3. TECHNICAL DISCUSSION  
 
A. ANALYSIS  
 
POST-TROPICAL STORM FIONA IS NOW A LARGE AND POWERFUL MID-LATITUDE  
SYSTEM. LOCAL GUSTS TO NEAR - HURRCANE FORCE PERSIST FOR PARTS OF  
SOUTHWESTERN NEWFOUNDLAND AND ILES-DE-LA-MADELEINE. WIND RADII HAVE  
INCREASED SIGNIFICANTLY OVER THE LAST 12 HOURS. A WIDE BAND OF STORM  
FORCE WINDS ARE EAST OF THE TRACK AND A VERY LARGE AREA OF GALES  
SURROUND THE ENTIRE SYSTEM.  
 
B. PROGNOSTIC  
 
FIONA IS MOVING OFF TO THE NORTHEAST AND WILL SLOWLY ACCELERATE  
TOWARDS SOUTHEAST LABRADOR. WHILE THIS IS HAPPENNING IT WILL BEGIN TO  
INTERACT WITH AN UPPER TROUGH AND CURVE NORTHWARDS. THE SYSTEM WILL  
START TO DEVELOP FRONTAL FEATURES TONIGHT, ALBEIT NOT TOO STRONG.  
MODEL GUIDANCE IS GENERALLY VERY GOOD, AND THE TRACK IS EFFECTIVELY  
UNCHANGED. THE STORM WILL THEN DISSIPATE OVER THE LABRADOR SEA ON  
SUNDAY NIGHT.
