La Niña develops; colder, wetter winter expected in Montana

Posted: 11/10/2017 17:18:00 -07:00 Updated:

The National Oceanic and Atmospheric Administration has announced La Niña has officially formed in the equatorial waters of the Pacific Ocean.

STORMTracker meteorologist Mike Rawlins says La Niña is a phenomenon that occurs in the Pacific Ocean.

La Niña is characterized by unusually cold ocean temperatures in the Equatorial Pacific, compared to El Niño, which is characterized by unusually warm ocean temperatures in the Equatorial Pacific.

In terms of temperature, much of the nation is likely to see warmer than average conditions.

Cooler than average conditions are expected in Montana and neighboring states.

NOAA says the Great Lakes and northern Rocky Mountains have a 40 percent or greater chance of experiencing higher than average precipitation.

The South is expected to be drier than average.

Despite the call for wetter weather, NOAA says drought conditions are likely to persist in Northern Plains.
