 POST-TROPICAL CYCLONE ARTHUR DISCUSSION NUMBER  19
 NWS NATIONAL HURRICANE CENTER MIAMI FL       AL012014
 1100 AM EDT SAT JUL 05 2014
 
 Surface, satellite, and earlier NOAA reconnaissance aircraft data
 indicate that Arthur became an extratropical cyclone by 1200 UTC
 this morning. The earlier aircraft reports and recent wind
 observations show that the cyclone continues to weaken, and the
 initial intensity is lowered to 50 kt. The post-tropical cyclone
 should continue to weaken during the next day or so and winds are
 expected to be below gale force in 48 to 72 hours.  The cyclone is
 now forecast to dissipate by the end of the forecast period.
 
 The cyclone is moving north-northeastward at about 21 kt.  A
 north-northeastward to northeastward motion at a slower forward
 speed is expected during the next day or so.  A turn toward the
 north and a further reduction in forward speed is forecast in a few
 days.  The lastest track forecast is similar to the previous
 forecast through 48 hours, but has been adjusted westward
 thereafter to be in better agreement with the latest track guidance.
 
 This will be the last NHC advisory on Arthur.  For additional
