How does 10 inches of rainfall cause extreme flooding like what we are seeing in Kentucky?
In: 9091
10 inches of rain might not sound like a lot, but it actually is. To put it into perspective, 10 inches of rainfall equates to roughly 56 gallons of water for every square yard of land it falls on, which is about ~~3 million~~ 173 million gallons of water per square mile.
Edit: Screwed my math up. There are roughly 3 million *square yards* in a square mile, and at 56 gallons each it’s more like 173 million gallons.
