A long heat wave with hot, dry weather today will cause critical fire weather conditions when the afternoon, terrain driven winds pick up. Onshore will offer slight increases in RH over the next few days. However the long period of above average temperatures will continue to dry fire 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 UNTIL 6 AM MONDAY FOR THE INTERSTATE 5 CORRIDOR AND WESTERN ANTELOPE VALLEY FOOTHILLS DUE TO GUSTY 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 NEXT WEEK... Long lasting and extremely hot conditions Will continue through much of next week. For today, very hot temperatures and low humidities are expected across the interior valleys, mountains, and deserts with highs between 105 and 118 degrees (possibly approaching all time record highs in a couple locations), Overnight lows will remain very warm in these areas, with some readings in the mid 70s to near 90 in warmest locations. A light north to northeast wind influence this morning will bring very low humidities of 5 to 10 percent this morning into early afternoon across the interior, with a pronounced onshore wind shift to the south and southwest later this afternoon and evening, except northwest near the I-5 corridor. For the coast and coastal valleys, increasing onshore flow and marine layer influence will bring some cooling and humidity improvement to the coast and most coastal valleys today. Less hot conditions are likely for the coastal and adjacent valley areas Sunday into Monday, but the extremely hot conditions will change little over the mountains and interior through most if not all of next week. Onshore flow will likely continue to increase on Sunday and Monday, which will likely lead to increasing southwest to northwest winds. The interior areas could see widespread wind gusts of 25 to 40 mph Saturday night into Sunday night. The best overlap of gusty northwest winds and low humidities will likely occur in the Interstate 5 corridor and western Antelope Valley foothills, resulting in the extension of the Red Flag Warning for those areas through Sunday night. While other interior areas are not in a Red Flag Warning, it is important to note that elevated to brief critical fire weather conditions will exist through much of next week, with the potential for additional large fires. The extreme heat will generate very deep mixing heights of 10000 to 18000 feet today through much of next week across the interior, increasing the potential for large plume dominated fires, especially in the mountains and foothills. 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. $$ ECC028-071045- Santa Barbara County excluding Los Padres National Forest- Discussion for Santa Barbara ECC Dispatch 933 AM PDT Sat Jul 6 2024 ...RED FLAG WARNING IN EFFECT UNTIL 6 AM MONDAY FOR THE INTERSTATE 5 CORRIDOR AND WESTERN ANTELOPE VALLEY FOOTHILLS DUE TO GUSTY 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 NEXT WEEK...
