In a notification from the DEQ it tells us that Southerly to southeasterly winds brought a significant plume of Saharan dust into Louisiana, Thursday, June 25, 2020,increasing particle concentrations in the air.
Therefore, despite scattered thunderstorms aiding mixing and limiting ozone formation, Air Quality Index levels will be mid- to high-Moderate in most cities.
Friday light to moderate southerly winds will continue to transport Saharan dust into the Bayou State. A decrease in thunderstorm activity will reduce atmospheric mixing. This means, AQI levels will be Unhealthy for Sensitive Groups across southern Louisiana and Moderate in central and northern Louisiana.
Saturday's southerly winds will gradually transport cleaner air into the state, while increasing thunderstorm development will aid mixing. However, pollutant carryover from today will yield Moderate AQI levels statewide.
The Air Quality Index indicates that PM2.5 will be at the orange level, which is unhealthy for sensitive groups. Increasing PM2.5 levels may cause unhealthy air quality throughout the day. Active children and adults, the elderly and people with respiratory diseases, such as asthma, should avoid prolonged outdoor activities and exertion.
People with heart or lung disease, older adults, children and teens – take any of these steps to reduce your exposure:
• Choose less strenuous activities (like walking instead of running) so you don’t breathe as hard.
• Shorten the amount of time you are active outdoors.
• Be active outdoors when air quality is better.
Incorporating these tips into your daily routines can make a significant difference.
