3. PUBLIC WEATHER IMPACTS AND WARNINGS SUMMARY
RAINFALL WARNINGS ARE IN EFFECT FOR WESTERN NOVA SCOTIA. IT IS
LOOKING LESS LIKELY NOW THAT WIND WARNINGS WILL BE REQUIRED FOR
NOVA SCOTIA. ROUGH SURF SHOULD STILL BE EXPECTED ALONG THE ATLANTIC
FACING COAST OF SOUTHWESTERN NOVA SCOTIA LATE FRIDAY AS BERYL PASSES.

4. MARINE WEATHER IMPACTS AND WARNINGS SUMMARY
GALE WARNINGS ARE MAINTAINED IN SOUTHWESTERN MARITIME WATERS AND
ARE CARRIED FORWARD IN THE EXTENDED MARINE FORECASTS THROUGH CENTRAL
MARITIME AND NEWFOUNDLAND WATERS AROUND THE AVALON PENINSULA.

5. TECHNICAL DISCUSSION

A. ANALYSIS
SATELLITE IMAGERY INDICATED THAT BERYL WEAKENED THURSDAY AFTERNOON
AND DEVOLVED TO A SWIRL OF LOW CLOUDS AROUND A TIGHT CENTRE. THIS
COUPLED WITH LATE AFTERNOON US RECON SUGGESTS THAT THE CENTRAL
PRESSURE REMAINS ABOVE 1000 MB AND THAT MAXIMUM SUSTAINED WINDS HAVE
DROPPED BELOW 50 KTS. VISUAL SATELLITE LOOPS ALSO SUGGESTED THAT
BERYL BEGAN HEADING MORE TOWARD THE ENE BETWEEN 19 AND 20Z. WE STILL
EXPECT BERYL TO TRACK OVER COOLER WATER TONIGHT WHICH WILL FAVOUR
WEAKENING.

B. PROGNOSTIC
WE ARE IN
COMPLETE ACCORD WITH NHC WITH REGARD TO THE STORM SPEED AND MAX WINDS
BUT DIFFER ONLY OVER THE TRACK DIRECTION OVER NOVA SCOTIA. WE ARE
RELUCTANT TO TAKE IT INLAND AND THIS IS BASED ON TWO FACTORS.
FIRSTLY..THE INITIAL MOTION APPEARS MORE ENE THAN NE. SECONDLY..OUR
EXPERIENCE WITH THESE TYPES OF STORMS TELLS US THAT THEY TEND TO
TRACK TO THE RIGHT OF NUMERICAL MODEL TRACKS..WHICH INDICATE THE
CENTER TRACKING FARTHER NORTH. ACCORDINGLY..WE FAVOUR BERYL PASSING
JUST SOUTH OF NOVA SCOTIA'S ATLANTIC COASTLINE.

CANADIAN MODELS CONTINUE STRUGGLING WITH HANDLING THIS SYSTEM AND
THE PARALLEL GLOBAL DOES NOT HAVE A MARKEDLY IMPROVED SOLUTION OVER
THE OPERATIONAL RUN..AN ASSESSMENT BASED ON ITS INITIAL HANDLING
OF THE STORM. ALL MODELS EXCEPT THE 18Z RUN OF THE UKMET TAKE THE
STORM FARTHER NORTH..MANY THROUGH THE BAY OF FUNDY. AS A RESULT
THEY MERGE WITH THE APPROACHING FRONT. WE ARE HARD-PRESSED TO SEE WHY
THE STORM WOULD TURN MORE NORTHWARD AT THIS POINT..SOMETHING REQUIRED
FOR THOSE SOLUTIONS TO WORK..SO WE ARE STICKING WITH OUR PREVIOUS
THINKING. REGARDING THE 18Z UKMET RUN..IT NOW HAS A MORE IDENTIFIABLE
FEATURE THAN THE 12Z RUN AND ITS VERSION OF BERYL REMAINS INTACT
THROUGH MARITIME WATERS AND HAS SIMILAR POSITION FOR 22/00Z AS OUR
CURRENT FORECAST..THAT IS..JUST SOUTH OF HALIFAX.

NO CHANGE IN PREVIOUS THINKING REGARD EXTRATROPICAL TRANSITION..WE
CONTINUE SEEING TRANSITION BEING COMPLETED BY THE TIME IT NEARS NOVA
SCOTIA WITH WEAKENING OF THE WARM CORE. WE ARE NOT EXPECTING ANY
INTERACTION WITH THE APPROACHING FRONTAL SYSTEM SINCE BERYL SHOULD BE
SUFFICIENTLY SHEARED-OUT AHEAD BY THE TIME THE FRONT REACHES THE
MARITIMES.

