POST-TROPICAL CYCLONE COLIN DISCUSSION NUMBER 10  
NWS NATIONAL HURRICANE CENTER MIAMI FL AL032016  
500 PM EDT TUE JUN 07 2016  
 
COLIN IS NOW BEING ANALYZED AS A FULLY EXTRATROPICAL CYCLONE WITH  
FRONTAL FEATURES. THE GUSTY WINDS AND RAINFALL HAS CLEARED THE  
COAST OF NORTH CAROLINA; THEREFORE THIS WILL BE THE FINAL NHC  
ADVISORY ON THIS SYSTEM. THE LOW'S INTENSITY REMAINS 50 KT, WHICH  
IS IN AGREEMENT WITH AN EARLIER ASCAT PASS THAT SHOWED A LARGE AREA  
OF 40-45 KT WINDS WELL TO THE SOUTHEAST OF THE CENTER. THE  
EXTRATROPICAL CYCLONE WILL LIKELY DEEPEN TONIGHT DUE TO BAROCLINIC  
ENERGETICS, BUT GRADUAL WEAKENING IS FORECAST TO BEGIN ON WEDNESDAY  
WHILE THE LOW MOVES OVER THE NORTH ATLANTIC. THE FORECAST  
INTENSITIES AND WIND RADII ARE BASED ON GUIDANCE PROVIDED BY THE  
OCEAN PREDICTION CENTER.  
 
THE CYCLONE IS RACING NORTHEASTWARD AT ABOUT 35 KT, AND THIS  
GENERAL MOTION IS EXPECTED TO CONTINUE DURING THE NEXT DAY OR SO.  
AFTER THAT TIME, THE LOW SHOULD DECELERATE AS IT MOVES MOVES AROUND  
A COUPLE OF LARGER EXTRATROPICAL LOWS OVER THE NORTH ATLANTIC.  
 
THIS IS THE LAST ADVISORY ISSUED BY THE NATIONAL HURRICANE CENTER  
ON COLIN. FUTURE INFORMATION ON THIS SYSTEM CAN BE FOUND IN HIGH  
SEAS FORECASTS ISSUED BY THE NATIONAL WEATHER SERVICE, UNDER AWIPS  
HEADER NFDHSFAT1, WMO HEADER FZNT01 KWBC, AND AVAILABLE ON THE WEB
