Extreme heat and wildfire smoke expected Labor Day weekend

District urges Valley residents to protect their health and reduce their energy use

With the extreme heat facing the Valley, the Valley Air District encourages residents to take action to keep cool, check on your family and neighbors, monitor air quality levels and reduce strain on the energy grid wherever possible. The record-breaking heat over the coming days could intensify ongoing wildfires, increase the potential for new wildfires to begin, and deteriorate air quality conditions throughout the Valley.

Valley residents are urged to protect their health during the coming days by staying indoors when possible, use central air conditioning to stay cool during the peak temperatures of the day, seek local cooling centers, and use in-home air filtration devices to reduce exposure to wildfire smoke when needed.

Here are three things you can do in coming days:

  • Help others: Check on your neighbors, particularly those who are elderly or mobility-challenged and remind them to hydrate. Safety tips can be found here.
  • Monitor Energy Use: Please reduce your electricity use. Electricity demand spikes during heatwaves by turning up thermostats and turning off appliances that are not in use. Pre-cool your home and make sure your devices are charged before 4 p.m.
  • Avoid Outdoor Activity: Stay indoors in cool temperatures. Air quality information is available at myRAAN.com. Extreme heat coupled with ongoing wildfires can contribute to unhealthy air quality.

Under these extreme conditions, wildfire smoke could drive air quality up to unhealthy levels. Poor air quality can trigger asthma attacks, aggravate chronic bronchitis, and increase the risk of heart attack and stroke. Individuals with heart or lung disease should follow their doctors’ advice for dealing with episodes of PM exposure. Those with existing respiratory conditions, including COVID-19, young children and the elderly, are especially susceptible to the health effects from this form of pollution.

Residents can use the District’s Real-time Air Advisory Network (RAAN) to track air quality at Valley locations by visiting myRAAN.com or through the EPA AirNow tool. In addition, anyone can follow air quality conditions by downloading the free “Valley Air” app on their mobile device.
