Cooler than normal temperatures continue today and tomorrow with a slight chance of rain today over southern Monterey County. The potential for some light rain along with good RH recovery and retention the next couple of days will keep fire weather concerns low. 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 INTERIOR MOUNTAINS AND VALLEYS TODAY, FLASH FLOOD WATCH ISSUED... ...CHANCE OF SHOWERS AND THUNDERSTORMS THROUGH FRIDAY... An unseasonable low pressure system, currently 50 miles west of Morro Bay, 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 today 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, especially for the Hurricane and Apache burn scars. The Lake Fire is also of concern, but the risk is lower. As the system moves east tonight and Friday, the shower and thunderstorm activity should decrease but still remain in a more localized nature. 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, but the risk for heavy rain is very low. Winds will be light tonight, then increase on Thursday and Friday with a significant wind shift from southeast to northwest 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. $$ ECC028-201100- Santa Barbara County excluding Los Padres National Forest- Discussion for Santa Barbara ECC Dispatch 1000 AM PDT Thu Sep 19 2024 ...MODERATE RISK OF SIGNIFICANT FLASH FLOODING AND DEBRIS FLOWS OVER SOME INTERIOR MOUNTAINS AND VALLEYS TODAY, FLASH FLOOD WATCH ISSUED... ...CHANCE OF SHOWERS AND THUNDERSTORMS THROUGH FRIDAY...
