POST-TROPICAL CYCLONE RINA DISCUSSION NUMBER 14  
NWS NATIONAL HURRICANE CENTER MIAMI FL AL192017  
1100 AM AST THU NOV 09 2017  
 
SATELLITE IMAGES AND SURFACE DATA INDICATE THAT RINA HAS BECOME A  
POST-TROPICAL CYCLONE. THE SYSTEM IS EMBEDDED WITHIN LOW STRATUS  
CLOUDS, WITH NIPPY AIR TEMPERATURES AROUND 45 DEG F ABOUT A DEGREE  
TO THE NORTHWEST OF THE CENTER. INTERESTINGLY, DESPITE BEING OVER  
WATER TEMPERATURES AROUND 9 DEG C, INSTABILITY ALOFT IS STILL  
PRODUCING SOME ELEVATED DEEP CONVECTION WELL NORTHEAST OF THE  
CENTER, THOUGH THIS IS NOT INDICATIVE OF TROPICAL CYCLONE STATUS.  
THE INITIAL WIND SPEED WILL STAY AT 40 KT, WHICH IS THE MAXIMUM WIND  
VALUE FROM A PAIR OF RECENTLY RECEIVED SCATTEROMETER PASSES. THE  
CYCLONE SHOULD MOVE RATHER RAPIDLY TO THE NORTHEAST AND  
EAST-NORTHEAST OVER THE NEXT DAY BEFORE BECOMING ELONGATED AND  
DISSIPATING WEST OF IRELAND. LITTLE CHANGE IN STRENGTH IS  
ANTICIPATED, CONSISTENT WITH THE GLOBAL MODELS.  
 
THIS IS THE LAST ADVISORY ON RINA. ADDITIONAL 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 AT  
HTTP://OCEAN.WEATHER.GOV/SHTML/NFDHSFAT1.SHTML  
 
HOPEFULLY RINA WILL BE THE FINALE OF THE EXTREMELY ACTIVE 2017  
ATLANTIC HURRICANE SEASON. HOWEVER THAT MIGHT BE WISHFUL THINKING  
SINCE, OF THE TOP 10 MOST ACTIVE HURRICANE SEASONS BEFORE THIS YEAR,  
SEVEN OF THEM STILL HAD ANOTHER TROPICAL STORM AFTER TODAY'S DATE.
