Residents and officials continued to keep a wary eye on recent burn areas amid fears of possible flooding and mudslides. There was no major flooding reported Wednesday during the daytime.
In Santa Monica, an electrical storm resulted in the closure of the beach and sand areas, according to the city's official Twitter account.
"If on the beach or on the Santa Monica Pier seek shelter indoors until the storm has ended," the tweet said.
Berms were in place at several local beaches, and sandbags lined vulnerable neighborhoods as forecasters predicted up to one inch of rain.

In San Clemente, the Mariposa Point beach trail was closed due to ongoing natural erosion. Some local residents were not happy about the closure, but said they understood that it's a safety concern.
The previous day, bulldozers were building a sand berm in front of beachfront homes. The 14-foot berm goes up every year, as the community learned its lesson in 2014 when swells from Hurricane Marie flooded homes along the boardwalk.

"If you go back historically we've had a lot of standing water back at the homes," said Chris Pierce, with the Seal Beach Marine Safety Department. "That's usually the result of high surf, rain event and high tides combined. When those three things come together we have seen a lot of standing water that has come back to the homes. In recent years though, we've been pretty on it to make sure that doesn't happen."
SAN GABRIEL VALLEY
Duarte and other communities along the 210 corridor were hit hard by fire and flooding a few years ago.
But this fire season they escaped most of the wildfires and the vegetation above vulnerable neighborhoods has grown back.

While K-rails remain in place to contain potential flooding, many residents say they don't expect serious problems.
Some even welcome the rain.
"We need rain," said Duarte resident Taress Clark. "We live in California. I know in past years we've had a shortage of rain and the drought. We need the rain. Bring it on!"

Residents in San Bernardino whose homes are along blackened hillsides are bracing for rain and possible debris flows.
Rain totals are not expected to cause wide spread flooding, but the potential is there. The San Bernardino County Fire Department will be monitoring hillsides for movement and have equipment and firefighters on standby.
"After the fires will always come the rains and that's a big issue because...it's harder to defend against the rain because you don't see it coming," said Jessie Carrillo of San Bernardino.
Carrillo was out surveying the area close to his sister's home Tuesday afternoon. He said even without a burn scar to worry about some areas are prone to flooding.

"Anytime there is elimination of undergrowth you are going to get more water. We are just going to pray it isn't that bad," Carrillo said.
Other residents were not worried.
Mike Hatoum of San Bernardino said he hopes the rain will rid his street and home of the heavy smoke smell left in the wake of the fires.
"It will clean up a little bit and it will bring the ashes and everything down," Hatoum said.
