An air-quality alert has been issued for the San Joaquin Valley because of smoke from wildfires burning in Monterey and Santa Barbara counties and will extend through Wednesday, the San Joaquin Valley Air Pollution Control District said.
Air quality was poor Tuesday because of the smoky skies, the air district said. In the Fresno area, smoke is blowing into the region from the 117,600-acre Soberanes Fire that began burning in Big Sur in late July.
In Kings, Tulare and Kern counties, smoke has blown in from the 4,500-acre Canyon Fire that started Saturday in northern Santa Barbara County, said Modesto Vasquez, a meteorologist with the National Weather Service office in Hanford.
Never miss a local story.
Wildfire smoke causes ozone to form, which can cause lung disease, asthma attacks and increased risk of heart attacks and stroke. People should stay indoors, especially the elderly and young children, the air district said.
If you can smell smoke or see ash, you should treat air quality conditions as unhealthy for all groups.
Wednesday’s forecast high temperature in Fresno is 90 degrees, down from the 95-degree reading Tuesday afternoon.
Conditions will keep cooling into Thursday, when a cold front will pass through the region and drop temperatures into the 70s.
