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.”
