3. TECHNICAL DISCUSSION  
 
A. ANALYSIS  
 
MARIA IS TRACKING EAST-NORTHEASTWARD WELL SOUTH OF ATLANTIC CANADA.  
THE STORM HAS ACCELERATED AND IS NOW MOVING EAST-NORTHEASTWARD AT 27  
KNOTS. SWELL WAVES OF 2 TO 3 METRES ARE BEING REPORTED BY OFFSHORE  
BUOYS SOUTH OF NOVA SCOTIA.  
 
B. PROGNOSTIC  
 
MARIA WILL CONTINUE TO RIDE ALONG THE GULF STREAM FOR THE NEXT COUPLE  
DAYS. IT IS NOT LIKELY TO BECOME EMBEDDED IN THE BAROCLINIC FLOW TO  
ITS NORTH UNTIL LATER THIS WEEKEND AND WILL LIKELY HOLD AN INTENSITY  
OF 50 TO 55 KTS THROUGHOUT THE FORECAST PERIOD.  
 
THE TRACK FORECAST BASED ON INITIAL MOTION IS ONCE AGAIN ADJUSTED  
SOUTHWARD. THEREFORE GALES ASSOCIATED WITH MARIA ARE NO LONGER  
EXPECTED TO AFFECT THE SOUTHERN GRAND BANKS.  
 
WEAKENING TROPICAL STORM LEE WILL ALSO PASS SOUTH OF THE DISTRICT. ITS  
CIRCULATION IS MUCH SMALLER SO NO IMPACT IS EXPECTED ON THE GRAND  
BANKS.
