Gusting winds were responsible for a downed power line in northwest Banning, leaving about 200 homes without power Friday afternoon, a city yard spokeswoman said. Workers expected to have power restored to all homes by sundown.

A high-wind advisory was in effect for the Pass area, from Highway 62 to Yucaipa, urging drivers of high-profile vehicles and trailers to exercise caution, California Highway Patrol officials in Banning said.

The National Weather Service estimated that the winds in the San Gorgonio Pass gusted up to 60 mph Friday.

Throughout San Bernardino and Riverside counties, 36,000 customers were without power after the winds picked up in the morning, Southern California Edison spokesman Steve Conroy said.

Some people saw flickering lights or had their power out for about an hour, Conroy said.

"All wind-related," he said.

According to the The National Weather Service, northeast winds of 30 mph to 40 mph are expected to continue today with gusts up to 70 mph in canyons and passes. The winds are expected to decrease by this afternoon.

California Highway Patrol issued a blanket wind advisory Friday morning throughout Riverside and San Bernardino counties that extended into the night.

In Rancho Cucamonga, winds are believed to have contributed to a tractor-trailer overturning on the westbound Interstate 210 to the southbound I-15 transition road, CHP officials said. The crash left the road shut down, and CHP officials were waiting for the winds to die down before uprighting the truck.
