3. PUBLIC WEATHER IMPACTS AND WARNINGS SUMMARY
HURRICANE WARNING IS IN EFFECT FOR DIGBY YARMOUTH AND SHELBURNE
COUNTIES IN NOVA SCOTIA. A TROPICAL STORM WARNING IS MAINTAINED
FOR QUEENS COUNTY OF NOVA SCOTIA LUNENBURG COUNTY ANNAPOLIS COUNTY
SAINT JOHN AND COUNTY AND GRAND MANAN AND COASTAL CHARLOTTE
COUNTY IN NEW BRUNSWICK FUNDY NATIONAL PARK MONCTON AND
SOUTHEAST NEW BRUNSWICK. WIND GUSTS OF 90 TO 130 KM/H CAN BE
EXPECTED OVER SOUTHWESTERN NOVA SCOTIA THIS EVENING AND EARLY
TONIGHT EXCEPT GUSTS 70 TO 100 OVER THE NEW BRUNSWICK SOUTHERN
SECTIONS.
THE ATLANTIC STORM PREDICTION CENTER HAS ISSUED A STORM SURGE
WARNING FOR HIGHER THAN NORMAL WATER LEVELS ALONG THE COAST OF
YARMOUTH AND SHELBURNE COUNTIES. THE COMBINATION OF STORM SURGE
AND WAVE SETUP ARE EXPECTED TO RESULT IN WATER LEVELS OF MORE
THAN 1.0 METRE ABOVE THE HIGH ASTRONOMICAL TIDE WHICH WILL BE
OCCURRING WITHIN A COUPLE OF HOURS OF THE STORM ARRIVING
THIS EVENING. BASED ON HISTORICAL PRECEDENTS THIS COMBINATION
COULD CAUSE SOME COASTAL FLOODING.

IT SHOULD BE EMPHASIZED THAT PORTIONS OF SOUTHWESTERN NOVA SCOTIA
AND SOUTHWESTERN NEW BRUNSWICK WILL LIKELY ENCOUNTER
TREE DAMAGE DURING THE STRONGEST WINDS OF KYLE EITHER THIS
EVENING OR OVERNIGHT. DURING SIMILAR EVENTS IN THE
PAST THESE WINDS HAVE RESULTED IN DOWNED POWER LINES AND DAMAGE TO
STRUCTURES DUE TO FALLEN TREES. ALL PREPARATIONS TO SECURE ANY LOOSE
OBJECTS SHOULD BE COMPLETED BY THIS TIME.

RAINFALL WARNINGS ARE IN EFFECT FOR ALL OF NEW BRUNSWICK
WHERE 50 TO 100 MILLIMETRES OF RAIN ARE EXPECTED WITH KYLE. THIS
IS IN ADDITION TO SIGNIFICANT RAINFALL AMOUNTS THAT FELL PRIOR TO
KYLE'S ARRIVAL. THE HEAVIEST RAINFALL WILL BE CONFINED WEST OF WHERE
KYLE EVENTUALLY MAKES LANDFALL. EMO NEW BRUNSWICK REMINDS THE PUBLIC
THAT RAINFALL IN THESE AMOUNTS OVER A SHORT PERIOD OF TIME CAN
RESULT IN A RAPID WATER LEVEL INCREASE IN STREAMS AND RIVERS
AND CAUSED LOCALIZED FLASH FLOODING.

RAINFALL WARNINGS ARE ALSO IN EFFECT FOR MUCH OF THE GASPÉ
PENINSULA AND SOUTHEASTERN SHORE OF THE ST LAWRENCE RIVER VALLEY
REGIONS OF QUÉBEC. THIS AREA WILL SEE RAINFALL AMOUNTS NEAR OR
EXCEEDING 50 MILLIMETRES AS POST TROPICAL STORM KYLE INTERACTS
WITH A FRONTAL ZONE OVERNIGHT AND INTO MONDAY.

ON ITS CURRENT TRACK KYLE WILL BE PASSING JUST WEST OF YARMOUTH NOVA
SCOTIA AT THE TIME OF HIGH TIDE IN YARMOUTH. THE RESULTING STORM
SURGE ON TOP OF THE DANGEROUS ROUGH SURF FROM KYLE MAY LEAD TO
SHORELINE EROSION AND DAMAGE TO THE COASTAL INFRASTRUCTURE
MAINLY IN YARMOUTH AND SHELBURNE COUNTIES.


4. MARINE WEATHER IMPACTS AND WARNINGS SUMMARY
THE GEORGES BANK BUOY REPORTED STRONG TO HURRICANE FORCE OF
69 KNOTS THIS AFTERNOON. THE STORM CENTRE PASSED WEST OF THE
BUOY WHICH REPORTED AN 11.0 M SIGNIFICANT WAVE HEIGHTS.

