With Wednesday's wind advisory and heavy rains in the forecast, many homeowners around the Tennessee Valley fear the sights and sounds of falling trees.

"It's happened so many times here, and a lot of people say ' Well, I would just move if I was you ' but you know, its my home," explains Carolyn Sims, as she and her husband Claude hope not for a July 15th repeat.

That's when strong storms rocked their Hedgewood Drive neighborhood, dropping numerous trees and crushing two vehicles in the process.

" I'm worried about the trees behind my house," says Claude hours prior to the storm. "Because if the winds get high about them blowing and tearing the house up."

" It's proportional to the tree I would say," speculates Arborist Sam Manzer of Big Woody's Tree Service. "So the bigger your tree, the bigger the sway is going to be and the more worried I'd be right there."

Manzer says annual check-ups by a tree expert is the safest bet in identifying a potential fall, but there are some tried and true tips, like dead limbs, which are a dead giveaway to possible trouble but there are other, more subtle signs to look for.

"Bark discoloration happens as a tree slowly starts to die or it holds water on the inside which weakens the tree tremendously," says Manzer, who categorizes dead or hollowed out trees as those most prime for a fall.

" Tap on the tree, if you hear reverberation, if it doesn't sound solid that's one way," says Manzer of determining a hollowed tree. " Another old school method is get a skinny nail, drive that in and see how much resistance you might get."

Manzer also says tree owners should take note of a bowing anywhere around the tree's trunk, saying that suggests root damage and a greater likelihood to topple over under the right conditions
