Dense-fog advisory issued for Central Coast

The National Weather Service has issued a dense-fog advisory that’s in effect through 9 a.m. Monday.

The advisory covers the whole Central Coast, but particularly the cities of San Luis Obispo, Pismo Beach, Morro Bay, Cambria and San Simeon, as well as Santa Maria, Lompoc and the Vandenberg Air Force Base area.

Forecasters warn that visibilities could be as low as a quarter of a mile or less as fog becomes widespread Sunday night and into Monday morning.

Visibility could also reduce suddenly with denser patches of fog, making driving more dangerous.

The Weather Service warns that highways 1, 101, 135 and 246 are likely to be hit by dense fog.

The agency suggests slowing down on the road, using headlights even during daylight and leaving plenty of distance from other vehicles.

Fog can also make road surfaces slick, forecasters warn.
