Monthly Tropical Weather Summary
NWS National Hurricane Center Miami FL
800 AM EDT Tue Oct 1 2019

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

Tropical cyclone activity during September was above average for the
Atlantic basin, with seven named storms forming during the month,
three of them becoming hurricanes, and two reaching major hurricane
status. Based on a 30-year climatology (1981-2010), four named
storms typically form in the basin in September, with three of them
becoming hurricanes, and one of them becoming a major hurricane.

In terms of Accumulated Cyclone Energy (ACE), which measures the
combined strength and duration of tropical storms and hurricanes,
activity in the Atlantic basin in September was well above average,
and the 11th busiest September on record using that metric.

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