Brief Description |
Red Flag Warning |
Detailed Description |
RED FLAG WARNING IN EFFECT THROUGH SATURDAY EVENING FOR ALL MOUNTAINS, ANTELOPE VALLEY AND ADJACENT FOOTHILLS, AS WELL AS SOUTHERN SANTA BARBARA COUNTY FOR EXTREMELY HOT AND DRY CONDITIONS, LOCALLY GUSTY WINDS AND POTENTIAL DRY LIGHTNING. .The extreme heat wave will continue through Monday, but peak through Saturday, with high temperatures between 105 and 115 over most mountain, desert and foothills areas and minimal overnight recoveries. Locally gusty winds will form as well, strongest over southern Santa Barbara County with Sundowner gusts between 25 and 45 mph each night. There will be increasing instability on Saturday, leading to deep mixing heights up to 18,000 feet, which will also lead to a high risk for erratic plume-dominated fire behavior, especially in the mountains, foothills, and deserts. While standard Red Flag Warning criteria is unlikely, there is a history of large fires during similar weather conditions. As a result, Red Flag Warnings will remain in place for all mountain and foothill areas through Saturday, with the areas of highest concerns being those with the stronger winds like southern Santa Barbara County. In addition, the Red Flag Warning has been expanded to include the Antelope Valley and eastern foothills on Saturday afternoon and evening due to the increased threat of dry lightning and strong outflow winds combined with the extrema heat and low humidities. In addition, there is an increasing threat for dry lightning and gusty downburst winds this weekend, which will increase the fire danger risk. The Red Flag Warning has been expanded to include the Antelope Valley and eastern foothills on Saturday afternoon and evening due to the increased threat of dry lightning and strong outflow winds combined with the extrema heat and low humidities in those areas. * WINDS. West to north winds 10 to 15 mph with gusts up to 30 mph. Gusty and erratic winds possible with any new fires or thunderstorms. * RELATIVE HUMIDITY. Minimums 8 to 15 percent. Poor overnight recoveries of 15 to 30 percent. * TEMPERATURES. Maximums between 100 and 110 common for lower elevations, with minimums between 82 and 92. Isolated highs near 115 possible. * THUNDERSTORMS. There is an increasing risk for dry lightning over Los Angeles and Ventura Counties this weekend, which can start new fires, spread them rapidly with gusty downburst winds, and provide little if any extinguishing rain. * IMPACTS. If fire ignition occurs, conditions are favorable for rapid fire spread and extreme fire behavior which would threaten life and property. |
