Summary for the 2021 season though :

ABNT30 KNHC 011201

Monthly Tropical Weather Summary
NWS National Hurricane Center Miami FL
800 AM EDT Thu Jul 1 2021

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

One tropical storm (Ana) formed in the Atlantic basin in May, and 
three tropical storms (Bill, Claudette, and Danny) formed in June. 
Claudette and Danny made landfall in the United States as tropical 
storms during the month of June.  So far, this season has been 
considerably more active than average, even compared to the recently 
updated 30-year climatology (1991-2020) where a named storm 
typically forms about once out of every three years in May and about 
once every year in June.

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 2021 is well above average at more than 
twice the climatological value.

Reports on individual cyclones, when completed, are available at
