Bands of rain sweeping through Riverside County Tuesday triggered flooding on multiple roads, which were made impassable and closed to traffic.

The cold trough of low pressure lurching across the region produced downpours in the San Jacinto and Temecula valleys, as well as the eastern half of the county.

Crews from the county Department of Transportation were summoned to trouble spots by California Highway Patrol officers and sheriff’s deputies.

At 1:30 p.m., heavy rain led to standing water on Bridge Street in Nuevo, and crews shut down a segment of the artery between Fernandez and Gilman Springs roads.

A half-hour later, crews also shut down Leon Road, between Domenigoni Parkway and Olive Avenue, just east of Menifee.

About 3:50 p.m., roadway flooding forced the closure of Pico Avenue, between Central Avenue and Nuevo Road, just east of Perris.

No motorists were stranded as a result of the floods.

The National Weather Service posted a Flash Flood Watch that remains in effect until 7 p.m. Thursday.

Forecasters said the chance for precipitation in the western county region is 80% going into Thursday afternoon. Rainfall amounts are expected to vary between a quarter to a half inch on Wednesday and Thursday in the Riverside metropolitan area, according to the NWS.

The storm system will make its exit to the east Friday, with partly sunny conditions through the weekend, according to the Weather Service.
