Dry conditions with light afternoon breezes continue through Tuesday. Then, an impactful storm system brings widespread wetting rains and breezy winds to the district starting Tuesday night into Thursday. Wind gusts on Wednesday could reach 35 to 40 miles per hour on the ridgelines and at the immediate coast. Additional rainstorms are expected Friday into the upcoming weekend. Note : All winds are 20-foot Winds Unless otherwise specified. Thunderstorms imply strong, gusty and erratic winds. ...Discussion from Los Angeles/Oxnard... ...PERIODS OF RAIN AND MOUNTAIN SNOW TUESDAY THROUGH THURSDAY... ...POSSIBLE HEAVY RAIN AND THUNDERSTORMS LATE WEDNESDAY AFTERNOON INTO EARLY THURSDAY BRINGING THREAT OF DEBRIS FLOWS IN RECENT BURN SCARS... Dry weather today, then a cold upper level low pressure system will likely bring some rain to areas south of Point Conception on Tuesday, especially in Los Angeles county where there will also be a 5-10 percent chance of thunderstorms. Most areas are expected to see less than 0.50 inches of rain, however there could be isolated higher amounts near heavier showers or thunderstorms. Peak rainfall rates could be up to 0.33 inches per hour across Los Angeles County. Due to the fast moving nature of these storms, 0.33 inches may occur in time frames as little as 15 to 30 minutes. A stronger storm system is then expected to impact the region Wednesday into Thursday. On Wednesday, there will likely be light to moderate pre-frontal rainfall, heaviest in orographically favored coastal slopes and foothills. A fast moving cold front will then sweep across the region on Wednesday night, brining the potential for 3 to 4 hours of moderate to heavy rainfall. Behind the front, there will be cold and unstable air that will bring the threat of heavy showers and a slight chance of thunderstorms into Thursday morning. Storm totals for Wednesday into Thursday are expected to range from 1 to 2 inches for coasts and valleys, and 2 to 4 inches for foothills and mountains. Peak rainfall rates are most likely expected to impact the region on Wednesday night, and could exceed 0.50 inches per hour. As a result, there is a 30-50 percent chance of shallow debris flows for the recent burn scars, with a 10-30 percent chance of a more significant warning level debris flow. In addition, there will likely be significant snow across the local mountains for the Wednesday into Thursday storm system, with 1 to 2 feet of snow likely for elevations above 6000 feet. Snow levels are expected to lower rapidly late Wednesday night into Thursday morning , falling as low as 3000 feet. As a result, there is the potential for accumulating snow and ice on low elevation passes such as Interstate 5 near the Grapevine, Highway 14 from Agua Dulce to Palmdale, Highway 33 north of Ojai, and upper portions of Highway 154 through Santa Barbara County. $$ ECC028-111045- Santa Barbara County excluding Los Padres National Forest- Discussion for Santa Barbara ECC Dispatch 934 AM PDT Mon Mar 10 2025 ...PERIODS OF RAIN AND MOUNTAIN SNOW TUESDAY THROUGH THURSDAY... ...POSSIBLE HEAVY RAIN AND THUNDERSTORMS LATE WEDNESDAY AFTERNOON INTO EARLY THURSDAY BRINGING THREAT OF DEBRIS FLOWS IN RECENT BURN SCARS...
