SYSTEM OVER QUEBEC. THE CHC WILL CONTINUE TO MESSAGE AND MONITOR THE
SITUATION UNTIL SATURDAY EVENING. ALL OFFICIAL WEATHER ALERTS ARE
BEING HANDLED BY THE LOCAL FORECAST OFFICES.
A. WIND.
IMPACTS:
WE DON'T EXPECT WINDS TO BE AS STRONG AS HURRICANE LEE SO IMPACTS
MAY BE LIMITED MOSTLY TO THE BREAKING OF SOME TREE BRANCHES WITH THE
OCCASIONAL POWER/UTILITY INTERRUPTION.
DETAILS:
STRONG SOUTHEASTERLY WINDS GUSTING 70 KILOMETRES PER HOUR ARE
EXPECTED WITH GUSTS TO 90 KILOMETRES PER HOUR OVER EXPOSED AREAS.
THE STRONGEST WINDS ARE EXPECTED TO REACH SOUTHWESTERNMOST AREAS OF
THE SOUTH SHORE OF NOVA SCOTIA INCLUDING YARMOUTH AND SHELBURNE THIS
EVENING. THESE WINDS WILL REACH THE HALIFAX AREA AND THE ANNAPOLIS
VALLEY OVERNIGHT. WINDS WILL SHIFT TO SOUTHWESTERLY AND DIMINISH
SUNDAY MORNING.
B. RAINFALL.
LIGHT TO MODERATE RAIN WILL BEGIN LATE THIS AFTERNOON OR EARLY THIS
EVENING OVER DIGBY, YARMOUTH AND SHELBURNE COUNTIES. THE RAIN WILL
BECOME HEAVIER AT TIMES AND SPREAD EASTWARD REACHING HALIFAX AND THE
MOST OF THE ANNAPOLIS VALLEY BY MIDNIGHT. RAIN WILL REACH HANTS
COUNTY OVERNIGHT.
RAINFALL AMOUNTS ARE FORECAST TO BE IN THE 40 TO 60 MILLIMETRES
RANGE IN DIGBY, YARMOUTH, SHELBURNE, QUEENS AND LUNENBURG COUNTIES
WHERE THERE IS A RAINFALL WARNING IN EFFECT. RAINFALL AMOUNTS OF 30
TO 40 MILLIMETRES ARE FORECAST FOR ANNAPOLIS AND KINGS COUNTIES AND
HALIFAX METRO AND HALIFAX COUNTY WEST. 20 TO 30 MILLIMETRES ARE
FORECAST FOR HANTS COUNTY.
C. SURGE/WAVES.
IMPACTS:
AS WITH THE WINDS, WE DON'T EXPECT WAVES AND STORM SURGE TO BE AS
BAD AS LEE, BUT THE SAME STRETCH OF COAST IMPACTED BY LEE WILL BE
AFFECTED BY EX-PHILIPPE. THERE COULD BE SOME WAVE OVERWASH AND MINOR
TO MODERATE COASTAL FLOODING DEPENDING ON THE TIMING OF CONDITIONS
WITH HIGH TIDE DURING THE VERY EARLY MORNING HOURS SUNDAY.
DETAILS:
SIGNIFICANT WAVE HEIGHTS OVER MARINE AREAS SOUTH OF NOVA SCOTIA ARE
EXPECTED TO BE IN EXCESS OF 5 METRES - POSSIBLY UP TO 8 METRES. THE
LARGEST WAVES ARE EXPECTED SATURDAY NIGHT, SUBSIDING DURING THE DAY
SUNDAY.
MODERATE TO HEAVY SURF AND STORM SURGE WITH ELEVATED WATER LEVELS
ARE EXPECTED ALONG THE SOUTH SHORE OF NOVA SCOTIA EASTWARD ALONG THE
COAST TO THE HALIFAX REGION. THESE CONDITIONS COULD BE IMPACTFUL
OVERNIGHT SATURDAY NIGHT IF TIMED WITH THE HIGH TIDES. HIGH TIDE
NEAR HALIFAX IS AT 4:13 A.M. SUNDAY. HIGH TIDE NEAR SHELBURNE IS AT
4:50 A.M.
WAVES AND WATER LEVELS ARE NOT EXPECTED TO BE PROBLEMATIC IN AND
AROUND THE BAY OF FUNDY DUE TO REDUCED AMPLITUDE OF THE TIDAL CYCLE
THIS WEEKEND.
3. MARINE WEATHER IMPACTS AND WARNINGS SUMMARY.
STORM WARNINGS ARE IN EFFECT FOR LURCHER, BROWNS BANK, GEORGES BANK,
SOUTHWESTERN SHORE, LAHAVE BANK, WEST SCOTIAN SLOPE AND EAST SCOTIAN
