Traffic is flowing again on a major Southern California traffic artery that was severed for the second time in three days because of ice and snow from a winter storm that brought very unseasonable freezing temperatures to much of the state.

The California Highway Patrol says the Grapevine segment of Interstate 5 was reopened at 7:25 a.m. Saturday, about four hours after icy conditions forced the closure.

Californians are bundling up with sweaters and gloves as they deal with morning temps that fell into the 20s and 30s in many areas, and much lower in the mountains.

The National Weather Service says records could fall as the cold snap stretches into early Sunday.

Citrus growers broke out wind machines and took other steps to protect crops from freezing.
