DIAMOND BAR, CA — Rain began falling in Diamond Bar and Walnut this morning — the front edge of a system that was expected to drop between a half-inch and 2 1/2 inches in L.A. County before moving east around 6 or 7 p.m.

Locally, the rains won't be nearly as intense or destructive as those that hit northern California and the Pacific Northwest, but the now-weaker weather system taking aim at the Southland is part of that system.

The main front of the system — and the heaviest rain — will likely hit the Los Angeles area around noon and move out of the area fairly quickly, according to the National Weather Service.

The forecast also calls for the possibility of minor flooding and gusty winds.

Recent burn areas could experience minor mud and debris flows, but rainfall rates are not expected to create concerns for older burn areas such as the Bobcat or Ranch 2 fires, according to the NWS.

For most of L.A. County, between a half-inch and 1 1/2 inches of rain were expected Monday, though higher amounts of between 2 and 2 1/2 inches could hit the coastal foothills and foothills of the 210 corridor, the NWS said.

Thunderstorms are not expected during the storm.

Wind advisories were also in place from 9 a.m. to 6 p.m. Monday in the Antelope and Santa Clarita valleys. South winds 15 to 30 mph with gusts to 50 were expected in those areas, with isolated and brief gusts to 60 possible in the mountains.

A wind advisory was also issued for the L.A. County mountains — excluding the Santa Monica range — from 4 a.m. to 2 p.m. Monday.

A high surf advisory is in effect at Los Angeles and Orange County beaches from 11 a.m. Monday to 3 a.m. Wednesday.

The precipitation probability was expected to fall to 20% Monday night before skies turn sunny Tuesday, according to the weather service. Temperatures on Tuesday were expected to range from the mid-60s to the lower 70s.

Santa Barbara officials issued evacuation orders Sunday for parts of the county within the Alisal Fire burn area.

The storm was not expected to bring significant snow to the area, with levels remaining well above 8,000 feet, forecasters said.

Cooler temperatures are also expected Monday, with highs in the upper 50s and 60s. Dry and warmer conditions are expected during the rest of the week.
