Monthly Atlantic Tropical Weather Summary

ABNT30 KNHC 011150

800 AM EDT SAT OCT 01 2016

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

Five named storms formed in the Atlantic basin in September.  One of
these, Matthew, reached major hurricane strength over the south-
central Caribbean Sea.  In addition, Hermine, which formed at the
end of August, reached hurricane strength on September 1.  Based on
a 30-year (1981-2010) climatology, 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 basin so far in 2016 is slightly below normal.  The
ACE through the end of September is about 90 percent of the 1981-
2010 median value to date.

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