[1][3] September 21 was the final date on which a system of at least tropical storm strength was active; this was described in a 1995 retrospective from Monthly Weather Review as the earliest such occurrence since 1930.

After hitting Nicaragua, Gert—a sprawling and moisture-laden tropical cyclone—generated heavy rainfall over a large portion of Central America and Mexico.

[11] At the end of the month, the western eyewall of Hurricane Emily passed over the Outer Banks of North Carolina while the storm was near its peak intensity; powerful winds and record-breaking floods caused three fatalities and heavy but localized damage.

Additionally, figures for maximum sustained winds and position estimates are rounded to the nearest five units (knots, miles, or kilometers) and averaged over one minute, following National Hurricane Center practice.

This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season.
