(Reuters) – A U.S. government weather forecaster on Thursday forecast the development of La Nia pattern during the August-October season, which is expected to persist through the remainder of 2020.
There is about 50-55% chance of La Nia developing during the northern hemisphere fall, with a 50% chance it will continue through winter 2020-21, the National Weather Service’s Climate Prediction Center (CPC) said in its monthly forecast.
The La Nia pattern is characterized by unusually cold temperatures in the equatorial Pacific Ocean and linked with floods and drought. The weather phenomenon last emerged during September-November season in 2017 and lasted through early 2018.
Meanwhile, the current El Nio-Southern Oscillation (ENSO) neutral conditions are expected to continue through the summer of 2020, according to the CPC.
ENSO-neutral conditions refer to those periods in which neither El Nio nor La Nia are present, often coinciding with the transition between the two weather patterns.
