HURRICANE MELISSA HAS ENTERED THE CANADIAN HURRICANE CENTRE RESPONSE

MAXIMUM SUSTAINED WINDS: 139 KILOMETRES PER HOUR.
PRESENT MOVEMENT: NORTHEAST AT 70 KILOMETRES PER HOUR.
MINIMUM CENTRAL PRESSURE: 973 MILLIBARS.
2. PUBLIC WEATHER IMPACTS AND WARNINGS SUMMARY.
THE HURRICANE IS TRANSITIONING 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, PRIMARILY FROM THE LARGE
NON-TROPICAL LOW AND TO A LESSER EXTENT, FROM MELISSA.
A. WIND.
THERE IS A CHANCE THAT PARTS OF THE AVALON COULD BE WITHIN THE STORM
CIRCULATION FOR A BRIEF PERIOD 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
