This sometimes follows the opposite format (e.g., "There are warnings of gales in all areas except Biscay, Trafalgar and FitzRoy"). The "General Synopsis" follows, giving the position, pressure (in millibars) and track of pressure areas (e.g., "Low, Rockall, 987, deepening rapidly, expected Fair Isle 964 by 0700 tomorrow").

Southerly Buster light drizzle. It is proposed that the southerly buster is basically a coastal gravity current that is held against the mountains by the Coriolis force and in transverse geostrophic balance, and is generated when a cold front is obstructed, experiencing anticyclonic distortion near the Great Dividing Range, spreading northward as a coastal trapped orographic jet. The southerly buster is caused by its interaction with the Great Dividing Range, as the cool air becomes trapped against the ranges, oftentimes in the Gippsland area of Victoria, where the mountains create a channelling effect as the southerly winds move across the New South
