Rains expected overnight could potentially trigger rockslides and mudslides in areas ravaged by recent wildfires, National Weather Service forecasters said Wednesday.

The rain was expected to start Wednesday evening, and potentially continue into Thanksgiving morning, according to forecasters. The rain will be accompanied by southwest winds of around 15 miles per hour.

The storm could dump between seven-tenths of an inch and an inch-and-a-quarter of rain on coastal slopes and in the foothills, which could trigger slides over areas burned by the Woolsey Fire in Los Angeles and Ventura counties.

Neighborhoods affected by the Hill fire in Ventura County may also be impacted, forecasters said. 

The Woolsey Fire unified command warned that mud and debris flows “are a very realistic threat to the communities affected by the Hill and Woolsey fires.”

As of Wednesday evening, the Woolsey fire had burned 96,949 acres and was 98 percent contained according to Cal Fire.

The blaze, which began on November 8, claimed three lives.

The Hill fire was 100 percent contained on November 16, after scorching 4,531 acres.

Officials are urging residents, particularly those in the burn areas, to prepare for the storm. 

Sandbag distribution centers have been set up across the region. Residents should also know how to shut off all utilities, and stay away from flood control channels, catch basins, canyons and natural waterways.
