Thinking the NHC will pump up their hurricane prediction #'s a bit and classify Maria as a cane since she is close.

TROPICAL CYCLONE INFORMATION STATEMENT UPDATED BY THE CANADIAN
HURRICANE CENTRE OF ENVIRONMENT CANADA AT 3:02 PM ADT THURSDAY
15 SEPTEMBER 2011.
---------------------------------------------------------------------
TROPICAL CYCLONE INFORMATION STATEMENT FOR:
=NEW= LABRADOR
NEWFOUNDLAND
NOVA SCOTIA.
FOR TROPICAL STORM MARIA.
THE NEXT STATEMENT WILL BE ISSUED BY 9:00 PM ADT.
TROPICAL STORM MARIA MAY REACH HURRICANE STATUS THIS EVENING
THEN INTERACT WITH A NON-TROPICAL LOW AND TROUGH, BRINGING WIND
AND RAIN TO MUCH OF ATLANTIC CANADA FRIDAY AND SATURDAY.
---------------------------------------------------------------------
==DISCUSSION==
1. SUMMARY OF BASIC INFORMATION AT 3:00 PM ADT.
LOCATION: ABOUT 33.8 NORTH 66.2 WEST.
ABOUT 210 KILOMETRES NORTHWEST OF BERMUDA.
MAXIMUM SUSTAINED WINDS: 110 KM/HOUR.
PRESENT MOVEMENT: NORTH-NORTHEAST AT 55 KM/H.
MINIMUM CENTRAL PRESSURE: 989 MB.
2. PUBLIC WEATHER IMPACTS AND WARNINGS SUMMARY.
THE REMNANTS OF MARIA ARE EXPECTED TO MERGE/INTERACT WITH A
DEVELOPING TROUGH TO ITS NORTH THAT WILL CONNECT TO A MUCH LARGER
NON-TROPICAL LOW OVER LABRADOR.
OUR LATEST TRACK (ON THE http://WWW.HURRICANES.CA WEBSITE) IS ADJUSTED
NORTHWESTWARD AND SHOWS MARIA PASSING CLOSE TO THE AVALON PENINSULA
FRIDAY AFTERNOON. KEEP IN MIND THAT THERE WILL BE FAR-REACHING
IMPACTS OF THE COMBINED WEATHER SYSTEMS WELL AWAY FROM THE TRACK.
A. WIND.
WINDY CONDITIONS ARE TO BE EXPECTED THROUGHOUT ATLANTIC CANADA ON
FRIDAY AND SATURDAY AS THE NON-TROPICAL LOW AND TROUGH NORTH OF MARIA
UNITE. THE HIGHEST WINDS DIRECTLY FROM MARIA MAY PASS JUST OFFSHORE
- SOUTH OF NEWFOUNDLAND. BUT A SHIFT IN THE STORM TRACK ANY FARTHER
TO THE NORTHWEST WOULD INCREASE THE POSSIBILITY OF 100+ KM/H WIND
GUSTS ON THE AVALON PENINSULA.
A TROPICAL STORM WATCH IS BEING ISSUED FOR THE SOUTHERN AVALON FOR
THE POTENTIAL OF HIGH WINDS FROM MARIA.
THE AFOREMENTIONED COMBINED LOW IS BEING PREDICTED BY MANY COMPUTER
MODELS TO DELIVER HIGH WINDS OVER NEWFOUNDLAND AND LABRADOR ON
SATURDAY. STAY TUNED FOR SPECIFIC FORECASTS EARLY FRIDAY RELATED TO
THAT STORM.
B. RAINFALL.
RAINFALL WILL OCCUR OVER MANY PARTS OF ATLANTIC CANADA TONIGHT AND
