The National Weather Service on Sunday evening has issued three warnings to take effect along the Central Coast into Monday and Tuesday.
In a wind advisory in effect from 1 to 10 p.m. Monday, forecasters warn of increasing winds on Monday thanks to a quick-hitting cold storm system expected to move along the coast.
That storm is expected to bring strong gusty winds along the coast and in coastal valleys, west to northwest and 15-25 mph, with gusts to 25 mph.
This could make driving tougher, especially for high-profile vehicles such as trucks and RVs.
The agency has also issued a coastal hazard message for the coast of San Luis Obispo and Santa Barbara counties effective through 7 a.m. Tuesday.
Forecasters warn of hazardous surf and swells between Monday and Tuesday because of a building locally wind-driven swell over costal waters, including the possibility of rip currents.
The highest surf and swell is expected mainly at west and northwest-facing beaches between Monday and Tuesday mornings. Occasional sets above 10 feet are expected.
The agency warns inexperienced swimmers and surfers to stay out of the water during these conditions. A high tide around three feet is forecast between 1:30 and 2:30 p.m. Monday, followed by a low tide around two feet around 6:30 p.m.
For boaters, the agency has issued a gale warning for 9 p.m. Sunday to 4 a.m. Tuesday for the waters from Point Piedras Blancas north of Cambria to Point Arguello in northern Santa Barbara County.
Forecasters expect northwest winds to increase to 20-25 knots, with frequent gusts to 35 knots Sunday night through mid-day Monday.
Monday afternoon, winds are expected to kick up to 25-30 knots, with gusts to 40 knots before diminishing early Tuesday morning, according to the Weather Service.
Steep and hazardous seas between 11 and 15 feet are forecast to continue to Monday night.
A gale warning means that winds of 34-47 knots are imminent or taking place.
Vessels operating in gale conditions require experience and proper equipment, the agency warns, adding that mariners who don’t have the proper experience should seek a safe harbor.
