TROPICAL CYCLONE INFORMATION STATEMENT UPDATED BY THE CANADIAN
HURRICANE CENTRE OF ENVIRONMENT CANADA AT 3:09 PM AST THURSDAY
10 NOVEMBER 2011.
---------------------------------------------------------------------
TROPICAL CYCLONE INFORMATION STATEMENT FOR:
NEWFOUNDLAND
NOVA SCOTIA.
FOR TROPICAL STORM SEAN.
THIS IS THE FINAL PLANNED STATEMENT BY THE CANADIAN HURRICANE
CENTRE ON THIS STORM.
TROPICAL STORM SEAN EXPECTED TO MERGE WITH STRONG COLD FRONT
WELL SOUTH OF NOVA SCOTIA - NO DIRECT AFFECTS EXPECTED.
---------------------------------------------------------------------
==DISCUSSION==
IT STILL APPEARS THAT SEAN WILL BECOME ABSORBED BY A STRONG COLD
FRONT MOVING OFF THE U.S. EASTERN SEABOARD. THE FRONT WILL TAP INTO
SOME EXTRA MOISTURE FROM THE STORM THAT COULD ENHANCE RAINFALLS OVER
NOVA SCOTIA AND NEWFOUNDLAND. HOWEVER, THE WIND CIRCULATION OF SEAN
IS EXPECTED TO BECOME FULLY ABSORBED INTO THE SOUTHERLY WINDS
ASSOCIATED WITH THE FRONT. A TIGHTER WIND/PRESSURE GRADIENT MAY
CROSS THE GRAND BANKS OFF NEWFOUNDLAND LATE FRIDAY OR EARLY SATURDAY
RELATED TO THE REMNANT OF SEAN, BUT MOST OF THE WIND WILL BE FROM THE
FRONT. WE DO NOT INTEND TO ISSUE ANY ADDITIONAL BULLETINS FROM THE
CANADIAN HURRICANE CENTRE UNLESS THERE IS A DRAMATIC CHANGE.
SPECIAL WEATHER STATEMENTS AND WARNINGS CAN BE FOUND AT
WEATHEROFFICE.GC.CA/WARNINGS AND STORM TRACK INFORMATION (FROM THE
MIAMI HURRICANE CENTRE) AT WEATHEROFFICE.GC.CA/HURRICANE (ALL IN
LOWER CASE).
PLEASE ALSO REFER TO THE PUBLIC AND MARINE FORECASTS AND WARNINGS
ISSUED BY ENVIRONMENT CANADA FOR YOUR AREA.

TROPICAL CYCLONE INFORMATION STATEMENT ISSUED BY THE CANADIAN
HURRICANE CENTRE OF ENVIRONMENT CANADA AT 9:04 AM AST THURSDAY
10 NOVEMBER 2011.
---------------------------------------------------------------------
TROPICAL CYCLONE INFORMATION STATEMENT FOR:
=NEW= NEWFOUNDLAND
=NEW= NOVA SCOTIA.
FOR TROPICAL STORM SEAN.
THE NEXT STATEMENT WILL BE ISSUED BY 3:00 PM AST.
WE ARE CURRENTLY MONITORING TROPICAL STORM SEAN WHICH IS
EXPECTED TO MERGE WITH AN APPROACHING COLD FRONT SOUTH OF
ATLANTIC CANADA.
---------------------------------------------------------------------
==DISCUSSION==
TROPICAL STORM SEAN MAY ATTAIN HURRICANE STATUS TODAY AS IT MOVES
NORTHEASTWARD TO THE WEST OF BERMUDA. A STRONG COLD FRONT IS
APPROACHING THE STORM FROM THE WEST AND IS EXPECTED TO
QUICKLY ABSORB IT AND EXTRACT THE MOISTURE NORTHWARD - FALLING OVER
NOVA SCOTIA AND NEWFOUNDLAND TOMORROW. CURRENT INDICATIONS ARE THAT
THE WIND CIRCULATION OF THE STORM WILL BECOME INDISTINCT AS IT
APPROACHES THE SOUTHERN MARINE FORECAST DISTRICT. WE WILL ASSESS
COMPUTER MODELS TODAY AND MAY ISSUE A DETAILED FORECAST THIS
AFTERNOON IF WE EXPECT THE STORM CIRCULATION TO AFFECT THE MARINE
FORECAST REGION MORE DIRECTLY THAN IS CURRENTLY INDICATED.
REGARDLESS, HIGH WIND, HEAVY RAINFALL AND UNSEASONABLY WARM
TEMPERATURES WILL OVERSPREAD ATLANTIC CANADA AND OFFSHORE WATERS
TOMORROW.
SPECIAL WEATHER STATEMENTS AND WARNINGS CAN BE FOUND AT
WEATHEROFFICE.GC.CA/WARNINGS AND STORM TRACK INFORMATION AT
WEATHEROFFICE.GC.CA/HURRICANE (ALL IN LOWER CASE).
