The National Weather Service in Los Angeles/Oxnard has issued a Flash Flood Warning, effective from 11:48 a.m., including the Malibu area. The warning is in effect until 7:45 p.m. Sunday.
At 11:48 a.m. PDT, Doppler radar and rain gauge reports indicated heavy rain across the warned area. Rainfall rates ranging from 0.5 to 1 inch per hour are anticipated, with the possibility of additional rainfall amounts reaching 1 to 3 inches in the warned region. Heavier rainfall accompanied by embedded thunderstorms is predicted for the afternoon and evening, potentially bringing local rates up to 1.5 inches per hour. Flash flooding is currently occurring or expected imminently.
The impending hazard is characterized by dangerous and life-threatening flash flooding. The primary information source for this warning is radar data. The impact is expected to encompass various areas, including creeks, streams, and typically dry arroyos, with a high likelihood of significant flooding. Urban roadways, particularly in low-lying regions, will experience substantial flooding, and caution is advised for crossings with low water levels. The mountains and canyons could see notable rock and mudslide activity, and there’s a potential for debris flows in recently burned areas.
Locations at risk of flash flooding include Long Beach, Thousand Oaks, Simi Valley, Malibu, Hollywood, Beverly Hills, Universal City, Downtown Los Angeles, Griffith Park, Culver City, Inglewood, Burbank, North Hollywood, Venice, Santa Monica, Van Nuys, Encino, Manhattan Beach, Alhambra, and Hermosa Beach.
Residents and travelers in the warned areas are urged to exercise extreme caution, remain informed through reliable sources, and follow any evacuation orders or safety advisories issued by local authorities. Additionally, the National Weather Service advises the following precautions:
- Turn around, and don’t drown when encountering flooded roads. Most flood deaths occur in vehicles. Be aware of your surroundings, and do not drive on flooded roads.
- In hilly terrain, there are hundreds of low water crossings, which are potentially dangerous in heavy rain. Do not attempt to cross flooded roads. Find an alternate route.
Taking these precautions seriously could save lives and prevent dangerous situations. Stay vigilant, stay informed, and prioritize safety during this flash flood warning.
