Current and forecasted air quality email or text notifications for the Reno/Sparks area
By selecting the air quality index (AQI) level you wish to receive notification, you can determine the frequency of air quality forecast and current notifications.  For those who are unusually sensitive to air pollution, the Moderate range or higher level is recommended. In addition to these forecast notifications, current notification AQI levels can also be selected to receive a notification for whenever the AQI is at or exceeds the Unhealthy for Sensitive Groups level.  There can be up to a one and a half hour delay from when the data is collected to when it is calculated and sent from EnviroFlash.

Know the Code - Burn Code icons
Our Know the Code - Burn Code program runs from November 1st through the end of February.  During the winter months, fine particulate matter (PM2.5) is our primary pollutant of concern and wood smoke from residential wood combustion is our number one source of PM2.5.  Fine particulates can build up during a cold air inversion which traps air and all of the human related air pollution at the ground-level.  During these cold and calm conditions, PM2.5 levels can get into the “Unhealthy” ranges.  Subscribers will receive one daily Burn Code during the four winter months with the AQI Forecast email that you select the frequency.  In order to receive all Burn Codes, be sure to select your AQI Forecast level to "Good."

The Green, Yellow, and Red Burn Codes mean:

Green - It’s okay to burn, but please burn only dry, seasoned wood. 

Yellow - Go easy on how much you burn or stop altogether. Compliance is voluntary but greatly encouraged. Reducing or stopping wood burning now can prevent air pollution from reaching unhealthy levels. 

Red - Run a red light and you risk getting a ticket. The same happens here when the burn code is red and you continue to burn. When inversions settle into our area and the Health District declares a Stage 1 Episode – this prohibits burning for 24 hours. Compliance is enforced at this stage. 


Health advisories (e.g. wildfires, dust storms)
All subscribers will receive health advisories, which are issued when air pollution is expected to quickly increase and reach the “Unhealthy” AQI level (>150).  Health advisories will be issued every day during an air quality emergency.


This service is free of charge. You are only required to provide your email and your ZIP code. This information will not be shared with any other organization and you can change your preferences at any time. With EnviroFlash, you will receive advance notice so that you can take action to reduce pollution and reduce your exposure to unhealthy air quality.
