The National Weather Service office in San Diego said the fog will be followed by falling temperatures, with daytime highs 15 to 20 degrees cooler on Wednesday and Thursday.

The fog could cause problems for commuters on Interstate 5 and may lead to morning flight delays at Lindbergh Field. A dense fog advisory is in effect until 9 a.m.

“With a shallow marine layer and weak onshore flow, areas of dense fog will develop over the coastal waters and near the coast through sunrise, then spread locally inland past sunrise before clearing back to the beaches by mid- morning,” according to the weather service.

Visibility could to drop to less than a quarter mile at times in pockets of fog along Interstate 5.

The cooler weather later in the week will be accompanied by high winds as a low-pressure system passes through.

“A period of high winds is possible late Wednesday and Wednesday night over the mountains and deserts, along with hazardous small craft conditions in our coastal waters,” the weather service said.
