LOS ANGELES—Heavy rain poured on the Southland overnight Dec. 29, prompting mudslides, debris flows, and flooding that made for a messy morning drive that was fortunately light due to the approaching holiday weekend.
Snowfall forced the closure of Interstate 5 through the Grapevine early Thursday morning in northern Los Angeles County, while a mudslide blocked traffic and trapped some vehicles on Coldwater Canyon Avenue in Studio City, and flooding blocked the westbound Santa Monica (10) Freeway near the McClure Tunnel in Santa Monica.
