Winds have calmed since yesterday, and are now gusting in the 15-25 mph range at higher elevations. Despite the wind improvement, this prolonged heat wave will continue to bring very low RH that will cure and dry the fuels. ERC values are exceeding or approaching the max moving average for a number of regions. Conditions are dangerous, and we urge extreme caution. 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 FOR THE INTERSTATE 5 CORRIDOR, VENTURA MOUNTAINS, AND SOUTHERN AND CENTRAL SANTA BARBARA COUNTIES... ...FIRE WEATHER WATCH IN EFFECT ON FRIDAY FOR INTERIOR SAN LUIS OBISPO COUNTY AND CUYAMA VALLEY... ...WIDESPREAD ELEVATED FIRE WEATHER CONDITIONS ELSEWHERE ACROSS VALLEYS AND MOUNTAINS THROUGH MUCH OF NEXT WEEK, MOST SIGNIFICANT FRIDAY AND SATURDAY... Temperatures will continue to climb each day through the week as humidities fall and dry air expands. Friday and Saturday are especially extreme as onshore flow weakens, high pressure aloft peaks, and the marine layer possibly erodes away or drastically shrinks. Over the mountains and interior valleys, high temperatures will climb to 108 to 118 by Friday with all time records threatened. Minimum humidities will fall to 5 to 10 percent by Friday. Over the coastal valleys, high temperatures will climb to 100 to 110 by Friday. Minimum humidities will fall to 12 to 20 percent. Coastal areas will also warm and dry significantly, but exactly how the marine layer behaves will drive the magnitude. There is more clarity on southern Santa Barbara County however as moderate Sundowner winds will clear the marine layer and allow temperatures to rise into the 90 to 100 degree range on Friday with minimum humidities falling to 12 to 25 percent...especially in the foothills. Overnight lows between 75 and 85 will be common in the mountains, foothills and deserts with moderately poor humidity recoveries of 25 to 45 percent. Meanwhile, the winds will turn to northwest to northeast later today through Friday, with gusts of 25 to 40 mph likely over Santa Barbara County, many mountains, and the Antelope Valley. While classic Red Flag thresholds will likely not be met, considering the extreme nature of this event and the holiday fire ignition sources available, conditions are favorable for critical fire weather activity and behavior. Less hot conditions are likely for the coastal and adjacent valley areas by Sunday or Monday, but the extremely hot conditions will change little over the at least the mountains and interior through most if not all of next week. This is one of the longest and most extreme heat waves on record for interior areas. Elevated fire weather conditions will continue for the foreseeable future, with a high risk for grass fires and plume dominated wildfires. There is a high risk for heat related illness as well. $$ ECC028-051015- Santa Barbara County excluding Los Padres National Forest- Discussion for Santa Barbara ECC Dispatch 908 AM PDT Thu Jul 4 2024 ...RED FLAG WARNING IN EFFECT FOR THE INTERSTATE 5 CORRIDOR, VENTURA MOUNTAINS, AND SOUTHERN AND CENTRAL SANTA BARBARA COUNTIES... ...FIRE WEATHER WATCH IN EFFECT ON FRIDAY FOR INTERIOR SAN LUIS OBISPO COUNTY AND CUYAMA VALLEY... ...WIDESPREAD ELEVATED FIRE WEATHER CONDITIONS ELSEWHERE ACROSS VALLEYS AND MOUNTAINS THROUGH MUCH OF NEXT WEEK, MOST SIGNIFICANT FRIDAY AND SATURDAY...
