From the latest Texas Commission on Environmental Quality (TCEQ) report:
Saturday 4/24/10 – If ozone precursor levels are high enough, ozone levels could reach moderate levels in the afternoon and evening. Highest concentrtions are most likely on the east side of the Houston metro area and downwind into the Beaumont-Port Arthur area. Smoke from agricultural burning in Mexico and Central America is predicted to bring fine particulates into the moderate range. Elsewhere in the state the air quality is predicted to be in the good range thanks to moderate winds.
Sunday 4/25/10 – Winds may be light enough for ozone to reach moderate or possibly higher levels in parts of Southeast Texas in the afternoon and early evening. The highest concentrations will most likely be on the east and southeast side of the Houston area. Elsewhere in the state moderate winds and lower background levels should keep air quality in the good range.
Here is some information from the American Lung Association:
Effective tips for protecting you and your family from the dangers of air pollution:
1. Check daily air quality levels and air pollution forecasts in your area.
2. Avoid exercising outdoors when pollution levels are high.
3. Walk, bike or carpool. Combine trips. Use buses, subways, light rail systems, commuter trains or other alternatives to driving your car.
4. Fill up your gas tank after dark. Gasoline emissions evaporate as you fill up your gas tank. These emissions contribute to the formation of ozone, a component of smog. Fill up after dark to keep the sun from turning those gases into air pollution.
5. Don’t burn wood or trash.
6. Don’t allow anyone to smoke indoors and support measures to make all public places smoke free. Dangerous particles from cigarette smoke can remain in the air long after a cigarette has been extinguished.
7. Get involved. Review your community’s air pollution plans and support state and local efforts to clean up the air.
