Flash Flood — May 16, 2024
Continual progressive flow aloft coupled with unstable air ignited thunderstorms across southeastern Texas during the afternoon hours. These storms formed into a linear complex and traversed along a northward advancing warm front draped across the gulf coast. Aided by ample instability and favorable wind shear, this cluster organized into a damaging wind risk across coastal Mississippi. Multip...
Tropical Storm — Sep 11, 2024

Coastal counties of Mississippi experienced sustained tropical storm force winds and gusts which caused mostly minor damage to some homes and powerlines. A storm surge of 4-6 feet inun...

The line of severe thunderstorms produced strong straight line winds, extensive flash flooding in the New Orleans metro area and several tornadoes. 12 tornadoes...

On a northwestward track, Ida intensified into a hurricane on Aug...

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...
