Strong, cold and damaging Santa Ana winds are blowing through Southern California Friday into Saturday, the National Weather Service reported.
The strongest winds are likely to occur all day Friday and into Friday night, according to the agency. A high wind warning and a wind advisory are in effect until 2 p.m. Saturday.
By Friday afternoon, the strongest gust was 70 mph in Fremont Canyon in the Santa Ana Mountains, according to the weather service. A gust of 67 mph was recorded in Chilao, in the Angeles National Forest, and a 64 mph wind swept through the Malibu Hills.
A windblown dust and ash advisory was issued Friday through Saturday by the South Coast Air Quality Management District. Windblown ash is expected downwind of recent wildfire burn areas, including the Sand Fire in Santa Clarita, the Blue Cut Fire in the Cajon Pass, and the Reservoir and Fish Fire areas above Azusa and Duarte.
In areas where ash and dust are blowing, everyone should avoid outdoor vigorous activity as well as indoor exertion, AQMD said.
Cold temperatures are expected during the wind event, but warmer conditions are in the forecast starting Saturday afternoon.
Wind gusts between 60 to 80 mph are expected in the Ventura County mountains, while coastal valleys will see gusts between 40 and 60 mph.
A red flag warning is also in effect into Saturday as humidity levels decrease, according to the weather service. The combination of low humidity and strong winds will bring extreme fire danger to the reason, especially when associated with downed power lines.
Strong winds also bring the threat of downed trees, power outages and hazardous driving conditions.