C. PUBLIC WEATHER
WE HAVE NO REASON TO CHANGE THE CURRENT FORECAST WITH REGARD TO THE
RAIN WARNINGS AND WIND SPEEDS. DETAILED FORECASTS ARE FOUND UNDER
FORECAST HEADERS FPCN11/14/15 CWHX FOR THE MARITIME PROVINCES. MORE
DETAILS FOR NEWFOUNDLAND'S SATURDAY FORECAST WILL BE ISSUED EARLY
FRIDAY MORNING.

D. MARINE WEATHER
IN LIGHT OF THE WEAKER WINDS WITH THE STORM..THE CHC WAVE MODEL
NOW GENERATES ONLY MAX SIG WAVES OF NEART 6 METRES.

3. PUBLIC WEATHER IMPACTS AND WARNINGS SUMMARY THE ATLANTIC STORM
PREDICTION CENTRE WILL BE ISSUING RAINFALL WARNINGS FOR WESTERN NOVA
SCOTIA. GUSTS OF 80 KM/H MAY BRUSH ALONG THE ATLANTIC COAST OF NOVA
SCOTIA LATE FRIDAY. WIND WARNINGS MAY BE REQUIRED BUT HAVE NOT BEEN
ISSUED AT THIS TIME. SIGNIFICANT COASTAL WAVES SHOULD BE EXPECTED
ALONG THE ATLANTIC FACING COAST OF SOUTHWESTERN NOVA SCOTIA LATE
FRIDAY AS BERYL
PASSES.

4. MARINE WEATHER IMPACTS AND WARNINGS SUMMARY
GALE WARNINGS ARE MAINTAINED IN SOUTHWESTERN MARITIME WATERS AND
ARE CARRIED FORWARD IN THE EXTENDED MARINE FORECASTS THROUGH CENTRAL
MARITIME AND NEWFOUNDLAND WATERS AROUND THE AVALON PENINSULA.

5. TECHNICAL DISCUSSION

A. ANALYSIS
A CLEAR AREA WITHIN THE STORM CENTRE... DARE WE CALL IT AN EYE...
DEVELOPED LATE THIS MORNING AT THE SAME TIME THAT CONVECTIVE TOPS
WARMED RAPIDLY. NHC INVESTIGATIONS CONTINUE MAINTAINING THIS AS A
50-KNOT WIND SYSTEM AND SURFACE OBS ARE IN ACCORD. LOW CLOUD
FILLED INTO THE "EYE" GIVING A CLEAR INDICATION OF THE LLCC ON VIS
IMAGERY. BERYL APPEARS TO BE WOBBLING SLIGHTLY TO THE NORTHWEST
WHICH MAY HAVE AN IMPACT ON OUR TRACK TIMING.

B. PROGNOSTIC
FROM DISCUSSION WITH NHC WE ARE IN AGREEMENT THAT BERYL SHOULD HAVE
COMPLETED ET DURING THE DAY TOMORROW... HENCE THE LAST NHC POSITION
IS FOR FRIDAY EVENING AT 00Z. WE CONTINUE THROUGH THE RESPONSE ZONE
AS A POST TROPICAL SYSTEM.

THERE IS INSUFFICIENT NEW INFORMATION AT THIS TIME TO WARRANT A
SIGNIFICANT CHANGE. THE FINAL NHC POSITION IS SLIGHTLY SLOWER THAN
OUR TRACK HOWEVER WE HAVE MAINTAINED OUR PREVIOUS TRACK SPEED SINCE
THE NEW GEM SHORTWAVE IS ACTUALLY FASTER AND WE BELIEVE THAT THE
POST TROPICAL SYSTEM WILL BE MORE BAROCLINIC AT THAT POINT AND LIKELY
MOVING WITH THE SHORT WAVE. ALL INDICATIONS ARE THAT BERYL WILL BE
SHEARED AWAY AND UNDERGOING ACCELERATION BEFORE GETTING ENTANGLED
WITH THE APPROACHING FRONT SO WE ARE NOT EXPECTING A REDEVELOPER AT
THIS TIME. OUR FORECAST TRACK FALLS IN THE MIDDLE OF THE ENVELOPE
DEFINED BY THE 12Z UKMET AND GFDL RUNS. THE 12Z CYCLONE PHASE RUNS
ARE NOT AVAILABLE PRIOR TO ISSUE TIME SO WE ARE CONTINUING WITH
THINKING
OF PREVIOUS MESSAGE REGARDING ET.

