==DISCUSSION==
THE NEXT INFORMATION STATEMENT WILL BE ISSUED BY 9:30 A.M. NDT.
HURRICANE MELISSA IS CONTINUING TO THE NORTHEAST AND ACCELERATING
TOWARDS THE ATLANTIC CANADIAN MARINE REGION TODAY. MELISSA IS
EXPECTED TO REACH MARITIME OFFSHORE WATERS THIS AFTERNOON, THEN
CONTINUE NORTHEASTWARD INTO NEWFOUNDLAND WATERS PASSING CLOSE TO THE
SOUTHEASTERN AVALON PENINSULA LATE TONIGHT INTO EARLY SATURDAY. A
PERIOD OF HEAVY RAIN, STRONG WINDS ALONG WITH HEAVY SURF IS
EXPECTED.
1. SUMMARY OF BASIC INFORMATION AT 3:30 A.M. NDT.
LOCATION: 34.7 NORTH 65.5 WEST.
ABOUT 270 KILOMETRES NORTH-NORTHWEST OF BERMUDA.
MAXIMUM SUSTAINED WINDS: 157 KILOMETRES PER HOUR.
PRESENT MOVEMENT: NORTHEAST AT 69 KILOMETRES PER HOUR.
MINIMUM CENTRAL PRESSURE: 971 MILLIBARS.
2. PUBLIC WEATHER IMPACTS AND WARNINGS SUMMARY.
THE HURRICANE IS BEGINNING TO TRANSITION TO A POST-TROPICAL STORM,
AND THIS TRANSITION IS EXPECTED TO BE COMPLETED PRIOR TO PASSING
NEAR OR SOUTH OF THE AVALON PENINSULA OF NEWFOUNDLAND EARLY ON
SATURDAY. IF IT ENDS UP TRACKING FURTHER WEST, HEAVY RAIN AND
STRONGER WINDS MAY BE FELT FOR PARTS OF THE AVALON. THERE WILL BE
LARGE WAVES AND HEAVY SURF FOR THE SOUTHERN COAST OF NEWFOUNDLAND
BEGINNING LATE THIS EVENING AND CONTINUING ON SATURDAY.
A. WIND.
THERE IS A CHANCE THAT PARTS OF THE AVALON COULD BE WITHIN THE STORM
CIRCULATION AND THEREFORE WOULD SEE SOME MODERATE WINDS. IF THE
CENTRE OF THE STORM PASSES SOUTH AND EAST OF LAND, THE HIGHEST WINDS
WOULD REMAIN OFFSHORE. REGARDLESS, GUSTS REACHING 80 KM/H ARE
POSSIBLE FOR PARTS OF THE SOUTHERN AND EASTERN COASTLINE OF THE
AVALON PENINSULA OVERNIGHT TONIGHT. STRONG SOUTHWEST WINDS WILL ALSO
PERSIST ACROSS THE REGION ON SATURDAY.
B. RAINFALL.
WITH MELISSA EXPECTED TO TRACK NEAR OR JUST OFFSHORE OF THE AVALON
PENINSULA OF NEWFOUNDLAND, A SHORT PERIOD OF HEAVY RAIN IS POSSIBLE
OVER A 3 TO 6 HOUR WINDOW TONIGHT. THERE WILL BE SOME ENHANCEMENT OF
RAIN ASSOCIATED WITH THE LOW PRESSURE SYSTEM OVER NEW ENGLAND THAT
WILL GIVE A PERIOD OF HEAVY RAIN FROM SOUTHEASTERN ONTARIO TOWARDS
NEWFOUNDLAND AND LABRADOR.
C. SURGE/WAVES.
FOR SOUTHEASTERN NEWFOUNDLAND, LARGE WAVES WILL ARRIVE AND BUILD
FROM THE SOUTHWEST LATE THIS EVENING, PEAKING EARLY SATURDAY WITH
BREAKING SIGNIFICANT WAVE HEIGHTS OF 5 TO 7 METRES FORECAST. THESE
WAVES COMBINED WITH THE POSSIBILITY OF STORM SURGE MAY CAUSE HIGHER
THAN NORMAL WATER LEVELS PARTICULARLY ALONG SOUTHWEST-FACING
SHORELINES IN THE BURIN AND AVALON PENINSULAS BEGINNING LATE
OVERNIGHT TONIGHT AND CONTINUING INTO SUNDAY MORNING.
3. MARINE WEATHER IMPACTS AND WARNINGS SUMMARY.
HURRICANE FORCE WIND WARNINGS ARE NOW IN EFFECT FOR THE SOUTHEASTERN
HALF OF LAURENTIAN FAN AND THE GRAND BANKS. STORM FORCE WIND
WARNINGS ARE IN EFFECT FOR EASTERN BANQUEREAU, NORTHWESTERN
