A rare triple-dip La Niña is looking increasingly likely for the Northern Hemisphere. The latest outlook by NOAA’s Climate Prediction Center, released Thursday, indicates there’s a 62% to 66% chance the current La Niña climate condition will persist through fall and early winter.

If that happens, it’ll be the third La Niña winter in a row – a rare phenomenon we’ve only seen twice since 1950. A third consecutive La Niña year would likely have a major impact on California.
