Monthly Tropical Weather Summary

800 AM PST Wed Dec 1 2021

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

Two tropical cyclones formed in November in the eastern Pacific 
basin (Sandra and Terry).  Based on a 30-year climatology 
(1991-2020), one named storm typically forms in November every 
second or third year.  However, this is the fourth straight 
November with at least one named storm forming.  In addition, both 
Sandra and Terry were tropical storms simultaneously, which is the 
first time this has occurred in the eastern Pacific in November. 

Overall, the 2021 eastern Pacific hurricane season featured an above 
average number of named storms, an average amount of hurricanes, but 
a below average number of major hurricanes. There were nineteen 
named storms, eight hurricanes, and two major hurricanes. This 
compares to the long-term averages of fifteen named storms, eight 
hurricanes, and four major hurricanes. In terms of Accumulated 
Cyclone Energy (ACE), which measures the strength and duration of 
tropical storms and hurricanes, the activity in the Eastern Pacific 
was about 30 percent below the long-term (1991-2020) average.
