The Bay Area Air Quality Management District has issued a Spare the Air alert for today in Pleasanton, the Tri-Valley and the greater Bay Area.
The National Weather Service is calling for temperatures today to reach a high of 102 degrees by mid-day with near record temperatures again on Tuesday .
As hot as it's predicted, today's high would fall short of the record-high temperature for Pleasanton and the Tri-Valley of 105 degrees on this date in 1963.
Today's smog alert is the third consecutive and the eighth for the summer season, Air Quality Management District spokeswoman Kristine Roselius said.
"We may have another one on Tuesday as well," Roselius added.
Today the Tri-Valley is expected to be sunny with temperatures in the lower to mid 90s. Winds of 5 to 10 mph are expected.
"We're hoping that people re-think their commute and take carpool or transit instead of driving alone," Roselius said.
There is no free transit today, and there is no wood-burning ban in place. Wood burning bans are common during winter Spare the Air alerts because of the particulate matter contained in wood smoke.
The air district monitors daily air pollution levels and produces air quality forecasts every day based on an index developed by the U.S. Environmental Protection Agency.
When the index indicates unhealthy concentrations of ground-level ozone -- commonly known as smog -- the air district issues the Spare the Air alerts.
The Bay Area Air Quality Management District is a regional agency chartered with safeguarding air quality in the nine-county Bay Area.
