Monthly Tropical Weather Summary
NWS National Hurricane Center Miami FL
800 AM EDT Tue Sep 1 2020

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

Tropical cyclone activity in the Atlantic basin during the month of 
August was slightly above average in terms of the number of named 
storms that developed.  Four named storms formed during the month, 
with two of them becoming hurricanes, including Hurricane Laura 
that intensified into a major hurricane.  One tropical depression 
also formed at the end of the month offshore of the southeastern 
U.S. coast. Based on a 30-year climatology (1981-2010), three named 
storms typically form in the basin in August, with one or two of 
them becoming hurricanes, and one of them becoming a major 
hurricane.

In terms of Accumulated Cyclone Energy (ACE), which measures the 
strength and duration of tropical storms and hurricanes, activity 
in the basin so far in 2020 has also been above average, about 40 
percent above the long-term mean.

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