Sergio's 2019 Hurricane Season

The 2019 Atlantic hurricane season is an event in the annual tropical cyclone season in the North Hemisphere. The season officially began on June 1, 2019 and will end on November 30, 2019. These dates, adopted by convention, historically describe the period in each year when most systems form. However, systems can and do form outside these dates, such as Subtropical Storm Andrea, which formed on May 20.

This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season. It includes information that was not released throughout the season, meaning that data from post-storm reviews by the National Hurricane Center, such as a storm that was not initially warned upon, has been included.
