Scattered showers moved through Southern California Monday morning after heavy downpours overnight that put a San Gabriel Valley foothill community under the threat of mud and debris flows.
A flash flood warning was issued in the Glendora area after the National Weather Service forecast a band of "very heavy showers" moving toward eastern Los Angeles County. The community is below a portion of Angeles National Forest where a fire burned about 2,000 acres of brush in January 2014.
There were no reports of significant flooding Monday morning as skies began to clear.
Pockets of showers were reported in the Inland Empire and inland Orange County early Monday, when isolated showers are in the forecast. The National Weather Service forecast rain this morning, setting the chance at 50 percent along the coast, in metropolitan Los Angeles, and in the San Fernando, Santa Clarita and Antelope valleys, and 60 percent in the San Gabriel Valley.

"The roads are going to be wet because of the rain," said NBC4 forecaster Crystal Egger. "Some showers fell at about 3 a.m. in Orange County, so that's where most of the wet roads are going to be."
At 7 a.m., .70 inches of rain fell in downtown Los Angeles. Pasadena reported 1.29 inches and .71 inches fell in Rialto.
No evacuations have been ordered in the Colby Fire burn area early Monday after a night of rain across Southern California. In Silver Lake, a downed tree shattered a car's windshield and brought down power lines.
In the San Gabriel Mountains in Los Angeles and Ventura counties, the storm is expected to generate snowfall through Monday afternoon, with most of the snow falling above 6,000 feet, where between 4 and 7 inches of accumulation are expected. Between 1 and 4 inches of accumulation are expected between 5,000 and 6,000 feet, according to the NWS.
A winter weather advisory, indicating potentially dangerous road conditions, is in effect until 4 p.m.
Earlier, forecasters canceled a flash flood warning for the Camarillo Springs burn area after a strong band of showers that threatened to cause debris flows grew weak. In December, a winter storm caused heavy damage to homes in Camarillo Springs. More than a dozen homes were red-tagged, leaving families displaced.
A flash flood warning for a recent burn area means that flooding and debris flows are imminent or occurring, according to the NWS.
