Rain Will Likely Hit LA Through Thursday

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.
