A fire weather watch has been issued for Saturday in Washington, Iron and Beaver counties in Southern Utah, as well as the rest of the western two-thirds of the state, due to wind and low relative humidity.

Affected areas include Salt Lake Desert, Central Utah West Desert and Color Country West Desert. Southwest winds of 15-25 mph are expected, with wind gusts up to 45 mph.

The fire weather watch is accompanying a red flag warning in effect until Saturday evening. Among the areas impacted include St. George and Cedar City.

A hazardous weather outlook is predicting rain going into the week, as tropical moisture associated with Hurricane Rosa will spread northward into the area. Southern Utah will see the potential for heavy rain as early as Monday. The moist and unstable airmass will remain over the region for much of the week.

With this rain, there will be the possibility of flash flooding, particularly over prone areas such as burn scars, slot canyons, normally dry washes, and urban areas with poor drainage.
