California Highway Patrol officials say westbound Interstate 80 is now cleared after a fatal 16-vehicle crash shut down westbound traffic in the Sierra Nevada, where snow and hail is falling.

CHP spokesman Officer Chris Nave said the crash happened Thursday in Placer County after the weather turned nasty and hail began to fall.

Nave said one man died when his pickup truck crashed into a truck. He said a few other people had minor injuries.

The cause of the crash remained under investigation.

Placer County Sheriff's Office reported the crash just after 12 p.m. Thursday.
