Tropical Moisture Brings Flash Flood Risk to Utah
Tropical moisture is surging into Utah, bringing a significant threat of heavy rain and flash flooding, particularly in southwest and central regions of the state. A Flood Watch remains in effect, with the greatest concerns focused on burn scars, slot canyons, dry washes, and other flood-prone areas. Rainfall rates from thunderstorms could reach 0.5 to 1 inch per hour, with some storms repeatedly impacting the same locations. Gusty southwest winds of 25 to 40 mph are expected west of I-15, and isolated severe thunderstorms with strong wind gusts and small hail are possible in northwest Utah. A cold front moving in from the northwest will clear out moisture by late Sunday night, leading to cooler temperatures for Labor Day.
