Soaker of a Sunday for the Southwest

July 25, 2021
UPDATED By WeatherBug Meteorologists
Heavy monsoonal showers and thunderstorms continue to drench the Southwest and the southern Rockies, elevating the flash flood threat.

A stream of moisture coming off the Gulf of Mexico into the Desert Southwest will continue to provide fuel for rounds of showers and thunderstorms. In addition, an upper-level disturbance will provide more lift for storms to fire. 

Given the warm, unstable air mass, any storms that fire may produce heavy rain. The storms will also likely move very slowly as the winds at the surface and above are very light. 

Repeated heavy downpours have prompted Flash Flood Watches and Warnings to be issued over much of Arizona and southwestern Utah. 

Cities most at risk include Flagstaff, Phoenix and Tucson, Ariz., and St. George, Utah. This includes Zion and Bryce Canyon National Parks.

The heaviest rainfall on Saturday came over central Arizona, and south central Colorado with local rainfall reaching up to four inches. Elsewhere, about one to two inches of rain fell on spots of western New Mexico and southwestern Utah. An additional 2-4" with locally higher amounts will be possible today, mainly over central Arizona.

Make sure to avoid flooded roadways if you have to travel out today. It only takes a few inches of running water to render a vehicle dangerous to operate. Remember the phrase, “Turn Around, Don’t Drown” should you come across floodwaters.
