Basically if you live somewhere in a flood plain (where it rains a lot) you might not want to be there anywhere on earth

 If you study carefully what is happening in Texas, Oklahoma, North Carolina and New Mexico you begin to see that living or visiting a flood plain isn't a good idea right now.

For example, (this is a real life experience) I was driving my 1968 Camaro out in the desert near Old Woman Springs up on  Yucca Mesa in Southern California (which has a lot of desert areas). So, this was 1969 and I would have been 21 years old. And I was tooling alone in my Camaro and suddenly I"m looking at a 3 foot or more wall of water coming at me out of the mountains nearby. The desert itself was okay but the problem was the Rain and clouds in the mountains right next to me had obviously been raining even though it was clear and dry where I was. So, out of the mountains (BIG BEAR and Mt. San Gorgonio comes a wall of water over 3 feet high. And I immediately knew this was likely going to kill me and flip my car over and over across the desert because of the nature of moving water like that.

So, I only had 1/2 a block or less before that wall of water hit my 1968 Camaro so I burned rubber in turning around at 30 or 40 miles per hour and left there as fast as I could.

However, if that water had NOT been coming at me head on I wouldn't have survived this because I wouldn't have had anywhere to go to escape in my car. 

But, luckily it was coming head on and I had a way to escape it.

So, when flash flooding comes you need a tree or a roof to escape onto otherwise  you might be dead and drowned.

You might say: "Oh. I'm a good swimmer. I will be okay."

But, that isn't the problem. The problem is underwater obstacles like branches, trees, bushes, pieces of lumber or metal. It's sort of like a hurricane when pieces of signs and buildings are flying through the air only on top of or under the water.

So, your best bet is to climb on top of a roof or up a tree (depending upon how deep this flood is and how long it's going to last.

For example, in 1862 the Sacramento River was 20 miles wide and people were on top of barns and in trees between Sacramento and Redding who were in the path of this gigantic flood. And historically this type of flood happens every 150 to 300 years or so. So, the last one was in 1862. When will the next one be?
