Post-Tropical Storm Brings Flooding to Southwest
US · Published Oct 11, 2026
• A post-tropical storm is causing significant coastal flooding, heavy rain, and strong winds across the southwestern United States, particularly in California.
• The National Hurricane Center (NHC) has reported that water levels along the California coast are running as much as 1.5 feet above predictions, exacerbated by a near-record strong super El Niño event in the tropical Pacific.

Impact & Risks

The storm has caused major coastal flooding in Southern California, with some areas experiencing water levels 1.5 feet above predictions. Homes have been lost to the sea, and the situation is particularly dire in regions already affected by high waves and tides in recent months. Inland areas, including Arizona, southern Nevada, and Utah, are facing strong wind gusts of 45 to 65 mph, which could lead to power outages, property damage, and hazardous travel conditions. The ongoing super El Niño event is contributing to the elevated water levels, increasing the risk of further coastal damage.
