Monthly Tropical Weather Summary
NWS National Hurricane Center Miami FL
800 AM EDT Mon Nov 1 2021
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
One subtropical cyclone, Subtropical Storm Wanda, formed in the
Atlantic basin during October, and was ongoing at the end of the
month over the north-central portion of the Atlantic basin. In
addition, both Hurricane Sam and Tropical Storm Victor continued
from the end of September through the first few days of October.
Based on a 30-year climatology (1991-2020), two to three named
storms typically form in October, with one of them becoming a
hurricane. A major hurricane tends to form in October every one to
two 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 2021 has been above normal, about 20 percent
above the long-term (1991-2020) mean to date. The 21 named storms
through the end of October is above the 30-year (1991-2020) average
of 13 to 14 named storms by the end of October.
