Heading out shortly to top up the tank and get couple hundred out of the ATM. My nerves are getting a little agitated. Walking with thoughts and prayers heavenward.
Water. Speaking from the Hurricane Prone Gulf of Mexico, get more water than you think you need. Not just drinking, but be sure you can flush a toilet if the power is left down in your area.
A good sealing bathtub should be full of water when it really gets close.
Some little items like that can cost little but make a couple days without power soooo much better.
Any plastic milk jugs or the like should fill your freezer with water. Lots of ice to ride through power outages without getting too warm.
I was on Guam for super typhoon Pamela, and having stashed water and food, I was in good shape.
