3. TECHNICAL DISCUSSION  
 
A. ANALYSIS  
 
FIONA INTENSIFIED TO 115 KNOTS THIS MORNING, WHICH IS CATEGORY 4  
HURRICANE STRENGTH. HOWEVER, IN RECENT IR AND VISIBLE IMAGERY, THE EYE  
IS BECOMING LESS DISTINCT DESPITE THE CLOUD TOPS REMAINING VERY COLD  
WITH A WELL DEFINDED CDO. THE INITIAL INTENSITY IS LOWERED A LITTLE TO  
110 KNOTS. THERE IS SOME WEST TO SOUTHWESTERLY SHEAR IMPACTING THE  
SYSTEM. IN FACT IT WOULD APPEAR AS THOUGH EXTRA-TROPICAL TRANSITION IS  
SOON GOING TO OCCUR. FIONA IS RACING NORTH-NORTHEASTWARD AT ABOUT 33  
KNOTS AS IT IS BEING STEERED BY THE TROUGH TO ITS NORTHWEST. THE  
INITIAL POSITION HAD TO BE ADJUSTED A LITTLE TO REFLECT THE INCREASE  
IN FORWARD SPEED.  
 
B. PROGNOSTIC  
 
FIONA WILL CONTINUE TO ACCELERATE TO THE NORTH-NORTHEAST THIS EVENING  
UNDER THE INFLUENCE OF THE TROUGH OF LOW PRESSURE TO ITS NORTHWEST.  
THE HURRICANE WILL TAKE A SLIGHT HOOK TO THE NORTHWEST AS IT BECOMES  
UNDER THE INFLUENCE OF THE AFOREMENTIONED TROUGH WHILE IT UNDERGOES  
EXTRA-TROPICAL TRANSITION. THEN POST-TROPICAL STORM FIONA IS EXPECTED  
TO MAKE LANDFALL OVER EASTERN MAINLAND NOVA SCOTIA NEAR THE TOWN OF  
CANSO EARLY SATURDAY MORNING WHILE DECELERATING SLIGHTLY AND  
MAINTAINING SUSTAINED HURRICANE FORCE WINDS. AFTER MOVING NEAR THE  
NORTHERN TIP OF CAPE BRETON, THE STORM WILL CONTINUE TO WEAKEN AS IT  
TRACKS NEAR THE WEST COAST OF NEWFOUNDLAND SATURDAY NIGHT THEN  
EVENTUALLY OVER THE LABRADOR SEA LATER SUNDAY.