FRIDAY FROM THE NON-TROPICAL LOW AND THE TROUGH DEVELOPING NORTH OF
MARIA. TROPICAL MOISTURE WILL FEED INTO THE TROUGH WHERE THE
POTENTIAL FOR THE HEAVIEST RAINFALL EXISTS. THIS REGION INCLUDES
EASTERN NEWFOUNDLAND WHERE 50 TO 80 MILLIMETRES IS EXPECTED.
LOCALLY HEAVY SHOWERS WITH LESSER TOTAL AMOUNTS WILL ALSO OCCUR OVER
THE EASTERN HALF OF NOVA SCOTIA BEGINNING LATER THIS EVENING.
NOTE THAT WHENEVER MOISTURE FROM A TROPICAL STORM FEEDS INTO A
FRONT/TROUGH IT IS LIKELY THAT RAINFALL RATES OF 15 TO 25 MILLIMETRES
PER HOUR WOULD OCCUR. SUCH RATES COULD LEAD TO FLASH-TYPE FLOODING
IN DITCHES AND SMALL RIVERS ESPECIALLY WHERE TERRAIN IS STEEP.
LOCAL FLOODING IN PRONE AREAS IS POSSIBLE. FORTUNATELY, RIVER WATER
LEVELS ARE AT OR BELOW NORMAL OVER EASTERN NEWFOUNDLAND. KEEP IN
MIND HOWEVER THAT SMALLER RIVERS/CREEKS WILL RESPOND MORE QUICKLY TO
HEAVY RAIN THAN LARGER ONES.
RAINFALL WARNINGS HAVE BEEN ISSUED FOR RAMEA CONNAIGRE EAST TO THE
AVALON PENINSULA THEN NORTH TO BONAVISTA AND TERRA NOVA PARK.
C. SURGE/WAVES.
MOST COASTAL REGIONS OF NEWFOUNDLAND CAN EXPECT WAVES TO BUILD ON
FRIDAY AS THE WEATHER SYSTEMS INTERACT. WAVE AND/OR SURGE EFFECTS
DIRECTLY FROM MARIA ARE POSSIBLE NOW OVER THE SOUTHERN AVALON
PENINSULA. IT WOULD ONLY TAKE A SMALL NORTHWARD SHIFT IN THE TRACK
TO ALLOW HIGHER WAVES AND SOME STORM SURGE TO AFFECT THE SOUTHERN
AVALON COASTLINES. STAY TUNED FOR UPDATES.
THE HIGHEST WAVES WILL BE SOUTH OF MARIA AND SHOULD REACH 4 TO 7
METRES LATE FRIDAY, MAINLY OVER THE GRAND BANKS.
SURGE AND WAVE ACTIVITY FROM THE MUCH LARGER COMBINED LOW COULD LEAD
TO SIGNIFICANT WAVE HEIGHTS WITH A POSSIBILITY OF STORM SURGE INTO
THE WEEKEND. THERE WILL BE A RISK FOR LARGE WAVES AND STORM SURGE
OVER WESTERN NEWFOUNDLAND AND THE LABRADOR COAST WITH A LESSER RISK
FOR THE NORTHEAST COAST OF NEWFOUNDLAND. THIS COMBINED STORM MAY END
UP REQUIRING A HOST OF ADDITIONAL WARNINGS COVERING LABRADOR, THE
GULF OF ST LAWRENCE REGION AND THE ISLAND (NL).
ONE FACTOR THAT MAY HELP EASE IMPACTS SOMEWHAT IS A RUN OF LOWER THAN
AVERAGE TIDES THIS WEEKEND.
3. MARINE WEATHER IMPACTS AND WARNINGS SUMMARY.
GALE TO STORM FORCE WINDS CAN BE EXPECTED AROUND ATLANTIC CANADA ON
FRIDAY AND SATURDAY FROM MARIA AND THE COMBINED STORM.

