NEW YORK (Reuters) -- El Nino, an extreme warming of equatorial waters in the Pacific Ocean that wreaks havoc with world weather conditions, has formed and will last into 2007, the U.S. National Oceanic and Atmospheric Administration said Wednesday.
El Nino has already helped make the Atlantic hurricane season milder than expected, said a NOAA forecaster.
"The weak El Nino is helping to explain why the hurricane season is less than we expected. El Ninos tend to suppress hurricane activity in the Atlantic," said Gerry Bell, a hurricane forecaster for NOAA.
The NOAA's Climate Prediction Center said the El Nino probably will spur warmer-than-average temperatures this winter over western and central Canada and the western and northern United States.
It said El Nino also will cause wetter-than-average conditions in the U.S. Gulf Coast and Florida, and spark dry conditions in the Ohio valley, the Pacific Northwest and most U.S. islands in the tropical Pacific.
