Air Quality Alert issued for Wednesday

A strong high pressure system over the ArkLaTex could enhance ozone levels in the atmosphere and create unhealthy conditions for people with sensitive conditions today.

Upper-level ridging will keep sunny and very hot weather conditions in the ArkLaTex.  The sun and heat can enhance ozone formation in the atmosphere.

Light winds are also forecast through most of the week, and that could also add to air quality concerns.  When winds are light, it's harder for pollutants in the air to disperse.

That means the air quality in the ArkLaTex could be unhealthy for sensitive groups, such as those with respiratory problems like asthma.  If you have asthma, you may experience some wheezing or coughing; you are advised to avoid long hours outdoors today.

These recommendations come from the Louisiana Department of Environmental Quality, which has declared today an Ozone Action Day in Caddo, Bossier and DeSoto parishes.  The Northeast Texas Air Care Group has also declared an Ozone Action Day in east Texas areas including Marshall, Longview and Tyler.

The Louisiana Department of Environmental Quality offers these tips for curbing ozone levels in your area:

• Drive less. Carpool, walk and bike, combine errands and care for your car. Be sure your gas cap is on tight.
• Refuel your vehicle, mow grass and use gas powered lawn equipment and off road vehicles after 6 p.m.
• Postpone chores that use oil based paint, varnishes and solvents that produce flame.
• If you barbeque, use an electric starter instead of starter fluid.
• Take your lunch to work or walk to lunch
• Conserve Energy in your home
