摘要

Washington-The 2009 Atlantic hurricane season, which officially ended November 30, had the fewest named storms since 1997, thanks in part to El Nino conditions that developed in mid-summer, the US National Oceanic and Atmospheric Administration said. NOAA said nine named storms formed this year, including three hurricanes, two of which were major hurricanes of Category 3 strength or above. The agency said these numbers fell within the ranges predicted in its mid-season outlook issued in August, which called for seven to 11 named storms, three to six hurricanes, and one to two major hurricanes.
