Air Quality Alert: Increasing Saharan dust combined with pollution from evening fireworks will enhance particle levels.


Increasing Saharan dust combined with pollution from evening fireworks will enhance particle levels. Furthermore, a surface high pressure system south of the Bayou State will lead to light winds, and partly sunny skies along with temperatures in the 90s will aid ozone production. These conditions will yield Moderate AQI levels for most cities. Light winds will continue to draw Saharan dust into Louisiana. Additionally, surface high pressure over the state will limit vertical mixing, and pollutant carryover from fireworks along with temperatures in the 90s and mostly sunny skies will enhance ozone formation. As a result, AQI levels will be Unhealthy for Sensitive Groups for New Orleans and Baton Rouge, and Moderate for the rest of Louisiana. Saturday, light westerly to southwesterly winds will begin to disperse Saharan dust. However, continued warm temperatures and mostly sunny skies will aid ozone formation. These conditions, along with pollutant carryover, will lead to Moderate AQI levels statewide.

This area includes East Baton Rouge, West Baton Rouge, Iberville, Livingston, Ascension and Pointe Coupee parishes. The weather conditions will be favorable for the formation of ozone. 

The Air Quality Index indicates that ozone will be at the orange level, which is unhealthy for sensitive groups. Increasing ozone levels may cause unhealthy air quality during afternoon hours. Active children and adults, the elderly and people with respiratory diseases, such as asthma, should avoid prolonged outdoor activities and exertion. 

Area residents are encouraged to take one or more of the following
voluntary actions to help reduce the formation of ozone::
• 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

Incorporating these tips into your daily routines can make a significant difference. We all have a stake in better air quality.
