A high wind advisory will be in force until 3 p.m. Tuesday in the San Gabriel Mountains and a fire weather watch will be in force from Tuesday evening through Wednesday in mountain and forest areas of L.A. and Ventura counties.
The strongest winds Tuesday will blow through the Interstate 5 corridor, the National Weather Service said in a statement, forecasting north winds of 20 to 30 miles per hour with 50-mile-per-hour gusts.
“Gusty winds will make driving difficult, especially for high profile vehicles,” according to the statement, which warned that that Highway 33 in Ventura County would be difficult to negotiate, along with Interstate 5 and the Antelope Valley (14) Freeway in Los Angeles County.
Also scheduled is a fire weather watch from Tuesday evening through Wednesday in the San Gabriel Mountains and the forest areas that cover them — the Angeles National Forest in L.A. County and Ventura County’s Los Padres National Forest. It was issued because of an expectation of gusty Santa Ana winds blowing at between 35 and 45 mph and low humidity in the San Gabriel Mountains and most L.A. and Ventura county valleys.
“The Santa Ana winds will bring warming and drying to the watch area, with widespread humidities between 8 and 20 percent, along with temperatures climbing well into the 80s across lower elevations,” warned an NWS statement. “Coastal areas of Los Angeles and Ventura counties will see elevated fire weather conditions, and perhaps a few hours of critical conditions.”
“If fire ignition occurs, conditions may be favorable for rapid fire spread and extreme fire behavior, which would threaten life and property.”
A Fire Weather Watch means that critical fire weather conditions are possible, according to the NWS.
