This timeline documents all the storm formations, strengthening, weakening, landfalls, extratropical transitions, as well as dissipation.For convenience and clarity, in the timeline below, all landfalls are bolded. The timeline will also include information, when it becomes available, which was not operationally released, meaning that information from post-storm reviews by the National Hurricane Center, such as information on a storm that was not operationally warned on, have been included.

The graphical bar below gives a brief overview of storm activity during the season, and for convenience, the storm's maximum intensity is included as a color bar.
