Ozone is a harmful gas that can cause respiratory problems, such as asthma and bronchitis. During ozone season, it is important to take steps to protect your health, such as staying indoors on hot, sunny days and avoiding strenuous activity outdoors. 

You can also help to reduce ozone levels by driving less and using public transportation or biking whenever possible.

Ozone is formed when sunlight reacts with certain pollutants in the air, such as nitrogen oxides and volatile organic compounds (VOCs). These pollutants are released into the air from a variety of sources, including cars, trucks, power plants, and industrial facilities.

  • Coughing
  • Wheezing
  • Difficulty breathing
  • Headaches
  • Nausea
  • Fatigue
  • Heart attacks
  • Strokes

Children, the elderly, and people with respiratory problems are more susceptible to the effects of ozone.

Houston weather: Air Quality Alert extended, hot and dry Thursday evening

Air Quality Alert has been extended once again through Friday evening for the Houston area. That mean ozone levels in the atmosphere will remain elevated which could cause a problem for sensitive groups. Otherwise, we should be fairly quiet this evening and tonight with just a slim chance for a shower or storm. We are getting closer and closer to our holiday weekend! It looks like the weather pattern will remain on the quiet side with just isolated rain possible in the afternoon and near average heat for late May. Look for only a 10% chance for rain Friday through Sunday with rain chances increasing slightly to 20% for Memorial Day on Monday.
