Strong, gusty winds continued to bluster through San Diego County’s mountains and deserts Saturday, as a trough of low pressure moves inland over the central portion of the state.

Gusts of 40 miles per hour were recorded on Interstate 8 at the rocky canyons of the Mountain Springs Grade, just east of Jacumba. Gusts of 37 mph were observed in Borrego Springs, and winds hit 31 mph at In-Ko-Pah, also along Interstate 8, according to National Weather Service Mesonet observations.

Winds of 15 to 30 miles per hour, with gusts that could reach 50 mph, prompted the weather service to issue a wind advisory for the mountains and deserts, which was to remain in effect until 4 a.m. Sunday.

“Strong onshore gradients and gusty west to southwest winds will continue across Southern California through tonight, as an upper level low slowly shifts inland across the state through Sunday,” according to the advisory.

Forecasters said the gusty winds would continue to affect areas along mountain ridges, desert slopes and into adjacent deserts and through and below canyons and passes. Motorists on Interstate 8 in the mountains could also be impacted.

The winds could kick up dust in the deserts, which may make for difficult driving conditions and lowered visibility, weather service forecasters said. Drivers, especially those in high profile vehicles, were advised to keep an eye out for broken tree limbs and to use extra caution.

Forecasters said the winds were expected to weaken late tonight, but a secondary, weaker peak could occur Sunday afternoon and evening.
