Default Hurricane Earl - Atlantic Canada Threat

Hurricane Earl is currently located east of the Leeward Islands as a category one hurricane.

Models are really starting to come into agreement with where Earl is going, and some models are hinting at a Nova Scotia landfall next weekend.

Current NHC track takes Earl around the Delmarva Peninsula by Friday at 8am as a category three major hurricane. It could landfall anywhere from Long Island, NY to Cape Cod, MA then shoot northeast along the jet back into open waters, then landfall again around the Bay of Fundy area. If this were to occur, Earl would undergo considerable weakening as he would interact with land then emerge back over waters which would be very cold temperature wise. This could even lead to a subtropical storm or hurricane.

Another scenario is that Earl could just skirt Cape Cod, MA then speed up northeast and slam into Nova Scotia, or just brush Nova Scotia while remaining over open waters the possibly affecting NFLD.

The EURO for 24 hours now has been consistent with a Nova Scotia landfall around the Bay of Fundy area as a minimal hurricane, category one or two. The EURO also keeps Earl largely offshore New England, which would allow Earl to maintain hurricane strength.

Below is a zoomed in graphic of the EURO long range forecast for Sat. Sept. 4.10 at 00z.

Will be interesting to monitor the progress of Earl to see how Atlantic Canada may be impacted.

12z EURO run has changed Earl's track back to the west for 120 hours. EURO has also increased the pressure to 947mb, which means a more intense hurricane. Looks like Earl just misses Cape Cod on this run then slams into Nova Scotia shortly after.

The NHC has adjusted the track at 11am to include a possible direct landfall on Nova Scotia as at least a category two hurricane.

3. PUBLIC WEATHER IMPACTS AND WARNINGS SUMMARY NO WARNINGS TO SPEAK
OF HERE AS EARL IS NOT EXPECTED TO IMPACT ATLANTIC CANADA FOR SEVERAL
DAYS. HOWEVER, GIVEN THE CURRENT TRACK WARNINGS ARE LIKELY TOWARD THE
END OF THE WEEK.

4. MARINE WEATHER IMPACTS AND WARNINGS SUMMARY CURRENTLY NO WARNINGS
IN EFFECT. AS EARL APPROACHES THE MARITIMES,
 WARNINGS WILL LIKELY BE ISSUED LATER THIS WEEK..AND FOR PORTIONS OF
THE NEWFOUNDLAND MARINE DISTRICT THIS COMING WEEKEND.

5. TECHNICAL DISCUSSION FOR METEORLOGISTS

A. ANALYSIS EARL HAS BEEN WOBBLING TO THE WEST-NORTHWEST FOR THE PAST
SEVERAL HOURS AS IT NEARS THE WESTERN EDGE OF THE SUB-TROPICAL RIDGE
OVER THE ATLANTIC OCEAN. THE EYE OF EARL HAS BECOME OBSCURED ON BOTH
VISIBLE AND INFRARED SATELLITE IMAGERY DUE TO THE EYEWALL
DISPLACEMENT CYCLE. WATER VAPOR IMAGERY NORTHWEST OF EARL SHOWS AN
AREA OF DRY AIR WHICH MAY INHIBIT FURTHER INTENSIFICATION.

B. PROGNOSTIC FOLLOWING NHC ON BOTH TRACK AND INTENSITY.

 EARL IS TRACKING WEST-NORTHWESTWARD NORTH OF PUERTO RICO AS IT IS
BEEING STEERED BY THE RIDGE IN THE SOUTH ATLANTIC. AS IT NEARS THE
WESTERN EDGE OF THE RIDGE, EARL WILL BEGIN TO TURN MORE NORTHWARD AND
THEN NORTHEASTWARD IN A COUPLE OF DAYS, IN RESPONSE TO AN APPROACHING
TROUGH TO THE WEST. MODEL GUIDANCE IS TIGHTLY CLUSTERED IN THE 48-72
HOUR TIMEFRAME, HOWEVER THEY BECOME DIVERGENT THEREAFTER. THERE
REMAINS A WIDE RANGE OF TRACK SCENERIOS LATER IN THE WEEK, RANGING
FROM A POTENTIAL LANDFALL AS FAR WEST AS MAINE AND AS FAR EAST AS
EASTERN NEWFOUNDLAND.

