Rain began falling across Santa Barbara County on Sunday afternoon, but forecasters say the latest weather system will be much weaker than the storms that hammered the region last week.

Most coastal and valley areas are expected to receive a half-inch to an inch of rain overnight into Monday, according to Kristan Lund, a meteorologist with the National Weather Service in Oxnard.

Foothill and mountain areas could see 1-2 inches of rain, she said, adding that most of the precipitation should be over by the time people wake up on Monday.

However, a 60% chance of scattered showers remains in the forecast until Monday night.

“This storm is definitely weaker than the last one,” Lund told Noozhawk.

She said mostly clear skies are expected Tuesday through the weekend, although there is a slight chance of showers on Thursday.

Daytime high temperatures should be in the upper 50s, with overnight lows around 40.

A wind advisory was issued for the county, in effect from 6 p.m. Sunday until 2 a.m. Monday, calling for southwest winds of 15-25 mph, with gusts to 40 mph.

There also are high surf and coastal flood advisories in effect until 10 p.m. Tuesday.

Forecasters were warning that some local beaches, mainly in the North County, could see large breaking waves of 8 to 14 feet, with dangerous rip currents.

“Flooding of sea water is likely, around the time of high tide, over vulnerable low-lying coastal areas such as parking lots, beaches and walkways,” according to the advisory.

“Significant damage to roads or structures is not expected.”

High tides will be at 4:17 a.m. and 6:12 p.m. Monday, and 5:05 a.m. and 7:26 p.m. Tuesday.

With continued storm runoff, Lake Cachuma had risen to 88.6% of capacity as of 10 p.m. Sunday, and was less than 8 feet below its spill level, according to the county Public Works Department.

The U.S. Bureau of Reclamation, which manages the reservoir, said Sunday afternoon that it canceled flood control/storage management water releases from the lake planned for Saturday.

“Our team is closely watching conditions at Lake Cachuma,” the department said in a tweet. “We will continue to provide updates.”

Efforts were continuing around the clock throughout the county to clear creeks and debris basins of mud and rocks.

Highway 154 remained closed Sunday evening between Foothill Road near Santa Barbara and Highway 246 in the Santa Ynez Valley, while Caltrans crews continued to remove mud and rocks from the roadway.

Caltrans also announced Sunday night that it had closed the section of Highway 154 between Alamo Pintado Avenue and Caulkins Road in Los Olivos for a storm-related inspection of the Alamo Pintado Creek bridge.

South Patterson Avenue in Goleta was shut down late Saturday between Highway 101 and Hollister Avenue after a large tree fell and took down two power poles.
