Reuters — There is a 90 per cent chance of the El Nino weather pattern emerging during the Northern Hemisphere winter of 2018-19, a U.S. government weather forecaster said on Thursday.

“The official forecast favours the formation of a weak El Nino,” the National Weather Service’s Climate Prediction Center (CPC) said in a monthly forecast.

The expectation of the weather pattern continuing through spring next year stood at 60 per cent, the CPC added.

Last month, the weather forecaster pegged the chances of the El Nino emerging at 80 per cent during the winter 2018-19 and 55-60 per cent during the spring next year.

Fifty-six per cent chance of more stable, ENSO neutral weather conditions in late summer and fall U.S. forecasters say

More stable weather due to El Niño-Southern Oscillation (ENSO) neutral conditions are likely in the Northern Hemisphere summer of 2025, with a 56 per cent chance in August-October, the U.S. Climate Prediction Center said.

The last El Nino, a warming of ocean surface temperatures in the eastern and central Pacific that typically occurs every few years, occurred from around 2015 to 2016 and caused weather-related crop damage, fires and flash floods.

Historically, milder-than-normal winters and springs are known to occur in Western, northwestern and central Canada during El Nino periods, according to Environment Canada.

Eastern and Atlantic Canada aren’t known to be “significantly” impacted by El Nino events, though such an event may reduce tropical cyclone activity in the Atlantic.
