Dense Fog Expected Through Saturday and Sunday Mornings

Forecasters have placed a dense fog advisory in effect through Saturday morning and warn that another could be in place through early Sunday in Coronado and along the San Diego County coast.

The dense fog that rolled in along the San Diego County coast could be hazardous for drivers and cause airport delays through Saturday morning, the National Weather Service reported, and the process is likely to repeat Sunday.

A very shallow marine layer started to move inland along the northern beaches Friday afternoon then spread inland, where areas of dense fog were developing, according to the NWS.

Forecasters issued an advisory set to remain in effect until 9 a.m. Saturday, though the fog might not clear completely until late morning.

“A dense fog advisory means visibilities will frequently be reduced to less than one quarter-mile,” the statement said. “If driving, slow down, use your headlights and leave plenty of distance ahead of you.”

The weather service said the fog would likely impact travel along Interstates 5, 8 and 805, state Routes 56, 78 and 163 and other areas within 10 miles of the coast. Visibility was expected to fall to a quarter-mile or less and could reach as low as 100 feet.

The foggy conditions could also cause delays at San Diego International Airport and McClellan-Palomar Airport in Carlsbad.

Weather service officials said the patchy dense fog should clear out by 11 a.m. Saturday, but could redevelop along the coast Saturday night into Sunday morning.

By Monday night fog is still expected around Coronado, but in patches and not as thick as Saturday and Sunday. Highs are expected to be in the mid-to-upper 60s and lows in the mid-50s for the period.

    Our weather reports change frequently. or the latest update, do a search on "weather San Francisco." I’ll bet it will be cooler than you expect. And if it is windy and foggy, it really feels cold.
