 IRENE HAS ACCELERATED FURTHER AND IS NOW MOVING NORTHEASTWARD NEAR
 40 KT.  ALTHOUGH IT IS DIFFICULT TO ESTIMATE THE INTENSITY FROM
 SATELLITE PICTURES...SUCH A FAST FORWARD MOTION WOULD SUPPORT 50 KT
 WINDS.  VISIBLE SATELLITE IMAGERY AND SURFACE OBSERVATIONS INDICATE
 THAT THE STORM IS INTERACTING WITH A FRONTAL ZONE AND ASSOCIATED
 EXTRATROPICAL LOW JUST EAST OF NEWFOUNDLAND...INDICATING THAT IRENE
 IS TRANSITIONING INTO AN EXTRATROPICAL STORM.  LATEST GLOBAL MODEL
 GUIDANCE INDICATES THAT THE EXTRATROPICAL VERSION OF IRENE WILL
 SOON BE ABSORBED BY THE LARGER BAROCLINIC CYCLONE...AND SPREAD A
 LARGE AREA OF GALE FORCE WINDS OVER A PORTION OF THE NORTH
 ATLANTIC.
 
 THIS IS THE LAST ADVISORY ISSUED BY THE NATIONAL HURRICANE CENTER ON
 IRENE.  FUTURE INFORMATION...IF ANY...ON THIS SYSTEM MAY BE FOUND
 IN HIGH SEAS FORECASTS ISSUED BY THE OCEAN PREDICTION
