Winds were predicted to turn onshore in San Diego County Sunday, leading to breezy conditions across the mountains and deserts and a slight cooling for areas west of the mountains, though the deserts may remain hot, the National Weather Service said.
Low clouds and fog were blanketing the near-shore waters Sunday morning, with some coastal areas obscured. This was the result of a coastal eddy spinning about 30 miles offshore, the NWS said.
Fog could affect operations Sunday morning at San Diego International Airport, forecasters said.
Winds may increase Sunday afternoon across the mountains and desert slopes, with peak wind gusts occurring Sunday evening into early Monday morning and the highest gusts at 35 to 50 mph across wind-prone passes.

High temperatures along the coast Sunday were predicted to be 72 to 77 degrees with overnight lows of 53 to 58. Highs in the western valleys were expected to be 81 to 86 and 86 to 91 near the foothills, with overnight lows of 49 to 55.
Highs in the mountains were expected to be 82 to 91 with overnight lows of 46 to 56, and highs in the deserts were predicted to be 105 to 110 with overnight lows of 66 to 74.
Further cooling may occur Monday, forecasters said. A deepening marine layer could lead to more widespread low clouds and fog across the coastal waters, the coast and the western valleys Sunday night into Monday morning.
A pattern change late this week may lead to noticeable cooling and strong winds across the mountains and deserts, and a very deep marine layer.
