An emerging El Nino event — the warming of water temperatures in the central and equatorial Pacific Ocean — will bring warmer-than-normal temperatures to the eastern United States in September and October and could keep much of the West cooler than normal, according to forecasters at Andover, MA-based Weather Services International (WSI).

The continuing La Nina event in the equatorial Pacific Ocean will bring above-normal temperatures to a huge area stretching from the Rocky Mountains to the Mid-Atlantic over the next three months, but it is less clear how it will affect winter temperatures in the Northeast, according to forecasters at the National Oceanic and Atmospheric Administration (NOAA).

A “strong and mature” El Nino — the warming of sea surface temperatures in the central and eastern equatorial Pacific Ocean — persisted during January, but it is likely to fade this spring, increasing the chances for an active Atlantic hurricane season this year, according to the National Oceanic and Atmospheric Administration’s Climate Prediction Center (CPC).

With portions of the Northeast still digging out from a weekend blizzard and another large winter storm looming over the Upper Midwest, Andover, MA-based WSI Corp. released a forecast on Monday — the first official day of winter — calling for temperatures across almost all of the country to average cooler than normal from January to March.

The absence of La Nina and El Nino in the equatorial Pacific Ocean this year has made predicting seasonal weather patterns more challenging, the National Oceanic and Atmospheric Administration (NOAA) said Thursday. Based on other climate patterns, forecasters now expect this year’s winter season to be warmer than normal across the central part of the nation with dryer conditions to continue in the Southeast.
