3. PUBLIC WEATHER IMPACTS AND WARNINGS SUMMARY POST-TROPICAL STORM
HANNA IS BRINGING PERIODS OF HEAVY RAIN
TO CAPE BRETON AND IS SPREADING INTO NEWFOUNDLAND. RAINFALL
WARNINGS ARE IN EFFECT FOR PRINCE EDWARD ISLAND NORTHEASTERN
NOVA SCOTIA AND SOUTHERN AND CENTRAL NEWFOUNDLAND. TOTAL
RAINFALLS OF 40 TO 60 MM ARE FORECAST FOR REGIONS OF
NEWFOUNDLAND AND LOCALLY HIGHER AMOUNTS ARE POSSIBLE. WINDS
GUSTING UP TO 70 KM/H CAN BE EXPECTED OVER EASTERN NOVA SCOTIA
MOSTLY NEAR THE ATLANTIC COAST.

THERE HAVE BEEN REPORTS OF LOCALIZED FLOODING ACROSS SOUTHERN
NEW BRUNSWICK AND NORTHERN NOVA SCOTIA AND NUMEROUS REPORTS OF
DOWNED TREE BRANCHES AND SOME POWER OUTAGES.

4. MARINE WEATHER IMPACTS AND WARNINGS SUMMARY
GALES ARE FORECAST OVER MARITIME AND NEWFOUNDLAND WATERS SOUTH
OF THE TRACK OF POST-TROPICAL STORM HANNA FOR THE REMAINDER OF
THE AFTERNOON AND TONIGHT. GALES WILL PERSIST OVER SOUTHERN
EASTERN WATERS OF NEWFOUNDLAND ON MONDAY.
WAVE HEIGHTS ASSOCIATED WITH THESE WINDS HAVE REACHED 5 TO 6
METRES OVER WESTERN AREAS AND WILL SPREAD EASTERN TONIGHT.

5. TECHNICAL DISCUSSION

A. ANALYSIS
THE CENTRE OF HANNA IS OVER THE NORTHUMBERLAND STRAIT AND IS
WELL PLACED BY SURFACE OBSERVATIONS. HANNA HAS BEEN A TYPICAL
AND WELL BEHAVED EXTRA-TROPICAL SYSTEM. LATEST RADAR DATA
SHOWS THE BULK OF THE HEAVIEST RAIN IS LEFT OF THE STORM'S
TRACK AND THE STRONGEST WINDS HAVE BEEN OBSERVED TO THE RIGHT
OF HANNA'S TRACK.

B. PROGNOSTIC
THE GREATEST CONCERN WITH POST-TROPICAL HANNA IS RAINFALL.
COMPUTER MODELS HAVE BEEN VERY CONSISTENT WITH REGARDS TO THE
TRACK AND INTENSITY OF HANNA..WITH THE CONSENSUS TAKING THE
CENTRE OF POST-TROPICAL HANNA ALONG A PATH THROUGH THE GULF
OF ST LAWRENCE TO CLIP THE NORTHERN EDGE OF CAPE BRETON THIS
EVENING AND AND ACROSS NEWFOUNDLAND TONIGHT AND THEN MOVING
ALONG EASTERWARD WITH THE 500 MB FLOW ON MONDAY. A SHORTWAVE
TROUGH IS FORECAST TO BEGIN INTERACTING WITH THE REMNANTS OF
HANNA IN ABOUT 24 HOURS AND FORM A TRAILING BAROCLINIC STORM
OVER THE NORTH ATLANTIC.

Extratropical Storm Hanna Regional Warnings; New Warning Issued for New Brunswick Update 2

Emergency Measures Organization

Flash flood warning issued (08/09/06)

NB 1278

Sept. 6, 2008

FREDERICTON (CNB) - The following flash flood warning is issued by the Emergency Measures Organization on Saturday, Sept. 6:

Tropical Storm Hanna will bring wind and heavy rain to Atlantic Canada on Sunday and Monday, Sept. 7 and 8. Significant rainfall will occur with the greatest amounts in the southern half of New Brunswick.

Environment Canada advises that rainfall of up to 80 mm (three inches) is probable and local amounts of 100mm (four inches) are possible. Environment Canada is not forecasting a storm surge for this event; coastal areas, however, will experience high surf.

Rainfall in these amounts can result in rapid water level increases in streams and rivers and localized flash flooding. Power outages are also possible.

People living or working along watercourses or the southern and eastern coastlines of the province should take steps to protect their property and remain on alert until the storm has passed.

People should be particularly cautious in coastal areas because of high winds, heavy rain and dangerous surf. This advisory will be of particular concern to those who have been affected by similar storms in the past.

More information is available at:

5. TECHNICAL DISCUSSION FOR METEOROLOGISTS

A. ANALYSIS
THE CENTRE OF HANNA IS OVER THE GULF OF MAINE. THE LATEST
RADAR DATA SHOWS THE BULK OF THE HEAVIEST RAIN IS LEFT
OF THE STORM'S TRACK WHICH IS TYPICAL FOR EXTRATROPICAL
TRANSITIONING SYSTEMS. A COUPLE OF AUTOMATIC REPORTING
STATIONS - POINT LEPREAU AND MECHANIC SETTLEMENT IN SOUTHERN
NEW BRUNSWICK - HAVE OBSERVED RAINFALL RATES IN EXCESS OF 30
MILLIMETERS PER HOUR IN THE PAST 3 HOURS. THE STRONGEST WINDS
OBSERVED ARE TO THE RIGHT OF HANNA'S TRACK..ALSO TYPICAL OF
EXTRATROPICAL TRANSITION.

