In Marin County, winds approached 90 miles per hour on mountain tops and took down trees, power lines and structures.
Trina Baucom, 60, was less than 100 feet from the Point Reyes Lighthouse parking lot when she turned around. Rocks and sand flew across the roadway as her Jeep Wrangler swayed on a narrow road more than 200 feet above the Pacific Ocean.
“It was pretty scary up there,” she yelled over the wind and sideways rain.
On a cattle ranch just east of the lighthouse, William Nunes, 27, watched as the wind ripped a calf hutch from the ground and sent it flying into the air and over a hill.
Next went the roof to his cattle barn. Several sheets of metal as long as two cars were torn off and landed beside dozens of wet cows. The metal sheets shook violently, with the wind threatening to send them flying again, until two ranch workers secured them to the manure-covered ground while Mr. Nunes poured gravel on top to weigh them down.
In San Francisco, one of the most dramatic scenes of the storm unfolded at 18th and Market streets, a half-mile west of the Castro District. A giant pine on a city-owned hill fell in the middle of the morning, causing a small landslide that sent dirt and tree limbs tumbling into the road.
