2014 Atlantic Hurricane Season Forecast

The 2014 hurricane season has arrived and the extended range summer analysis forecasts below-average activity and landfall strike possibility.

“We continue to foresee a below-average 2014 Atlantic hurricane season. The tropical Atlantic remains slightly cooler than normal, while El Niño is in the process of developing. However, the transition to El Niño has slowed some in recent weeks, and the tropical Atlantic has anomalously warmed, causing us to increase our forecast slightly. We are still calling for a below-average probability of United States and Caribbean major hurricane landfall.”

Drs Philip J. Klotzbach and William M. Gray, Colorado State University, June 2, 2014

Major hurricanes (>111mph winds)  1   2

Information obtained through May 2014 indicates that the 2014 Atlantic hurricane season will have less activity than the median 1981-2010 season. The probability of U.S. major hurricane landfall is estimated to be about 80 percent of the long-period average. An anticipated below-average Atlantic basin hurricane season is due to the likelihood of El Niño development along with a slighter cooler than normal tropical Atlantic.

2013 Atlantic Hurricane Season Forecast

The 2013 Atlantic basin hurricane forecast from Drs. Philip J. Klotzbach and William M. Gray at the Department of Atmospheric Science, Colorado State University in Fort Collins, Colorado, was released April 10. The forecast anticipates enhanced activity compared to 1981-2010 climatological averages.

“The tropical Atlantic has anomalously warmed over the past several months, and it appears that the chances of an El Niño event this summer and fall are unlikely. We anticipate an above-average probability for major hurricanes making landfall along the United States coastline and in the Caribbean.”

Tropical Storm Isaac Effect On Anna Maria Island

All eyes were on the tropics last week as a depression formed into the named storm Isaac, which soon became tropical storm strength and headed into the Caribbean towards Hispaniola. Haiti took the first hit with heavy rains and flooding. Cuba was next in line with high surf and over-wash on the northern coast.

As Isaac continued unsubdued by land and on over the warm waters of the Florida Straights, intensification appeared likely but lack of vertical alignment of the core left the center ill-defined and passed by Key West with relatively little impact.

Meanwhile, Tampa prepared for the Republican Party national convention in the coming week but switched over to storm mode. The forecast path would bring Tropical Storm Isaac up the Gulf of Mexico coastline and risked dangerous consequences for the low-lying city and convention visitors.

Tropical Storm Debby Flooding

Tropical Storm Debby formed off the Gulf Coast June 23 northwest of Tampa with a poorly defined center and no obvious direction of travel. But as the wind field grew wider while it remained almost stationery, the effects of the tropical moisture with persistent rainfall and wind wore away the resistance of beaches and its inhabitants.

By Monday June 25, constant battering by 20 – 40 mph wind and 10″-16″ of rain took its toll on shorelines and low lying property. Combined with high tides, a 2-3 foot storm surge poured over seawalls, rose up through storm drains and flooded streets and yards. Tropical Storm Debby wind field

Saturated ground had nowhere to drain. Streets and yards remained covered with water even as the tide dropped but the surge raised the sea-level. Onshore wind pushed the sea state higher over the shore. Softened soil and gusty winds uprooted some trees and sent limbs and palm fronds flying.
