Timeline of the 2002 Atlantic hurricane season

The 2002 Atlantic hurricane season was an average Atlantic hurricane season in which twelve named storms formed. Although Tropical Storm Arthur formed on July 14, the season officially began on June 1 and ended on November 30, dates that conventionally delimit the period of each year when most tropical cyclones develop in the Atlantic basin. The season's final storm, Tropical Depression Fourteen, dissipated on October 16.

The season produced fourteen tropical depressions, of which twelve intensified into tropical storms, four became hurricanes, and two became major hurricanes. The two most significant storms of the season, in terms of loss of life and damage, were hurricanes Isidore and Lili. Hurricane Isidore was an unusually large storm and attained maximum sustained winds of 125 mph (205 km/h), becoming one of only two major hurricanes during the season. Hurricane Lili was the strongest hurricane during the season, with winds reaching 145 mph (230 km/h) before moving ashore Louisiana as a much weaker system.

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.

The time stamp for each event is first stated using Coordinated Universal Time (UTC), the 24-hour clock where 00:00 = midnight UTC. The NHC 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. In this timeline, the respective area time is included in parentheses. Additionally, figures for maximum sustained winds and position estimates are rounded to the nearest 5 units (miles, or kilometers), following National Hurricane Center practice. 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.
