Monthly Tropical Weather Summary

800 AM PST Fri Dec 1 2023

For the eastern North Pacific, east of 140 degrees west longitude:

One tropical storm (Ramon) formed in the eastern Pacific basin in 
the month of November.  Based on a 30-year climatology (1991-2020), 
one named storm typically forms in November every two years.

Overall, the 2023 eastern Pacific hurricane season was near normal 
in terms of the number of named storms but above normal in terms of 
the number of hurricanes and major hurricanes.  In 2023, 17 named 
storms formed, of which 10 became hurricanes and 8 became major 
hurricanes (category 3 or greater on the Saffir-Simpson Hurricane 
Wind Scale).  This compares to the long-term (1991-2020) averages of 
15 named storms, 8 hurricanes, and 4 major hurricanes.  In terms of 
Accumulated Cyclone Energy (ACE), which measures the combined 
strength and duration of tropical storms and hurricanes, activity in 
2023 was about 20 percent above the long-term (1991-2020) average.
