Diamond Bar could see up to 2 inches of rain with Monday’s storm


DIAMOND BAR, CA – Rain started to fall on Diamond Bar and Walnut this morning – the front edge of a system that is expected to drop half an inch to 2 1/2 inches in LA County before moving east around 6 or 7 p.m.

Locally, the rains will not be as intense or destructive as those that hit northern California and the Pacific Northwest, but the now weaker weather system targeting Southland is part of that system.

According to the National Weather Service, the main system front – and the heaviest rainfall – will likely hit the Los Angeles area around noon and move out of the area fairly quickly.

The forecast also foresees the possibility of minor flooding and wind gusts.

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

For most of LA County, between half an inch and 1 1/2 inches of rain was expected Monday, although higher amounts between 2 and 2 1/2 inches could hit the coastal foothills and the foothills of Hallway 210. , said the NWS. .

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. Southerly winds of 15 to 30 mph gusting to 50 were expected in these areas, with isolated and brief gusts to 60 possible in the mountains.

A wind advisory was also issued for the mountains of LA County – excluding the Santa Monica Range – from 4 a.m. to 2 p.m. Monday.

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

The chance of precipitation is expected to drop to 20% Monday night before the skies turn sunny Tuesday, according to the weather service. Temperatures on Tuesday are expected to vary between the mid-60s and the lower 70s.

Santa Barbara officials on Sunday issued evacuation orders for parts of the county in the Alisal Fire burn zone.

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

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