THIS TRACK TAKES BERYL OVER A TONGUE OF MUCH COOLER WATER BEGINNING
OVERNIGHT AND COUPLED WITH THE GREATER SHEAR AT THAT TIME IT SHOULD
START WEAKENING. IF ANYTHING OUR MAX WIND STRENGTH MAY BE ON THE
HIGH SIDE.

THE APPARENT STORM WOBBLED MAY HAVE AN IMPACT ON OUR TRACK SPEED
HOWEVER WE HAVE NOT FACTORED THIS INTO THINGS AT THIS TIME.

C. PUBLIC WEATHER
BECAUSE OF THE UNCERTAINTY OF BERYLS PROXIMITY TO THE COAST AND HOW
MUCH WEAKENING WILL OCCUR AS IT MOVES OVER THE COOLER WATERS WE ARE
RELUCTANT TO ISSUE A TROPICAL STORM WARNING AT THIS TIME... HOWEVER
THE ATLANTIC STORM PREDICTION CENTRE WILL LIKELY FORECAST GUSTS OF
80 KM/H ALONG THE ATLANTIC COAST OF NOVA SCOTIA... ESPECIALLY IN
WESTERN REGIONS.

RAINFALL AMOUNTS ARE VERY TRICKY WITH THIS SYSTEM AS IT UNDERGOES
ET BUT LOCAL AMOUNTS OF 100 MM ARE NOT UNREASONABLE WITH A STORM OF
THIS NATURE.

D. MARINE WEATHER
THE CHC TRAPPED FETCH MODEL GENERATES 8M WAVES LATE FRIDAY BECAUSE
THE STORM TRACK IS ON A STRAIGHT LINE AND INCREASING UNIFORMLY IN
SPEED... SO RESONANCE IS A GOOD BET. WHETHER THEY REACH 8 METRES IS
HARD TO SAY... BUT GIVEN THE TRACK AND WIND STRENGTH 6-7 METRES IS
A GOOD BET. THESE WAVES WILL BE ON A DIRECT LINE TOWARDS THE CAPE
SABLE AREA OF NOVA SCOTIA BUT WILL NOT LIKELY ARRIVE UNTIL THE STORM
ITSELF ARRIVES.

4. MARINE WEATHER IMPACTS AND WARNINGS SUMMARY
GALE WARNINGS HAVE BEEN POSTED IN SOUTHWESTERN MARITIME WATERS AND
GALES ARE CARRIED FORWARD IN THE EXTENDED MARINE FORECASTS BASED ON
OUR FORECAST TRACK OF BERYL.

5. TECHNICAL DISCUSSION

A. ANALYSIS
?HERE WAS A WESTWARD ADJUSTMENT OF THE STORM CENTRE BASED ON AIR
RECON AT 06Z. IR SATELLITE IMAGERY SUGGESTS THAT THE STORM CENTRE
IS CURRENTLY LOCATED NEAR THE NORTHERN EDGE OF THE HEAVIEST
CONVECTION. 12Z POSITION BASED ON NHC UPDATED MESSAGE INDICATING IT
IS A RECON FIX.

B. PROGNOSTIC
TRACK FOLLOWS NHC GUIDANCE. ?HE 06Z ADJUSTMENT RESULTED IN A WESTWARD
ADJUSTMENT IN OUR FORECAST TRACK. WE GENERALLY FOLLOW NHC GUIDANCE
OVER NEXT 36 TO 48 HOURS. AS A RESULT BERYL NOW CROSSES THE
COASTLINE OF NOVA SCOTIA.

BERYL WILL SHOW SLIGHT STRENGHTENING OVER NEXT 24 HOURS
AS IT MOVES OVER WARM WATER. ONCE BERYL PASSES NORTH OF 41N IT
MOVES INTO COLDER WATER AND SHOULD GRADUALLY WEAKEN.
AT 00Z UPPER ANALYSIS SHOWED A VORT TROUGH OVER LAKE MICHIGAN
WHICH WEAKENS AS IT MOVES TO LIE ABOUT 6 DEG NORTHWEST OF BERYL
BY 12Z FRIDAY. AT THIS TIME BERYL COMES UNDER INCREASING WESTERLY
UPPER FLOW AND BEGINS ITS EXTRATROPICAL TRANSITION.

