Spring snuck up on me this year–not that I’m complaining! It doesn’t seem that long ago that the news was monopolized by winter weather warnings and threats of snowstorms. I’m more than happy to put those snow boots away and slip into my favorite summer sandals! The advent of warmer weather also means we’re heading into ozone forecast season which is when ground-level ozone, created by pollution from sources like cars and smokestacks, is at its highest.
High amounts of ground-level ozone can worsen asthma symptoms, so it’s key for asthmatics to check the forecast daily, which is posted to our Asthma Therapy page. Ozone forecast season stretches from April 1 to October 31 in North Carolina and serves as a reminder to check the forecast before heading outdoors.
Ozone Levels and Air Quality Forecasts
The forecast is color coded to indicate air quality and the potential health implications:
- Good: Code Green
- Moderate: Code Yellow – Dangerous to those with extreme asthma
- Unhealthy For Sensitive Groups: Code Orange
- Unhealthy For Most Everyone:Code Red
- Very Unhealthy: Code Purple – The whole population is at risk; this is an emergency condition.
The air quality forecast is published each day at 3pm to help you plan your outdoor activities for the following day. In addition to accessing the forecast on our website, you can also sign up for email, phone, or mobile app alerts via the Environmental Protection Agency’s AirNow website.
Ozone forecast season isn’t just a reminder to monitor air quality; it can also inspire us to take steps to improving air quality. Cleaner air means fewer high ozone days, healthier lungs, and more opportunities to enjoy the outdoors. One step you can take to improve air quality is to choose sustainable transportation for your daily commute to work. Rethink your commute by carpooling, vanpooling, biking to work, working from home, or taking the bus. Many local transit agencies offer financial incentives for switching over to a sustainable mode of transportation – like GoTriangle’s GoSmart program. Choosing alternative transportation can also help you save money on gas and vehicle maintenance. It’s been several years since our last code red ozone day and I hope this ozone forecast season proves to be a healthy and safe one!
