New Orleans, Louisiana – Thunderstorms are set to intensify across southern Louisiana through Tuesday, bringing daily rain chances above 70% and increasing the risk of flash flooding and travel slowdowns in the New Orleans metro area.
According to the National Weather Service, the weekend begins with scattered storms today, with the likelihood rising sharply Sunday into Monday. By Tuesday, forecasters expect up to a 90% chance of thunderstorms, some of which may bring heavy downpours, gusty winds, and brief street flooding during afternoon peak hours.
Communities from Metairie and Gretna to Kenner and Chalmette should expect possible delays on major routes like I-10 and US-90 during storm activity. Daytime highs will hover near 90°F, but high humidity will push heat indices well above that, increasing health risks for those outdoors without shade or hydration.
Drivers should plan for low visibility and wet pavement during evening commutes, especially Monday and Tuesday. Residents are urged to secure loose outdoor items and ensure drainage systems are clear.
Rain and storm chances linger into midweek, though confidence in severe weather decreases slightly by Wednesday. Another update will be issued if flood advisories or additional warnings are posted.
