Another shot of a late season storm cell passing south of
Tucson, kicking up a dust storm ("haboob") in the process.
The haboob is that layer of yellowish orange gunk just
above the skyline. It looks deceptive here, but it is
probably 1000 feet high nearest the lightning bolts.
This is a single exposure of a single flash of lightning.
I don't really understand why there are multiple bolts.
