The 2019 ozone hole developed in earnest during the second week of August and initially the ozone hole area rose sharply following a familiar trajectory to past ozone holes, at least until late August. What occurred then was a sudden stratospheric warming event which saw record heat flux transported towards the pole with corresponding record warm temperatures in the Antarctic stratosphere. The impact on the development and overall size of the 2019 Antarctic ozone hole has been dramatic. At the time of writing the abstract (mid-Sep 2019), the daily area of the Antarctic ozone hole was approximately half of what would be expected for this time of year, with all of the other ozone hole metrics also being well below average. The total column ozone images for the first half of September show that the ozone hole was displaced off of the South Pole towards South America, with a band of .

This presentation will give an update on what happened during the rest of the 2019 Antarctic ozone hole season and the 2019 ozone hole metrics will be compared to historical metrics.
