El Niño Will Upend Winter Weather in the US. Here’s Who Will Feel It the Most
AccuWeather says the pattern has near 100 percent confidence and could bring wetter conditions to the South and California while drying parts of the North.
On Thursday, AccuWeather reported near 100 percent confidence that a strengthening super El Niño will become the dominant driver of U.S. weather during coming months, carrying a nearly 70% chance by year-end of becoming the strongest on record.
A super El Niño develops when warming in the tropical Pacific reaches unusually high levels, strengthening atmospheric ripple effects that influence weather worldwide. NOAA has said the developing event is already showing signs it could reach the agency's "very strong" category by winter.
Heavy Pacific storm systems could repeatedly target the Sierra Nevadas while delivering healthy snow totals to the central and southern Rockies, while AccuWeather long-range forecaster Paul Pastelok said areas of low pressure in the Southwest and Texas will increase rain and flooding chances starting late October.
Severe weather will start in Florida and southern Georgia in November, with Jacksonville, Tampa and Orlando at risk of tornadoes, as warmer-than-normal temperatures are expected over more than half of the Lower 48 and wetter conditions possible across Southern California and the East Coast.
Meteorologists caution that El Niño is only one factor influencing winter weather and individual storms may still differ from seasonal patterns, while rising temperatures from climate change could shift more precipitation toward rain at lower elevations; Pastelok told Newsweek detailed forecasts remain unfinalized.
By Mary Gilbert, CNN. The growing super El Niño will have major repercussions on the US winter weather. Winter will not only be the time when this El Niño reaches its maximum intensity, but also when its influence on the global climate is most pronounced. El Niño is a natural climate cycle characterized by temperatures
