A cutoff low forming, as seen on water vapour satellite loops
Overview
This page shows the satellite imagery over the eastern Pacific Ocean during a time when a cutoff low formed.
A trough was digging right next to a strong southwesterly feed. The ensuing shear caused a cutoff low to form; its formation is very interesting to view.
