The Atlantic hurricane season has been very active with multiple landfalling hurricanes. With tropical storm Vicky forming a couple of days ago it just leaves Wilfred left this season.
21 out of the 26 letters of the Alphabet are used – We are currently at 20.
Once this list becomes exhausted the Greek alphabet is used.
This has only happened once before in the 2005 hurricane season.
6 letters of the Greek alphabet were used in 2005.
This is the 2020 stats so far from Wikipedia
I expect the 2020 season to see quite a few more named storms and get a fair way into the Greek alphabet. Conditions are extremely favourable.
