What happened
The episode as NWS LIX wrote it up.
The remnants of Tropical Storm Allison moved over southeast Louisiana and south Mississippi during the night of June 10/11th and intensified. Some thunderstorms reached severe levels and produced damaging winds and short lived, weak tornadoes. Heavy rainfall also accompanied the storms with 5 to 10 inches of rainfall reported overnight. Flash flooding developed in several areas of poor drainage in Harrison and Jackson Counties with roadways, and some structures flooded. An area in Gulfport near Brickyard Bayou was reported to have been hard hit with a large number of houses flooded. Flash flooding was also reported near Bluff Creak near Vancleave. Heavy rainfall caused flooding of streets and roadways in Hancock and Pearl River Counties.
