Hurricane Irene hit here in NJ. I've been up most the night. My back up battery for my sump pump failed around 2:30 AM when the power went out, and my basement began filling with water. I actually keep my books and music stuff in the basement, so as the water began rising, I moved what could.
I simply prayed. Books are just... things. So, I simply was thankful for the years I had them. As the water filled, I turned off my furnace and hot water heater, unplugged what I could, and tried to figure out how to get down to my electrical panel once the water stopped. As the water encroached upon the part of my basement where my books are, the power came back on, and my pump kicked into gear, and in about 5 minutes the water was gone. If the power though goes out again, it'll be the same thing all over again.
I've got a serious leak in my kitchen, but as long as I empty the buckets, all will be fine. I'll re-shingle and patch. I've yet to head into my attic, but I expect to find a few leaks there as well. My house is around 100 years old. It's seen this before.
