e-Forecast Service - It's Free !

The American Lung Association® in Washington has a tool to give residents of the Northwest fast, accurate notification when air quality has deteriorated and may affect health-sensitive people. It's called the Breathe Easy Network, an email air quality forecast service.

The Breathe Easy Network provides advance warning when air quality deteriorates in your community. This can help you in three ways:

1.You get early warning about possible pollution problems so you can head off asthma triggers before they affect you or family members.
2.You will be able to schedule and plan around "bad air" days by following specific tips to protect you and your family's health.
3.You will be able to make sure medications and treatment options are in place when you need them, should you need them.
The Breathe Easy Network plays an important role in relaying health information to sensitive populations before government actions like Smog Watch or Burn Bans are triggered. There are hundreds of people in this region that feel the health effects from breathing dirty air at levels below what federal health standards consider "unhealthy" air.

Health sensitive people include:

  • People with respiratory diseases, such as asthma
  • Children
  • Adults who are active outdoors
  • Adults over 50 years of age
  • People with unusual susceptibility to air

How it works

1.The Washington state's Department of Ecology - Air Quality Program gathers Ambient Air Quality Data and Information from monitors throughout the state. Based in part on the Department of Ecology's monitoring information, local Washington state air quality agencies forecast today's and tomorrow's air quality for ten different areas in Washington. By 11:00 daily these forecasts are sent to the EPA AirNow website which displays today's and tomorrow's.

2.Daily in the morning, the American Lung Association® in Washington check's the EPA AirNow website and if any "EPA AirNow area" reports something other than a "Green/Green" forecast the American Lung Association® in Washington sends an alert with "Today's" and "Tomorrow's" forecast to one or more of the three "Breathe Easy Network area(s)".

3.A "Green/Green" forecast will only be sent once, following a forecast that is other than "Green/Green".

Air quality is acceptable; however, for some pollutants there may be a moderate health concern for a very small number of people who are unusually sensitive to air pollution.



Members of sensitive groups may experience health effects. The general public is not likely to be affected.



Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.



Health alert: everyone may experience more serious health effects.


> 300

Health warnings of emergency conditions. The entire population is more likely to be affected.
