La Nina could soon arrive. Here's what that means for winter weather
NOAA’s Climate Prediction Center reports there is a 60% chance that a weak La Nina will develop this autumn and could last until March
The National Oceanic and Atmospheric Administration’s Climate Prediction Center says there is a 60% chance that a weak La Nina event will develop this autumn and could last until March.
La Nina is part of a natural climate cycle that can cause extreme weather across the planet — and its effects vary from place to place.
Although there is no guarantee how this La Nina will play out, there are some general trends. Experts say northern parts of South America could see more rain than usual. Southern regions of the U.S. and parts of Mexico could be drier than average. The northern tier of the U.S. and southern Canada could be wetter than average.
La Nina is the cool phase of the El Nino-Southern Oscillation, a naturally occurring global climate pattern that involves changes in wind and ocean temperatures in the Pacific and can cause extreme weather across the planet.
