A diagnostic study of the Flateyri avalanche cyclone, 24-26 October 1995, using potential vorticity inversion

While this part of the country is frequently hit by avalanches, usually in connection with violent winds from the north (N) or northeast (NE), the timing of this avalanche makes it very exceptional, since in late October there is usually little preexisting snow in the hills. The conditions leading to the avalanches can be explained by noting that in addition to frontal precipitation associated with the deep cyclone there was low-level advection of very cold air from a persistent cold high over Greenland.
