MONTHLY TROPICAL WEATHER SUMMARY  
NWS NATIONAL HURRICANE CENTER MIAMI FL  
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.
