Authorities continue to warn of harmful and deteriorating air quality as smoke drifts into the South Valley region from numerous wildfires burning in the Bay Area, Salinas Valley and beyond.
Residents likely woke up this morning with their vehicles covered in ashes and enough smoke filling the air to obstruct visibility and complicate breathing. The River Fire, burning south of Salinas, grew from about 4,000 acres Monday afternoon to more than 10,000 acres the morning of Aug. 19, according to CalFire authorities.
Firefighters are also fighting the SCU Lightning Complex Fire, which consists of numerous wildfires throughout the Bay Area that have collectively burned more than 85,000 acres as of Aug. 19. One of these fires is burning east of Morgan Hill and Gilroy in Henry W. Coe State Park, and another is ablaze in the Santa Cruz Mountains. Thousands of residents have been evacuated.
The fires have caused smoke pollution throughout the region, and residents are advised to stay indoors due to the poor air quality. The Bay Area Air Quality Management District rates the Aug. 19 air quality index in South Santa Clara County at 107, which falls in the category “Unhealthy for Sensitive Groups.”
The air quality forecast for Aug. 20 shows the AQI rating will worsen to 157 in South County, according to the BAAQMD website.
The Monterey Bay Air Resources District rated the air quality for San Benito County in the generally “Unhealthy” range.
“An unhealthy level is defined as some members of the general may experience health
effects: members of sensitive groups may experience more serious health effects,” says a press release from San Benito County. “If you see smoke in the air or smell smoke, then there can be risks to your health.”
San Benito County authorities included the following advice in the Aug. 19 press release:
