Utah Gov. Gary Herbert has declared a state of emergency in advance of potential flooding from the remnants of Tropical Storm Rosa.
The National Weather Service on Tuesday issued a flash-flood watch for much of Utah as what remains of the storm moves across the state.

On Monday, Herbert mobilized about 200 National Guard soldiers to prepare for potential flooding south of Salt Lake City.
The soldiers planned to build flood berms and erect barriers and sandbags.
The tropical storm drenched parts of the desert Southwest on Tuesday, trapping drivers on swamped Phoenix streets as authorities prepared for possible flash flooding in Arizona, central Utah and elsewhere.

After soaking northwestern Mexico with heavy rains as it neared the Baja California Peninsula and reportedly claiming at least one victim, Tropical Storm Rosa is expected to drench the U.S. Southwest.
From Arizona to Utah, some residents filled sandbags in anticipation of heavy rainfall forecasts and potential flooding.
The center of Rosa, which was a hurricane until late Sunday, was expected to hit Baja California and Sonora by early Tuesday, bringing 3 to 6 inches (7.5 to 15 centimeters) of rain, the U.S. National Hurricane Center said.
It’s then expected to move quickly northwestward as it weakens, bringing 2 to 4 inches (5 to 10 centimeters) of rain to central and southern Arizona and 1 to 2 inches (2.5 to 5 centimeters) to the rest of the desert Southwest, Central Rockies and Great Basin. Isolated areas might see even more precipitation.
