Survey Summary:
A tornado touched down just north of the river and south of the
airport in Kenner and took the roof off a large building. It was
noted the roof material was severely corroded and rusted. The
tornado moved north and convergence in downed trees was seen just
to the east of a cemetery. The tornado continued to track north-
northeast, with trees down near the railroad tracks and power
lines down just north of the tracks, where it looks like the
tornado lifted.

A storm likely spawned a waterspout near the northshore of Lake
Pontchartrain and moved onshore as a tornado near Guste Island
around 2:50 AM CDT. The tornado tracked to the north-northwest 
across mainly uninhabited swamp lands about two miles west of the 
Tchefuncte River. Sporadic softwood and hardwood tree damage was 
noted on the eastern shore of the inlet. Additional damage was 
likely but it was inaccessible during the the storm survey. The 
damage that was viewable from the ground survey indicates an EF-0
tornado with estimated peak winds around 75 mph. 

The tornado was also confirmed by KLIX radar data with a tornado 
debris signature evident as it was crossing the inlet at 2:53 AM 
CDT. The tornado quickly lifted around 2:55 AM as it approached 
the northern shore of this inlet.


EF Scale: The Enhanced Fujita Scale classifies tornadoes into the
following categories:

EF0...Weak......65 to 85 mph

EF2...Strong....111 to 135 mph
EF3...Strong....136 to 165 mph
