I grew up in southern NM and I remember those flash floods. I used to love those days. You could smell the rain 2 or 3 hours ahead of time. And when it started, the first rain drops would make circles on the sidewalk an inch or two in diameter.

My dad's folks lived in Duncan, AZ, just across the border from Lordsburg, NM. As a wee lad, I used to love the road between the two as about every few miles would be a sign that read "DIP." Pretty sure these were arroyos for the runoff from flash floods of this sort. It was a roller coaster ride for me. Gave me the tinglies in my tummy.
