Weather Alert- Tuesday, June 16th, 2026

Please stay weather aware this week. Multiple rounds of showers and thunderstorms are expected Tuesday through Friday, with the greatest chance for significant impacts currently expected on Thursday.

The biggest concern is heavy rain and possible flash flooding. Most areas could receive 3 to 6 inches of rain by Friday, but some locations may see much higher amounts if storms repeatedly move over the same area.

Potential impacts include:
• Street flooding and flooding in low-lying areas
• Heavy downpours with rainfall rates of 2 to 5 inches per hour
• Frequent lightning
• Wind gusts up to 40 to 50 mph
• Rising water levels in rivers, bayous, streams, and along Lake Pontchartrain

A Flood Watch remains in effect through Friday morning.

While not everyone will experience flooding, conditions can change quickly. Never drive through flooded roadways, and use extra caution during periods of heavy rain.

Need sandbags? St. Tammany Parish has opened a self-service sandbag station in Slidell at 34783 Grantham College Drive.

We’ll continue to share updates as conditions change. Please monitor local forecasts and be prepared for periods of heavy rain throughout the week.
