Tornado began in old Mandeville near the corner of Kleber St and 
Monroe St. It then began moving to the east with mainly tree 
damage along as it crossed Hutchinson, Massena, and Maple Streets. 
There were numerous trees both hardwood and softwood that were 
snapped or uprooted and a few fell on houses and vehicles. Some 
of the strongest tree damage occurred along Hutchinson and Massena 
where a few very large hardwood trees, about 4 feet thick were 
snapped at the base. As the tornado crossed over Maple street it 
did lead to some minor roof damage to a small building on the 
campus of Mandeville Elementary. The tin roof was peeled up back 
to the west. The tornado continued to the east leading to 
additional tree damage over Magnolia Ridge Dr East, Villere St, 
and Galvez St. Another area of more extensive tree damage was 
along the corner of Villere St and Park Ave. 3 large hardwoods 
were uprooted on one property with 2 falling on a house. The 
tornado would continue to the east likely lifting momentarily as 
it crossed hwy 190. The tornado would begin again only half a mile 
later near the intersection of America and Carroll Streets. 
Sporadic mostly weak EF0 tree damage would continue from Lafitte 
St across hwy 59 and to the intersection of Clausel and Dupard 
Streets. The tornado intensified momentarily as it led to 
additional snapped and uprooted trees along Dupard, Albert, and 
Carmel St. A large 4 feet thick softwood tree was twisted at the 
base and fell on the back of a house along Lucia Ln. Sporadic 
tree damage would continue over Monterrey Dr and Soult St with 
the tornado finally lifting just before Dupre St.
