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 are predicted to reach 77 degrees, 86 in the western valleys, 91 near the foothills, 91 in the mountains, 110 in the deserts, according to the weather agency.

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.

Patchy fog with visibility one nautical miles or less was expected Sunday morning over coastal waters. Some may linger into the afternoon hours.

A total lunar eclipse will occur Sunday evening, but low clouds and fog may obscure the moon along beaches and five miles inland. Elsewhere, a few thin high clouds shouldn’t affect viewing.

San Diego moonrise will be at 7:32 p.m. Sunday. The total eclipse beings at 8:29 p.m. and ends at 9:53 p.m.
