UPDATE (5:11 p.m.) - Flooding has closed Southbound Highway 101 at Milpas Street in Santa Barbara, according to Caltrans. The northbound lanes of the highway are closed at State Route 150, at Winchester Canyon Road and from Mariposa Reina to Highway 1 north of Gaviota.

Caltrans was also requesting a closure of Highway 166 at Highway 33 or in Maricopa and at Highway 101, according to CHP.

Highway 1 also remains closed north of San Simeon.

Drivers are advised to use I-5 as an alternate route.

UPDATE (4:35 p.m.) - As rain continues to fall steadily across the Central Coast, several local highways or portions of them are closed.

Santa Barbara County Sheriff Bill Brown says a full closure of Highway 154 is in place to due major rockfall.

The northbound lanes of at Mariposa in the Gaviota area are also closed due to what Sheriff Brown describes as significant rockfall, adding that a rock net has fallen out and heavy equipment will need to be brought in to remove it.

That won’t happen Monday, according to the sheriff, who says the closure will likely last through sometime Tuesday.

Highway 192 has several spots with running water coming over the road, Highway 150 is closed due to rockslides and Highway 33 closed at mile marker 12 due to rockslides.

Highway 1 at Black and Solomon roads in the Santa Maria area was also closed.

A closure of the northbound lanes of Highway 101 in Santa Barbara was going to hopefully be removed once a separate closure at Highway 33 was in place.

Officials say they are trying to keep people from coming into the area affected by multiple evacuation orders but let those already in the area head north.

ORIGINAL STORY: The northbound lanes of Highway 101 were being closed along parts of the Central Coast Monday.

The San Luis Obispo County Office of Emergency Services reported the California Highway Patrol was closing the northbound lanes of the highway at Avila Beach Drive outside San Luis Obispo as of 10:15 a.m.

Drivers were being asked to take Price Canyon Road into San Luis Obispo as an alternate route.

In Santa Barbara County, CHP reported the northbound lanes of Highway 101 at Mariposa Reina in the Gaviota area were closed as of 9:50 a.m. The southbound lanes remained open but drivers in the area reported a lot of debris on the highway.

CHP reported the northbound onramp to Highway 1 was also closed in the area.

Due to power outages, Caltrans was unable to activate emergency alert signs in the area warning drivers of the closures.

While the Santa Barbara CHP office is reporting some crashes in its area, the San Luis Obispo area CHP was dealing with dozens of calls related to flooded roads, debris on local roads, crashes, traffic hazards and more when rain started really impacting local roadways around 6 a.m. Monday.
