Monthly Tropical Weather Summary
NWS National Hurricane Center Miami FL
800 AM EDT Mon Oct 1 2018

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

September was above average in the Atlantic basin in terms of the
number of named storms that formed during the month (7).  The
numbers of hurricanes (3) and major hurricanes (1) were near the
long-term averages for the month.  One short-lived tropical
depression also formed in September.  Based on a 30-year climatology
(1981-2010), four named storms typically form in the Atlantic basin
in September, with two or three becoming hurricanes and one or two
reaching major hurricane status.

In terms of Accumulated Cyclone Energy (ACE), which measures the
combined strength and duration of tropical storms and hurricanes,
activity in the Atlantic basin thus far in 2018 has been near
normal.

Reports on individual cyclones, when completed, are available at
the National Hurricane Center website at
