I used to be a volunteer firefighter in a small community in AZ where wildland fires were always a threat in the summer.
I had a large plastic storage container in my garage with a full change of clothes (don't forget extra underwear and socks!),a sturdy pair of boots, spare personal items such as toothbrush, toothpaste, etc., a container of moist towelettes for a "quick" cleanup, a blanket, pillow, a supply of cat food, dog food and treats in zipper bags and of course some health bars for myself! I kept the "soft" items in zipper bags with the air squeezed out to make them more compressed, but also to keep them clean and dry. Of course I had spare food and water bowls for my pets pre-packed. Don't forget to keep a few gallons of bottled water on hand to "grab and go" if need be. We can all go without food, but NEVER without water. My "rule of thumb" was enough for 5 days for all evacuees INCLUDING pets.
I kept this emergency evac kit in the garage for quick and easy access in the event of an emergency. Keep everything you plan to take in the same area. Time will be your best friend or your worst enemy!
While it sounds a little "over the top", keep your most recent bank statement and a spare checkbook in your evacuation kit. You may need proof of your financial status! Keep a list of the mortgage company, car loan, etc. with account numbers and PHONE NUMBERS in the kit as well. You never know how long you'll be stranded and without access to your accounts. Remember what happened with Katrina!
If you have the luxury of time (and space in your vehicle) bring your essential documents, pictures, laptop or the CPU of your computer, (THAT'S where all the important stuff is)and forget about the keyboard, monitor and printer!
Speaking of your vehicle, when in your area's "danger season", whether hurricane or forest fires, make sure you keep your gas tank full in the event of an evacuation.
HAVE A PLAN!!! Know where you're going to go and have several alternate routes to get to a safe area. Make sure you have area maps in your vehicle.
Without overstating the obvious, bring your cell phone AND the charger for use in your vehicle. You may not have service in all areas at all times, but at least you have the option! MANY cell phones have GPS built in, so even if you can't contact loved ones of your status they MAY be able to have authorities locate your location by the GPS tracking signal.
Okay... I think I've covered the most important stuff. LOL!
I hope none of you need to use these suggestions, but if you DO, at least you'll be prepared.
