Flood Watch Extended As Rain Persists In Palos Verdes

PALOS VERDES, CA — As the last of this week’s rain falls on the Southland Friday afternoon, the National Weather Service has issued a new warning that streets and low-lying areas are at risk for flooding for the rest of the day.

The NWS Friday morning issued a new flood watch for a wide swath of Los Angeles County, including the Palos Verdes Peninsual, that's in effect until 4 p.m.

"Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Creeks and streams may rise out of their banks. Flooding may occur in poor drainage and urban areas. Extensive street flooding and flooding of creeks and rivers are possible," the NWS said.

Scattered and isolated thunderstorms could continue through the afternoon, with possible periods of heavy rain up to a half-inch per hour, the NWS said.

A previous flood watch for parts of LA County expired late Thursday night.

Early Thursday, Los Angeles County Public Works officials heightened the agency's mudflow warning level for recent burn areas, alerting residents that debris flows are possible. The heightened alert affected recent burn areas in the Topanga Canyon, Agua Dulce, La Tuna Canyon and Duarte areas.

By mid-afternoon, however, the agency dropped all of its mudflow alerts, indicating the threat of such flooding had diminished.

In the Topanga Canyon area, an evacuation warning was issued for roughly 20 homes along Santa Maria Road north of Topanga Canyon Boulevard.

Drivers across the Southland have already been grappling with street flooding in recent days, including on the 101 Freeway. Major streets were closed Thursday in Boyle Heights and North Hollywood, among other locations.
