What happened

The episode as NWS VEF wrote it up.

Another in a series of spring storms left significant amounts of precipitation across extreme southern Nevada. The Las Vegas Valley received amounts between one-half (0.50) and three-quarters (0.75) of an inch of rain which filled washes around the metro area with one or two feet of water and flooded some underpasses and low-lying intersections. One person had to be rescued from the Flamingo Wash but only received minor injuries. The Spring Mountains received 10 to 12 inches of snow on previous snowpack but temperatures were too warm for any significant accumulations on paved roads.
