ELI5: How does two or three feet of rainfall result in flooding so severe people are stranded on their roofs?
gpt
3 feet of rainfall 'over hundreds of square miles and varying terrain'
All the water will collect in low areas making giant puddles basically. The same way you get puddles in the road. There might have only been 2 inches of rain, bjt you can step in a puddle 5 inches deep.
