Cancel your fireplace plans for Sunday, Bay Area.

Hear that? So don't burn wood on Sunday. Please.
The air pollution-watchers stopped short of declaring a "Spare the Air Day" day, which means that wood can in theory be burned. But burning wood could lead the air quality to get bad enough for a Spare the Air Day to be called before the winter season ends on Feb. 29.
