Above is the radar image from moments ago along I-10 from Tucson, AZ to Wilcox, NM.

Given this is the desert, this is the most dangerous flash flood situation I have seen in a while. Both radar and satellite cloud top temperatures (see arrow below) of colder than -75°C indicate torrential rains.

This is very much a "turn around, don't drown" situation.