 AT THIS POINT...PROBABLISTIC COMPUTER MODELS GENERALLY SHOW ABOUT A
60 PERCENT CHANCE OF AT LEAST GALE-FORCE WINDS (60-70 KM/H) OVER LAND
IN NOVA SCOTIA. ALTHOUGH THE OFFICIAL TRACK INDICATES A
 CATEGORY-ONE HURRICANE LANDFALL IN WESTERN NOVA SCOTIA..THIS ONLY
REFLECTS THE AVERAGE OF MANY SCENARIOS AND LANDFALL LOCATIONS 3 TO 4
DAYS AWAY. THE STATISTICAL GUIDANCE INDICATES ABOUT A 75 PERCENT
CHANCE OF EARL ENTERING CANADIAN FORECAST WATERS AS A HURRICANE AND
30-40 PERCENT CHANCE OF A LANDFALLING HURRICANE IN NOVA SCOTIA.

C. PUBLIC WEATHER TOO EARLY AT THIS TIME TO GIVE DETAILED IMPACTS DUE
TO UNCERTAINTY IN THE CURRENT TRACK AND INTENSITY TREND.

D. MARINE WEATHER TOO EARLY AT THIS TIME TO GIVE DETAILED IMPACTS DUE
TO UNCERTAINTY IN THE CURRENT TRACK AND INTENSITY TREND.

EARLIER THIS MORNING.  IT IS LIKELY THESE WATCHES.. INCLUDING
HURRICANE WATCHES.. WILL BE EXTENDED TO OTHER REGIONS OF NOVA
SCOTIA..NEW BRUNSWICK.. AND PRINCE EDWARD ISLAND LATER TODAY.

LANDFALL OF EARL MAY OCCUR IN VICINITY OF WESTERN NOVA SCOTIA
TO THE FUNDY COAST OF NEW BRUNSWICK EARLY SATURDAY MORNING. THE
DETAILS OF THE PUBLIC IMPACTS WILL BE ASSESSED FURTHER LATER TODAY
AND TONIGHT. IT IS VERY LIKELY THAT HIGH WIND AND HEAVY RAIN WILL
AFFECT THE MARITIMES ON SATURDAY. RAINFALL AMOUNTS AND WIND SPEED
INFORMATION WILL APPEAR IN OUR NEXT BULLETIN AT 3.00 PM.

THE PUBLIC SHOULD CERTAINLY PAY CLOSE ATTENTION REGARDING WEEKEND
PLANS THAT MAY BE SENSITIVE TO HIGH WIND AND HEAVY RAIN CONDITIONS.
IT IS EMPHASIZED THAT UPDATED FORECASTS SHOULD BE CONSULTED FOR THE
LATEST FORECAST DECISIONS AND RATIONALE. THESE ARE ISSUED FOUR
TIMES DAILY.


4. MARINE WEATHER IMPACTS AND WARNINGS SUMMARY

GALE WARNINGS ARE IN EFFECT FOR BROWNS BANK AND GEORGES BANK
WITH THE APPROACH OF EARL FRIDAY EVENING. IT IS VERY LIKELY
THAT THESE GALES WILL BE EXPANDED TO OTHER MARINE AREAS
AND THAT STORM WARNINGS AND HURRICANE FORCE WIND WARNINGS WILL
BE REQUIRED FOR PORTIONS OF THE ATLANTIC CANADIAN MARINE DISTRICT.
THESE WARNINGS WOULD BE ISSUED WITH 3.00 AM FRIDAY MORNING MARINE
FORECAST.

OCEAN SWELL WILL BEGIN TO REACH THE NOVA SCOTIA COAST TODAY WELL
AHEAD OF EARL.

WITH THE ARRIVAL OF EARL HIGH WAVES AND POUNDING SURF CAN
EXPECTED ALONG THE COAST OF THE SOUTHERN MARITIMES FRIDAY NIGHT AND
SATURDAY MORNING AND ALONG THE GULF OF ST. LAWRENCE COASTLINES
SATURDAY AFTERNOON AND EVENING.

