. But in fact it was a wild and rocky ride with lots of early-season predictions of a long parade of storms, a puzzling mid-season lull, and late-season destruction.
The season’s Accumulated Cyclone Energy (ACE) was below normal for the first time in six seasons.
Since it was a La Niña summer, most forecasters were bullish about the number of storms and hurricanes in the Atlantic due to anticipated favorable wind shear and unusually warm ocean water. Instead the summer defied expectations, in large part due to dry air, a persistent flow of dusty Saharan air that lowered humidity levels in the basin.
“While La Niña typically decreases tropical Atlantic and Caribbean vertical wind shear, wind shear was elevated across the Caribbean in both August and October,” Colorado State University hurricane researcher Philip Klotzbach said in an end-of-season analysis issued Monday. “The complete lack of activity in August 2022 was the biggest surprise of the 2022 season.”
Preseason predictions were more off the mark than usual. On May 24, NOAA’s initial forecast called for 14-21 named storms, six to 10 hurricanes and three to six majors. The agency’s August updated forecast was only slightly paired back, in part because we had no tropical activity at all from July 2 to September 1.
Colorado State University, widely reported by the media, was more on the mark with its December 9, 2021 forecast of 13-16 storms than it was in the April forecast of 19 named storms.
In the end, the blue ribbon goes to the University of Arizona, which predicted on April 14 that the Atlantic would see 14 named storms, seven hurricanes and three majors. The university’s accuracy will not go unmentioned next April, but with so many shifting variables due to climate change, preseason forecasts may be less reliable in the future as nature pursues its complex twists and turns.
Florida’s coasts were under the gun three times with what eventually became Tropical Storm Alex in early June, Huricane Ian in late September, and Hurricane Nichole during the second week of November.
Hurricane Ian was hands-down the most costly and deadly storm of the season, pounding Cuba and following that up with a brutal hit to Florida’s southwest coast. It caused more than $50 billion worth of damage and killed at least 157 people, unleashing its destructive forces far into Central Florida and the east coast.
Ian will go into the books as a strong Category 4 with sustained winds of 155 mph, unless the National Hurricane Center does some reanalysis off season (as it did with Andrew in 1992) and determines that it did in fact cross that Category 5 threshold.
Just a week earlier, Hurricane Fiona pounded the Caribbean causing at least $2.88 in damage and 31 deaths. It devastated Puerto Rico, dropping almost 3 feet of rain in some areas and triggering massive flooding.
Ian caused similar misery in Florida, dropping a foot of rain in Orlando and as much as 2 feet in and around New Smyrna Beach on the east coast.
Ian was the fifth-deadliest hurricane to hit the U.S. since 1963, according to Yale Climate Connections.
What made things worse with Ian is that the track became unpredictable. Forecasters seemed to have settled on a track into Florida north of, or around Tampa, but Ian instead took a southern route into the Fort Myers area, a track that had been predicted earlier by the European forecast model.
NHC forecasters had indeed emphasized the uncertainty in Ian’s track.
In November, Hurricane Nichole hit Grand Bahama and made landfall near Vero Beach as a Category 1. Probably its biggest impact was beach erosion on Florida’s east coast.
Eroded beach continues to be a problem as we head into the Christmas season, even far to the south of where Nichole made landfall.
What will 2023 look like? It’s anybody’s guess. We might assume that another La Niña summer is unlikely, so maybe we’ll finally catch a break.
But as forecasters say — and as we found out again this season — all it takes is one destructive landfall to make it a bad season.
