New Orleans, Louisiana – Strong winds and extremely low humidity are triggering a Red Flag Warning across southeast Louisiana and southern Mississippi on Sunday.
According to the National Weather Service in New Orleans, the warning remains in effect from 9 a.m. to 6 p.m. CST Sunday due to critical fire weather conditions.
Forecasters expect north winds of 15 to 25 mph, with gusts reaching up to 35 mph. Relative humidity levels could fall as low as 20 to 25 percent during peak afternoon hours. That combination of dry air and gusty winds significantly increases the risk of fast-moving wildfires.
The warning includes Baton Rouge, New Orleans, Houma, Thibodaux, Slidell, Hammond and surrounding parishes, along with coastal Mississippi counties including Hancock, Harrison and Jackson. Major roadways such as Interstate 10, Interstate 12 and U.S. 90 fall within the affected region.
Officials warn that any fire that develops could ignite quickly and spread rapidly. Outdoor burning is strongly discouraged during the warning period.
A Red Flag Warning means critical fire weather conditions are either occurring or expected shortly. These conditions can lead to extreme fire behavior, especially in areas with dry vegetation.
The heightened risk may affect weekend outdoor plans, including yard work, grilling and agricultural burning. Residents are urged to properly discard cigarettes and avoid activities that could create sparks.
Conditions are expected to improve after 6 p.m. Sunday as winds gradually diminish and humidity levels recover.
