2. PUBLIC WEATHER IMPACTS AND WARNINGS SUMMARY.
THE HURRICANE IS EXPECTED TO TRANSITION TO A POST-TROPICAL STORM
PRIOR TO PASSING NEAR OR SOUTH OF THE AVALON PENINSULA OF

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 FRIDAY 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 STAYS SOUTH OF LAND, THE HIGHEST WINDS WOULD NOT
BE MUCH OF A CONCERN. REGARDLESS, GUSTS REACHING 80 KM/H ARE
POSSIBLE FOR PARTS OF THE SOUTHERN AND EASTERN COASTLINE OF THE
AVALON PENINSULA FRIDAY NIGHT. 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. THERE WILL BE SOME ENHANCEMENT OF RAIN
ASSOCIATED WITH THE LOW PRESSURE SYSTEM OVER NEW ENGLAND THAT WILL
GIVE 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 FRIDAY 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 FRIDAY NIGHT
AND CONTINUING INTO SUNDAY MORNING.
3. MARINE WEATHER IMPACTS AND WARNINGS SUMMARY.
