An upper level disturbance moving through Southern California will result in a few scattered showers and thunderstorms over southern Monterey and San Benito counties through this evening. Elsewhere around the district will remain dry. Marine layer along the coast will move inland again tonight. One more day of cooler weather on Friday before high pressure brings warmer and drier conditions this weekend. Note : All winds are 20-foot Winds Unless otherwise specified. Thunderstorms imply strong, gusty and erratic winds. ...Discussion from Los Angeles/Oxnard... ...MODERATE RISK OF SIGNIFICANT FLASH FLOODING AND DEBRIS FLOWS OVER SOME MOUNTAINS AND VALLEYS THROUGH TONIGHT, FLASH FLOOD WATCH ISSUED... ...CHANCE OF SHOWERS AND THUNDERSTORMS THROUGH FRIDAY... An unseasonable low pressure system, currently 50 miles west of Point Conception, will swing through southwest California into Friday. This will result in continued cool and moist conditions through Friday. This system is unstable and will carry chances for thunderstorms over most areas with locally heavy rain. The focus through tonight will be over San Luis Obispo, Santa Barbara, and Ventura Counties, with the greatest risks over the interior areas where there is a moderate risk of rain rates exceeding 1 inch per hour. Rain this intense would be capable of producing significant debris flows over recent burn areas, including the Hurricane, Apache and Lake burn scars. As the system moves east into Friday, the shower and thunderstorm activity will decrease but not go away. While the risk is low for debris flows over the Post and Bridge burn scars on Friday, it is not zero and will continue to be assessed. Coastal and valley areas also have a chance for rain and thunderstorms, but the risk for heavy rain is low. Winds will shift from southerly to northerly tonight and Friday as the low moves through. High pressure will quickly build aloft over the weekend, with steady and significant warming and drying into early next week. $$ ECC028-201645- Santa Barbara County excluding Los Padres National Forest- Discussion for Santa Barbara ECC Dispatch 335 PM PDT Thu Sep 19 2024 ...MODERATE RISK OF SIGNIFICANT FLASH FLOODING AND DEBRIS FLOWS OVER SOME MOUNTAINS AND VALLEYS THROUGH TONIGHT, FLASH FLOOD WATCH ISSUED... ...CHANCE OF SHOWERS AND THUNDERSTORMS THROUGH FRIDAY...
