UNHEALTHY AIR LESSENS LATE WEDNESDAY

Share with Friends

Woodsmoke carried south from fires in northwest California continues to hang over the North Bay Wednesday, but the worst of the smoke should begin to clear by Wednesday evening.

At 1PM Wednesday air quality readings had reached unhealthy levels across much of the region.

Central Sonoma, Napa and Lake counties were among those most impacted. There were many readings from 100-150, which is considered unhealthy for sensitive individuals. The highest readings over 150 are considered unhealthy for everyone and people should limit their time out of doors or consider using a mask that filters fine particulates.

Surface smoke forecasts are for the worst of the pollution to lessen by later on Wednesday evening, and clearing from the area by Thursday afternoon.

Meantime, wind and heat impacts will peak on Wednesday, with temperatures near 100 degrees in the hottest North Bay locations and gusty winds in the hills. Both will lessen by late Wednesday, and Thursday will be cooler.

A more dramatic cooldown should arrive on Friday.
