WSI Aces Major Hurricane Forecast Numbers

Weather Authroity Achieves High Marks Overall for Most Recent Set of Seasonal Atlantic Tropical Forecasts

Andover, MA, December 1, 2010 — The 2010 Atlantic tropical season drew to a close yesterday, and the final numbers were rather impressive. A total of 19 named storms, 12 hurricanes, and 5 major hurricanes developed during the season. During the satellite era, the number of named storms and hurricanes in 2010 has been exceeded only by the 2005 season, when 28 named storms and 15 hurricanes occurred.

WSI (Weather Services International) predicted 18 named storms, 10 hurricanes, and 5 major hurricanes in its last preseason forecast in late May. By late July the WSI numbers were 19/11/5, a nearly perfect forecast.

The 2010 numbers were well above both the long-term (1950-2009) averages of 10 named storms, 6 hurricanes, and 2 intense hurricanes and the more active recent 15-year period (1995-2009) average of 14/8/4. The WSI prediction for an increased risk of hurricanes along the eastern US coast was somewhat validated by the very close approach of Hurricane Earl.

“After a relatively slow start, the 2010 tropical season ended with a bang, validating our rather extreme forecasts,” said Dr. Todd Crawford, WSI Chief Meteorologist. “A combination of incredibly warm tropical Atlantic sea surface temperatures along with relatively light wind shear due to a rapidly developing La Nina event enabled this very active season. The lack of hurricane landfalls in the US was due to a combination of good fortune and an unusually persistent atmospheric pattern in the North Atlantic, which consistently helped to steer hurricanes away from the eastern US coast.”

Energy traders, insurance professionals and risk managers look to WSI for accurate, timely weather information around the clock and across the globe. The first look at the 2011 tropical season will be issued on December 22.
