9 damage points were recorded along this path by NWS LIX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 82 mph.

• roof shingles, chimney and siding torn off. Siding scattered on front side of house and stuck in tree next to neighbors house to the east. Fence blown over facing north and east.
• roof torn on south facing side. fence down. tree branches down everywhere.
• Pergola destroyed in pool, siding ripped off, South-facing double doors blown in, large cedar swing set/tree house blown over, branch impounded on east facing side of shed. Large oak tree uprooted (fell to the north) and hit the house. A large camper in back yard was overturned on other side of fence - rolled to the north and fell into neighbors house on north side (it may have gotten lofted as it didn't completely destroy the fence). The worst damage occurred at this residence.
• most concentrated damage. damage faces to the north and east. Subtle convergent pattern. Car windows blown in. Garage door bashed in from trampoline. Shingles peeled and chimney blown over. Numerous fences blown over from about five different houses. Several fences were just built.

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.

Several buildings in Camille Village Apartments sustained minor damage to the siding and front awnings. Two buildings had their AC units blown over. One of the AC units was not found. An awning attached to the front of one of these building was completely destroyed. The roofing and awning material was lofted and found about 1,000 yards to the northwest past a fence and area of trees.

0 minutes of warning. NWS LIX issued a tornado warning for this county at 05:37 UTC, 0 minutes before the tornado touched down, in force until 06:00 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Marginal Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 00:48 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

The radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

The Mobile radar (KMOB), 103 km away, was scanning. The volume nearest the touchdown began at 05:35 UTC.

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.
