A Flood Across the Land

I was driving in my car on a two-lane highway. It was dark outside. I approached a low area in the roadway and noticed it was flooded with about a foot of water. There was a commotion as people were trying to get away. Immediately to my right, I saw a wall of water, maybe ten feet high, rushing towards us. In a panic, I quickly turned the car around and barely escaped the flood. While the flood was not extensively deep, it was destructive and covered much of the land.
