NOAA Issues La Nina Watch

The U.S. Climate Prediction Center (CPC), a division of the National Oceanic and Atmospheric Administration (NOAA), says that the Pacific Ocean equator temperatures have at least a 50% chance of cooling to La Nina values by December. Accordingly, the CPC issued a La Nina watch Sept. 14. In issuing the watch, CPC details noted an emphasis on subsurface cooling in the equator region waters of the Pacific.