TROPICAL CYCLONE TECHNICAL INFORMATION STATEMENT ISSUED BY THE
CANADIAN HURRICANE CENTRE OF ENVIRONMENT CANADA AT 3.00 PM ADT
THURSDAY 15 SEPTEMBER 2011.
THE NEXT STATEMENT WILL BE ISSUED BY 9.00 PM ADT
1. CURRENT POSITION, STRENGTH, CENTRAL PRESSURE AND MOTION
AT 3.00 PM ADT , HURRICANE MARIA WAS LOCATED NEAR LATITUDE
33.8 N AND LONGITUDE 66.2 W , ABOUT 115 NAUTICAL MILES OR 210
KM NORTHWEST OF BERMUDA . MAXIMUM SUSTAINED WINDS ARE ESTIMATED
AT 60 KNOTS ( 110 KM/H ) AND CENTRAL PRESSURE AT 989 MB. MARIA
IS MOVING NORTH NORTHEAST AT 30 KNOTS ( 55 KM/H ).

3. TECHNICAL DISCUSSION
A. ANALYSIS
SATELLITE IMAGERY INDICATES THAT MARIA IS MOVING NORTH NORTHEAST AND
THE SURFACE PRESSURE CONTINUES TO FALL. ORGANISED CONVECTION PATTERN
WITH GOOD OUTFLOW IN ALL QUADRANT. CLOUD TOP TEMPERATURES HAVE
DROPPED TO -75 TO -80 C. AN EYE IS BECOMING APPARENT IN THE IMAGES
SINCE LATE MORNING. WEAK SHEAR EAST OF THE STORM AND STRONGER SHEAR
WEST OF IT HAVE NOT IMPEDED DEVELOPMENT. THE TRACK BRINGS MARIA
OVER SST VALUES OF 27-29C THROUGHOUT THE DAY AND THE STORM RELATIVE
SHEAR IS NOT EXPECTED TO CHANGE. THIS SUPPORTS THE FORECAST OF A
CATEGORY 1 SYSTEM DURING THE NEXT 18 HOURS.
B. PROGNOSTIC
NWP ARE IN GOOD AGREEMENT WITH RESPECT TO THE NORTH TO NORTHEAST
TRACK DURING THE NEXT 24-36 HOUR PERIOD. MOST MODELS CONTINUE TO
AGREE ON MARIA PASSING JUST TO THE SOUTHEAST OF THE AVALON
PENINSULA OF NEWFOUNDLAND. THE EARLY-CYCLE TRACK GUIDANCE FROM
12UTC SHOWS A MORE WESTERN TRACK PLACEMENT HENCE THE SMALL
ADJUSTMENT TO THE TRACK.
WHILE MOST INTENSITY GUIDANCE INDICATES HIGH-END TROPICAL STORM
STRENGTH WITH A FEW MODELS SUCH AS THE SHIPS SUGGEST STRENGTHENING
INTO A MARGINAL CAT-1 HURRICANE DURING THE NEXT FEW HOURS. THIS
COMBINED WITH THE EVIDENCE OF STRENGTHENING FROM RECENT SATELLITE
IMAGERY GIVES ENOUGH SUPPORT TO FORECAST IT DEVELOPING INTO A
MARGINAL HURRICANE UNTIL IT MOVES OVER CANADIAN WATERS. WHEN
MARIA MOVES OVER COOLER WATER NORTH OF THE GULF STREAM AND INTO THE
INCREASINGLY SHEARED ENVIRONMENT IT WILL TRANSITION INTO A
POST-TROPICAL STORM.
THE SPRAWLING WIND FIELD AROUND THE STORM AND ITS ASSOCIATED
PRECIPITATION MAY SPREAD WELL TO THE NORTHWEST OF THE TRACK.
ANOTHER COMPLICATING FACTOR IS THE MERGING OF THE TROPICAL
MOISTURE ENVELOPE WITH THE APPROACHING MID-LATITUDE COLD FRONT.
IN ANY EVENT MOST DETERMINISTIC MODELS ARE SUGGESTING A HEAVY
RAINFALL AND WIND EVENT FOR PARTS OF NEWFOUNDLAND AND LABRADOR.
THE GEM REG FOCUS THE HEAVY RAINFALL ALONG THE SOUTH COAST OF
NEWFOUNDLAND WITH A HINT THAT 100MM IS POSSIBLE.

