The La Nina (lah NEEN'-yah) condition in the Pacific Ocean continues to weaken but could still affect weather for the next few months, federal climate scientists reported Thursday.
The periodic cooling of the tropical Pacific is the opposite of the better-known El Nino (el-NEEN'-yo.) Both can affect weather worldwide.
The federal Climate Prediction Center said La Nina impacts through May could include below-average rain or snow across much of the Southern states and the Central Rockies and Central Plains. Also, below-average temperatures are more likely for much of the West Coast and across the Northern tier of states except New England. And there is a possibility of warmer-than-average weather for much of the southern half of the country.
