Charlotte's annual rainfall is significantly less than Houston's. And it's not just annual rainfall that matters. How it arrives also matters. Do they get 8 inch downpours like we had Wednesday without any flooding?
I have lived in both Houston and Orlando area. Yes Orlando does give heavy downpours in a short time span but the difference comes down to the soil. Orlando and Florida in general is all sand and porous limestone base soil. The water get absorbed into the ground far easier and faster than the clay soil in Houston. That does create another issue of sinkholes in Florida that we really don't have to deal with here, but in relation to flooding it helps them tremendously.
