Update, Saturday, 10:20 a.m.
One northbound lane of Highway 101 near Ventura has been reopened.
Highway 166 is now fully reopened after flooding caused its closure Friday.
All lanes of northbound Highway 101 in northern Ventura County at Highway 33 were closed indefinitely Friday afternoon because of roadway flooding and mudslides, officials said.
“Approximately 2 to 3 feet of standing mud is blocking the northbound side of U.S. 101,” said Officer Jonathan Gutierrez of the California Highway Patrol.
Caltrans crews were on scene clearing the freeway through the La Conchita area, and all northbound traffic was being diverted at Sea Cliff and directed southbound.
“There is no estimated time for reopening,” Gutierrez said.
Farther north on the Santa Barbara County/San Luis Obispo County line, Highway 166 from Highway 101 south of Nipomo to Interstate 5 near Bakersfield was closed because of flooding.

Refugio Canyon in the Sherpa Fire burn area was reported to be impassable, with the creek coming across the road in several locations.
