2021-06-19 · Southeast St. Tammany Parish, Louisiana

Event narrative

Tide gauges on the southeast side of Slidell registered a 1 to 3 ft rise due to storm surge.

Wider weather episode

A tropical wave meandered in the Bay of Campeche for a few days in mid June before slowly tracking northeastward towards the Louisiana coastline. It actually didn't attain tropical storm status until after it made landfall in Terrebonne Parish on the early morning of June 19th. The generally weaker nature of the storm meant that wind and surge were the lesser of impacts. However, a band of very heavy rainfall developed on the east side of the storm and brought several inches to upwards of one foot of rain from the eastern side of New Orleans metro to St. Tammany Parish. Peak wind gusts across the region barely reached tropical storm strength.