SEVERE WEATHER BULLETIN
ISSUED BY THE CANADIAN HURRICANE CENTRE OF ENVIRONMENT CANADA
AT 3:12 PM ADT THURSDAY 15 SEPTEMBER 2011.
---------------------------------------------------------------------
TROPICAL STORM WATCH FOR:
=NEW= AVALON PENINSULA SOUTH.
TROPICAL STORM MARIA MAY REACH HURRICANE STATUS THIS EVENING
THEN INTERACT WITH A NON-TROPICAL LOW AND TROUGH WITH WIND AND
RAIN OVER SOUTHEASTERN NEWFOUNDLAND.
A TROPICAL STORM WATCH MEANS THAT A TROPICAL STORM OR AN
INCIPIENT TROPICAL STORM CONDITION POSES A POSSIBLE THREAT TO
THE SPECIFIED AREAS WITHIN 36 HOURS.
---------------------------------------------------------------------
==DISCUSSION==
THE REMNANTS OF MARIA ARE EXPECTED TO MERGE/INTERACT WITH A
DEVELOPING TROUGH TO ITS NORTH THAT WILL CONNECT TO A MUCH LARGER
NON-TROPICAL LOW OVER LABRADOR. MARIA SHOULD PASS CLOSE TO THE
AVALON PENINSULA FRIDAY AFTERNOON.
THERE WILL BE WINDY CONDITIONS THROUGHOUT ATLANTIC CANADA ON FRIDAY
AND SATURDAY AS THE NON-TROPICAL LOW AND TROUGH NORTH OF MARIA UNITE
OVER THE REGION. THE HIGHEST WINDS DIRECTLY FROM MARIA WILL LIKELY
PASS JUST OFFSHORE - SOUTH OF NEWFOUNDLAND. BUT A SHIFT IN THE STORM
TRACK ANY FARTHER TO THE NORTHWEST WOULD INCREASE THE POSSIBILITY OF

HEAVY RAIN IS EXPECTED ESPECIALLY OVER EASTERN NEWFOUNDLAND WHERE 50

SEVERE WEATHER BULLETIN
ISSUED BY THE CANADIAN HURRICANE CENTRE OF ENVIRONMENT CANADA
AT 3:12 PM ADT THURSDAY 15 SEPTEMBER 2011.
---------------------------------------------------------------------
TROPICAL STORM WATCH FOR:
=NEW= AVALON PENINSULA SOUTH.
TROPICAL STORM MARIA MAY REACH HURRICANE STATUS THIS EVENING
THEN INTERACT WITH A NON-TROPICAL LOW AND TROUGH WITH WIND AND
RAIN OVER SOUTHEASTERN NEWFOUNDLAND.
A TROPICAL STORM WATCH MEANS THAT A TROPICAL STORM OR AN
INCIPIENT TROPICAL STORM CONDITION POSES A POSSIBLE THREAT TO
THE SPECIFIED AREAS WITHIN 36 HOURS.
---------------------------------------------------------------------
==DISCUSSION==
THE REMNANTS OF MARIA ARE EXPECTED TO MERGE/INTERACT WITH A
DEVELOPING TROUGH TO ITS NORTH THAT WILL CONNECT TO A MUCH LARGER
NON-TROPICAL LOW OVER LABRADOR. MARIA SHOULD PASS CLOSE TO THE
AVALON PENINSULA FRIDAY AFTERNOON.
THERE WILL BE WINDY CONDITIONS THROUGHOUT ATLANTIC CANADA ON FRIDAY
AND SATURDAY AS THE NON-TROPICAL LOW AND TROUGH NORTH OF MARIA UNITE
OVER THE REGION. THE HIGHEST WINDS DIRECTLY FROM MARIA WILL LIKELY
PASS JUST OFFSHORE - SOUTH OF NEWFOUNDLAND. BUT A SHIFT IN THE STORM
TRACK ANY FARTHER TO THE NORTHWEST WOULD INCREASE THE POSSIBILITY OF
WIND GUSTS OF 100 KM/H OR MORE ON THE AVALON PENINSULA.
HEAVY RAIN IS EXPECTED ESPECIALLY OVER EASTERN NEWFOUNDLAND WHERE 50
TO 80 MILLIMETRES IS EXPECTED. LOCALLY HEAVIER RAINFALL COULD LEAD
TO LOCAL FLOODING IN PRONE AREAS IS POSSIBLE.
PLEASE REFER TO THE LATEST FORECASTS FOR FURTHER DETAILS.

