The number of hurricanes that develop in any given year varies, and this year, NOAA’s Climate Prediction Center is forecasting a “near normal” season in the Atlantic.
Tropical cyclones, known as hurricanes in the United States, develop around the globe at different times of the year. In this country, we are most affected by the Atlantic hurricane season, which impacts the North Atlantic Ocean, Caribbean Sea, and Gulf of Mexico. It runs from June 1 through November 30.
Overall, NOAA predicts a 70% likelihood of ten to sixteen named storms forming this season, of which four to eight could become hurricanes, including one to four major hurricanes. A major hurricane is one that is rated category 3 or higher.
The numbers for this season’s outlook include Hurricane Alex, the unusual storm that developed in the eastern Atlantic in mid-January.
One of the main drivers behind this season’s average to slightly above average forecast is the diminishing presence of El Niño and the likely development of La Niña in the autumn. El Niño conditions tend to suppress tropical activity in the Atlantic while La Niña conditions do the opposite.
After three consecutive below average hurricane seasons in the Atlantic, a normal season will likely feel very active. But regardless of the number of storms that actually form, it is important to remember that it only takes one landfalling system in your community to make it a memorable season.
