Unhealthy Ozone Pollution Coming: 'Spare The Air' — Again — In East Palo Alto, Officials Say

Another Spare the Air alert has been issued for the Bay Area for Friday, the second day in a row and the 11th time this year that regional air quality officials have issued the alert warning of excessive smog. Triple-digit temperatures, light winds, combined with smoke from wildfires elsewhere in Northern California and in Oregon, are expected to create unhealthy levels of ozone in the region, according to the Bay Area Air Quality Management District.

"The Labor Day heat wave is expected to bring unhealthy air quality throughout much of the inland areas of the Bay Area," air district executive officer Jack Broadbent said in a statement.

Air district officials are encouraging people to avoid exercising or doing outdoor activities during the hottest part of the day. People should also take public transit, carpool or consider working from home to avoid the number of cars on the road creating smog.

People can find out when a Spare the Air alert is in effect by registering at www.sparetheair.org, calling (800) HELP-AIR, downloading the Spare the Air smartphone app or connecting with Spare the Air on Facebook or Twitter.
