El Niño is finally waking up. How it may reshape severe weather
A developing El Niño in the Pacific Ocean is showing its earliest atmospheric fingerprints, with scientists detecting shifts in pressure, wind patterns and ocean temperatures that could shape weather across the United States in the months ahead. … While California is not typically in the path of tropical systems, forecasters say warmer ocean waters and more favorable storm tracks can increase the risk of tropical moisture reaching the region. That can translate into heavy rainfall and flash flooding in parts of Southern California, particularly in late-season setups. AccuWeather also warns of an elevated flood risk across the broader Southwest, including Arizona and New Mexico, where remnants of Pacific storms can interact with monsoon moisture and produce intense rainfall far inland.
