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.

A tornado touched down on intermittent patch in rural Hancock County. Several houses suffered minor damage, several large trees were blown down as well as large tree branches. A barn was also damaged.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

The Storm Prediction Center had this point in a General Thunderstorms Risk. The outlook in force was issued at 05:57 UTC.

HEAVY RAIN ALONG WITH EMBEDDED STRONG THUNDERSTORMS NOW FIRING OVER
EXTREME S CENTRAL AND SE LA AND EXTENDING OVER THE MS COAST AS THE
REMNANTS OF ALLISON...NOW A TIGHT AREA OF LOW PRES...MOVES ENE
ACROSS SE LA. BOTH THE 00Z AVN AND ETA NOT INITIALIZED WELL OVER THE
CENTRAL GULF COAST AS BOTH HAVE THE AREA OF LOW PRES TOO FAR TO THE
W WHICH MAKES THE QPF NOT VERY RELIABLE FOR THE SHORT TERM. OF THE
TWO...THE ETA LOOKS TO BE CLOSER TO THE CURRENT MESO PATTERN SO WILL
MORE OR LESS TREND TOWARD THIS SOLUTION STARTING 24HR OUT. IN THE
MEAN TIME...WILL GO WITH EXTRAPOLATION IN TRYING TO PIN DOWN THE
PRECIP FORECAST WHICH WILL PLACE THE HIGHEST POPS WHERE CONVECTION
IS FIRING MOST. LIKEWISE...WILL TONE DOWN THE FFA TO INCLUDE ONLY
THOSE AREAS MENTIONED ABOVE WITH A FLOODING THREAT. BEYOND THE FIRST
TWO PERIODS...WILL PRETTY MUCH LET CURRENT PACKAGE RIDE WITH
TRENDING BACK TOWARD A CLIMO PATTERN HIGHLIGHTING A CHANCE FOR
MAINLY AFTERNOON AND EVENING SHOWERS AND TSTMS WITH TEMPS REBOUNDING
BACK TOWARD SEASONAL TRENDS.

29 more were confirmed in the United States that day.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
