Hot weather over the next few days could cause a build up of smog-forming ozone.
High temperatures in the 80s and 90s are expected throughout Washington for the next several days before cooling begins over the weekend, forecasters said.
Ozone is triggered by sunlight mixing with motor vehicle exhaust and vapors from paints and solvents. Shortness of breath, coughing and painful inhalation are possible effects from ozone exposure.
“You can do a number of things to reduce the air pollution that forms smog in your communities,” said Clint Bowman, a meteorologist for the Washington Department of Ecology.
Driving less, avoiding the use of lawn mowers and other small engines and observing outdoor burning bans will reduce ozone build up, Bowman said.
Officials also recommend waiting until morning or evening to refuel your vehicle and turning off your vehicle while you’re waiting in line.
