- Weak rotation in a collapsing wall cloud as a storm is weakening
- W012830Z
- A collapsing wall cloud in a brooding stormy sky. Weak rotation is concentrated in the thicker part beside the rain at right. A cloud extension toward the left has formed where undercutting outflow lifts warm air on a trajectory into the main updraft of the storm. The storm is weakening and will soon die.
