SAN FRANCISCO -- The Bay Area Air District has extended a Spare the Air alert through Monday, October 5 because of a forecast of hot weather and light winds that is expected to lead to elevated pollution levels. It was previously in effect for Saturday and Sunday.
The National Weather Service has issued a Heat Advisory for 11 a.m. Saturday through 10 p.m. Wednesday for most of the Bay Area besides some places along the coast and in the North Bay because of expected triple-digit inland temperatures.
The air district said the weather conditions are expected to produce elevated concentrations of ozone, otherwise known as smog.
On Spare the Air days, outdoor exercise is advised only in the early morning hours when smog levels are lower. The pollution is particularly harmful for young children, older adults, and people with respiratory and heart conditions, according to the air district.
People can find out when a Spare the Air alert is in effect by visiting the organization's website, calling (800) HELP-AIR, downloading the Spare the Air app on their smartphone or find Spare the Air on social media.

What are Spare the Air days?
Air quality in the Bay Area can be unhealthy at times throughout the year.
Spare the Air Alerts are called when ozone pollution is forecast to reach unhealthy levels. Ozone, or smog, can cause throat irritation, congestion, chest pain, trigger asthma, inflame the lining of the lungs and worsen bronchitis and emphysema. Long-term exposure to ozone can reduce lung function. Ozone pollution is particularly harmful to young children, seniors and those with respiratory and heart conditions.
When a Spare the Air Alert is called, outdoor exercise should be done only in the early morning hours when ozone concentrations are lower. Residents are encouraged to reduce air pollution every day by rethinking their commute and avoiding driving alone.
