Going to school in a hurricane-prone state? That sounds like a great idea!
Seriously I refuse to live anywhere that wouldn't remain well above sea level even if you melted every ice crystal on earth. If the universe wants to natural disaster me to death it's gonna have to go the extra million miles and drop an asteroid on me.
Helene ended up around the southern tip of Illinois and Indiana so uh, yeah, everything from the Gulf to one state south of the Great lakes is hurricane territory now.
Well I guess we can't go to universities in the eastern half of the US. And not in the middle either (tornadoes), and not in the west either (wildfires). Should we all move to Wyoming? This Lemming seems to know what's best for us 340 million Americans. Surely we can all fit in Wyoming. It'll be a glorious utopia!
If a 400 sq mi area gets 2 ft of rain and there's a low valley area surrounded mostly by mountains, the water will drain down the mountainsides to the valley. It's like a big bowl. The water that settles in the valley will be more than 2 ft because of the rest of the runoff from even higher elevations
That's right: usually. Sometimes no. Or sometimes the volume of water only slowly drains away (like some rivers move extremely slowly and it's almost as if it's not moving at all). If it takes 3 days for the water in the normally filled river to move 1 mile, even if it takes 2 days with the flooded valley to drain instead of 3, that's still 2 days of floods.
Imagine you drop a bunched up shirt onto the floor. If you look, you'll see that there are lower spots surrounded on all sides of high spots. Terrain irl is not so different from that in spots. Hope this helps explain :)
And don't forget that quite a lot of the rivers are likely clogged with downed trees, landslides, and other debris, further showing the draining process.
You should learn a little geography. NC is a very wide state. Most of it hasn't been prone to hurricanes. The coast gets hit every few years with a decent one, but it's been over 30 years since one came anywhere close to that far inland with more than the power of a heavy storm.