PLEASE ALSO REFER TO THE PUBLIC AND MARINE FORECASTS AND WARNINGS

TROPICAL CYCLONE INFORMATION STATEMENT ISSUED BY THE CANADIAN
HURRICANE CENTRE OF ENVIRONMENT CANADA AT 5:34 PM AST WEDNESDAY
9 NOVEMBER 2011.
---------------------------------------------------------------------
TROPICAL CYCLONE INFORMATION STATEMENT FOR:
=NEW= NEWFOUNDLAND
=NEW= NOVA SCOTIA.
FOR TROPICAL STORM SEAN.
THE NEXT STATEMENT WILL BE ISSUED BY 9:00 AM AST THURSDAY.
CANADIAN HURRICANE CENTRE MONITORING TROPICAL STORM SEAN -
EXPECTED TO DISSIPATE AS TROPICAL ENTITY PRIOR TO ARRIVAL OVER
CANADIAN WATERS.
---------------------------------------------------------------------
==DISCUSSION==
TROPICAL STORM SEAN FORMED FROM AN ORIGINALLY NON-TROPICAL LOW
PRESSURE SYSTEM SOUTHWEST OF BERMUDA. THE STORM HAS BECOME ORGANIZED
TODAY AND MAY ATTAIN HURRICANE STATUS OVERNIGHT OR THURSDAY.
A STRONG COLD FRONT IS APPROACHING THE TROPICAL STORM FROM THE WEST
AND IS EXPECTED TO QUICKLY ABSORB IT AND EXTRACT THE MOISTURE
NORTHWARD - FALLING OVER NOVA SCOTIA AND NEWFOUNDLAND. WE DO NOT
EXPECT THE CORE OF THE STORM'S WIND TO LAST LONG ENOUGH TO AFFECT
CANADIAN WATERS DIRECTLY, SO WE ARE NOT PLANNING REGULAR BULLETINS
FROM THE CANADIAN HURRICANE CENTRE AT THIS TIME. HOWEVER, WE WILL
ISSUE AN UPDATE ON THE SITUATION THURSDAY MORNING. THE POSSIBILITY
OF THE STORM RETAINING ITS ENTITY INSIDE CANADIAN FORECAST WATERS
STILL EXISTS. REGARDLESS, HIGH WIND, HEAVY RAINFALL AND UNSEASONABLY
WARM TEMPERATURES WILL OVERSPREAD ATLANTIC CANADA AND OFFSHORE WATERS
ON FRIDAY.
SPECIAL WEATHER STATEMENTS AND RAINFALL WARNINGS CAN BE FOUND AT
WEATHEROFFICE.GC.CA/WARNINGS AND STORM TRACK INFORMATION AT
WEATHEROFFICE.GC.CA/HURRICANE (ALL IN LOWER CASE).

INTERMEDIATE TROPICAL CYCLONE INFORMATION STATEMENT UPDATED BY THE
CANADIAN HURRICANE CENTRE OF ENVIRONMENT CANADA AT 6:14 PM ADT MONDAY
3 OCTOBER 2011.
---------------------------------------------------------------------
INTERMEDIATE TROPICAL CYCLONE INFORMATION STATEMENT FOR:
NEWFOUNDLAND.
FOR POST-TROPICAL STORM OPHELIA.
THIS IS THE FINAL STATEMENT BY THE CHANCE OF ON THIS STORM.
AS OF 6:30 PM NDT THE LOW WAS LOCATED EAST OF THE NEWFOUNDLAND
MARINE DISTRICT - SOON TO BE ABSORBED BY A LARGE FRONTAL
SYSTEM.
---------------------------------------------------------------------
==DISCUSSION==
SUMMARY OF HURRICANE/POST-TROPICAL STORM OPHELIA.
OPHELIA MADE LANDFALL AROUND 9:30 AM LOCAL TIME ON MONDAY OCTOBER 3RD
IN THE VICINITY OF PLACENTIA ON THE AVALON PENINSULA'S SOUTHWEST
COAST OF NEWFOUNDLAND. THE STORM THEN MOVED ACROSS THE PENINSULA
PASSING JUST NORTH OF ST. JOHN'S THEN MOVED OVER THE NORTHERN GRAND
BANKS DURING THE AFTERNOON. THE LOWEST PRESSURE OVER LAND AT THE
TIME OF LANDFALL WAS NEAR 992 MB AS REPORTED BY A PRIVATELY-RUN
WEATHER STATION AT CAPE PINE NEAR ST. SHOTTS. THE MINIMUM PRESSURE
IN THE CENTRE OF THE STORM AT LANDFALL WAS NEAR 988 MB.
MAXIMUM WINDS AT LANDFALL WERE NEAR 100 OR 110 KM/H OVER THE OCEAN.
THE FORECAST TRACK HAD BEEN CORRECTED SLIGHTLY TO THE NORTHWEST BASED
ON COMPUTER MODELS AND SATELLITE IMAGES ANALYSED SUNDAY EVENING.
