Caltrans will close Highway 1 on the Big Sur Coast, between Ragged Point in San Luis Obispo County and Deetjen's Big Sur Inn in Monterey County, at 8 p.m. Sunday.
The closure is expected to remain in effect until Tuesday, when the transit agency will assess the conditions.
The closure comes as an atmospheric river dumps rain in the area and is expected to last most of the week. Officials issued evacuation warnings around the Dolan Fire burn scar at 5 p.m. Sunday, as mudslides and downed trees and power lines are possible.
