951 WWUS86 KLOX 100025 RFWLOX URGENT - FIRE WEATHER MESSAGE National Weather Service Los Angeles/Oxnard CA 425 PM PST Thu Jan 9 2025 ...HIGH END RED FLAG WARNINGS IN EFFECT FOR MUCH OF LOS ANGELES AND VENTURA COUNTIES THROUGH 6 PM FRIDAY DUE TO MODERATE TO STRONG SANTA ANA WINDS AND LOW HUMIDITIES... .Critical Red Flag fire weather conditions will continue across much of Los Angeles and Ventura counties through Friday due to moderate to strong Santa Ana winds and low humidities. While winds had diminished some last night, they have increased in strength and areal coverage today, and will continue through early Friday morning. The strongest winds tonight into early Friday morning will be across the mountains (including the Santa Susanas and Santa Monicas) and Santa Clarita Valley, where damaging wind gusts of 55 to 65 mph can be expected, except isolated gusts 65 to 75 mph in the San Gabriels, Santa Susanas, and western Santa Monica mountains. The gusty Santa Ana winds have also overspread many of the typical wind prone coastal and valley areas in LA/Ventura counties, with gusts in the 35 to 55 mph range. With the enhanced upper level wind support through tonight, there will be some breezy conditions across portions of the LA Basin, especially the west side of LA coast and Hollywood Hills. Humidity values between 5 and 15 percent will be common today and Friday across the Red Flag Warning area, with poor overnight recoveries under 20 percent in windy areas tonight. The increased Santa Ana winds today into Friday morning will bring high end Red Flag conditions to the wind prone mountains and valleys of Los Angeles and Ventura counties, as well as the Malibu coast. The offshore winds are expected to diminish on Friday afternoon, with an onshore wind shift likely across many coastal and coastal valley areas. Offshore winds are expected to weaken on Saturday. An extended period of elevated to potentially critical fire weather conditions are in the forecast for Sunday through Wednesday due to moderate to locally strong offshore winds, likely peaking on Tuesday.
