FOR THE NORTH ATLANTIC...CARIBBEAN SEA AND THE GULF OF MEXICO:  
 
NO TROPICAL CYCLONES OCCURRED IN THE BASIN DURING NOVEMBER, WHICH IS  
NOT UNCOMMON SINCE A NOVEMBER TROPICAL STORM OCCURS ABOUT ONCE EVERY  
OTHER YEAR.  
 
OVERALL, THE 2018 ATLANTIC HURRICANE SEASON FEATURED ABOVE NORMAL  
ACTIVITY. FIFTEEN NAMED STORMS FORMED, OF WHICH EIGHT BECAME  
HURRICANES AND TWO BECAME MAJOR HURRICANES - CATEGORY 3 OR HIGHER ON  
THE SAFFIR-SIMPSON HURRICANE WIND SCALE. THIS COMPARES TO THE  
LONG-TERM AVERAGE OF 12 NAMED STORMS, 6 HURRICANES, AND 3 MAJOR  
HURRICANES. THERE WAS ALSO ONE TROPICAL DEPRESSION THAT DID NOT  
REACH TROPICAL-STORM STRENGTH. IN TERMS OF ACCUMULATED CYCLONE  
ENERGY (ACE), WHICH MEASURES THE COMBINED STRENGTH AND DURATION OF  
TROPICAL STORMS AND HURRICANES, ACTIVITY IN THE ATLANTIC BASIN IN  
2018 WAS ALSO ABOVE NORMAL. IN ADDITION, 7 SYSTEMS WERE  
SUBTROPICAL AT SOME POINT IN THEIR LIFETIME THIS SEASON, WHICH  
ECLIPSES THE PREVIOUS RECORD OF 5 IN 1969.