TROPICAL CYCLONE TECHNICAL INFORMATION STATEMENT ISSUED BY THE
CANADIAN HURRICANE CENTRE OF ENVIRONMENT CANADA AT 3.30 PM ADT
THURSDAY 15 SEPTEMBER 2011.
THE NEXT STATEMENT WILL BE ISSUED BY 9.00 PM ADT
CORRECTED FIRST LINE OF PARAGRAPH NO.1. TROPICAL STORM INSTEAD
OF HURRICANE.
1. CURRENT POSITION, STRENGTH, CENTRAL PRESSURE AND MOTION
AT 3.00 PM ADT , TROPICAL STORM MARIA WAS LOCATED NEAR LATITUDE
33.8 N AND LONGITUDE 66.2 W , ABOUT 115 NAUTICAL MILES OR 210
KM NORTHWEST OF BERMUDA . MAXIMUM SUSTAINED WINDS ARE ESTIMATED
AT 60 KNOTS ( 110 KM/H ) AND CENTRAL PRESSURE AT 989 MB. MARIA
IS MOVING NORTH NORTHEAST AT 30 KNOTS ( 55 KM/H ).

SEP 17 3.00 AM 52.8N 48.4W 988 60 111 POST-TROPICAL
3. TECHNICAL DISCUSSION
A. ANALYSIS
SATELLITE IMAGERY INDICATES THAT MARIA IS MOVING NORTH NORTHEAST AND
THE SURFACE PRESSURE CONTINUES TO FALL. ORGANISED CONVECTION PATTERN
WITH GOOD OUTFLOW IN ALL QUADRANT. CLOUD TOP TEMPERATURES HAVE
DROPPED TO -75 TO -80 C. AN EYE IS BECOMING APPARENT IN THE IMAGES
SINCE LATE MORNING. WEAK SHEAR EAST OF THE STORM AND STRONGER SHEAR
WEST OF IT HAVE NOT IMPEDED DEVELOPMENT. THE TRACK BRINGS MARIA
OVER SST VALUES OF 27-29C THROUGHOUT THE DAY AND THE STORM RELATIVE
SHEAR IS NOT EXPECTED TO CHANGE. THIS SUPPORTS THE FORECAST OF A
CATEGORY 1 SYSTEM DURING THE NEXT 18 HOURS.
B. PROGNOSTIC
NWP ARE IN GOOD AGREEMENT WITH RESPECT TO THE NORTH TO NORTHEAST
TRACK DURING THE NEXT 24-36 HOUR PERIOD. MOST MODELS CONTINUE TO
AGREE ON MARIA PASSING JUST TO THE SOUTHEAST OF THE AVALON
PENINSULA OF NEWFOUNDLAND. THE EARLY-CYCLE TRACK GUIDANCE FROM
12UTC SHOWS A MORE WESTERN TRACK PLACEMENT HENCE THE SMALL
ADJUSTMENT TO THE TRACK.
WHILE MOST INTENSITY GUIDANCE INDICATES HIGH-END TROPICAL STORM
STRENGTH WITH A FEW MODELS SUCH AS THE SHIPS SUGGEST STRENGTHENING
INTO A MARGINAL CAT-1 HURRICANE DURING THE NEXT FEW HOURS. THIS
COMBINED WITH THE EVIDENCE OF STRENGTHENING FROM RECENT SATELLITE
IMAGERY GIVES ENOUGH SUPPORT TO FORECAST IT DEVELOPING INTO A
MARGINAL HURRICANE UNTIL IT MOVES OVER CANADIAN WATERS. WHEN
MARIA MOVES OVER COOLER WATER NORTH OF THE GULF STREAM AND INTO THE
INCREASINGLY SHEARED ENVIRONMENT IT WILL TRANSITION INTO A
POST-TROPICAL STORM.
THE SPRAWLING WIND FIELD AROUND THE STORM AND ITS ASSOCIATED
PRECIPITATION MAY SPREAD WELL TO THE NORTHWEST OF THE TRACK.
ANOTHER COMPLICATING FACTOR IS THE MERGING OF THE TROPICAL
MOISTURE ENVELOPE WITH THE APPROACHING MID-LATITUDE COLD FRONT.
IN ANY EVENT MOST DETERMINISTIC MODELS ARE SUGGESTING A HEAVY
RAINFALL AND WIND EVENT FOR PARTS OF NEWFOUNDLAND AND LABRADOR.
THE GEM REG FOCUS THE HEAVY RAINFALL ALONG THE SOUTH COAST OF
NEWFOUNDLAND WITH A HINT THAT 100MM IS POSSIBLE.

