Mild La Nina Forecast for Spring
WASHINGTON (AP) - A La Nina, a mild cooling of the tropical Pacific Ocean which can affect weather in other areas, is being forecast for spring.
La Ninas tend to encourage wet weather in the Pacific Northwest and dry conditions in the south, but National Oceanic and Atmospheric Administration forecasters declined to blame current weather on the phenomena.
La Nina is the opposite of the better known El Nino, a Pacific warming. Both occur every few years and can affect weather around the world. The last La Nina occurred in 2000-2001.
Because the La Nina is only just starting to develop and is expected to be weak, forecasters at the NOAA Climate Prediction Center said it is too early to say how it will affect spring and summer weather.
