I just got home from one of the most severe rainstorms in my area in a long time, and some thoughts occured to me:

Today, we had such massive rain and hail that flash flooding occured everywhere you could imagine, stalling cars left and right; we live in a landlocked prarie, and though such weather is unusual, when it happens the result is pretty similar to dumping a cup of water on a tabletop, and as experienced winter drivers our citizens may be, they have no clue how not to stall in deep water, and end up stalling whole strings of car at a time.

Some concerns came to mind:

To what degree :)o ) would you obey traffic laws when the storm struck and stranded you on the road, assuming your vehicle can escape? Being the agricultural-oriented province we live in, trucks and SUVs were going over medians left and right, and what used to be neatly manicured grass is now mostly a mess of mud and mangled sod.

Another thing that came to mind is, would you bug out of your vehicle if it was disabled in some way, but stationary? I don't mean getting out if it before it gets dragged into the river, but more like leaving it behind, along with firearms you have in it, because the engine is stalled from deep water, or snow keeps it from moving at all?

Another thing is that drivers here aren't known to be the greatest in the country; twice today during the storm, for no apparent reason, the car in front of us refused to move along with the crawling traffic, and backed right up to our bumper, effectively boxing us in and giving us rude hand gestures. As we backed up a bit to get out, he promptly backed up more, until we decided that we were getting out by backing out instead. Though there was no apparent rush, I'm still trying to figure out what possessed this person to try whatever he was trying. I suppose if it came down to it, SUV > Fiberglass Chrysler any day. ;)

After this rainstorm, it occured to me that my Toyota 4Runner is probably as tactical of a car as need be, and would probably serve me well in an emergency despite its high fuel demands...
 
I've run into the same sort of problem at low-water crossings in Texas. (The DOT installs posts with depths marked on them.) Sedan drivers can't get through two feet of water, but my Toyota 4WD PU has no trouble. The twits get upset at me when I don't "wait my turn"! (With my air intake at the top of the carburetor, I can go through water that's just above the headlights. Stock, I couldn't.)

I guess the best defense, overall, is to know where are the trouble spots in your area and avoid them until the aftermath problems have settled down.

At home, I run the Light Truck 7.00x15 Mud/Snow tires, so I pretty much go wherever I want to...

Wholeheartedly agree on the Toyota 4WD. You can ride in them while the guys in the broken down M113 are trying to get the maintenance team to come out with more bailing wire and bubble gum to patch things together long enough to get it back to Ft. Someplace.:D
 
You may be able to drive through water up to your headlights but I've heard several times that under the right conditions water as shallow as two inches can displace a full-sized pickup. That kind of stuff happens all the time in the Houston area. I don't live in that area anymore but I've definitely made some white-knuckle drives through some fairly deep water flowing across the road from overflown creeks and rivers. So far the Xterra hasn't ever been displaced but I don't have much desire to make any more of those drives.

We get floods around here about once yearly.. so like Art I drive a 4x4 PU so I can still get around (though it's not a 'yota). I don't have a snorkel, but my truck sits fairly high. After a few water crossings, it's a good idea to drain the differentials and the T-case -- water tends to sneak in through the vent tubes, and it doesn't make a good lubricant. :D

It IS funny watching people trying to plow through the water in their Ford Tauruses (taurii?). People don't realize that the faster they hit the water at, the more water is gonna go up over the hood.. :rolleyes:

But most of the flooding we get around here is standing water -- rushing water is a major no-no to drive through, it CAN pull you off the road very easily. Once you're over the edge, you're just more work for the Coast Guard boys (or whomever does this kinda thing inland) to try and rescue.

Or you could take and go pro-active by extending your vents with a few feet of tubing (fuel line works great for this)..

So, you may ask, why would someone want to extend the vents on their rig? Answer > When you dunk a warm axle housing under cold water, the air inside will contract, which will cause the air to try 'n pull water in past the axle seals. Also, by extending them, you ensure that the breather itself doesn't go under the water. The stock breather is basically just a one-way valve, allowing excess pressure to vent out..

On Toyotas, for example, you can remove your stock diff vents (the tranny and transfer case should have a vent, too) and install what Toyota calls "a union" (I can't remember the part #; just talk to the parts guy at the Stealership, he should know what I'm talking about).. You just unscrew the vent, screw on the new "union", slap on a few feet of fuel line (vacuum hose works as well), secure with a hose clamp, and then run the other end of the hose to someplace that is high 'n dry.. You can also add a fuel filter to the end of the hose for a little added protection.. ;)

Mind if I ask what you drive?
 
Hey, Glamdring- I really don't know, I've never owned anything other than a Toyota. What brand of rig do you own?

Oh, yeah, I currently drive a fairly stock '96 Toyota Tacoma 4x4, with future plans on acquiring a 1985 Toyota as my next project.

