SAN FRANCISCO (AP) — Here is the latest on the storm hitting California gathered by AP reporters across the state:

Rains have begun falling on parts of Los Angeles. Light showers were felt in the Mission Hills and Reseda sections of the San Fernando Valley a few hours before much heavier rainfall was expected.
9:20 p.m. PST
State transportation officials say heavy rains washed out a portion of the southbound lane of Highway 1 in Marin County.
The San Francisco Chronicle reports the washout forced closure of the southbound lane of Highway 1 between Panoramic and Muir Woods Road in Muir Beach.

While much of California gets soaked, parts of the Central Valley are getting doused with dust.
Forecaster Dan Harty of the National Weather Service says that gusts ahead of an advancing rain storm hit over 40 mph Thursday in places such as Merced and Bakersfield.

Harty says the storms should move into the Central Valley late Thursday and drop rain throughout the night.
5:07 p.m. PST
The city of Glendora has called for the mandatory evacuation of homes near the Colby Fire burn area because of fears that the approaching storm could cause mudslides.
The city on the foothills of the San Gabriel Mountains east of Los Angeles announced it would raise its alert level from orange to red starting at 10 p.m. Thursday. The move shifts evacuations from a suggestion to an order.
The Colby Fire burned 1,900 acres on the steep slopes above the cities of Glendora and Azusa in mid-January.
4:34 p.m. PST

The approaching storm has delayed the launch of a U.S. defense satellite on the central coast.
An Atlas V rocket carrying a classified payload for the National Reconnaissance Office had been scheduled to lift off Thursday from Vandenberg Air Force Base.
However, the launch was postponed to Friday night because of concerns that the storm might bring rain, heavy clouds, gusty winds and even lightning.
2:43 p.m. PST
Los Angeles should expect rain by the end of the day. Already, one apartment complex in a spot prone to mudslides in Riverside was evacuated. In the San Bernardino National Forest, lumber workers were loading concrete weights onto the stacks to keep them from blowing away, and piling sandbags in front of their shop doors to stave off floodwater.

Authorities in Southern Oregon say high wind toppled a tree and killed a homeless man sleeping in a tent along the Pacific Crest Trail.

In Santa Cruz, about an hour south of San Francisco, an elementary school student was trapped for about 15 minutes when an 80 foot tree fell on him, pinning his arm and shoulder until rescuers with chain saws freed him. He was taken to a hospital in good condition but likely a fractured arm.
