Los Angeles ? Rain-soaked California got even wetter Monday as another storm dumped heavy snow in the mountains, eroded beaches and shut down a 40-mile stretch of the state’s major north-south highway.

Flooded roads turned Southern California’s morning commute into a white-knuckle obstacle course, while mountain snow left the peaks above Los Angeles capped with white.

Trucks are stopped due to heavy snow on Interstate 5, the primary north-south route across California, near Gorman, Calif. Heavy snow Monday shut down the major highway north of Los Angeles and slowed post-holiday travel in the Sierra Nevada as Californians grappled with a second week of stormy weather.

About 2 feet of snow fell in the Tejon Pass north of Los Angeles, stranding some drivers and shutting down a section of Interstate 5. It was not clear when the pass would reopen.

One man died in the San Fernando Valley when his car went off a road and slammed into a palm tree. Another man was killed in Pomona when he tried to run across the San Bernardino Freeway and was struck by two vehicles.

California has been battered over the past week by severe storms that caused widespread street flooding. More storms are expected later in the week.

The storms have been caused by an extensive low pressure system that edged down from the Gulf of Alaska and remained parked off the Pacific Northwest coast. The latest front was expected to linger through today in Southern California before another system moves over the state later this week.

In Nevada, crews struggled for a fourth day to clear roads after a powerful storm dumped up to 4 feet of snow in some areas around Reno. “We’re making progress,” city spokesman Steve Frady said, calling it the community’s heaviest snowfall in 15 years.

Rain and snow also dampened Arizona on Monday for the second time in five days, prompting officials in Sedona to plan for possible voluntary evacuations if Oak Creek rose out of its banks.
