I'm over 100 feet above sea level. I won't flood out. I would need several hundred inches at least in a day.It sounds like flooding is the biggest issue post Ian.
Not to make light of the situation but 100 years ago Florida was a gigantic swamp. Some giant channels were cut to drain it so when 18 feet storm surges send water upstream while 14" of rain send it downstream flooding is bound to happen there.
When a tropical depression got stuck over Richmond VA a few years back it got 18" of rain in about 2 hours. My home was at the top of a hill. The curb that lines the road on both sides is 6" tall. Water was falling from the sky so fast water AT THE TOP OF THE HILL was over topping the curb across the pavement. At the top of the hill!!!! Point being when Mother Nature unhurls her wrath it doesn't matter what elevation above sea level you are at.
I feel bad for the people in Florida that Ian has wiped out, but when family says "come join us, you'll love living here" I say "nah, that's ok, I'll stay here 200+ feet above sea level thank ya".