Here's the Toyota part # for that "union" that I mentioned earlier..

part # 90404-51026

Price? My dealer wanted about 4 bucks for one. ;)

** EDIT: Here's a good write-up (for all those 'Yota owners out there in THR Land) about extending your axle vents..

Personal opinion: When selecting some sort of "go anywhere" vehicle, take a look from the rear. Do the lower shock absorber mounts extend below the axle housing? If so, it's a bad design for rocky-offroad travel...

DigMe: 2 inches of water? Sounds like hydroplaning to me. That's a speed function, not a design matter. Hydroplaning can occur with merely a thick film of water on smooth pavement.

Some designs are more drown-proof than others. Some distributor caps are sealed by O-rings with the cap screwed on tightly. The rubber caps over the spark plugs, coil and distributor fit very tightly.

WD 40 is a Good Thing to get a drownout revived and running. :)

Ah, my bad! It's two feet, not two inches!

Most vehicles will become buoyant in two feet of water or less. People who have previously driven successfully through a flooded low-water crossing often do not recognize that an increase of an inch or so in the water level may be all it takes to tip the balance of buoyancy against them!

Standing water . . . maybe OK, as long as you KNOW the depth. (And I hope your door seals are sound.)

But in the low water crossings around here (Austin, TX area) you'll be getting current, and a lot of it. Trying to cross that in a Toyota or any other pickup/SUV would be a really, really, bad idea. :what:
 
Years ago I was at ground zero during hurrican andrew in florida and I can tell you in the days following it was like a combat zone with looting and basic bad behavior...As a rul, I did not stop for anyone or anything if it could be avoided and when i did it was with extreme caution and always was on alert.

As for the water crissing thing, I now live in AZ where we have runnign washes after rain storms and it never fails, some orong will try to cross it in a POS sedan and get stuck halfway.
 
I've spent a lot of time over the past 25 years or so driving the beaches of the Outer Banks of N.C. (in a Subaru no less) and it doesn't take much running water to move a vehicle sideways - a foot will do it depending on the speed of the water, the weight of the vehicle and the diameter of the wheels and tires.

I floated my '86 Subaru wagon(dual-range trans, armored exhaust, adjustable rear shocks, skid plates, etc.) many times and never stalled it or got the carpets wet, but I wasn't playing in the running surf either. I haven't pushed my '02 Forester very hard yet, but does okay in the deep soft sand even with an automatic.

Anyway, another thing to remember about really deep water is that your fan blade will pull itself into the back of the radiator and cut it all to heck. The serious guys mount a cutoff switch on the dash to disable the fan.

John...I'm staying with the car as long as it's safe.
 
HankB, I have discovered that it gets very dark when crossing Terlingua Creek with water over the headlights. My witnessing buddy and his wife were rather concerned when the taillights went under.

But I made it. :D

I crossed the Rio Grande at Lajitas, one night, and got the headlights under water.

Neither event was actually planned. :D:D:D

What saves me in high water is that I don't use the stock air intake to the carburetor. The stock "snout" takes air from beside the left headlight.

Hey Art, have you ever considered getting one of those Safari snorkels? Ya' know, the ones sold by ARB?

It might just save you from hydrolockin' one of them thar 22R's.. :neener:
 
Well, er, ah, it seems the water was just a wee tad deeper than I expected. I just really don't want to drive through water any deeper than past adventures, thank you. :D

(There are some people who are a skoshi bit nervous about riding with me...)

The deal is, I'm running a Weber carb; it sits atop an adaptor block and the air intake is pretty close to the hood. It's probably a foot higher than the headlights.

The Wasburn Tunnel in Pasadena TX is NOT a good place to be when a flash flood hits. I told the Relative driving - me apassenger it was not a good idea. I just sat on the top of VW looking Volvo...and waited.

Dallas TX is another place when flash flood or snow hits one needs to just pull over and wait. I just thought folks her around could not drive. I used the rental cars, Buick and Caprices to escape to Harry Hines Blvd, and watch the show. :p

VW Karman Gia's and Beetles with the solid bottom will float one across the rising creeks and such. Hard to steer...I don't think the officer was real happy when we made it and could not...granted the cherry on top had been flashing for a while tho. What is the statute of limitations in OK anyway? :p

Around my stomping grounds-
Serious woods with streams and such, the older vehicles with some tweaking like Art and Shuey suggest are good to go. City streets, I know where to avoid and don't go there. I have a small 11 yr truck, 2 wd, I have tested and know its limits. Not to proud to sit tight and wait.

I have used a Truck like Art's or OLD '70's Bronco...folks r-e-a-l concerned about me...the one's waiting were concerned the ones watching this more concerned , and the passenger , real wide - eyed.

Maybe just the sight of water halfway up the windshield, me coming down the small river that once was a creek, hanging a hard left going through the fence with Jimi Hendrix cranked up and not stopping until I hit high ground had something to do with it. I said I could I get the daughter to safety...open door and beer bottles float out...they do dat with 8" of water in the floorboard...oops. :)

I think I could ride with Art and be fine...:D
