Irma, getting nervous

You can't overreact, only underreact. Because of where you live I'm sure you know how a hurricane can change course at the last minute. I would take action like it's going to hit you, I was on Oahu when Iniki hit, it changed course last minute, don't trust those "I" lettered storms!!! Take care and be safe!
My wife said the same about the "I" storms
