Expect unhealthy to poor air quality in Bay Area Sunday
Smoke and haze from the Glass Fire are blanketing the Bay Area on Saturday and a Red Flag Warning is in effect for the North Bay Mountains overnight as warm, dry and locally gusty conditions persist.

SAN FRANCISCO (KGO) -- Northwest winds are providing some cooling Saturday along the coast with a little more moisture in the air.

This is some good news but there still is a whole lot of smoke and haze in our atmosphere on Saturday

High level smoke at about 4,000 feet will continue to adversely affect our air quality.

Sensors are indicating moderate to poor air quality on Saturday, but on Sunday unhealthy levels are predicted in the North Bay and East Bay Valleys.

In addition, gusty winds up to 30 mph will continue to fan the flames of the Glass Fire making for another day of critical fire weather despite the slightly cooler coastal temperatures and wind shift Saturday.

A Red Flag Warning has been reissued for the North Bay mountains overnight as warm, dry and locally gusty conditions persist, the National Weather Service announced on Saturday afternoon.
