On October 12 and 13 an explosive cyclone or weather bomb, as they are popularly known, hit Adelie Land, where the French research station in the Antarctic, Dumont D’Urville, is located .

The cyclone reached category 2 on the Bergeron scale (on this scale the strongest are rated category 3), showed a drop in atmospheric pressure of 30.4 hPa in 24 hours and reached a minimum value of 963.3 hPa at the station, but at the center of the cyclone the value was even lower, 946 hPa. The cyclone produced sustained winds of 119 km/h (74 mph) and maximum gusts that reached 178 km/h (111 mph). Although these winds are intense, they are still far from the record recorded at this station, which was 211 km/h (131 mph) on May 1957, one of the strongest winds ever recorded on the continent.

This was the most intense of the eight explosive cyclones that hit this station in 2017, and this occasion was recorded by the animations of the high resolution images provided by the site http://wx.inside.net/ which provides daily images of various very high parts of the globe. From 00:25 min it is possible to identify the cyclone in its occlusal phase reaching the coast of the Antarctic continent.