HURRICANE FORCE WIND WARNINGS ARE CONTINUED FOR GEORGES AND
BROWNS BANK AND FOR THE LURCHER MARINE AREA. STORM WARNINGS
ARE CONTINUED FOR FUNDY GRAND MANAN AND THE SOUTHWESTERN SHORE
WESTERN LAHAVE AND NORTHWESTERN WEST SCOTIAN SLOPE MARINE
AREA. GALE WARNINGS ARE IN EFFECT FOR MUCH OF EASTERN NOVA
SCOTIA WATERS AND GULF OF ST LAWRENCE WATERS.

5. TECHNICAL DISCUSSION FOR METEOROLOGISTS

A. ANALYSIS
REPORTS FROM BUOYS SATELLITES SHIPS AND LAND STATIONS INDICATES
THAT STORM TO HURRICANE FORCE WINDS EXISTS IN THE VICINITY
OF HURRICANE KYLE. AT 9 PM THIS EVENING THE ESTIMATED POSITION IS
JUST WEST OR NORTHWEST OF YARMOUTH NOVA SCOTIA AND TRACKING
TOWARDS THE NORTHEAST AT ABOUT 23 KNOTS OR 43 KM/H.

THE CLOUD SHIELD IS TAKING A COMA SHAPE WITH FRONTAL LIKE
CLOUD AND RAIN BAND TO THE EAST THEN NORTH THEN THE WESTERN
QUADRANT OF THE CENTRE. THIS IMPLIES RAPID TRANSITIONING
OF HURRICANE KYLE AT THIS TIME. THIS IS CONSISTENT
WITH PREVIOUS PROGNOSTICS REFERING TO THE EFFECT OF THE MUCH COLDER
WATER IN THE GULF OF MAINE. WINDS ARE ESTIMATED AT 65 KNOTS
WITH GUSTS TO 75 KNOTS AT THIS TIME.

B. PROGNOSTIC

KYLE IS EXPECTED TO TRACK NORTHEASTWARD PASSING NEAR THE WEST
COAST OF YARMOUTH AND DIGBY COUNTIES NOVA SCOTIA LATE THIS
SUNDAY EVENING THEN ACROSS THE BAY OF FUNDY BEFORE MAKING
LANDFALL JUST EAST OF SAINT JOHN NEW BRUNSWICK AFTER MIDNIGHT
OR IN THE EARLY HOURS OF MONDAY MORNING. KYLE IS EXISTING
BETWEEN AN UPPER TROUGH TO THE WEST AND AN UPPER RIDGE OVER
THE ATLANTIC.
WE KEEP KYLE AT 65 KNOTS AT HURRICANE FORCE WINDS BECAUSE OF ITS
PRESENT INTENSITY AND ITS FAST MOVEMENT. THE MODELS CONTINUE
TO BE CONSISTENT ON MAINTAINING A BAROCLINIC LOW NEAR OUR TRACK
BUT WE CONTINUE TO USE SHORT TERM ANALYSIS AND DIAGNOSTIC AS WELL
AS THE ENSEMBLE AND MIAMI FOR GUIDANCE.

KYLE IS STILL EXPECTED TO WEAKEN OVER THE COLD WATER OF
THE BAY OF FUNDY THEN RAPIDLY FINISH ITS TRANSITION INTO
A POST-TROPICAL LOW AS IT MOVES OVER SOUTHEASTERN NEW BRUNSWICK.
IT WILL CONTINUE TO WEAKEN OVER THE GULF OF ST LAWRENCE
THEN DISSIPATE OVER THE EASTERN QUÉBEC NORTH SHORE AT THE
END OF THE FORECAST PERIOD.

C. PUBLIC WEATHER
THE HEAVIEST RAINFALL WILL BE WEST OF THE STORM PATH AND COULD
BE UPWARDS TO 100 MM. THIS HEAVIEST RAIN COULD FALL IN A SHORT
PERIOD OF TIME INCREASING THE THREAT OF LOCALIZED FLOODING.
THIS RAIN IS ON TOP OF ANY AMOUNTS THAT FELL PREVIOUSLY.

D. MARINE WEATHER

CHC TRAPPED FETCH MODEL INDICATES NOTHING HIGHER THAN 8 METRES
MOVING INTO CANADIAN WATERS BUT THIS IS BASED ON THE SHIFTED
TRACK AND LACK OF ALIGNMENT WITH PREVIOUSLY DEVELOPED WAVES.
HOWEVER A SIGNIFICANT WAVE OF 10 METRES IS NOT FAR FETCHED.
