Expected to be moderate-to-strong by late fall/early winter
June 8, 2023 - The expected El Niño has emerged, according to scientists at NOAA’s Climate Prediction Center, a division of the National Weather Service. In the monthly outlook released today, forecasters issued an El Niño Advisory, noting that El Niño conditions are present and are expected to gradually strengthen into the winter.
El Niño is a natural climate phenomenon marked by warmer-than-average sea surface temperatures in the central and eastern Pacific Ocean near the equator, which occurs on average every 2-7 years. El Niño’s impacts on the climate extend far beyond the Pacific Ocean.
"Depending on its strength, El Niño can cause a range of impacts, such as increasing the risk of heavy rainfall and droughts in certain locations around the world," said Michelle L'Heureux, climate scientist at the Climate Prediction Center. "Climate change can exacerbate or mitigate certain impacts related to El Niño. For example, El Niño could lead to new records for temperatures, particularly in areas that already experience above-average temperatures during El Niño.”
El Niño’s influence on the U.S. is weak during the summer and more pronounced starting in the late fall through spring. By winter, there is an 84% chance of greater than a moderate strength El Niño, and a 56% chance of a strong El Niño developing. Typically, moderate to strong El Niño conditions during the fall and winter result in wetter-than-average conditions from southern California to along the Gulf Coast and drier-than-average conditions in the Pacific Northwest and Ohio Valley. El Niño winters also bring better chances for warmer-than-average temperatures across the northern tier of the country.
