There were no immediate reports of serious injuries after a tractor trailer flipped on U.S. Highway 395 near Pearsonville, about 150 miles north of Los Angeles.
Highway 6 was shut down for a few hours Monday afternoon due to downed power lines south of Yosemite National Park near Bishop, California, where winds gusted up to 58 mph.
A wind gust of 94 mph was reported further north Monday morning at Mammoth Lakes Airport, where several vehicles were reportedly damaged by the howling winds, including some in which windows were shattered by flying debris.
The shift in conditions is a preview of a major change in the weather across California that's expected to bring rain and snow for Thanksgiving.
