Fire weather concerns remain across the district through early Tuesday thanks to breezy to gusty northerly flow and low relative humidity. Areas of greatest concern remain over the North and East Bay, especially higher elevations. Fire weather conditions gradually improve midweek with returning onshore flow and higher humidity. A warming and drying trend expect late in the week and next weekend. Note : All winds are 20-foot Winds Unless otherwise specified. Thunderstorms imply strong, gusty and erratic winds. ...Discussion from Los Angeles/Oxnard... ......RED FLAG WARNING IN EFFECT UNTIL 6 PM PDT TUESDAY FOR GUSTY NORTHWEST TO NORTHEAST WINDS AND LOW RELATIVE HUMIDITY FOR THE INTERSTATE 5 CORRIDOR AND VENTURA COUNTY MOUNTAINS... ...RED FLAG WARNING IN EFFECT FROM MIDNIGHT TONIGHT UNTIL 6 PM PDT TUESDAY FOR GUSTY NORTH TO NORTHEAST WINDS AND LOW RELATIVE HUMIDITY FOR THE WESTERN SAN GABRIEL MOUNTAINS... ...ELEVATED TO BRIEF CRITICAL FIRE WEATHER CONDITIONS THROUGH TUESDAY FOR REMAINING INTERIOR AREAS AND SOUTHERN SANTA BARBARA COUNTY DUE TO GUSTY WINDS WITH WARM AND DRY CONDITIONS... Strong northwest to north winds will remain widespread across interior Southwest California through this evening. Winds will shift to the north and northeast overnight into Tuesday morning, ushering in much drier air. For today and tonight, many interior areas and southwest Santa Barbara county will see wind gusts between 30 and 50 mph, with isolated gusts as high as 60 mph tonight across the favored ridgetops in the I-5 corridor. When the winds shift to the northeast late tonight into Tuesday morning, wind gusts between 35 and 45 mph will be common across the mountains of eastern Ventura county and Los Angeles county, including the Post Fire. Locally higher gusts up to 55 mph can be expected for the western San Gabriels during this time. Minimum humidities today are expected to generally range between 15 and 25 percent across the interior (including the Post Fire), but are expected to fall to between 5 and 10 percent across many interior areas on Tuesday. With the influx of north to northeast winds and lower humidities, the Red Flag Warning has been extended until 6 pm Tuesday for the Interstate 5 corridor and Ventura County mountains. In addition, the Red Flag Warning has been extended to include the western San Gabriel mountains, valid from midnight tonight through 6 pm Tuesday. Remaining interior areas and southwest Santa Barbara county will see elevated to brief critical fire weather conditions through Tuesday. A strong catalina eddy circulation has brought extensive marine layer clouds across the LA basin today. The northeast winds will likely scour out some of the marine layer influence, mainly over typical offshore wind prone areas such as the Santa Clarita Valley, eastern Ventura county valleys, and possibly the western Santa Monica mountains. Areas that do see the northeast winds briefly surface on Tuesday morning will likely see a rapid drop of humidities into single digits, potentially bringing brief critical fire weather conditions. There is an increased risk for fast-growing grass fires over much of the area, that could transition into wildfires where the fuel beds are most abundant and dry. There will be a return of stronger onshore flow on Wednesday and Thursday, but warm and dry conditions will remain across the interior. $$ ECC028-181630- Santa Barbara County excluding Los Padres National Forest- Discussion for Santa Barbara ECC Dispatch 324 PM PDT Mon Jun 17 2024 ......RED FLAG WARNING IN EFFECT UNTIL 6 PM PDT TUESDAY FOR GUSTY NORTHWEST TO NORTHEAST WINDS AND LOW RELATIVE HUMIDITY FOR THE INTERSTATE 5 CORRIDOR AND VENTURA COUNTY MOUNTAINS... ...RED FLAG WARNING IN EFFECT FROM MIDNIGHT TONIGHT UNTIL 6 PM PDT TUESDAY FOR GUSTY NORTH TO NORTHEAST WINDS AND LOW RELATIVE HUMIDITY FOR THE WESTERN SAN GABRIEL MOUNTAINS... ...ELEVATED TO BRIEF CRITICAL FIRE WEATHER CONDITIONS THROUGH TUESDAY FOR REMAINING INTERIOR AREAS AND SOUTHERN SANTA BARBARA COUNTY DUE TO GUSTY WINDS WITH WARM AND DRY CONDITIONS...
