Monthly Tropical Weather Summary
NWS National Hurricane Center Miami FL
700 AM EST Sun Nov 1 2020
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
Tropical cyclone activity in the Atlantic basin during the month of
October was quite busy with five tropical cyclones developing during
the month. All five systems were named -- Gamma, Delta, Epsilon,
Zeta, and Eta -- although Eta had become a tropical depression on
October 31 and then was named early on November 1 (UTC time).
Three of the storms became hurricanes with two, Delta and Epsilon,
reaching major hurricane strength. Based on a 30-year climatology
(1981-2010), two named storms typically form in the basin in
October, with one of them becoming a hurricane. A major hurricane
forms in the basin in October about once every three years.
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 been well above average, more than
40 percent above the long-term mean.
Reports on individual cyclones, when completed, are available at
the National Hurricane Center website at
