A strengthening El Niño is shifting the odds toward wetter-than-average conditions across the southern United States and East Coast during winter 2026–27, according to NOAA. The Climate Prediction Center (CPC) reported that the latest weekly Niño-3.4 sea-surface temperature anomaly had reached +2.4°C (+4.3°F), while warmer-than-average conditions are favored across much of the northern United States.
El Niño strengthened further across the equatorial Pacific in September 2026, and NOAA’s Climate Prediction Center (CPC) said on October 8 that the October–December Relative Oceanic Niño Index (RONI) has an 83% chance of reaching at least +2.5°C (+4.5°F)—a level that would exceed previous El Niño events in its record dating to 1950. The World Meteorological Organization (WMO) separately forecast a Niño-3.4 anomaly of approximately +3.7°C (+6.7°F) for the same period.
El Niño is forecast to strengthen to very strong intensity during late 2026, with the World Meteorological Organization (WMO) indicating an exceptionally high likelihood of nearly 100% that El Niño conditions will persist through February 2027. NOAA’s Climate Prediction Center (CPC) separately gives a greater than 90% chance of a very strong event during Northern Hemisphere fall and winter 2026–27. A very strong El Niño increases the likelihood of major shifts in rainfall and temperature patterns across many regions, although the severity of impacts varies by location and season.
El Niño is present and strengthening across the central and eastern equatorial Pacific, the National Oceanic and Atmospheric Administration (NOAA) confirmed on August 3, 2027.Meanwhile its July strength outlook gives an 81% chance of very strong conditions during October–December 2026. WMO’s August–October 2026 outlook also shows associated shifts in seasonal temperature and rainfall probabilities across multiple regions.NOAA maintains an El Niño Advisory.
El Niño has strengthened significantly over the past month and is expected to intensify through the end of 2026, with NOAA forecasters warning there is now an 81% chance the climate pattern could rank among the strongest El Niño events observed since records began in 1950.
El Niño conditions have developed in the tropical Pacific Ocean and are expected to strengthen through the Northern Hemisphere winter of 2026-27, according to the National Oceanic and Atmospheric Administration (NOAA). The Climate Prediction Center (CPC) issued an El Niño Advisory on June 11, 2026, after oceanic and atmospheric conditions shifted into an El Niño pattern.
A powerful atmospheric river is forecast to impact the western United States between October 25 and 31, 2025, bringing heavy rainfall, mountain snow, and high winds from Northern California to Washington.

NOAA released the latest stats concerning last week’s tornado outbreak in the South. The organization’s current tornado estimate is 305 as of Wednesday, May 4. If this number is correct, it is the largest outbreak in history, surpassing the April 3-4, 1974, outbreak,
