590 FNUS56 KLOX 032326 FWFLOX Fire Weather Planning Forecast for Southwestern California National Weather Service Los Angeles/Oxnard CA 326 PM PST Tue Dec 3 2019 ...ACTIVE STORM PATTERN THIS WEEK, MOST SIGNIFICANT ON WEDNESDAY... .DISCUSSION... A low pressure system off the northern California coast will move through southern California on Wednesday, bringing widespread moderate rain and east to southeast wind gusts between 20 and 40 mph to the area. Thunderstorms are possible mainly from Santa Barbara to Los Angeles County. Rainfall amounts around 1 inch are expected, with 2 to 3 inches possible in the favored foothills or anywhere where heavier cells or thunderstorms form. Peak rainfall rates should generally range between 0.25 and 0.50 inches per hour, but isolated rates up to 1.00 inches per hour are possible near heavier cells or thunderstorms. There is a risk for minor to moderate debris flows near recent burn areas, with a very small chance of a damaging debris flow if one of those isolated heavy cells directly hits a burn area. Light rain showers could linger through Thursday. Another system could bring light rain to the area Saturday into Sunday.
