The first confirmed death attributed to Tropical Storm Isaac in Louisiana was reported in Vermilon Parish.
Sheriff Mike Couvillon says a 36-year-old man had gone to help two friends move a vehicle from under a tree to prepare for Isaac on Tuesday, and fell to his death after climbing 18 feet up the tree.
Deputies don't know why Carlos Medellin-Guillen of Erath climbed the tree.
He was identified Wednesday after his family was notified.
The accident occurred Tuesday evening shortly before Isaac made landfall to the east on the Louisiana coast.
A 47-year-old man who went jetting Monday on a water-scooter near the Alabama-Florida state line is still missing. The Coast Guard in Mobile says it searched for him Wednesday.
