Though Tropical Storm Ivo May Trigger Showers in SoCal, Claremont, La Verne Likely to Stay Dry

An influx of moisture from the remnants of Tropical Storm Ivo may trigger showers and thunderstorms in Southern California Monday, raising the threat of flash flooding in the Antelope Valley and the San Gabriel Mountains, forecasters said.

Any storm that develops Monday will be slow-moving, according to a National Weather Service advisory.

"As  result, there is a potential for heavy rainfall and flash flooding. In addition, there will be a threat of debris flows below recently burned areas," it said.

A flash flood watch will be in effect from 1 p.m. through this evening in the Antelope Valley and the San Gabriel Mountains in Los Angeles County. Showers are expected elsewhere in the region, especially in the evening.

"Excessive runoff from heavy downpours may cause rapid filling and overflowing of normally dry washes and small creeks and low-lying areas," the advisory warned. "In addition, there will be a threat of mud and debris flows if thunderstorms affect recent burn areas ..."

Here in Claremont and La Verne, though, the forecast calls for only a slight change of showers and thunderstorms.

Both cities had similar forecasts from the National Weather Service, indicating that the change of rain will remain in town through Tuesday.

Here's what you can look forward to: 

• Monday Afternoon:  A 20 percent chance of showers and thunderstorms. Mostly sunny and hot, with a high near 99. Southwest wind 5 to 10 mph.
