If you have checked out or used the Fire and Smoke Map in the past, you might want to check it out again.  The USDA Forest Service and the EPA recently updated the map to offer additional functionality, including new icons, additional site-specific air quality information, and ozone/PM10 alerts. You can find out more below from the official announcement.

(Official Announcement) A new version of the Fire and Smoke Map on AirNow is now live. No need to change your saved link, when you click https://fire.airnow.gov/, version 4 will be there.

EPA and Forest Service Release Updated AirNow Fire and Smoke Map | US EPA
EPA News Release: La EPA y el Servicio Forestal publican el mapa actualizado de incendios y humo de AirNow

If you would like to continue using Version 3, it is still available.

The updated map has a new look and feel, is designed to load more quickly, and includes information not available in the previous versions, such as:

• Air monitoring information on coarse particle pollution and ozone
• More information on individual wildland fires, including the type of fire and level of fire activity, when available
• Information from low-cost fine particle sensors in Canada, in cooperation with Environment and Climate Change Canada

The new version of the map allows users to see activity recommendations at a glance – or to expand the information to see more, including more information on actions to take to protect your health, charts showing how air quality has changed over the past week, and whether there are other fires within 30 miles of their locations. The map makes Smoke Outlook alerts more prominent and links to these forecasts, where available, to help the public better understand the possible impacts of smoke over the next several days. The Forest Service-led Interagency Wildland Fire Air Quality Response Program issues Smoke Outlooks for certain large fires.

You can view the Fire and Smoke Map on the AirNow website or select the smoke icon on the bottom right of the AirNow smartphone app. To view the map in Spanish or to select a modified AQI color scale for users with certain color vision deficiencies, click the settings icon at the top right corner of the map.