HIGH WATER LEVELS AT THE COAST COULD BE AN ISSUE IF THE ARRIVAL
OF EARL IS TIMED WITH HIGH TIDE SATURDAY MORNING. THIS TIMING
WILL BE ASSESSED FURTHER AS WE GET CLOSER TO EARL'S ARRIVAL.


5. TECHNICAL DISCUSSION FOR METEORLOGISTS

A. ANALYSIS

SATELLITE IMAGERY SHOWS EARL WITH DISTINCT EYE AND CLASSIC OUTFLOW
PATTERN.  THE MOTION CONTINUES WITH ITS NORTHWESTWARD TRACK.  IT WAS
NOTED THAT BOUY 41047 REPORTED 9.6 METRE SEAS 100 NAUTICAL MILES
DUE EAST OF EARL.

B. PROGNOSTIC

EARL IS ROUNDING THE WESTERNMOST FLANK OF THE SUBTROPICAL RIDGE
HENCE WILL GRADUALLY TAKE ON A MORE NORTHWARD MOTION THROUGH THE
DAY.  THEREAFTER IT WILL BE INCREASINGLY GUIDED BY AN UPPER TROUGH
MOVING THROUGH THE GREAT LAKES.  THIS WILL CAUSE IT TO ACCELERATE
THROUGH ATLANTIC CANADA AS IT WEAKENS.  GIVEN THE HIGH POTENTIAL
TEMPERATURES OF THE AIRMASS OVER THE MARITIMES EARL MAY CONTINUE TO
HOLD ONTO ITS TROPICAL CHARACTERISTICS WELL INTO OUR REGION.  AS
POINTED OUT IN PREVIOUS MESSAGES.. WATER TEMPERATURES SOUTH OF NOVA
SCOTIA ARE ABOVE NORMAL BY 2 TO 4 DEGREES AND HAVE BEEN PERSISTENTLY
WARM DURING THE LATTER PART OF AUGUST.  THIS FACTOR WILL PLAY INTO
OUR FORECAST OF INTENSITY AS THE STORM MOVES OVER THOSE WATERS.
ALSO EARL WILL BE MOVING INTO A PRE-EXISTING TROPICAL AIRMASS AS IS
BEING EXPERIENCED OVER EASTERN CANADA RECENTLY. THAT COULD PERMIT
EARL TO RETAIN MORE TROPICAL CHARACTERISTICS AS IT ENTERS OUR REGION.

ULTIMATELY.. THE GREAT LAKES TROUGH WILL ADVANCE THROUGH EASTERN
CANADA AND STEADILY DRAIN EARL OF ITS ENERGY AS EARL BECOMES
GRADUALLY INCORPORATED INTO THIS FEATURE.  FRICTIONAL DEGRADATION IS
ANOTHER FACTOR WHICH WILL WEAKEN EARL.

A MULTITUDE OF NUMERICAL MODELS CONTINUE TO SHOW LITTLE SIGNIFICANT
CHANGE ON EARL'S FORECAST TRACK TOWARD ATLANTIC CANADA.  AS A
RESULT.. OUR CONFIDENCE IS INCREASING THAT EARL WILL MOVE INTO
SOUTHERN NOVA SCOTIA SATURDAY MORNING.  HOWEVER.. OUR EXPERIENCE
SHOWS THAT WE MUST CAUTIOUS AT THE SAME TIME.  THOUGH OUR ENVELOPE
OF POSSIBILIIES ON EARL'S TRACK IS NARROWING.. EARL COULD END
UP AS FAR WEST AS WESTERN NEW BRUNSWICK OR AS FAR EAST AS EASTERN
MAINLAND NOVA SCOTIA.

THE OFFICIAL TRACK MAP POSTED ON OUR WEBSITES.. ALTHOUGH SPECIFIC IN
TERMS OF A LINE MARKED WITH STORM POSITIONS AT SPECIFIC TIMES AND
SHOWING EARL AS A LANDFALLING CATEGORY-ONE HURRICANE..SIMPLY
REPRESENTS THE AVERAGE OF MANY FACTORS.

