After some tropical activity last week, we're now entering another quiet stretch that will last through this week or longer.
2022 Atlantic Hurricane Season Outlook
Federal meteorologists are forecasting a record-shattering seventh straight unusually busy Atlantic hurricane season.
The National Oceanic and Atmospheric Administration predicted that the summer in the Atlantic will produce 14 to 21 named storms, six to 10 becoming hurricanes and three to six turbo-charging into major hurricanes with winds greater than 110 mph. Even with averages shifting upwards to reflect more active storm seasons in recent decades, these predictions are above the 30-year average of 14 named storms, seven hurricanes and three major hurricanes.
The National Hurricane Center ran out of names for Atlantic storms in the last two years, with a record-setting 30 named storms in 2020 and 21 last year. In the past five years there have been more Category 4 and 5 hurricane landfalls in the United States than in the previous 50 years combined.
Several outside hurricane experts agree with NOAA that the Atlantic conditions are ripe for yet another active hurricane season. They say La Nina reduces wind shear that could decapitate storms. The warmer water — about half a degree warmer than last year in storm-forming areas — serves as hurricane fuel. A reduction in pollution particles in the air has taken away artificial cooling in the Atlantic and a new study links that to increasing storms.
One key indicator, that takes into account the number of storms, how strong they are and how long they last, is called Accumulated Cyclone Energy index or ACE. This year could be as much as double what’s been normal since 1950. The calculation is used when determining what is an average season and what's above average.
The average ACE since 1950 is just shy of 100, while the last six years have ranged from 132 to 225 in 2017.
