One tropical storm (Sebastien) formed in the Atlantic basin in the month of November, and one subtropical storm (Rebekah) that formed in October was still active when the month began. On average, one tropical storm forms in the basin every other year in the month of November.

Overall, the 2019 Atlantic hurricane season featured above normal activity. Eighteen named storms formed, of which six became hurricanes and three became major hurricanes - category 3 or higher on the Saffir-Simpson Hurricane Wind Scale. This compares to the long-term average of twelve named storms, six hurricanes, and three major hurricanes. There were also two tropical depressions that did not reach tropical-storm strength. In terms of Accumulated Cyclone Energy (ACE), which measures the combined strength and duration of tropical storms and hurricanes, activity in the Atlantic basin in 2019 was well above the long-term mean.
