Three times I have been witness to flash floods.Once while under the water dredging,and had my dredge tied off hard and fast(last time I ever did that)The other two I was in the desert calm clear hot days.Was in the pickup on the first one and seen the black clouds and rain in the mountains I was headed to.I turned around since I really didnt want to work in the rain,and risk getting lightning struck.Upon my return to a wash that was dry on my initial crossing,I came up on it as a RAGING river.There was no way I was going to risk trying to cross,and 6 hours later when the water receded the road was completely gone(a 5' drop off!)I had a booger of a time finding a place down wash to cross....after two flat tires from driving over sage brush.The second time I was walking up a dry wash with high banks,checking coyote traps.I heard an ominous roar that was getting closer,so I climbed out of the wash to see if I could see what it was....saved my life!!!
