Fire Weather Watch Issued for Thursday Evening to Friday Evening
"Surface high pressure moving into the Great Basin will bring areas of strong gusty winds Thursday night and Friday . . . especially through and below passes and canyons," the National Weather Service advised Tuesday afternoon.
"This will be combined with very low humidity to bring a high fire danger for the mountains . . . valleys and Orange County. Conditions will gradually improve Friday night as winds diminish."
Daytime highs for Thursday and Friday are expected in the 70s and high 60s, according to the Weather Service.
The watch area includes the valleys of Riverside and San Bernardino counties, and the mountains on both sides of the San Gorgonio Pass, including the Mountain Top, Front Country and San Jacinto ranger districts of the San Bernardino National Forest.
"A fire weather watch means that critical fire weather conditions are forecast to occur," the Weather Service advised.
Northeast winds of 25 miles per hour with gusts of 35 to 45 mph will be possible in some areas. Red flag warnings may be issued later this week.
