Jurica said, by 10:40 a.m. on Monday, gusts of up to 60 mph in portions of Santa Clarita Valley, channeling down into Ventura County, western Los Angeles County, moving over into the San Gabriel and San Bernardino County Mountains.”Like what we saw a couple of weeks ago, winds do create more speed as they move down slop and those down slopping winds we are going to have to really watch for,” Jurica added.
Fire Weather WatchGusty offshore winds and very low humidity will continue later Tuesday night through Thursday in these same areas. The strongest winds during this period are expected to be Wednesday night into Thursday morning with gusts in the 40 to 55 mph range. Due to the potential for continue Red Flag conditions, a Fire Weather watch has also been issued for most of these areas from late Tuesday evening through Thursday evening.High Wind WatchesIn addition, High Wind Watches will be in effect late Monday afternoon through Tuesday morning for Ventura and parts of Los Angeles counties due to a “high risk of widespread damaging winds,” according to the NWS. By Friday, an upper low may bring a chance of light rain and mountain snow, along with cooler temperatures. Moderate to strong gusts could cause downed trees, power outages and dangerous sea conditions.
