Southern California faces significant flood threat
The threat for flooding is expected to continue through Friday in Southern California.
OXNARD, Calif. – Southern California continues to face a dangerous flood threat through Friday as heavy rain targets the Los Angeles and San Diego areas, before moving eastward.
More than 20 million people from Southern California through central Arizona remain under a Flood Watch as rainfall totals surpassed 10 inches in several mountain areaswhile bringing a month’s worth of rain in an hour in Ventura County.
The overall rainfall amounts combined with the potential for bursts of thunderstorm-triggered heavier rain, especially over recent wildfire burn-scar areas, prompted NOAA’s Weather Prediction Center (WPC) to put a swath of Southern California in a Level 3 out of 4 risk zone for flash flooding.
For many communities, the precipitation is the heaviest rainfall event since the remnants of Hurricane Hilary impacted the region in August.
Some of the hardest hit areas included Oxnard and Santa Barbara, where water rescues were needed.
A good Samaritan driver pulled two people from a vehicle before it was swept away and the American Red Cross opened at least one shelter.
