LOS ANGELES -- High winds across Southern California forced a commuter train line to shut down and knocked a tree onto a car, but no serious injuries are reported.

Wind flipped a canopy out of a yard and onto power lines Wednesday near the Gold Line train tracks in Highland Park.

The incident forced MTA officials to shut down service in both directions until the power lines are repaired.

MTA spokesman Luis Inzunza says the Gold Line light rail track was reopened shortly after 4 p.m. when lines were repaired.

The Gold Line runs from downtown L.A. to Pasadena.

In San Diego County, wind toppled a tree onto a car in San Marcos but the couple inside escaped serious injury.

The National Weather Service says there's a chance of 50 mph gusts through Thursday morning in Los Angeles and Ventura counties.

Fire danger warnings are up in some areas.

Overnight, fierce winds toppling trees, downed powerlines and left 40,000 homes and businesses without power in the Los Angeles area.

At LAX, strong winds forced one arriving flight to be diverted to another airport Tuesday evening, said Allen Kenitzer, spokesman for the Federal Aviation Administration.

The winds, which at the time were gusting up to 35 knots, forced two other flights to use "missed approach" procedures, meaning each had to make two attempts to land, he said. Both flights landed safely.

Strong winds knocked down a large sign at a Jack in the Box restaurant located at Sherman Way and Coldwater Canyon in North Hollywood.

A pickup truck was crushed by a fallen tree in the 7100 block of East Peabody Street in Long Beach. No one was inside the vehicle when the tree fell.

In South Los Angeles, a large tree crashed through the roof of Pilgrim Community Church at 4919 Wadsworth Ave., one block west of Central Avenue.. No one was inside the church at the time. The 90-foot pine tree also damaged two homes when it fell.

Dust and ash from the 250-square-mile Station Fire burn area in the Angeles National Forest blew around and darkened the sky over the foothill suburbs of Los Angeles. The San Gabriel Valley could also get blowing ash from the burn area.
