Storm Surge/Tide — Hancock, Mississippi

2021-06-19 · Hancock, Mississippi

Event narrative

Storm surge flooding led to numerous roads in the Shoreline Park and Jourdan River Shores areas becoming impassable. Tide gauges in the area saw a 2-4 ft rise, resulting in up to 3 ft of inundation in the lowest lying areas. The combined effects of storm surge and heavy rainfall led to dozens of roads becoming impassable and approximately 100 homes were affected. High water rescues were necessary in the kiln area due to people driving around high water barricades.

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 to the Mississippi coastal Counties. Peak wind gusts across the region barely reached tropical storm strength.
