Mark’s Thursday Forecast: high fire danger and Santa Ana Winds 10/24/19
SAN DIEGO (KUSI) – With unseasonable heat and strong Santa Ana winds expected in the San Diego area through the end of the workweek, local firefighting crews were on high alert.
To alert the public to the combustion hazards posed by the hot and windy conditions, the National Weather Service issued a red flag warning, in effect until 5 p.m. Friday in the mountains and valleys. During the period, sustained winds of 25 to 35 mph were expected, with gusts up to 65 mph near mountain ridge tops.
The fiercest winds are likely to hit late Thursday evening and early Friday, the NWS advised.
Daytime humidity levels, meanwhile, could drop as low as 5%, and high temperatures in some inland areas will hover in the mid- to high 90s.
The weather service also issued a high-wind warning that will be in effect in the county mountains and valleys from 8 Thursday evening until 2 p.m. Friday. Officials warned that the stiff winds could blow down trees and power lines, and might make driving dicey in some locales, particularly for those in RVs, tractor-trailers and other high-profile vehicles.
The strong winds will continue through Friday afternoon, then begin subsiding, forecasters said.
