Lmao. I live in FL and in my experience, no one I know avoids showering or using the bathroom. I know my family and I had done showered, etc during storms and hurricanes. Not saying it won't come true but when you live a state that goes has days on end of storms, life has go on. What I did hear was not to use the faucet because you can get shock from the lightning if it strikes your home. I still use it away: those dishes are not going to wash themselves.
I even take my dogs out to pee during a hurricane. The patch of grass is 5 feet from the front door and you just got to look for that short 'calm' in between the crazy wind and rain.
I think we Floridians are so used to this by now. We have the occasional wandering gator, iguanas, Hialeah...
