My edc bag was valuable. It had phone numbers of all of my family, a comb to fix my kids' soaking hair, mints to bribe the kids, keys, knife, etc. I didn't have to spend minutes looking for all my pocket stuff. My bug out bag, on the other hand, needs work. It was so heavy, and soaking wet, I thought my elderly neighbor was going to hurt himself as I handed it down the ladder. In the future, I will break it into two bags, with the heavier stuff like food spread out. Also, I'll work to make it more waterproof. I suspect that many disasters come with rain. Hopefully, the small lessons I learned are valuable

Waiting for the blog spotter Humblegunner.
Lots of shelters in Moore.
Wait for it...Almost in range...Wait for it...Almost in range...Wait for it...Almost in range..Wait fo......
Your name came up....
Based on some stories I’ve seen about doors being sucked open, you might also consider beefing up the latch.
Kartographer has the one and only dispensation granted by this department as regards Prepper Material.
It has two chain locks on it.... can’t really see them in that picture. It’s 8 x 8 .... 7 foot tall inside. Well stocked :)
Hopefully, you have another entrance if that wall falls on the door.
I like the reinforcing tubes on the door.
If you’re handy, I look at adding another tube or angle iron along the latch side, and making sure the chains are welded/bolted solidly through the tube.
Got involved in a discussion with a neighbor about political matters and somehow we ended up with the prepper issue. He and his wife both have professional jobs, make and spend a lot of money and have no children. He stated he knew they wouldn’t have to worry about having anything extra because he knew all the neighbors would pitch in and share what they had because he and his wife “were so busy they just didn’t have time to deal with such things”.
All the other families on our block have small children, stay-at-home moms and single incomes. They are all filling their own Obama Closet as best they can, a little at a time. I certainly would help those folks if I could but I think after listening to me for a while now realizes he and his wife would largely be on their own.
That wall is north of the cellar. Typically the stuff gets blown north... but nope... that’s the only entrance. In this part of the country you’re suppose to register these cellars so first responders know where to look. My family knows where to look too. But that’s why you stock it with batteries, battery powered radio and light, etc etc... in case you gotta be there a day or two.
Also... that door is really heavy. It’s made of some pretty thick sheet metal welded to angle iron. That green pole holding it open is spring loaded at the bottom, or one person wouldn’t ever get it open by themselves.
I did a (very rough) calculation.
A quick search indicates you could have a delta pressure of about 100 millibars due to the tornado. That’s about 1.5 pounds per square inch. (that’s an extreme assumption but possible).
If the door is 2 ft by 6 feet, that’s 1.5 x 24 x 72 = 2592 pounds force.
Did they get tore up?
I don’t blame you for wanting to be underground in your area. Where I’m at, storm runoff could quickly flood an underground shelter. Something like the shelter you pictured may be the only option.
Yep.... flooding isn’t an issue for me, so I’m good there. You know... Moore is 4 miles east of me. At the hospital over there, it’s 3 stories tall. There was a car on top of it that had been down the street a ways. Can you imagine being in one of those above ground safe rooms and having it hit by a flying Toyota? LOL
I’m sure it’s far better than being only in a wood frame building but no substitute for being below grade level.
Hopefully some folks will look closely at the aftermath of the Moore event and study what worked and what didn’t. I see on my local tv you guys are back in the potential risk area so be safe. We get it here in Indiana tomorrow.
You be safe too....
Not considering wet weather is an easy mistake to make. As we learned in the Corps, if it ain’t raining, you ain’t training.
We drove thru the devastation last Thursday and again yesterday. That area looked like a war zone. Some cars looked like they had been in a junkyard for years and dropped next to IH 35. All the paint was gone and there was no way to ID the make or model.
Give me something underground,
Yeah.... it’s crazy ain’t it?
They are rated to survive an F5.... so they say. I think you’d want to take your hearin’ aids out while it blew threw.. :)
FYI tornados actually cannot “suck” doors open. They can only reduce the pressure on the outside, so the force of the air pressure cannot exceed the differential between the air in the shelter and the lower air pressure in the funnel. In reality the shelter is forcing the doer open by its air pressure.
Just the engineer in me ...
Enjoy your day.
You never know whats really important. This is my family after my Grandmothers death from the F5 in Tuscaloosa.
By the way, we got it back! FREEPERS! They don’t know what we’re made of.
Out at the old family place, the cellar was away from the house and trees. Here, I want one but the water table is too high.
Wasn’t that the calculation I showed?
The 100 mb differential pressure between the inside of the vortex and the shelter chamber?
Of course we totally neglected any pressure equalization that would occur because the door is likely poorly sealed.
But it does give a bit of insight into the forces acting.
Or what we call in Indiana “farmer math”
The door seals pretty good actually. I mean it won’t rain in and water won’t run in it. But it has two 4 inch air vents in the cellar. PVC pipe inside those tin vent covers.
I think I have one neighbor who is preparing. His bug out plan includes a rebuilt moped he plans to use to ride out of dodge.
I’m pretty sure Im on my own.
Excellent fuel economy but poor range (unless fuel tank upsized) and lacking in speed.
I would consider a dirt bike as an option. A moped can’t even go off road.
Yes, it was hard to imagine what the news footage had until we saw it in person. I remember the destruction from the Jarrell tornado that ended up in Cedar Park and Lakeway.
I wish I could have one of those but our water table is way too high.
I am exhausted. Any one else have experience with that NOAA weather emergency radio linked in the story? Combo flashlight and rechargeable 5 ways including hand crank and solar charging?
Your math was fine. Only ‘protesting’ the use of the verb “suck”. ;-)
That’s funny about the moped. I have my oldest grandson’s scooter I could use but I think the battery charge only lasts for half an hour. Considering our traffic when we have to evac for a hurricane, that would get me almost over to the highway.
Now that you mention it, I have the rectangle one that’s about the size of a beer can. I got it earlier this year but since then, have been focusing on gardening. With all the chances for storms we’ve had this week, I should know what this device can handle. Will make a point of working with it and let you know.
This one is Microlink FR160 by Eton: http://www.amazon.com/NFR160WXB-Microlink-Self-Powered-Weather-Flashlight/dp/B001QTXKB0/ref=pd_sim_sbs_e_2
solar and crank powered
USB cell phone charger (check comments on the link about this)
No batteries needed.
Wow, that looks strong to start with.
For which I am eternally grateful!