B. PROGNOSTIC
THE GREATEST CONCERN WITH POST-TROPICAL HANNA IS RAINFALL.
COMPUTER MODELS ARE STILL CONSISTENT WITH REGARDS TO THE TRACK
AND INTENSITY OF HANNA..WITH THE CONSENSUS TAKING THE CENTRE
OF POST-TROPICAL HANNA ALONG A PATH IN THE VICINITY OF THE BAY
OF FUNDY AROUND NOON TODAY AND OVER CABOT STRAIT NEAR MIDNIGHT
TONIGHT. POST-TROPICAL HANNA WILL THEN TRACK NORTHEASTWARD TO
LIE NEAR THE EAST COAST OF NEWFOUNDLAND MONDAY MORNING. A
SHORTWAVE TROUGH INTERACTING WITH POST-TROPICAL HANNA WILL CAUSE
THE SYSTEM TO SLOW DOWN AND INTENSIFY MONDAY. MONDAY NIGHT
POST-TROPICAL HANNA WILL EXIT CANADIAN WATERS AS AN INTENSIFYING
BAROCLINIC STORM OVER THE NORTH ATLANTIC.

3. PUBLIC WEATHER IMPACTS AND WARNINGS SUMMARY
POST-TROPICAL STORM HANNA WILL BRING PERIODS OF HEAVY
RAIN TO THE MARITIMES TODAY. RAINFALL WARNINGS HAVE BEEN ISSUED
BY THE ATLANTIC STORM PREDICTION CENTRE FOR SOUTHERN
NEW BRUNSWICK..PEI AND NORTHERN AND WESTERN NOVA SCOTIA WITH 40 TO
80 MM LIKELY.. WITH SOME COMPUTER GUIDANCE SUGGESTING NEAR 100 MM
POSSIBLE IN SOME AREAS. GUSTY WINDS CAN BE EXPECTED OVER NOVA
SCOTIA..GUSTING TO AROUND 70 KM/H. WINDS SHOULD NOT BE MUCH OF A
FACTOR OVER NEW BRUNSWICK.

RAIN AT TIMES HEAVY WILL BEGIN OVER SOUTHERN NEWFOUNDLAND
TODAY AND WILL PERSIST OVER PORTIONS OF THE ISLAND TONIGHT AND
MONDAY. GUSTY NORTHERLY WINDS CAN BE EXPECTED OVER EASTERN
PORTIONS OF NEWFOUNDLAND AS POST-TROPICAL HANNA MOVES EAST OF
THE ISLAND ON MONDAY. RAINFALL WARNINGS HAVE BEEN ISSUED BY THE
NEWFOUNDLAND AND LABRADOR WEATHER OFFICE FOR PORTIONS OF
NEWFOUNDLAND AS A RESULT.

4. MARINE WEATHER IMPACTS AND WARNINGS SUMMARY
GALES ARE FORECAST OVER MARITIME WATERS SOUTH OF THE TRACK OF
POST-TROPICAL STORM HANNA TODAY. WAVE HEIGHTS ASSOCIATED WITH
THESE WINDS SHOULD REACH NEAR 5 METRES IN THE OFFSHORE REGIONS
BY LATE SUNDAY.

GALES WILL SPREAD INTO EASTERN AND SOUTHERN NEWFOUNDLAND WATERS
TONIGHT AND MONDAY.

5. TECHNICAL DISCUSSION FOR METEOROLOGISTS

A. ANALYSIS
THE CENTRE OF HANNA IS OVER SOUTHEASTERN CONNECTICUT. THE LATEST
RADAR DATA SHOWS THE BULK OF HEAVIEST RAIN BANDS HAVE SHIFTED LEFT
OF THE STORM'S TRACK WHICH IS TYPICAL FOR EXTRATROPICAL
TRANSITIONING SYSTEMS. THE STRONGEST WINDS OBSERVED ARE TO THE
RIGHT OF HANNA'S TRACK..ALSO TYPICAL OF EXTRATROPICAL TRANSITION.

B. PROGNOSTIC
THE GREATEST CONCERN WITH POST-TROPICAL HANNA WILL BE RAINFALL.
COMPUTER MODELS ARE STILL CONSISTENT WITH REGARDS TO THE TRACK
AND INTENSITY OF HANNA..WITH THE CONSENSUS TAKING THE CENTRE
OF POST-TROPICAL HANNA ALONG A PATH IN THE VICINITY OF THE BAY
OF FUNDY AROUND NOON TODAY AND OVER CABOT STRAIT NEAR MIDNIGHT
TONIGHT. POST-TROPICAL HANNA WILL THEN TRACK NORTHEASTWARD TO
LIE NEAR THE EAST COAST OF NEWFOUNDLAND MONDAY MORNING. A
SHORTWAVE TROUGH INTERACTING WITH POST-TROPICAL HANNA WILL CAUSE
THE SYSTEM TO SLOW DOWN AND INTENSIFY MONDAY. MONDAY NIGHT
POST-TROPICAL HANNA WILL EXIT CANADIAN WATERS AS AN INTENSIFYING
BAROCLINIC STORM OVER THE NORTH ATLANTIC.

CYCLONE PHASE SPACE DIAGRAMS CONTINUE SUGGESTING EXTRATROPICAL
TRANSITION WILL BE COMPLETE PRIOR TO IT REACHING CANADIAN WATERS.
THIS INDICATES THAT THE WIND FIELD SHOULD BEHAVE GENERALLY LIKE A
TRADITIONAL BAROCLINIC CYCLONE AS IT CROSSES THE MARITIMES.
