My sole experience with a natural disaster was a large earthquake in a small central CA town. Water, sewer, and natural gas out, electricity restored in a short time. Many homes knocked flat, or at least off of their foundations, downtown area destroyed. Within hours water buffaloes from a nearby Naval Air Station arrived, within 12 or so hours lots of portapotties (plus many almost immediately from a local business), within 24 hours more canned and bottled water than could be used from a beer brewery in southern CA, and lots of eatables from a variety of sources. Within a few days a huge circus tent, used to feed folks via the Red Cross (one of the few good things I have to say about them). Within a week or so numerous single wide mobile homes from FEMA (one of the few good things I have to say about them also). Within a week or so every natural gas worker PG&E had in the state arrived to completely replace the underground NG lines (in places, the old gas lines were completely rotted away, the gas had been flowing thru holes in the dirt for years. The dirt was so impregnated with gas that it would burn!) I know that this isn't exactly what happened with Katrina and other hurricanes, I guess we were lucky.

Given our lifestyle and the capabilities of our home on wheels, I figure we have a couple weeks worth of water if we watch it, and by tightening our belts a few notches from time to time, probably that much food. After that, we are gonna need some help...

We have always planned for 1 month, due to the potential for a disaster to occur during Winter.

Be prepared for even longer, look at the people who lost everything in a hurricane or tornade and had to relocate becaue there was no home to return to. You have to rent an apartment or hotel or somehting and live there.
Short term can even go a week, we had just moved before hurricane Katrina came through and knocked power lines down in our city. Out old neighborhood was without power for 8 days and this is in columbus OH, quite far from hurricane territory.

It's really a dutch thing. The flooding caused by the sea affects land which is mostly higher than the sea level. So most of the flood water will just run back to sea, naturally. The flooding caused by rivers, will effect land which is deeper than the sea. Which means the dykzones will act like a badtubes. It takes a full day to pump 1 cm...

The dyked areas fill up like bathtubs when the rivers overflow.
OK, I understand.

Thanks.

Look at how your local services have responded in the past. That can help you get somewhat of a benchmark.

How well folks adapt depend on several things:

How well is one prepped:
If you have enough water for a week. Then a week isn't so bad. If you have enough water for a day. A week is way too long...

Previous experience:
Being without power for one day for some of the younglings is a hardship. Those of us who have gone for a week or more, have a different perspective.

Attitude:
A bad attitude makes everything seem longer. Remember the old adage; "time flies when you're having fun".

"..."time flies when you're having fun"..."

Very true. Which makes having something "fun" along all that more important. Books, deck of cards, toys/games for the kids, etc...

Most things? 1-12 hours, 24 at the outside. Storms, powerouts, etc

Thats why I posted a recent storm that caused an 8 day power outage in the major city. Our power company sent help to NA as the storm went across land so when it finally hit here they were short staffed.

Kids like breaking out the camping equipment, hanging lanterns from the ceiling fan in the living room just like they would be from a tent, etc.
