Goodbye La Nina: Will Drought, Hurricanes Also Go?

Thursday, May 3, 2012

The La Nina weather phenomenon is over. Forecasters say that's good news for the drought in the South and hurricane areas along the coasts.

The National Weather Service pronounced the two-year La Nina finished on Thursday. La Nina is the flip side of El Nino and is caused by the cooling of the central Pacific Ocean. La Nina's greatest effects are in the winter, usually triggering drought in the U.S. South and more rain further north. It also often means more hurricane activity in the Atlantic during the summer. Global temperatures are cooler during La Ninas, especially in the tropics

Meteorologists reported some drought relief in Texas earlier this year. But recently drought conditions intensified again in parts of Texas and much of the Southeast.
