Air quality intensified Monday as a thin haze of contamination crept over Bay Location skies.

However Mondays minor smog is not a significant cause for concern, air quality authorities stated.

Smoke from the Creek Fire and other active wildfires in the Sierras stayed up in the environment above the Bay Area and is not expected to have a considerable effect air quality throughout the region, National Weather Service meteorologists stated.

The increase in smoke and other particulates is likely due to regional property wood burning, not fumes from wildfires smoldering in the Sierra Mountains, said Erin DeMerritt, a spokesperson for the Bay Area Air Quality Management District.

Vallejo taped the poorest air quality in the region as conditions there inched closer to unhealthy air quality levels. Berkeley, East Oakland and San Jose likewise saw decreases after a stretch of clear skies.

Cities around the region recorded moderate levels of air contamination simply after dawn, with conditions reaching levels unhealthy for delicate groups. Those with breathing illnesses are being encouraged to limit extended outside exertion.

” Its not unusual to see raised particulate matter readings this time of year,” stated DeMerritt, who included that smoke particles tend to develop in the air on cooler nights before the winter rains arrive.
