Atlanta, September 5, 2017.

At least twenty-six explosive cyclones or weather bombs, as they are popularly known, hit the coast of the Antarctic continent this August.
Two of these twenty-six cyclones reached category 3 of the Bergeron scale (which ranges from 1 to 3). The most intense was recorded on August 6 when a category 3 cyclone hit the Australian Casey station with maximum winds that reached 200 km/h (126 mph); there are no records of damage to the research station.

The American stations of Palmer and McMurdo were each hit by two explosive cyclones, but these were less intense reaching the maximum category 2 of Bergeron scale.

The weather bomb season in Antarctica typically runs from approximately the second fortnight of July to the first week of October, so many other intense cyclones may occur on the continent in the next few weeks.

We will soon be issuing a complete newsletter containing detailed information on all the cyclones that hit the Antarctic this August.
