Good thread for people living in low to medium humidity climates that receives a blistering heat wave...but for native floridians down here we got a handle on the heat, but what we mostly worry about is somebody pissing off 'THOR' even on a clear day! When you hear rumblings and thunder way out there, you better give the man some respect.
Hear, hear. The same goes for Georgia.
Speaking of lightning, we found out what took the main strike referenced
here. It was an oak tree, roughly 100 feet tall, situated in between our house and our neighbor's. Looking at its scars tells a heck of a story.
The bolt hit at the highest branch, and split the oak apart all the way down as it went, tearing away long strips of bark as it traveled down the tree. When the bolt reached the thickest part of the trunk near the ground, the water in the tree was instantly heated and vaporized, causing the trunk to rapidly expand outward, with enough force to split the trunk in several places. That sudden expansion shredded the bark, blowing it away from the tree in a section about 10 feet tall, circling almost completely around the tree. As the bolt kept going down into the roots, it blew out several of those as well, making furrowed trenches in the ground that radiate out from the base of the tree. In a few spots, there are char marks next to the ground where the bark was burned away when the bolt went into the roots. Luckily, it was raining so hard, the burn didn't last long enough to catch any of the ground cover on fire.
One shard of the exploded bark came down hard enough that it was driven into the ground, sticking up like a little gravestone about 20 feet in front of the tree (visible below). The furthest-flung piece of bark we found was a good 80 feet away, on the opposite side of our driveway.
All of this happened in a fraction of a second.
It's a shame in a way, because this was an otherwise perfectly healthy and strong tree. We're really sorry to see it damaged so badly that it has to come down, but there are several major vertical splits in the trunk that just can't be fixed. That, plus the stripped bark and severe root damage only hinted at by the burns and blowouts in the ground would pretty much seal its fate, even if we were to leave it standing. An arborist came out to check it, and said he thinks it's enough of a hazard, he may even try to get a crew together to bring it down over the weekend, before the weather here gets turbulent again.
On the other hand, the height, presence, and strength of that tree pretty much saved two, and possibly three houses from
major damage. So our little group of neighbors certainly appreciates its stoic sacrifice.
As much as the heat sucks, we can deal with it. The power of lightning though, is concentrated viciousness on an unreal scale.
Be safe out there!
