La Nina present, 75 per cent chance seen through 2020 winter

Reuters — La Nina conditions were present in August, and have a 75 per cent chance of continuing through the Northern Hemisphere winter of 2020-21, a U.S. government weather forecaster said on Thursday.

The La Nina pattern is characterized by unusually cold temperatures in the equatorial Pacific Ocean.

A borderline moderate La Nina event is favoured during the peak November-January season, the National Weather Service’s Climate Prediction Center (CPC) said in its monthly forecast.

The weather phenomenon last emerged during September-November season in 2017 and lasted through early 2018.

Anomalies known to occur during La Nina include colder-than-normal temperatures on the Prairies and above-average precipitation in British Columbia, Ontario and Quebec, according to Environment Canada.
