Tornado Shelter – Part 2

This is some lovely rotating clouds we saw from our front porch during a severe thunderstorm. Fortunately the rotating never organized into anything, but it sure makes you think.

The roof needed to be made in advance and so we made it from 2 sheets of 3/4 inch plywood. These were glued together and attached to a frame of 2X4s.If we decide to upgrade to an F5 suitable shelter we will add 1/4 inch steel sheets. I don’t think we’ll bother though. The cost would be huge and the risk, while not zero, is extremely low.

The space for the shelter is here under the main beam and near the stairs. Naturally Klinger supervises everything,

We have a very high water table anyway and with heavy rain we get a lot of water. If the sump pump fails the basement fills with water to the height of the black on the bricks. So the flooring has a one inch space for water to flow to the sump pump. During a severe thunderstorm, a space like this can swiftly fill with water from inches of rainfall so we have to plan on being wet. Because of the wet, the bottom most layer and everything that touches walls is made from treated “preserved wood foundation material” lumber. We have also purchased an emergency back up sump pump that will run on DC power since any severe weather will likely mean the electricity is out. There will be a deep cycle marine battery in the space. We will also have lights from the battery.

We originally were planning on bracing the roof into the beam of the house itself. But according to FEMA it’s better for the box to be self contained and not attached to the house in case the house gets moved off its foundation. So the box frame is bolted to the concrete with special 1/2 inch concrete anchors at six points on the floor and four on the roof where it attaches to the cinderblock wall that will act as the fourth wall. Each concrete anchor can take 1000 pounds of force with ten bolts we have 10,000 pounds. It’s not going anywhere any time soon. It would hold very nicely for an F2, F3, the kind typically found in Manitoba) and probably an F4. It might even be good enough for an F5 providing the tornado passed over very quickly and didn’t sit on us churning, since we are also below ground level.

Now the roof is in. It’s all framed with temporary frames and bolts until the main interior framing is completed. I can’t say we worked all that hard. We took lots of breaks, had a rather leisurely dinnerĀ and we didn’t start until after noon. Plus we had an afternoon nap. We finished to this stage by 9:00 pm.

Sirens Sounding

We are sitting in a Milledgeville restaurant in downtown Milledgeville called the Local Yolkal. I woke up and saw an approaching storm system and it was aimed right at our little, totally vulnerable, camper. We were also under a tornado watch. The storm seemed to me to be increasing in intensity and I could see the beginning of the radar hook. So we decided to abandon our home and move to a safer location in downtown Milledgeville where the buildings are sturdy and there are basements. Just as we entered the cafe the sirens began to sound. The locals are calmly alert and ready. One fellow told us to move indoors now and suggested the Local Yolkal for breakfast and storm shelter. The waitress told us the place has a shelter big enough for all the staff and guests so if it gets ugly we can move downstairs. And so we now wait out the tornado. On its current track the storm will go between our present location and the trailer to the north. The biggest problem we may face is getting home if it damages stuff on the highway.

This challenging weather is why America will never be defeated. There is nothing any ISIS or Al Qaeda can produce that is as bad as what Americans regularly deal with from Mother Nature. Listen, react, take shelter, wait and then deal with it when its done.

Epilogue: The storm broke into two cells and one went between the town and the campground. The cell with the tornado passed to the southwest of us, veering that direction as these storms so often do. We saw a lot of heavy rain and a lot of wind but that’s all. Locals watched closely but made no move to head to the shelter so we just watched as well. There are some reports of an eighteen wheeler blown over and some reports of minor damage but not affecting us here in the restaurant.

We returned to our trailer to find the area littered with pine needles and pine cones and lots of running water on the hills and in the ditches, but otherwise no damage. Score one for Mother Nature.
