NOAA's Climate Prediction Center (CPC) announced Thursday that water temperatures in critical parts of the Pacific Ocean had finally reached the threshold required for La Niña to emerge in December.
A weak La Niña is forecast to appear this winter and affect weather patterns across the country, likely bringing drier-than-average conditions in much of the Southwest and wetter-than-average ...
For Chandler Price, meteorologist with the National Weather Service in San Diego, these extreme weather events are both typical and unusual for a La Niña winter, a natural climate cycle that can cause extreme weather across the planet. In California, it means a wetter than average northern region and a drier south.
El Niño finally lost its grip on global weather in June, but La Niña’s arrival was delayed repeatedly, leaving an extended period of neutral conditions in place through the summer and fall.
Across Alaska, El Niño events do not have a correlation towards dry or wet conditions; however, La Niña events lead to drier than normal conditions.During El Niño events, increased precipitation is expected in Southern California, Arizona, and New Mexico due to a more southerly, zonal, storm track over the Southwest, leading to increased winter snowpack, but a more subdued summer monsoon ...

The Santa Anas are katabatic winds (Greek for "flowing downhill") arising in higher altitudes and blowing down towards sea level. [7] The National Weather Service defines Santa Ana winds as "a weather condition [in southern California] in which strong, hot, dust-bearing winds descend to the Pacific Coast around Los Angeles from inland desert regions".
The 2020–2023 La Niña event was a rare three-year, triple-dip La Niña. [1] The impact of the event led to numerous natural disasters that were either sparked or fueled by La Niña. La Niña refers to the reduction in the temperature of the ocean surface across the central and eastern equatorial Pacific, accompanied by notable changes in the ...
