On May 27, 2015, the National Oceanic and Atmospheric Administration (NOAA) released its 2015 Hurricane Season predictions. Like other predictions already made this year, the NOAA not surprisingly is forecasting a 70% probability that this season will see below-normal activity. The NOAA forecast adds the 20% chance for near-normal season and a 10% chance for an above-normal season.

The NOAA cites the “persistence and possible strengthening of the already developed El Niño” as the main factor affecting hurricanes. While El Niños come about due to warm water in the Pacific Ocean, this warm water affects wind circulation patterns worldwide.

Tropical storms and hurricanes develop in the calm, warm waters. In the Atlantic Ocean, storm systems form off the west coast of Africa and develop as they head westward to the Caribbean. El Niños contribute to wind shearing in this area, which disrupts and dissipates the heat energy that builds storms. Currently, vertical wind shear is already strong across the region, and this is expected to persist through August into October.

2015 Hurricane Predictions

Seasonal Average
Number of named storms
(winds 39 mph+)
6-11 7 9 > 11 12
Storms becoming hurricanes
(winds 74 mph+)
3-6 3 5 5 6
Major hurricanes
(Cat. 3, 4 or 5, winds 111 mph+)
0-2 1 1 2 3

Another factor hampering hurricanes continues to be below-average sea surface temperatures (SST) in the eastern tropical Atlantic off the coast of west Africa. Even if water temperatures do rise on average, it’s unlikely that storm systems would survive the effects of wind shearing.

Still, it’s best to heed what NOAA Administrator Kathryn Sullivan, Ph.D said about the below-average 1992 season: “A below-normal season doesn’t mean we’re off the hook. As we’ve seen before, below-normal seasons can still produce catastrophic impacts to communities.” The first storm of 1992 was Hurricane Andrew, a Category 5 hurricane that devastated South Florida.

NOAA will issue an updated Atlantic hurricane prediction in early August – just before the season’s historical peak.
