Brief Description |
Red Flag Warning |
Detailed Description |
RED FLAG WARNING IN EFFECT THROUGH 10 PM THIS EVENING FOR SAN LUIS OBISPO COUNTY MOUNTAINS (INCLUDING THE SANTA LUCIA RANGE), SANTA MONICA MOUNTAINS, AND EASTERN SANTA YNEZ RANGE AND ADJACENT SOUTHEAST COAST OF SANTA BARBARA COUNTY DUE TO EXTREMELY HOT AND DRY CONDITIONS, LOCALLY GUSTY WINDS. . RED FLAG WARNING EXTENDED UNTIL 10 PM SUNDAY FOR THE INTERIOR MOUNTAINS OF LOS ANGELES, VENTURA, AND SANTA BARBARA COUNTIES (INCLUDING THE SANTA SUSANA MOUNTAINS), ANTELOPE VALLEY, AND WESTERN SANTA YNEZ RANGE AND ADJACENT SOUTHWEST COAST OF SANTA BARBARA COUNTY DUE TO HOT AND DRY CONDITIONS, LOCALLY GUSTY WINDS, AND POTENTIAL DRY LIGHTNING. .A long duration heat wave will continue away from the immediate coast, with only minor and slow improvement through Monday. Near record high temperatures will continue this weekend with highs between 105 and 115 common over the valleys, lower mountains, and deserts, and 95 to 105 over the inland coastal plain. Very warm temperatures will persist at night across the mountains and foothills. Locally gusty winds will form as well, strongest over southern Santa Barbara County with Sundowner gusts between 25 and 40 mph each night through Monday. There will be increasing instability today and Sunday, 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. There is a threat of thunderstorms this weekend as mid level monsoonal moisture and instability move into the region. The best chance of storms will be across the mountains of Los Angeles and Ventura counties, as well as the Antelope Valley through Sunday. Any storms that develop today and Sunday will have the potential for dry lightning strikes and strong/erratic downburst winds, with localized gusts to 50 mph possible. Due to the significant threat of large plume dominated fires and the risk of dry lightning and additional sundowner winds, the Red Flag Warning has been extended into Sunday evening for portions of the warning area. * WINDS. North 15 to 30 mph with gusts up to 45 mph, strongest at night. Gusty and erratic winds possible with any new fires. * RELATIVE HUMIDITY. Minimums 8 to 18 percent inland of the beaches. Poor to minimal overnight recoveries of 12 to 25 percent in the foothills and mountains. * TEMPERATURES. Maximums between 98 and 108 common in the foothills and mountains, with minimums between 80 and 90. * IMPACTS. If fire ignition occurs, conditions are favorable for rapid fire spread and extreme fire behavior which would threaten life and property. |
