 NWS NATIONAL HURRICANE CENTER MIAMI FL       AL042013
 500 PM AST SAT JUL 27 2013
  
 ASCAT AMBIGUITY DATA FROM A FEW HOURS AGO INDICATED THAT DORIAN NO
 LONGER HAD A CLOSED SURFACE CIRCULATION.  THUS...THE TROPICAL
 CYCLONE HAS SUCCUMBED TO THE HARSH ENVIRONMENT AND HAS DEGENERATED
 INTO A TROPICAL WAVE.  THE MAXIMUM WIND SPEED IS STILL ABOUT 35 KT
 ACCORDING TO THE ASCAT PASS.  REGENERATION OF THIS SYSTEM IS
 UNLIKELY DUE TO PERSISTENT SOUTHWESTERLY SHEAR AND VERY DRY AIR IN
 THE MID-LEVELS OF THE ATMOSPHERE.  THE REMNANTS OF DORIAN SHOULD
 PASS NORTH OF THE LEEWARD ISLANDS AND PUERTO RICO...AND BE IN THE
 VICINITY OF THE SOUTHEASTERN BAHAMAS IN 2-3 DAYS.
 
 AN AIR FORCE RESERVE HURRICANE HUNTER PLANE IS SCHEDULED TO
 INVESTIGATE THE WAVE TOMORROW...IF NECESSARY. 
 
 ADDITIONAL INFORMATION ON THIS SYSTEM CAN BE FOUND IN HIGH SEAS
 FORECASTS ISSUED BY THE NATIONAL WEATHER SERVICE...UNDER AWIPS 
 HEADER NFDHSFAT1 AND WMO HEADER FZNT01 KWBC.
