bellababy,
FANTASTIC !!
That list looks a LOT like mine, since I live on the Gulf Coast,
and the Wind gets up a little, occasionally.

I specially liked your inclusion of Paper Plates and Utensils.
During our Hurricane Season, I have what I call a "
Go Bag".
It's a spare soft Duffel type bag, which I have a complete
set of Clothes, Toilet Articles and stuff in it, for me. Just enough
for a few days away from home, in case we need to evacuate.
All I have to do it just pick it up and throw it in the Vehicle.
But, you and ArmaniMan mentioned a Crate/Carrier...
Many people use them regularly, and I have one, actually, it's
big enough for both my guys, save that they never get in it.
It just sets in the Utility Room open, for them to occasionally stash
a Treat in !
The thought being, it's a great Container for our Animal's stuff,
if they aren't in it when you go. I usually just Harness and Leash
my guys in the seat of the Car, I have two leash's that are permanently
attached to the back//bottom of the Car-seats, where we can easily
just snap them in safely.
But just as a start here, here's a list of things you could shove into
a Crate, where they would be covered for a day or two.
Things to stuff in the Carrier/Crate for your Animals: Leashes, short and long. Harness, Collars, with ID and Inoculation Tags, Food, bag or box, Bowls, Water Container, sealable w/lid, Towels, just in case of standing water or Rain. Covers, Sweater, Rain Coat, warm stuff. Toys, Poop Bags, Newspaper, Potty Pad, & Your Emergency Envelope !
Can you think of anything else they'd need ?
