Chance of Afternoon Thunderstorms Again Tuesday

The National Weather Service advised Tuesday morning of the chance of afternoon and evening thunderstorms again in and below the mountains of San Bernardino and Riverside counties, including the San Gorgonio Pass area.

"Mid-level sub-tropical moisture will continue to spread into Southern California today," the Weather Service advised. "Expect a chance for thunderstorms over the mountains and deserts from early afternoon through the evening.

"Although most activity will be limited to the higher terrain, isolated storms may also form over the Inland Empire," a Weather Service update said.

Thunderstorms are expected to develop, and isolated flash flooding is possible, according to the Weather Service. The flash flood potential was described as moderate.

If thunderstorms occur, they could bring heavy rain, small hail and strong winds in some areas, according to the Weather Service.

Areas recently scorched by fires are "particularly susceptible to flash flooding and heavy debris flows," the Weather Service stated.

If you hear thunder, seek shelter, the Weather Service advised.
