Meteosat infra‐red imagery for the Great Storm of October 1987 is analysed to show a series of very shallow arc‐shaped and smaller chevron‐shaped cloud features that were associated with damaging surface winds in the dry‐slot region of this extra‐tropical cyclone. Hypotheses are presented that attribute these low‐level cloud features to boundary‐layer convergence lines ahead of wind maxima associated with the downward transport of high momentum from overrunning, so‐called sting‐jet, flows originating in the storm's main cloud head.
