Tell that to us here in eastern NC whose homes are underwater and don’t live on the Outer Banks and are in places that don’t typically flood. We have steady to heavy rain for 32 hours straight and still a few more hours to go. 6 hours ago we had 17 inches of rain... I guess that’s a plain old heavy rain event in your book. Along with the thousands of huge trees, hardwoods as well as pines that have come down.
TS Allison visited Houston in 2001, left and then returned. Caught under a high pressure system she dumped 40 inches of rain on the city. The 610 loop around the city acted as a giant bowl. When the water finally drained on the interstate, they found 18 wheelers two deep that had been totally buried under water. Called the 100 year flood. Didn’t think it would ever quit raining. Some memories just never go away.
