The National Weather Service is cautioning San Diegans about dense fog through Tuesday morning.
The Dense Fog Advisory was issued for coastal areas in San Diego and Orange counties until 10 .a.m, Tuesday, according to the NWS.
"This is mostly for the coast, so we’re going to see very low visibility and it’s going to be tough to drive," NBC 7 Meteorologist Sheena Parveen said of the advisory. "Make sure you have your low beams on."

Visibility drops significantly under dense fog, especially on the roadway. The NWS said drivers will have trouble seeing past a quarter-mile.
San Diego Airport’s flight status tracker showed about two dozen delays and cancellations Tuesday morning but it was unclear if they were caused by fog.
On Monday night when the fog advisory was first issued, about 50 delays were reported but a spokesperson for SAN said fog was not affecting any flights.

The county will face a cooldown as the temps for the region decrease. Over the past weekend, San Diego County experienced unseasonably warm temperatures that were similar to that of summer.
"For today, it’s going to be a lot cooler," Parveen forecasted. "Our weather pattern is changing from what we had over the weekend and yesterday. More of an onshore flow."
More cloud coverage is expected during the upcoming weekend.