THE STRONGEST WINDS WITH THE STORM WERE TO THE RIGHT OF ITS
TRACK/CENTRE. THE HIGHEST WINDS REMAINED JUST OFFSHORE TO THE SOUTH
OF THE AVALON. WIND GUSTS TO 100 KM/H WERE RECORDED ALONG THE
IMMEDIATE COASTLINE WHILE INLAND GUSTS IN THE 80 TO 85 KM/H RANGE
WERE MEASURED. WINDS NOTICABLY DIMINISHED AS THE CENTRE PASSED OVER
SOME COMMUNITIES ON THE AVALON PENINSULA, THEN PICKED-UP AGAIN FROM
THE WEST OR NORTHWEST AS THE STORM MOVED AWAY. A FEW OF THOSE WIND
GUSTS GOT INTO THE UPPER 90 KM/H RANGE.
RAINFALL AMOUNTS RANGING FROM 25 TO 60 MILLIMETRES WERE RECORDED
ACROSS MUCH OF SOUTHEASTERN NEWFOUNDLAND. ST LAWRENCE RECEIVED 58
MILLIMETRES AND BONAVISTA 62 MILLIMETRES. CAPE RACE TO THE EAST AND
BURGEO TO THE WEST OF THE STORM REPORTED ONLY 4 AND 10 MILLIMETRES,
RESPECTIVELY. THIS WAS DUE IN PART TO THE DRY AIR THAT WRAPPED
AROUND THE STORM AS IT WAS UNDERGOING TRANSITION TO POST-TROPICAL,
AND ALSO DUE TO ITS RAPID SPEED OF TRAVEL THROUGH THE AREA.
THERE WERE SEVERAL REPORTS OF FLOODING IMPACTS WHICH RESULTED FROM
HEAVY DOWNPOURS MONDAY MORNING. RAINFALL RATES OF 20
MILLIMETRES/HOUR WERE OBSERVED OVER THE BURIN, CONNAIGRE AND
BONAVISTA PENINSULAS. AT LEAST ONE COMMUNITY, BELLEORAM, DECLARED A
STATE OF EMERGENCY FOR A 3-HOUR PERIOD AFTER HEAVY RAIN CAUSED
LOCALISED FLOODING. A NUMBER OF ROADWAYS WERE CLOSED TO TRAFFIC DUE
TO FLOODING, WASHOUT AND DEBRIS.
HERE ARE SOME UNOFFICIAL PRECIPITATION AMOUNTS AND MAXIMUM WIND GUSTS
AS OF 3 PM MONDAY:
RAINFALL PEAK WIND
(MILLIMETRES) (KM/H)
ST. PIERRE/MIQUELON 65 98
BONAVISTA 62 80
ST. LAWRENCE 58 70
ST. ALBAN'S 49 -
TERRA NOVA PARK 47 -
GANDER 27 -
ST. JOHN'S AIRPORT 27 78
ARGENTIA 24 72
ST. JOHN'S WEST 22 -
BURGEO 10 -
CAPE RACE 4 98
THE AXIS OF MAXIMUM WINDS EXTENDED FROM LAURENTIAN FAN TO JUST SOUTH
OF THE AVALON PENINSULA TO THE NORTHERN GRAND BANKS. THESE WINDS
CREATED SIGNIFICANT WAVES OF 14 METRES WITH PEAKS AT 22 METRES AT THE
LAURENTIAN FAN BUOY SUNDAY EVENING. THESE WAVES PROPAGATED NORTHWARD
DURING THE NIGHT AND REACHED THE SOUTH COAST OF NEWFOUNDLAND AT A
REDUCED AMPLITUDE MONDAY MORNING. SIGNIFICANT WAVES OF 5 TO 9 METRES
AND PEAK WAVES OF 10 TO 15 METRES WERE RECORDED AT THE MOUTH OF
PLACENTIA BAY AND AT BUOY 44251 RESPECTIVELY. THESE WAVES PROPAGATED
OVER THE GRAND BANKS DURING THE AFTERNOON AT A LESSER AMPLITUDE.
HIBERNIA REPORTED WAVES OF 5 METRES DURING THE MID-AFTERNOON.
CURIOUS SPECTATORS ATTRACTED BY THE WAVE ACTION WERE ENCOURAGED TO
STAY WELL AWAY FROM THE WAVE-BREAKING ZONES AS DANGEROUS SURF AND
RIPTIDE CONDITIONS WERE CREATED. THERE WAS SOME BEACHFRONT DEBRIS
WASH-UPS IN PRONE AREAS OF THE SOUTHERN AVALON AND BURIN PENINSULAS.
STORM SURGE WAS NOT A SIGNIFICANT FACTOR WITH OPHELIA - REGISTERING
NEAR 50 CM AT ARGENTIA AT LOW TIDE MONDAY MORNING. SINCE THE STORM
WAS MOVING SO FAST, THERE WAS LITTLE TIME FOR THE WIND TO CAUSE WATER
TO PILE-UP IN THE BAYS.
