Monthly Tropical Weather Summary
NWS National Hurricane Center Miami FL
800 AM PST Tue Dec 1 2020

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

Two tropical storms, Odalys and Polo, formed in the basin in 
November.  Although the long-term (1981-2010) average is one 
tropical storm forming in the basin every second or third year, this 
is the third straight November with at least one named storm 
forming.  In fact, named storms have formed in November in six of 
the past seven years in the basin. 

Overall, the 2020 eastern Pacific hurricane season featured an 
average number of named storms, but below average hurricane and 
major hurricane activity. There were sixteen named storms, of which 
four became hurricanes and three became major hurricanes - category 
3 or higher on the Saffir-Simpson Hurricane Wind Scale.  This 
compares to the long-term averages of fifteen named storms, eight 
hurricanes, and four major hurricanes. There were also five tropical 
depressions that did not reach tropical storm strength.

In terms of Accumulated Cyclone Energy (ACE), which measures the 
strength and duration of tropical storms and hurricanes, activity in 
the basin for 2020 was below normal, more than 40 percent below the 
long-term average.
