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.
