==DISCUSSION==
ON FRIDAY HURRICANE KATIA ENTERED CANADIAN WATERS SOUTH OF NOVA
SCOTIA.  KATIA LOST ITS TROPICAL CHARACTERISTICS SATURDAY MORNING AS 
IT PASSED SOUTH OF NEWFOUNDLAND.  POST-TROPICAL STORM KATIA REACHED 
THE SOUTHEASTERN GRAND BANKS SATURDAY AFTERNOON AND THEN ACCELERATED 
EASTWARD TOWARDS NORTHERN EUROPE.  THE LOWEST ESTIMATED PRESSURE
OVER CANADIAN WATERS WAS 955 MB WHICH OCCURRED DURING THE LATTER 
STAGE OF TRANSITION INTO A POST-TROPICAL STORM.  ALTHOUGH THE CLOUD 
SHIELD ASSOCIATED WITH KATIA SHROUDED MUCH OF THE ATLANTIC PROVINCES 
THE PRECIPITATION STAYED WELL OFFSHORE.  RAINFALL AT SABLE ISLAND
WAS ONLY 20 MM. HOWEVER, ESTIMATED RAINFALL TOTALS ALONG THE TRACK
OF KATIA WERE IN THE ORDER OF 60 TO 120 MM.  OFFSHORE WATERS SOUTH
OF THE ATLANTIC PROVINCES WERE HARDEST HIT WITH HURRICANE FORCE
WINDS AND PEAK WAVES ABOVE 10 METRES RECORDED BY THE MSC BUOY