A COLD FRONT APPROACHES FROM THE WEST TO LIE OVER NE NEW BRUNSWICK
BY 00Z SATURDAY. MOISTURE FROM BERYL IS EXPECTED TO FEED INTO THIS
FRONTAL SYSTEM THUS LEADING TO HEAVIER PCPN OVER NB.
THE GFS AND CDN GBL MODELS GRAB BERYL AND PLACE IT ON FRONT AT 48HR.
GEM MAKES A GOOD JOB OF KEEPING BERYL OFF SOUTH SHORE OF NS ALBEIT A
BIT CLOSE TO THE COAST. USED 500 MB VORT MAX ASSOCIATED WITH
BERYL WHICH GFS AND GLOBAL PRESERVED DESPITE THEIR SURFACE
INTERACTION WITH FRONT. FOLLOWED THIS VORT TROUGH AND
CORRESPONDING UPPER FLOW TO KEEP BERYL SOUTH OF THE BURIN
PENINSULA SATURDAY MORNING. THEREFORE HAVE FORECAST A TRACK
SOMEWHAT SOUTH AND MUCH FASTER UNDER WESTERLY FLOW ALOFT
COMPARED TO PREVIOUS FORECAST. GFS LOSES VORT IDENTITY
ONCE BERYL PASSES THROUGH CAPE RACE SO UTILISED CDN GLB
THROUGH REMAINING CANADIAN WATERS. THEREAFTER THE REMNANTS OF
BERYL SLIDES TOWARD GREENLAND UP THE REAR FLANK OF AN UPPER RIDGE.
THIS AGREES WITH NOGAPS EXCEPT THAT IT PUSHES BERYL THROUGH UPPER
RIDGE.

THE 0533Z RUN OF THE GFDL TAKES BERYL ON A MORE WESTWARD TRACK
THROUGH THE FORECAST PERIOD BUT IT REMAINS AS AN OUTLIER... HOWEVER
THE CURRENT MOTION WOULD LEAN ONE TO THINK IT LOOKS MORE APPROPRIATE
IN THE IMMEDIATE FUTURE. WE ARE WATCHING THIS.

FSU CYCLONE PHASE SPACE FOR NOGAPS AND GFS SHOW RAPID TRANSITION
ON THE 21ST... SUCH THAT TRANSITION MAY BE COMPLETED BY THE TIME
IT REACHES WESTERN MARITIME WATERS. INTERESTINGLY THESE MODELS
MOVE IT ALMOST DIRECTLY FROM SYMMETRIC WARM CORE TO ASYMMETRIC
COLD CORE . . . BUT THE TRANSITION IS RATHER QUICK. OTHER MODELS
KEEP IT LOOKING MOSTLY TROPICAL HOWEVER IT IS HARD TO NOT EXPECT
TRANSITION CONSIDERING THE STRENGTH OF THE UPPER FLOW THAT WILL BE
DRIVING IT THROUGH CANADIAN WATERS.

OF COURSE THERE IS UNCERTAINTY IN ALL OF THIS. TO WHAT DEGREE
WILL THE FRONT INTERACT WITH BERYL IS A TROUBLING QUESTION..
ESPECIALLY NOW THAT BERYL WAS REPORTED FARTHER WEST THAN EXPECTED
AT 06Z. TO THIS POINT WE ARE FAVOURING BERYL AS AN ENTITY THAT IS
SEPARATE FROM THE FRONT.

C. PUBLIC WEATHER
A TRACK THAT IS FARTHER WEST WILL REQUIRE A RE-THINK ON OUR RAIN
AMOUNTS. BERYL IS CAUGHT IN THE WESTERLIES AS IT PASSES THROUGH
NS.. HOWEVER SINCE ITS INTERACTION WITH THE FRONT IS STILL
UNCERTAIN THIS MAY REQUIRE A RETHINK OF OUR P.E.I. AMOUNTS
ESPECIALLY OVER NOVA SCOTIA. WIND MAY BE MORE OF AN ISSUE AS ASPC
FORECASTS HAVE GUSTS TO 70 KM/H OVER SOUTH SHORE LATE FRIDAY WHICH
MATCHES THEIR CURRENT MARINE WARNINGS.

D. MARINE WEATHER
A FARTHER WESTWARD TRACK MAY REQUIRE AN ADJUSTMENT OF ASPC MARINE
FORECASTS ESPECIALLY WITH RESPECT TO DIRECTION.
