FAIRFIELD — People with sensitive respiratory systems are advised to limit their outdoor activities Sunday while everyone else is asked to limit their driving to help keep pollution levels down.
The air quality warning comes as the National Weather Service on Saturday issued a fire weather watch for a large swath of the coastal region from the North Bay well past Santa Rosa, south into Monterey County and down to King City.
The area extends east into Solano County and approaches both Fairfield and Vacaville.
Thunderstorms and lightning strikes are possible. The fire weather watch is in effect Sunday evening through Tuesday night.
A fire weather watch is issued when what the National Weather Service describes as critical fire weather conditions may occur. In this instance, dry grasses and other fuel sources across the region may ignite if struck by lightning, even if it’s raining.
Meanwhile the Bay Area Air Quality Management District issued a Spare the Air alert Saturday in anticipation of poor air quality Sunday across the region.
Each summer’s Spare the Air season generally runs from May through mid-October when clear skies, hot temperatures, lighter-than-usual winds and strong temperature inversions combine to create smoggy conditions, according to the air quality management district’s website.
Residents are asked to cut back on any activities that cause pollution. Those include driving, using oil-based paints, gasoline-powered lawn mowers or household aerosol products like hair sprays. People who are sensitive to unhealthy air are asked to limit their time outdoors, particularly in the afternoon.
