My bathrooms are on the outside wall...so I'll forget about that solution.
Something I read a long time ago is that if people have to leave their homes on a moment's notice, they should take their insurance policies, check books, cash, medications, canned food and water with them. Same for pets.
But, sometimes when disasters hits, people are not at home! About 10 years ago we had a severe hail storm and, of course, I was on the road. The hail was so large I could not get out of my truck and run into restaurant in front of me.I sat there hoping hail would not break the windows and watched as roof lights and side mirrors were destroyed. After storm my vehicle looked like it was beat with hammers! My husband's new car looked like it was in a demolition derby.
That day the sky was green, yellow and black and I didn't want to leave the house. I felt in my bones something bad was going to happen, but my husband needed something and talked me into going out. I'll never do that again!The tile roof on our house was damaged but, fortunately, we had tile left over from construction of house. My neighbors were not so fortunate...some had hugh holes in their roofs and the hail and rain just poured in.My dogs were in their covered kennel and I found them glued to the insides of their dog houses. They were scared, but okay.