PROBABILISTIC COMPUTER MODELS GENERALLY SHOW ABOUT A 90 PERCENT
CHANCE OF AT LEAST GALE-FORCE WINDS (60 TO 70 KM/H) OVER LAND IN
NOVA SCOTIA. OUR STATISTICAL GUIDANCE INDICATES ABOUT AN 90 PERCENT
CHANCE OF EARL ENTERING CANADIAN FORECAST WATERS AS A HURRICANE..AND
50 TO 60 PERCENT CHANCE OF A LAND FALLING HURRICANE IN NOVA SCOTIA
OR NEW BRUNSWICK. THERE IS ABOUT A 20 PERCENT CHANCE OF EARL BEING
AT HURRICANE STATUS AFTER CROSSING NOVA SCOTIA INTO PRINCE EDWARD
ISLAND LANDFALL TIME COULD BE AS EARLY AS OVERNIGHT FRIDAY INTO
SATURDAY MORNING..TO SOMETIME SATURDAY AFTERNOON.


C. PUBLIC WEATHER

ASYMMETRIES IN THE WIND AND RAIN FIELDS WILL DEVELOP AS THE STORM
MOVES TOWARD THE MARITIMES. HEAVIEST RAIN WILL LIKELY MOVE TOWARD
THE FRONT AND LEFT SIDE OF THE STORM AND HIGHEST WINDS CONCENTRATED
TO THE RIGHT OF THE STORM TRACK.  THIS IS IMPORTANT TO KEEP IN MIND
WHEN CONSIDERING THE TRACK FORECAST RELATIVE TO YOUR LOCATION.
HIGHEST RAINFALLS WITH STORMS LIKE THIS WILL LIKELY BE TO THE LEFT
(WEST) OF THE STORM TRACK. LATER TODAY WE WILL INTRODUCE ESTIMATES OF
WIND SPEEDS AND RAINFALL IN A TRACK-RELATIVE SENSE..THEN ESTABLISH
GEOGRAPHICALLY-SPECIFIC DETAILS GOING INTO FRIDAY. REGARDING
RAINFALL POTENTIAL..FOR A STORM OF THIS NATURE..2500 DIVIDED BY
TWICE THE STORM SPEED IN KNOTS IS A RULE OF THUMB FOR RAINFALLS
ASSOCIATED WITH THE STORM CORE.  THAT ROUGHLY EQUATES TO 40 TO 70 MM
POTENTIAL.

Special weather summary message for Nova Scotia issued by Environment
Canada at 4:46 AM ADT Sunday 5 September 2010.

The following is a preliminary summary of hurricane Earl and its
Effects as it crossed the Maritimes on Saturday September 4 2010...

Hurricane Earl made landfall along the south shore of Nova Scotia at 
approximately 10:30 AM ADT in the vicinity of the Shelburne/Queens
County border.  The preliminary analysis by the Canadian Hurricane
Centre indicates that Earl made landfall as a category 1 hurricane 
with an intensity of 65 knots / 119 km/h.

Soon after landfall Earl was downgraded to a tropical storm but 
remained very intense as it tracked rapidly northeastward across
Lunenburg... Hants... And Colchester counties before moving into the 
Northumberland strait and across Eastern Queens County Prince Edward
Island Saturday afternoon.  Tropical storm Earl continued into the 
Gulf of St Lawrence passing just west of iles de la Madeleine late
In the afternoon.  Earl was declared post-tropical later Saturday 
night as it moved out of the Gulf of St Lawrence.

The following are some notable rainfall totals and peak wind gusts 
from hurricane Earl reported at various stations across Nova Scotia, 
New Brunswick and Prince Edward Island.

In addition to very strong winds and bands of heavy rain, hurricane 
Earl generated some very high waves offshore.  A buoy over west
Scotian Slope reported a peak wave height of 25.1 metres, and a
Buoy in the approaches to Halifax harbour reported a peak wave of 
23.3 metres.  Both these buoys reported sustained winds at or very 
near hurricane force.
