The National Weather Service in Los Angeles/Oxnard has issued a Flood Watch, effective from 6:00 PM PDT this evening until 6:00 PM PDT Thursday, encompassing a wide array of locations, including the Catalina and Santa Barbara Islands, Santa Clarita Valley, and parts of both Los Angeles and Ventura Counties. According to the alert, the region is bracing for potential flash flooding and debris flows due to expected excessive rainfall.
Today, Los Angelenos are facing rains with a high forecasted near 61 degrees, transitioning to a rainy night with possible thunderstorms post-11 PM and lows around 50, as reported by a detailed forecast from the National Weather Service. The chance of precipitation is pegged at 100%, with new rainfall amounts between three quarters to an inch possible, indicating clear risk for areas, particularly those with recent burn scars. The flood concern will persist through Thursday with a high near 55 and breezy conditions up to 30 mph winds.
The alert emphasizes the susceptibility of recent burn scars within the watch area to hazardous conditions. "Potential for heavy rain over the burn scars may trigger hazardous and damaging flooding and debris flows," cited the National Weather Service. Residents are advised to prepare for heavy showers throughout the period, with peak rates of rainfall reaching 0.5 to 0.75 inches per hour, and a 10 to 20 percent chance of rates exceeding 1.0 inches per hour in certain conditions stimulated by thunderstorms or intense showers.
Residents living in areas notorious for flooding should stay vigilant and be ready to take necessary actions. "You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop," the National Weather Service cautions. After the flood watch expires, the weekend looks more promising with partly sunny skies and a high near 64 on Saturday, before shifting to mostly clear conditions Saturday night.
