Waterspout August 8, 2025 · Lake Ponchartrain and Lake Maurepas, Gulf of Mexico

Where the report was made, with tornadoes recorded within 15 miles over the years.

What the National Weather Service wrote

Broadcast media relayed a picture of a waterspout crossing the Pontchartrain Causeway just north of Metairie.

The wider storm

A typical summertime pattern was in place across the region. The very warm waters in nearshore and tidal lakes provide a unique mesoscale environment which promotes nocturnal thunderstorm development. A waterspout developed along the outflow boundary of that storm and dissipated as it reached the coast.

Began near Municipal Yacht Harbor - Weatherstem (30.0200, -90.1600).
