A cut-off low is a meteorological term that refers to a low-pressure system that has detached or "cut off" from the prevailing mid-latitude westerlies, typically becoming isolated from the main jet stream. This phenomenon often occurs when a low-pressure area, which has developed typically in the mid or upper levels of the atmosphere, becomes surrounded by high pressure on all sides.
