New Orleans, La. – Thunderstorms could complicate Labor Day plans across southern Louisiana Monday, with drivers facing wet pavement and reduced visibility along I-10. Travel delays are possible through the afternoon as scattered storms move into New Orleans, Gretna, and surrounding parishes.
According to the National Weather Service, a 40 percent chance of showers and thunderstorms arrives late Monday morning, peaking between 1 p.m. and 5 p.m. Heat index values could push near 95°F before rain begins.
