Though the weather calmed on Saturday afternoon, the National Weather Service still had several advisories in effect for San Luis Obispo County through Sunday.
A high-surf advisory is in effect through 4 a.m. Monday from the Monterey County line to Point Conception in Santa Barbara County.
Forecasters warn that a low-pressure system centered over Oregons offshore waters generated seas of over 20 feet Saturday morning.
Those high seas are expected to move toward the Central Coast Saturday night, leading to dangerous surf and rip currents that could especially affect northwest facing shores from Sunday morning through Monday.
Surf is forecast to build from 10 to 13 feet and generate dangerous rip currents along exposed northwest facing shores Sunday morning and persist through Sunday afternoon.
The Weather Service also issued a small-craft advisory in effect through 3 p.m. Sunday from Point Piedras Blancas in northern San Luis Obispo County to Point Arguello and the Channel Islands.
Southwest winds are expected between 20 and 30 knots, with occasional gusts to 35 knots. The winds are forecast to become west and northwest around sunrise on Sunday and persist through the afternoon, according to the Weather Service.
There is also a wind advisory in effect through 6 a.m. Sunday in the interior valleys and mountains of San Luis Obispo County.
Southwest winds are expected between 25 and 50 mph, with gusts of up to 50 mph, according to the Weather Service, creating potentially hazardous driving conditions.
