The air quality in the Tri-Valley, like the rest of the Bay Area, remains in very unhealthy conditions with smoke inundating the region’s air basin from massive deadly wildfires raging in Napa, Sonoma and Solano counties, according to the Bay Area Air Quality Management District.
All Pleasanton Unified School District campuses are set to remain open as usual on Thursday amid the poor air quality.
PUSD officials announced Wednesday that precautionary measures would be put in place at schools due to smoke through the end of the week. They include holding outdoor recess and physical education indoors, cancelling after school outdoor athletic activities and keeping windows and doors shut.
District spokesman Patrick Gannon said Wednesday that officials were still determining whether any Friday evening or weekend athletic events would be impacted.
Meanwhile, several parts of the Bay Area have been included in an expanded Red Flag Warning for most of Thursday, alerting residents of the high fire danger due to forecasted low humidity and gusty off shore winds, National Weather Service officials said.
As of Wednesday evening, areas under the warning include the North Bay Mountains, the East Bay Hills and Diablo Range, the Santa Cruz Mountains, the Santa Lucia Mountains, and the inland mountains in Monterey County. The warning is in effect through Thursday afternoon.
At least 21 people have died and more than 170,000 acres have burned in recent days in 22 major fires throughout the state, according to Cal Fire.
