Monthly Tropical Weather Summary

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
Tropical cyclone activity this November was above average in terms
of the number of named storms, hurricanes, and major hurricanes in
the Atlantic basin. Three named storms formed during the month,
including one (Rafael) that became a major hurricane. Based on a
30-year climatology (1991-2020), a tropical storm forms in November
once every year or two, and a hurricane forms once every two years.
Rafael strengthened into a hurricane while passing near Jamaica and
the Cayman Islands before making landfall in western Cuba as a
category 3 hurricane. Elsewhere, Patty brought tropical storm
conditions to portions of the Azores. Sara meandered near the coast
of Honduras before making landfall as a tropical storm in Belize.
Overall, the 2024 Atlantic hurricane season had above-normal
activity in terms of the number of named storms, hurricanes, and
major hurricanes. In 2024, there were 18 named storms that formed in
the Atlantic basin, of which 11 became hurricanes and 5 strengthened
into major hurricanes (category 3 or higher on the Saffir-Simpson
Hurricane Wind Scale). These numbers are greater than the long-term
(1991-2020) averages of 14 named storms, 7 hurricanes, and 3 major
hurricanes. In terms of Accumulated Cyclone Energy (ACE), which
measures the strength and duration of tropical storms and
hurricanes, activity in the basin in 2024 was about 34 percent above
the long-term (1991-2020) average.
