This isn't fog in San Diego...it's haze from the fires. The sun is almost completely obscured on what would have normally been a blue-sky day.
This is ash on her car, even though the fires are miles away.
Tomorrow my sister is flying out of town. If she gets some pictures of the devastation from the air, I'll post them next.
As a resident of the San Diego area for many years, she knows many people affected by this horrible event. She and her family are lucky ones.
