The 2017 Atlantic hurricane season was an event in the annual tropical cyclone season in the north Atlantic Ocean. This Atlantic hurricane season saw above-normal activity;[nb 1] it was the seventh most active season on record and the most active since 2005.[2] The season officially began on June 1, 2017 and ended on November 30, 2017. These dates, adopted by convention, historically describe the period in each year when most tropical systems form.[3] However, storm formation is possible at any time of the year, as demonstrated in 2017 by the formation of the season's first named storm, Tropical Storm Arlene, on April 19. The final storm of the season, Tropical Storm Rina degenerated to a remnant area of low pressure on November 9.

The 2017 season produced 17 named storms, of which 10 became hurricanes including six of which intensified into major hurricanes (Category 3, 4 or 5). Of those six, Harvey and Irma, became the first major hurricanes to make landfall on the continental United States in 12 years;[2] a third hurricane, Nate, did so as well. September was both the most active month in the season and the most active month for Atlantic hurricanes ever recorded. Four long-lived major hurricanes—Irma, Jose, Lee and Maria—moved through the Atlantic Basin, as did the short-lived Hurricane Katia. Overall, more accumulated cyclone energy was generated during September 2017 than during the entire 2016 season.[4] In April 2018, the World Meteorological Organization retired the names Harvey, Irma, Maria, and Nate from its rotating naming lists due to the number of deaths and amount of damage they caused, and they will not be used again for another Atlantic hurricane.[5]

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.

By convention, meteorologists use one time zone when issuing forecasts and making observations: Coordinated Universal Time (UTC), and also use the 24-hour clock (where 00:00 = midnight UTC).[6] The National Hurricane Center uses both UTC and the time zone where the center of the tropical cyclone is currently located. The time zones utilized (east to west) prior to 2020 were: Atlantic, Eastern, and Central.[7] In this timeline, all information is listed by UTC first with the respective regional time included in parentheses. Additionally, figures for maximum sustained winds and position estimates are rounded to the nearest 5 units (knots, miles, or kilometers), following the convention used in the National Hurricane Center's products. Direct wind observations are rounded to the nearest whole number. Atmospheric pressures are listed to the nearest millibar and nearest hundredth of an inch of mercury.
