Among the peak wind gusts recorded over a 24-hour hour period ending around 6 a.m. were 63 miles per hour at Mount Laguna, 55 mph near Julian, 52 mph in Harrison Park, 49 mph near Borrego Springs, 48 mph in Ocotillo Wells and 45 mph in Ranchita, according to the National Weather Service.
A high-wind warning gave way to a less severe wind advisory at 5 a.m. Winds of 25 to 35 mph with gusts to 55 mph could be possible until the advisory expires 11 a.m. Saturday.
"A low pressure system moving from the Great Basin to the southern Rockies will bring periods of gusty northwest to north winds today, and north to northeast winds tonight into Saturday,'' according to the weather service.
The winds may still be strong enough to kick up sand and dust alongside desert roadways, which could make for hazardous driving conditions on portions of Interstate 8, state Routes 78 and 79, and county highways S-2 and S-22, forecasters said. Motorists, especially those in high profile vehicles, were urged to use extra caution.
