A fresh swath of rain across Southern California has already triggered some debris flows and prompted rescues from creeks and storm drains.
This late-season storm, which is expected to last through Thursday, is bringing heavy rainfall and cold temperatures, with highs in the upper 50s to low 60s.
Flood advisories are in effect for Santa Barbara, Ventura and Los Angeles counties. Rainfall rates of a quarter-inch to a half-inch per hour could cause urban flooding and potentially minor mud flows near burn areas, according to the National Weather Service.
Record-breaking rainfall Monday poured down in downtown Los Angeles. The old record for this day was 0.58 inches which occurred in 1958, but as of noon today rainfall was at 1.10 inches.
There’s already been one debris flow in the Hollywood Hills. About 40 to 50 feet of hillside below Lechner Place slid down into the backyard of a home. There were no injuries and no damage to the home itself, but the Los Angeles Fire Department is encouraging those at home to prepare for the wet weather in at risk areas.
Three left lanes of WB I-210 just west of Arroyo Blvd. in Pasadena were closed after a major accident this morning but opened back up as of 12:55 pm.

In Ventura County, firefighters rescued four people trapped by a fast-moving Santa Paula Creek by hoisting them out via a helicopter. The creek rose and picked up speed as Monday's storm dumped more than an inch of rain in the area, causing the individuals to become trapped on a bit of dry land near where the creek feeds into the Santa Clara River.
FINAL UPDATE #Telegraph Swift Water Rescue operations complete. A total of four people hoisted from an island to safety. One victim transported to the hospital with a minor injury from an earlier incident. Crew being released. @VCFD @VenturaCityFD pic.twitter.com/3oGYaoTcQz
