A much-anticipated rainstorm is set to move into Southern California on Thursday evening and move out by Friday afternoon.

According to the National Weather Service, the rain will be heaviest late tonight and will continue into the Friday morning commute.

A flash flood watch has been issued for burn areas in Los Angeles and Ventura counties.

The storm has already hit Central California, prompting some evacuations in areas that were burned by the Sherpa Fire earlier this year.

Officials expect less than a half-inch of rain in Los Angeles but more to the north, including 2 inches in San Luis Obispo.
