Flash Flood Watches for Parts of Arizona, California, Nevada and Utah

The National Weather Service issued flash flood watches for parts of four states in the Southwest for late Monday and Tuesday.

Areas covered by watches due to what the weather service’s Las Vegas office calls “abundant tropical moisture from Hurricane Rosa” include southern Nevada, southeastern California, southwestern and central Utah and the western two-thirds of Arizona.

Forecasts call for heavy rainfall in the watch areas, which include Las Vegas, Nev., Phoenix Ariz., and Salt Lake City, Utah with possible flooding in slot canyons and normally dry washes and a potential for debris flows from recent wildfire burn scars.
