If by “packed up” you mean taking every possible item of value, I agree. Important papers, investment certificates, cash, coins, jewelry, computers, video and audio equipment, movie and music discs, photos, etc. Otherwise, weather evacuations end up making you part of wealth redistribution.
I think you would be better off leaving your large sums of cash, expensive jewelry etc. in a safety deposit box. You could be an easy target leaving since the bad guys know you will be taking valuables with you. The bank’s vault should withstand a hurricane.
