==DISCUSSION==  
 
FOR POST-TROPICAL STORM DORIAN.  
 
THIS IS A SPECIAL METEOROLOGICAL SUMMARY FOR POST-TROPICAL STORM  
DORIAN.  
 
THIS IS THE FINAL INFORMATION STATEMENT FOR THIS STORM.  
 
1. FULL DISCUSSION OF THE EVENT.  
 
ON AUGUST 23RD, A TROPICAL WAVE FORMED BETWEEN THE CAPE VERDE  
ISLANDS AND THE LESSER ANTILLIES. ONE DAY LATER ON AUGUST 24TH, THE  
NATIONAL HURRICANE CENTER IN MIAMI DECLARED THE SYSTEM A TROPICAL  
DEPRESSION AND NOT LONG AFTER TROPICAL STORM DORIAN. THE STORM  
REMAINED RELATIVELY WEAK UNTIL AUGUST 28TH, WHEN IT REACHED  
HURRICANE STATUS AND MADE LANDFALL IN THE US VIRGIN ISLANDS. A FEW  
DAYS AFTER, DORIAN BEGAN TO RAPIDLY INTENSIFY AND REACHED CATEGORY 5  
STATUS ON SEPTEMBER 1ST AS IT APPROACHED THE NORTHWESTERN BAHAMAS.  
DORIAN MADE LANDFALL ON ELBOW BAY WITH WINDS OF 295 KM/H. THE NEXT  
DAY DORIAN MOVED OVER GRAND BAHAMA AND STALLED JUST NORTH OF THE  
ISLAND FOR A STAGGERING 36 HOURS. DORIAN WEAKENING TO A CATEGORY 2  
STORM WHILE STATIONARY BEFORE FINALLY MOVING OFF TO THE NORTHEAST  
TOWARDS FLORIDA. DORIAN CAUSED CATASTROPHIC DAMAGE TO THE  
NORTHWESTERN BAHAMAS, MAKING IT THE STRONGEST HURRICANE TO IMPACT  
THAT REGION SINCE MODERN RECORDS BEGAN.  
 
ON SEPTEMBER 3RD, DORIAN BEGAN MOVING NORTHWESTWARD TOWARDS FLORIDA  
BUT MADE A TURN MORE NORTHWARD AND REMAINED OFFSHORE, PARALLELING  
THE FLORIDA COAST. THE CANADIAN HURRICANE CENTRE BEGAN ISSUING  
TROPICAL STATEMENTS ON SEPTEMBER 4TH AS MODEL CONSENSUS BECAME CLEAR  
THAT THE STORM WAS GOING TO HAVE AN IMPACT ON ATLANTIC CANADA.  
 
ON SEPTEMBER 5TH, DORIAN REGAINED SOME STRENGTH BACK TO A CATEGORY 3  
HURRICANE WHILE GRAZING THE CAROLINA COASTS, MAKING LANDFALL OVER  
CAPE HATTERAS ON THE MORNING OF SEPTEMBER 6TH. DORIAN THEN GOT  
PICKED UP IN THE MID LATITUDE WESTERLIES AND BEGAN ACCELERATING  
NORTHEASTWARD TOWARDS ATLANTIC CANADA. THE CANADIAN HURRICANE CENTRE  
BEGAN ISSUING HURRICANE AND TROPICAL STORM WATCHES AND WARNINGS  
EARLY ON SEPTEMBER 6TH.  
 
EARLY ON SEPTEMBER 7TH, DORIAN WEAKENED TO A CATEGORY 1 AS IT  
APPROACHED THE SOUTHWESTERN MARINE WATERS. DORIAN BEGAN  
TRANSITIONING INTO A POST-TROPICAL SYSTEM AS THE WIND FIELD EXPANDED  
CONSIDERABLY FROM THE STORM CENTRE AND THE RAIN SHIFTED TO THE LEFT  
OF THE TRACK. CONDITIONS OVER NOVA SCOTIA QUICKLY DETERIORATED MID  
MORNING ON THE 7TH AS TORRENTIAL RAINS AND STRONG WIND GUSTS SPREAD  
FURTHER NORTH AND EAST. DORIAN BEGAN INTERACTING WITH A MID TO HIGH  
LEVEL TROUGH THAT WAS APPROACHING THE MARITIMES AND, WITH THE HELP  
OF BAROCLINIC INFLUENCES, WAS ABLE TO INCREASE IN STRENGTH JUST AS  
IT APPROACHED THE SOUTHWESTERN SHORE OF NOVA SCOTIA. DORIAN WAS  
DESIGNATED POST-TROPICAL AT 6 PM ADT, AND SOON AFTER MADE LANDFALL  
IN SAMBRO CREEK, SOUTH OF HALIFAX AT NEAR 7PM AS A HURRICANE  
STRENGTH POST-TROPICAL CYCLONE WITH A PRESSURE OF 958 MILLIBARS.  
 
