2019 Atlantic Hurricane Season (MK8 Andrew/Tyler14 PythonGBGamer)

The 2019 Atlantic hurricane season was a departure from the above-average activity of the past three seasons. Only 8 storms formed in the basin proper, with 2 hurricanes including 1 major hurricane; however, Hurricane Mario of the Eastern Pacific crossed over into the Gulf of Mexico as a depression and was able to regain tropical storm status before landfall in Louisiana. The season officially began on June 1, 2018, and ended on November 30, 2018. These dates historically describe the period each year when most tropical cyclones form in the Atlantic basin and are adopted by convention.

A record-breaking El Nino combined with an unusually stable atmosphere severely limited cyclogenesis throughout the basin. Only three storms of gale force or stronger (Barry, Dorian, Gabrielle) formed from tropical waves and no depressions formed west of 70 W while south of 20 N. The generally unfavorable conditions also led to the earliest finish to a season since 2006 when Humberto turned extratropical on October 13, and the lowest ACE value since 1983 with 24.9 units generated.
