Monthly Tropical Weather Summary
NWS National Hurricane Center Miami FL
800 AM PDT Mon Nov 1 2021
For the eastern North Pacific, east of 140 degrees west longitude:
Two tropical cyclones formed in October in the eastern Pacific
basin (Pamela and Rick), and both became hurricanes that made
landfall on the Pacific coast of Mexico. Based on a 30-year
climatology (1991-2020), two 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, the
season to date is 10 to 15 percent below the long-term (1991-2020)
average. The number of named storms (17) in the basin so far in
2021 is slightly above the long-term average (15) through the end of
the month.
Reports on individual cyclones, when completed, are available at
