The San Joaquin Valley Air Pollution Control District (APCD) issued an air quality alert for Valley residents yesterday due to smoke from California's wildfires. If you step outside and take a deep breath or just look at the hazy skies, you will quickly understand why.
If you want to get a little more information on just how bad it really is as measured by ambient air quality monitors, then check out the APCD's Real-time Air Advisor Network (RAAN). By using either a free app or by typing in your zip code at the RAAN website, you can see what the ozone and PM2.5 levels are in your area right now and throughout the day.
Again, because of the risk to your health, the APCD recommends that you avoid strenuous outdoor activities until the skies clear to safer levels.
