National Weather Service warns of thunderstorms, tornadoes

The National Weather Service issued a special weather statement Saturday warning about thunderstorms and possible waterspouts that could even come ashore as weak tornadoes during the storm.

The system was expected to produce wind gusts up to 50 mph, pea-size hail, brief heavy downpours and cloud-to-ground lightning, the Weather Service said.

“Some rotation is being detected offshore, with a slight chance of these storms spinning up a brief tornado over the statement area,” the Weather Service added.

The advisory was for western San Luis Obispo and Santa Barbara counties — from Point Conception to Cambria — and was in effect until 4:15 p.m. Saturday.

The Weather service warned that the hail could cause minor damage to outdoor objects is possible and gusty winds could knock down tree limbs and blow around unsecured objects.

Meanwhile, the National Weather Service issued a flood watch and a high surf advisory for San Luis Obispo County on Saturday morning.

The flood watch was sent out for the entirety of SLO County and would be in effect until Sunday at 6 p.m.

The agency also issued a high surf advisory for all SLO County beaches until 6 a.m. Sunday.

Highway 1 reopens after minor mudslide closure, new closure begins

Late Friday night, Caltrans extended the closure of Highway 1 in Big Sur as far south as Ragged Point due to a new mudslide at Alder Creek.

By Saturday morning, crews had cleared the road and reopened access as far north as Limekiln State Park at the southern end of the ongoing 12-mile closure around Paul’s Slide and the Dolan Point Slide, which have prevented full access to the scenic coastline for more than a year.

But the drama wasn’t over for the scene highway.

Later Saturday night, a piece of Highway 1 north of the existing Paul’s Slide and Dolan Point Slide closure crumbled away amid the onslaught of heavy rain, according to Caltrans.

Highway 1 was closed at Palo Colorado due to a slip-out near Rocky Creek on Saturday night, Caltrans said.

“The southbound lanes have been lost and northbound lanes potentially impacted,” Caltrans said.

The agency was expected to assess conditions of the road on Sunday.

The current closure now extends south to Limekiln, the agency said.

What’s ahead in SLO County’s forecast

As the storm passes, the National Weather Service predicted a light chance of rain and clear skies going into the first week of April.

The risk of flooding and hail will be low, while temperatures were expected to range from a low of 46 to a high of 73, according to the agency’s forecast discussion. .

Cool temperatures will continue through Monday, the agency said, before a warming trend heats things up later in the week.

Another round of “cool and unsettled weather” could return next weekend, however.
