While the long heat wave continues, the ridge axis has finally moved east of our area and there have been some improvements to fire weather conditions. A deepening marine layer with more steady onshore winds and slightly lower temperatures have caused all Red Flag Warnings to expire as scheduled last night. Conditions will continue to gradually improve through Tuesday. While the critical fire weather has ended, fuel ERCs are still near/exceeding the max moving average and between the 97th and 99th percentile. 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 AM MONDAY FOR THE INTERSTATE 5 CORRIDOR AND WESTERN ANTELOPE VALLEY FOOTHILLS DUE TO GUSTY SOUTHWEST TO NORTHWEST WINDS, HOT TEMPERATURES, AND LOW HUMIDITIES... ...WIDESPREAD ELEVATED TO BRIEF CRITICAL FIRE WEATHER CONDITIONS WITH LARGE PLUME POTENTIAL ACROSS INTERIOR VALLEYS, MOUNTAINS, AND DESERTS THROUGH MUCH OF THIS WEEK... Long lasting and extremely hot conditions Will continue through much of this week across the interior. For today, very hot temperatures and low humidities will continue across the interior valleys, mountains, and deserts with highs between 100 and 115 degrees and minimum humidities between 5 and 15 percent (hottest and driest in the Antelope Valley. Onshore flow will strengthen considerably today into tonight, causing stronger and more widespread onshore winds across the interior, with gusts between 25 and 40 mph common, except isolated gusts to 45 mph in the Antelope Valley foothills this afternoon and evening. These strengthening onshore winds combined with the lingering hot and dry air mass will make fire weather conditions more dangerous today across the interior where widespread elevated to brief critical fire weather conditions exist. The longest duration of gusty winds overlapping with low humidities and hot temperatures will be the Interstate 5 corridor and western Antelope Valley foothills, where a Red Flag Warning remains in effect through tonight. In addition, the hot and unstable conditions will make conditions favorable for large vertical plume growth with any new or existing fires (Lake Fire), as projected mixing heights between 10,000 and 18,000 feet will be common. Conditions remain favorable for large fire growth and extreme fire behavior across the interior, especially in the Red Flag Warning area. For the coasts and coastal valleys, the strengthening onshore flow and marine layer influence will continue to bring a cooling trend with higher humidities today. Very hot conditions will change little over the mountains, interior valleys, and deserts through most if not all of this week, resulting in a continuation of elevated to brief critical fire weather conditions. As the marine layer becomes more shallow Tuesday through Thursday, there is the potential for a warming and drying trend for the coasts and valleys. In addition, there is the potential for some gusty sundowner winds with lower humidities across portions of southern Santa Barbara county during the late afternoon through nighttime hours from Tuesday through Thursday. This is one of the longest and most extreme heat waves on record for interior areas. For the foreseeable future, there will be a higher risk for large fires and plume dominated fires across the interior. There is a high risk for heat related illness as well. $$ ECC028-081045- Santa Barbara County excluding Los Padres National Forest- Discussion for Santa Barbara ECC Dispatch 940 AM PDT Sun Jul 7 2024 ...RED FLAG WARNING IN EFFECT UNTIL 6 AM MONDAY FOR THE INTERSTATE 5 CORRIDOR AND WESTERN ANTELOPE VALLEY FOOTHILLS DUE TO GUSTY SOUTHWEST TO NORTHWEST WINDS, HOT TEMPERATURES, AND LOW HUMIDITIES... ...WIDESPREAD ELEVATED TO BRIEF CRITICAL FIRE WEATHER CONDITIONS WITH LARGE PLUME POTENTIAL ACROSS INTERIOR VALLEYS, MOUNTAINS, AND DESERTS THROUGH MUCH OF THIS WEEK...
