NOAA: 2017 Hurricane Season Forecast Updated To Most Active In 7 Years


NOAA has updated its 2017 Atlantic Hurricane Season outlook due to several early-season tropical cyclones that have already occurred this year.


In just the first nine weeks of this season there have been six named storms, which is half the number of storms during an average six-month season and double the number of storms that would typically form by early August. 

An average Atlantic hurricane season, which runs from June 1-November 30, produces 12 named storms, of which six become hurricanes, including three major hurricanes.

Forecasters are now predicting a higher likelihood of an above-normal season, and they increased the predicted number of named storms and major hurricanes. 

According to NOAA, the 2017 Atlantic Hurricane Season has the potential to be extremely active, and could be the most active since 2010.

Forecasters now say there is a 60-percent chance of an above-normal season with 14-19 named storms and 2-5 major hurricanes.

“We’re now entering the peak of the season when the bulk of the storms usually form,” said Gerry Bell, Ph.D., lead seasonal hurricane forecaster at NOAA’s Climate Prediction Center. “The wind and air patterns in the area of the tropical Atlantic and Caribbean where many storms develop are very conducive to an above-normal season. This is in part because the chance of an El Nino forming, which tends to prevent storms from strengthening, has dropped significantly from May.”

The Atlantic basin has seen six named storms (Arlene in April; Bret and Cindy in June; Don and Emily in July; and Franklin in August). Two of these storms, Cindy and Emily, struck the United States. Cindy made landfall on June 22 at the Louisiana-Texas border and caused heavy rain, inland flooding and multiple tornado outbreaks. Emily made landfall on July 31 in Anna Maria Island, Florida. Franklin is predicted to make landfall in Mexico overnight as a hurricane.
