Tens of thousands of Californians have been ordered to evacuate as an approaching storm brings the risks of "dangerous flash flooding, mud and debris flow," Santa Barbara County Sheriff Bill Brown said Thursday.
Mandatory evacuations of more than 20,000 people in Goleta, Santa Barbara, Summerland and Carpinteria were effective immediately, Brown said.
The order also includes Montecito, the community where at least 21 people were killed and two people were never found after mudflows in January.
The evacuations were taking place in areas scorched by December's massive Thomas Fire and two other blazes. Mark Olson was outside his home Thursday filling up bags with dirt from January's mudflows.
He and some friends were putting the bags around the garage and setting other sacks to funnel water away from his property.
"We're putting all the debris that came down to use," he said.
"There's a lot of wishful thinking and hope that somehow this time around it's not as devastating as the last (storm in January)."
The National Weather Service office in Los Angeles said 2 to 3 inches of rain could fall through Saturday.
A flash flood watch was scheduled to take effect at 9 p.m. PT for parts of Santa Barbara and Ventura County.
In January this year, California mudslides killed 13 people in the area already ravaged by the biggest wildfire in the States history.
Mudslides, boulders and tons of debris killed at least 13 people in communities along California’s scenic coastline ravaged by a series of intense wildfires.