Re: ATL: MARIA - Tropical Storm - Discussion
Although stranger things have happened, it looks like Maria will be the first storm to become a hurricane that fails to become a major.

Re: ATL: MARIA - Tropical Storm - Discussion
Not asleep here
Looks like Maria finally got its act together. Hopefully Bermuda doesn't receive damaging weather. A bit OT, I've been kinda watching the USGS site 'cuz it's been a busy day for earthquakes....6.2 in Japan, 7.2 in Fiji, 5.0 in Cuba etc. Fascinating to see the ring of fire waking up.

NWS NATIONAL HURRICANE CENTER MIAMI FL AL142011
500 PM AST THU SEP 15 2011
SATELLITE AND RADAR IMAGES INDICATE THAT MARIA HAS BECOME A
HURRICANE. THE CLOUD PATTERN HAS BECOME MORE SYMMETRIC AND A
CENTRAL DENSE OVERCAST HAS FORMED. AN EYE HAS BEEN EVIDENT ON
BERMUDA RADAR FOR THE PAST FEW HOURS...AND IT HAS OCCASIONALLY BEEN
SEEN IN THE VISIBLE IMAGERY. THE INITIAL INTENSITY IS RAISED TO
65 KT...IN AGREEMENT WITH THE DVORAK ESTIMATE FROM TAFB.
MARIA CONTINUES TO ACCELERATE TO THE NORTH-NORTHEAST...NOW MOVING
ABOUT 31 KT. THE HURRICANE IS EXPECTED TO TURN TO THE NORTHEAST
AND MOVE 45 KT OR FASTER ON FRIDAY AS IT GET CAUGHT IN VERY STRONG
SOUTHWESTERLY FLOW AHEAD OF A LARGE TROUGH OVER THE NORTHEASTERN
UNITED STATES. THE GLOBAL MODEL GUIDANCE CONTINUES TO SHIFT TO THE
NORTHWEST CLOSE TO NEWFOUNDLAND...AND THE OFFICIAL FORECAST WILL BE
MOVED IN THAT DIRECTION...THOUGH IT IS STILL ON THE SOUTHEASTERN
SIDE OF THE GUIDANCE.
FURTHER STRENGTHENING IS LIKELY OVERNIGHT WHILE THE SHEAR REMAINS
MODERATE AND THE WATER IS WARM. WEAKENING SHOULD BEGIN TOMORROW
DUE TO RAPIDLY INCREASINGLY SOUTHWESTERLY SHEAR AND MUCH COOLER
WATERS. HOWEVER...MARIA IS EXPECTED TO BE NEAR HURRICANE STRENGTH
AS IT NEARS NEWFOUNDLAND TOMORROW...DUE IN PART TO THE EXPECTED VERY
FAST FORWARD MOTION. THE NHC FORECAST IS RAISED FROM THE PREVIOUS
ONE...AND LIES CLOSE TO THE SHIPS/LGEM MODELS.
THE LEFTWARD SHIFT IN THE FORECAST AND INCREASE IN INTENSITY
NECESSITATE THE ISSUANCE OF A HURRICANE WATCH AND TROPICAL STORM
WARNING FOR SOUTHEASTERN NEWFOUNDLAND. IF THERE IS A FURTHER
WESTWARD SHIFT IN THE GUIDANCE OR MARIA BECOMES STRONGER...A

Don't see that everyday.
It's not as uncommon as many think. Newfoundland is in a prime area to catch recurves.

Re: ATL: MARIA - Hurricane - Discussion
What's the record for the furthest north that a storm first attained hurricane strength? Maria didn't get there until 35N, don't think I've seen that since I've been paying attention to storms.
