NOAA’s Climate Prediction Center says the 2016 Atlantic hurricane season, which runs from June 1 through November 30, will most likely be near-normal, but forecast uncertainty in the climate signals that influence the formation of Atlantic storms make predicting this season particularly difficult.
NOAA predicts a 70 percent likelihood of 10 to 16 named storms (winds of 39 mph or higher), of which 4 to 8 could become hurricanes (winds of 74 mph or higher), including 1 to 4 major hurricanes (Category 3, 4 or 5; winds of 111 mph or higher).
While a near-normal season is most likely with a 45 percent chance, there is also a 30 percent chance of an above-normal season and a 25 percent chance of a below-normal season. Included in today’s outlook is Hurricane Alex, a pre-season storm that formed over the far eastern Atlantic in January.
“This is a more challenging hurricane season outlook than most because it’s difficult to determine whether there will be reinforcing or competing climate influences on tropical storm development,” said Gerry Bell, Ph.D., lead seasonal hurricane forecaster with NOAA’s Climate Prediction Center. "However, a near-normal prediction for this season suggests we could see more hurricane activity than we’ve seen in the last three years, which were below normal.”
In addition, El Niño is dissipating and NOAA’s Climate Prediction Center is forecasting a 70 percent chance that La Niña — which favors more hurricane activity — will be present during the peak months of hurricane season, August through October. However, current model predictions show uncertainty as to how strong La Niña and its impacts will be.
