WSI: Lack of Impending El Nino and Warm North Atlantic Ocean Temperatures Suggest Another Active Hurricane Season

Weather Authority Forecasts an “Active-Normal” Season with Threat of Multiple Landfalls; East Coast Under Greatest Threat

ANDOVER, Mass. (May 23, 2013) — Weather Services International (WSI) continues to expect another active tropical season this year, with 16 named storms, nine hurricanes, and five intense hurricanes expected (16/9/5). This compares to the 1950-2012 normals of 12/7/3 and the more recent “active period” (1995-2012) normals of 15/8/4. These numbers have not changed relative to our April release.

According to WSI Chief Meteorologist Dr. Todd Crawford:
“In general, there has been very little change to the outlook for the upcoming tropical season since our April release. Warm North Atlantic sea surface temperatures are still in place, suggesting another active Atlantic tropical season is in store. We are more confident that there will not be a significant El Nino event this summer, which will also result in a favorable environment for tropical development. Our proprietary statistical models and the various dynamical all indicate a season typical of those in the recent active period that began in 1995.”

“Our forecast still calls for 16 named storms, nine hurricanes, and five intense hurricanes. As always, how many storms will make landfall and where they do so is a much more difficult question. Most seasons (80%) have at least one hurricane landfall along the US coast, and most landfalls occur along the Gulf Coast and in Florida. Landfalls in the Northeast are relatively rare, however, occurring on average in just one of every four seasons. However, recent trends in steering currents during the tropical season suggest at least a slightly increased threat of storms along the East Coast again this year and a reduced threat, relative to normal, in the Gulf.”
