Have a back-to-the-future party while you're waiting it out.
Think books, board games, card games, art activities (small ones - you won't have much room if you have to wait it out in the basement), guessing games, hobbies that don't take up much room, talking, telling stories together, singing. If you can find some hand-held fans, get them. Don't forget flashlights - and candles if you can use them safely.
I don't know what they did 150 years ago (that would have been 1851, I think) but houses back then did have storm cellars, so maybe they did those things, too. I know that fifty to sixty years ago in upstate New York we waited out hurricanes in our basement and did the things I've listed above. I remember my parents being very reassuring, so add courage and reassurance to your list of things to stock up on, Mama!