DORIAN CONTINUED QUICKLY TOWARD THE NORTHEAST, TRACKING OVER  
NORTHERN NOVA SCOTIA, JUST EAST OF PRINCE EDWARD ISLAND, AND OVER  
THE GULF OF ST. LAWRENCE BY THE MORNING OF SEPTEMBER 8TH. DORIAN  
WEAKENED TO TROPICAL STORM STRENGTH AS IT MOVED NORTHEASTWARD  
TOWARDS THE GREAT NORTHERN PENINSULA OF NEWFOUNDLAND THE EVENING OF  
SEPTEMBER 8TH. THE STORM CONTINUES TO TRACK OUT OVER THE LABRADOR  
SEA AND TOWARDS EUROPE.  
 
THE EFFECTS OF DORIAN WERE FELT OVER A LARGE AREA DUE TO THE  
EXPANDING WIND FIELD AND RAIN SHIELD TO THE LEFT OF DORIAN'S TRACK.  
NOVA SCOTIA ENCOUNTERED DESTRUCTIVE HURRICANE FORCE WIND GUSTS OF UP  
TO 145 KM/H ALONG THE ATLANTIC COAST FROM YARMOUTH TO CAPE BRETON.  
PEAK POWER OUTAGES OVER NOVA SCOTIA, PRINCE EDWARD ISLAND AND NEW  
BRUNSWICK REACHED OVER 500,000 CUSTOMERS. DAMAGE INCLUDED MANY  
UPROOTED TREES, DOWNED POWER LINES, AND FLYING DEBRIS. A  
CONSTRUCTION CRANE FELL FROM A BUILDING IN DOWNTOWN HALIFAX JUST  
PRIOR TO THE STORM MAKING LANDFALL. STRONG WINDS WITH GUSTS UP TO  
100 KM/H WERE ALSO EXPERIENCED OVER EASTERN NEW BRUNSWICK, PRINCE  
EDWARD ISLAND, THE MAGDALEN ISLANDS, WESTERN AND NORTHEASTERN  
NEWFOUNDLAND, AND THE LOWER NORTH SHORE QUEBEC.  
 
A HEAVY SWATH OF RAIN JUST TO THE LEFT OF THE TRACK PRODUCED  
RAINFALL RATES OF OVER 30 MM/H OVER CENTRAL AND NORTHERN NOVA  
SCOTIA. TOTAL RAINFALL AMOUNTS OF 50 TO 140 MM WERE SEEN OVER SOUTH  
AND EASTERN NEW BRUNSWICK, SOUTHWESTERN TO CENTRAL NOVA SCOTIA, AND  
WESTERN PRINCE EDWARD ISLAND.  
 
FINALLY, STORM SURGE AND ROUGH POUND SURF HAD A CONSIDERABLE IMPACT  
FOR AREAS ALONG THE ATLANTIC COAST OF NOVA SCOTIA AND SOUTHWESTERN  
NEWFOUNDLAND, NORTHUMBERLAND STRAIT, THE MAGDALEN ISLANDS, AND PARTS  
OF THE LOWER NORTH SHORE QUEBEC FROM BLANC SABLON TO CHEVERY. THE  
HALIFAX TIDE GUAGE REPORTED A WATER LEVEL OF 2.9 METRES WITH A SURGE  
OF 1.5 METRES. LOWER ESCUMINAC ON THE EAST COAST OF NEW BRUNSWICK  
REACHED 2.6 METRES WHICH BROKE THEIR PRIOR RECORD OF 2.44 METRES.  
MARINE WAVES WERE ALSO SUBSTANTIAL AS THE STORM TRACKED OVER GEORGES  
BANK NORTHEAST ALONG THE ATLANTIC COAST OF NOVA SCOTIA TOWARD THE  
SOUTHWESTERN COAST OF NEWFOUNDLAND. THE SLOPE WATERS EXPERIENCED
