Flood Watches Issued from Phoenix to Dallas
Remnants of Hurricane Polo are driving a widespread flood threat across the U.S., stretching from the Southwest to the Midwest. Heavy rainfall has already triggered flash flooding in Utah and Nevada, according to Marc Chenard of the U.S. Weather Prediction Center. Tropical moisture from Polo is combining with a Pacific low-pressure system, creating conditions for torrential rain over the next three days. Flood watches are in effect for areas including Phoenix, Arizona, and Dallas, Texas. The Weather Prediction Center has issued a moderate risk (level 3 of 4) for excessive rainfall in Arizona, New Mexico, Texas, Oklahoma, Colorado, and Kansas. Rainfall totals could reach up to 12 inches (30 cm) along the coast and 8 inches (20 cm) in southern and central Sonora, Mexico. Source time: Wed, 30 Sep 2026 08:00:57 GMT.
