I just saw this thread and as someone that lives at the beach and has had to evacuate 3 times in 10 years, audio gear is the last thing I pack up. You take your home files, medical documents, insurance doc's, financials docs, external hard drives ( and laptop) that contain information, like home documents, pictures other personal files, passports, money if you have any stored, medicine you need, yes possible music,, pet and its supplies. Then it's clothes you could need for an extended stay, and items that could be destroyed by moisture, if you have room in your vehicles ( we take both) like my guitars (only that go, and a few wall art hangings), a camera for documenting what you come back to and some of the wife's jewellery, phone charger, fire extinguisher, flashlights and batteries, water ( as much as you have room for) and if room some food stuffs ( canned, dry food). Most stuff is covered by special insurance ( IF YOU HAVE IT) riders away from basic home owners or flood insurance. Special insurance riders can cover stuff like musical instruments, art work, jewelry, audio equipment. And most important, clear recent pictures of your inside and outside of your home including the protection you provided your home, shutters, sandbags etc.. and SN's for any electronic devices you own ( TV's, audio equipment). Cause when you come home you might find this around your home , yes my home , thankfully we were 1 1/2 ft higher than the storm surge.
