Rain Outlook for the Holiday Week

Rain is expected to start on Tuesday in the Los Angeles area and will continue through the weekend, with the wettest day projected to be Wednesday. The forecast calls for less than a half-inch of rain on Tuesday before rates pick up on Tuesday night and Wednesday. During the height of the storm on Wednesday, hourly rain rates could exceed 1 inch per hour, making the day the most intense of the week.

Road Closures in Malibu and Topanga

The city of Malibu has announced several closures that will begin at 8 p.m. on Tuesday.

  • Malibu Canyon Road: A soft closure (emergency vehicles only) will affect the stretch between Francisco Ranch Road and Adamson Flats Road, as well as the area just south of Piuma Road.
  • Tuna Canyon Road: A full closure will be in place between approximately 2870 Tuna Canyon Road (the gate) and Pacific Coast Highway.

In unincorporated Topanga, a 3.6-mile portion of Topanga Canyon Boulevard/State Route 27 between Pacific Coast Highway and Grand View Drive will close at 9 p.m. on Tuesday.

City of Malibu Statement

“Both roads will remain closed until rain subsides and crews can safely clear debris and reopen the roadways,” the city of Malibu said in a statement. “Drive cautiously, watch for mud, rock and water in the roads, keep headlights on, watch for workers and work vehicles. Come to a complete stop at any malfunctioning traffic signal under CA law.”

Flood Watch and Hazards

A flood watch was issued for Tuesday afternoon through Wednesday evening for much of Los Angeles County. The watch highlights the potential for mud and debris flows in foothill and mountain areas, including recent burn scars that may be more vulnerable to erosion.
