NOAA’s Climate Prediction Center has announced that projected climate conditions point to an above normal hurricane season in the Atlantic Basin this year and a below normal Eastern Pacific season.
Atlantic Basin
The Climate Prediction Center outlook calls for considerable activity with a 65 percent probability of an above normal season and a 25 percent probability of a near normal season. This means there is only a 10 percent chance of a below normal season.
The climate patterns expected during this year’s hurricane season have in past seasons produced a wide range of activity and have been associated with both near-normal and above-normal seasons. For 2008, the outlook indicates a 60 to 70 percent chance of 12 to 16 named storms, including 6 to 9 hurricanes and 2 to 5 major hurricanes (Category 3, 4 or 5 on the Saffir-Simpson Scale).
An average season has 11 named storms, including six hurricanes for which two reach major status.
“The main factors influencing this year’s seasonal outlook are the continuing multi-decadal signal (the combination of ocean and atmospheric conditions that have spawned increased hurricane activity since 1995), and the anticipated lingering effects of La Niña,” said Gerry Bell, Ph.D., lead seasonal hurricane forecaster at NOAA’s Climate Prediction Center. “One of the expected oceanic conditions is a continuation since 1995 of warmer-than-normal temperatures in the eastern tropical Atlantic.”
NOAA’s Atlantic hurricane season outlook will be updated on August 7, just prior to what is historically the peak period for hurricane activity.
Eastern Pacific
The Climate Prediction Center outlook calls for a 70 percent probability of a below normal season, a 25 percent probability of a near normal season, and a 5 percent probably of an above normal season.
Allowing for forecast uncertainties, seasonal hurricane forecasters estimate a 60 to 70 percent chance of 11 to 16 named storms, including five to eight hurricanes and one to three major hurricanes (category 3, 4, or 5 on the Saffir-Simpson scale).
An average eastern Pacific hurricane season produces 15 to 16 named storms, with nine becoming hurricanes and four to five becoming major hurricanes.
