Tim's Response: You're right. A lot of folks are worried that some sort of "shit hits the fan" event will happen in September or October. Some are worried about the Jade Helm military exercise, others are concerned with biblical prophecy, still others are growing alarmed over the general direction of world events, as well as continuing bad economic trends. For whatever reasons, right now I sense more angst from the prepper/survivalist community than I have in several years.
There may be genuine statistical reasons to worry about the Fall. Historically, September and October seem to play host to an abnormally large number of bad events - the 9/11 terrorist attacks, the stock market crash of 1929, and the economic crisis of 2008, just to name a few. I don't know if this Fall will see a similar major event or not, but I will certainly be paying attention!
How should we prepare for whatever may happen this Fall? Sadly, with September now less than a month away, it is too late to do some things. There really isn't enough time to move away from the big city and set-up your homestead. But, if that is on your things to do list, don't stop working towards that goal because you're worried about this Fall. There is no guarantee something bad will happen yet. It may be sometime next year before the SHTF, or the next year, or the year after... Keep working your long-term plan.
If you do want to prepare specifically for an event within the next few months, I do have a few suggestions:
First, stockpile lots and lots of water, food, first aid & medical supplies, personal hygiene supplies, cleaning & sanitation supplies, and other useful items. If you have a fireplace or wood stove, stockpile wood for it now. Make sure you have a least a few hundred dollars in cash stuck back in a safe, well-hidden place.

Second, work on enhancing your personal and home security as much as possible in the coming weeks. Get a gun if you don't already have one, and learn to use it! Stock up on ammo. Consider replacing your easy-to-kick-in doors with heavy duty security doors. Consider installing burglar bars on your windows, and enhancing the outdoor lighting around your home. Make sure your smoke detectors are working, and get a couple of fire extinguishers if you don't already have them. Go over security plans with your family.

Third, do not skip or put-off appointments with your doctor, dentist, or eye doctor. Get those things taken care of now, just in case you can't later.
Fourth, do not skip or put-off any needed car maintenance or repairs. Get the oil changed. Inspect and fix the brakes if necessary. Service the transmission. Get new tires if you need them. Replace the battery if it is getting old. You don't want to have to deal with a broken-down vehicle in the midst of an emergency. If you can safely store some extra gas (in containers designed for that purpose), do so. Don't store gas inside your house or apartment!
Fifth, if you don't already have a bug-out location, its probably too late to buy one. Instead, figure out somewhere else you can go in an emergency - perhaps to a relative's or friend's house (somewhere away from where you are now, and away from a big city). You may even want to preposition some clothes, food, and other supplies at their house. Don't have a friend or relative you can stay with? Maybe your best bet would be camping at a national or state park, or private campground. Decide where, determine how much it will cost, and make sure you have the appropriate gear.
