Timeline of the 2005 Atlantic hurricane season

The timeline of the 2005 Atlantic hurricane season documents the formations, strengthenings, weakenings, landfalls, extratropical transitions, and dissipations of the season's tropical and subtropical storms. The 2005 Atlantic hurricane season was the most active Atlantic hurricane season in recorded history.cite web| author=NOAA | year=2006-04-13| title=NOAA Reviews Record-Setting 2005 Atlantic Hurricane Season| publisher=National Oceanic and Atmospheric Administration | accessdate=2006-04-26| url= http://www.noaanews.noaa.gov/stories2005/s2540.htm] The season saw a record twenty-eight tropical or subtropical storms of which a record four storms achieved Category 5 status. Officially beginning on June 1 2005, and lasting until November 30, the 2005 season persisted into January 2006 due to continued storm activity.

The graphical bar below gives a brief overview of storm activity during the season. Each storm's maximum intensity is represented by the color of its bar. Tropical Storm Zeta persisted into 2006 necessitating the addition of January 2006 in both the graphical and text timelines. The timeline also makes use of information which was not operationally released. Every year, the National Hurricane Center re-analyzes all of the systems of the previous hurricane season and revises their storm histories. New data that was not available while the storm was active is incorporated into these revisions. In this season the revisions were very significant, as an unnamed subtropical storm that went entirely unnoticed was discovered during the post-season review.
