2. PUBLIC WEATHER IMPACTS AND WARNINGS SUMMARY.
REMINDER: THIS BULLETIN IS IN EFFECT ONLY FOR WESTERN AND CENTRAL
PARTS OF NOVA SCOTIA INCLUDING HALIFAX AND ADJACENT WATERS. RAINFALL
AND WIND WARNINGS ARE BEING MANAGED BY THE ATLANTIC STORM PREDICTION
CENTRE.
THE REMNANTS OF PHILIPPE AND ANOTHER LOW PRESSURE SYSTEM OF
SUBTROPICAL ORIGINS ARE NOW A COMBINED WEATHER SYSTEM THAT WILL
IMPACT PARTS OF THE MARITIMES WITH STRONG WINDS AND HEAVY RAIN
TONIGHT/EARLY SUNDAY.
RAINFALL WARNINGS ARE NOW IN EFFECT OVER WESTERNMOST NOVA SCOTIA AND
WIND WARNINGS HAVE BEEN POSTED FOR BASICALLY ALL OF ATLANTIC COASTAL
NOVA SCOTIA INCLUDING THE HALIFAX REGION.
THE CANADIAN HURRICANE CENTRE WILL CONTINUE TO MESSAGE ON THE
COMBINED SYSTEM (PHILIPPE AND THE SUBTROPICAL LOW) UNTIL THIS
EVENING. THE LAST OFFICIAL TRACK AND TECHNICAL BULLETIN WILL BE AT
3:00 P.M. TODAY AND A FINAL VERSION OF THIS BULLETIN EARLY THIS
EVENING WITH SOME FINAL INFORMATION.
BY TOMORROW MORNING EVERYTHING WILL BE MERGED WITH A MUCH LARGER
THIRD LOW PRESSURE SYSTEM OVER QUEBEC.
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 OCCUR OVER WESTERN NOVA SCOTIA BY LATER
THIS EVENING AND BECOME HEAVIER AT TIMES AND SPREAD EASTWARD
REACHING HALIFAX AND MOST OF THE ANNAPOLIS VALLEY BY MIDNIGHT AND
HANTS COUNTY AFTER MIDNIGHT.
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
COASTAL FLOODING AROUND HIGH TIDE APPROXIMATELY 4:30 AM. IT LOOKS
LIKE THE PEAK CONDITIONS WILL OCCUR CLOSER TO LOW TIDE NOW, WHICH IS
MID-MORNING TOMORROW.
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.
WAVES AND WATER LEVELS ARE NOT EXPECTED TO BE PROBLEMATIC IN AND
AROUND THE BAY OF FUNDY DUE TO THE CURRENTLY LOWER-AMPLITUDE TIDAL
CYCLE.
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
SLOPE - SOUTHWESTERN HALF. GALE WARNINGS ARE IN EFFECT FOR ALL
REMAINING MARINE AREAS COVERED BY THIS INFORMATION STATEMENT.
