TROPICAL STORM HARVEY ADVISORY NUMBER 10
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
5 PM AST THU AUG 04 2005
...HARVEY EXPECTED TO LINGER FOR A FEW DAYS AS IT MOVES OVER THE
OPEN WATERS OF THE NORTH ATLANTIC...
AT 5 PM AST...2100Z...THE CENTER OF TROPICAL STORM HARVEY WAS
LOCATED NEAR LATITUDE 32.4 NORTH...LONGITUDE 61.8 WEST OR ABOUT
175 MILES... 280 KM...EAST OF BERMUDA.
HARVEY IS MOVING TOWARD THE EAST-NORTHEAST NEAR 12 MPH...19 KM/HR. A
GRADUAL DECREASE IN FORWARD SPEED IS EXPECTED DURING THE NEXT 24
HOURS.
MAXIMUM SUSTAINED WINDS REMAIN NEAR 65 MPH...100 KM/HR...WITH
HIGHER GUSTS.
NO SIGNIFICANT CHANGE IN STRENGTH IS FORECAST DURING THE NEXT 24
HOURS. HOWEVER...A SMALL INCREASE IN INTENSITY WOULD BRING HARVEY
TO HURRICANE STATUS.
TROPICAL STORM FORCE WINDS EXTEND OUTWARD UP TO 115 MILES
...185 KM FROM THE CENTER.
ESTIMATED MINIMUM CENTRAL PRESSURE IS 994 MB...29.35 INCHES.
REPEATING THE 5 PM AST POSITION...32.4 N... 61.8 W. MOVEMENT
TOWARD...EAST-NORTHEAST NEAR 12 MPH. MAXIMUM SUSTAINED

TROPICAL STORM HARVEY DISCUSSION NUMBER 10
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
5 PM EDT THU AUG 04 2005
HARVEY CONTINUES TO HAVE A WELL-ORGANIZED CLOUD PATTERN WITH MARKED
CONVECTIVE CURVED BANDS AND GOOD OUTFLOW. T-NUMBERS SUPPORT AN
INITIAL INTENSITY OF 55 KNOTS. THE SHEAR MAY RELAX SOME...AND HARVEY
COULD EXPERIENCE A MODEST STRENGTHENING IN THE NEXT DAY OR SO
BEFORE IT BEGINS TO MOVE OVER COOLER WATERS.
HARVEY IS EMBEDDED WITHIN THE WESTERLIES AND IS MOVING TOWARD THE
EAST-NORTHEAST ABOUT 10 KNOTS. THE CYCLONE IS EXPECTED TO CONTINUE
ON THIS GENERAL TRACK...BUT WITH A DECREASE IN FORWARD SPEED...SINCE
THE STEERING CURRENTS ARE FORECAST TO BECOME VERY LIGHT.
BEYOND 3 DAYS...A NEW SHORTWAVE WILL ACCELERATE THE WESTERLY FLOW
RESULTING IN AN INCREASE IN HARVEY'S FORWARD SPEED. BOTH THE
SHORT TERM DECREASE IN SPEED AND THE LATER ACCELERATION ARE
SUGGESTED BY MOST OF THE GUIDANCE.

TROPICAL STORM HARVEY DISCUSSION NUMBER 12
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
5 AM EDT FRI AUG 05 2005
CONVENTIONAL AND MICROWAVE SATELLITE IMAGERY INDICATE HARVEY IS
EXPERIENCING SIGNIFICANT WEST-SOUTHWESTERLY UPPER-LEVEL SHEAR...
WHICH HAS CAUSED THE LOW-LEVEL CIRCULATION TO LAG BEHIND TO THE
SOUTHWEST OF THE MID- AND UPPER-LEVEL CIRCULATIONS. THE OVERALL
CONVECTIVE PATTERN HAS ALSO BECOME LESS DISTINCT...ALTHOUGH A BURST
OF DEEP CONVECTION HAS REDEVELOPED OVER AND JUST NORTHEAST OF THE
SURFACE CENTER DURING THE PAST COUPLE OF HOURS. THE INTENSITY IS
BEING MAINTAINED AT 55 KT BASED ON DVORAK T-NUMBERS OF T3.5/55 KT
FROM BOTH TAFB AND SAB...AND A COUPLE OF 55 KT UNFLAGGED WIND
VECTORS NOTED IN A 04/2228Z QUIKSCAT OVERPASS.
THE INITIAL MOTION ESTIMATE IS 070/08. THE INITIAL POSITION WAS
ADJUSTED ABOUT 30 NMI SOUTH OF THE PREVIOUS POSITIONS AND FORECAST
TRACK. OTHER THAN THAT...THE FORECAST TRACK AND REASONING REMAINS
UNCHANGED FROM THE PAST FEW ADVISORIES. A SHORTWAVE TROUGH TO THE
NORTH OF HARVEY THAT HAD BEEN MOVING THE CYCLONE ALONG AT A DECENT
CLIP HAS NOW LIFTED OUT TO THE NORTHEAST AS NOTED IN WATER VAPOR
IMAGERY. THIS HAS RESULTED IN A WEAKENING OF THE STEERING FLOW.
HOWEVER...ANOTHER UPSTREAM SHORTWAVE CURRENTLY MOVING OVER
SOUTHEASTERN CANADA IS EXPECTED TO DIG SOUTHWARD AND SLOWLY LIFT
HARVEY NORTHEASTWARD BY 36 HOURS...WITH GRADUAL ACCELERATION OVER
COOLER WATER EXPECTED AFTER THAT. THE OFFICIAL FORECAST TRACK IS
SIMILAR TO THE PREVIOUS ADVISORY...AND IS A LITTLE SLOWER AND TO
THE RIGHT OF THE NHC MODEL CONSENSUS.
THE VERTICAL SHEAR IS FORECAST TO WEAKEN TO LESS THAN 10 KT BY 24
HOURS...SO LITTLE CHANGE IN INTENSITY IS EXPECTED BEFORE THEN.
AFTERWARDS...HOWEVER...THE VERTICAL SHEAR WILL GRADUALLY INCREASE
TO 30 KT OR MORE BY 96 HOURS AS HARVEY ALSO MOVES OVER SUB-26C
SSTS. THIS SHOULD BRING ABOUT STEADY WEAKENING AND POSSIBLE
TRANSITION TO AN EXTRATROPICAL LOW BY 96 HOURS.

HARVEY CONTINUES AS A TIGHT SWIRL OF LOW CLOUDS WITH MOST OF THE
DEEP CONVECTION TO THE NORTH AND EAST OF THE CENTER. IT APPEARS ON
SATELLITE THAT HARVEY IS LOCATED AT THE TAIL OF A FRONTAL ZONE.
HARVEY SHOULD GRADUALLY WEAKEN DUE TO SHEAR IN THE NEXT DAY OR TWO.
THEREAFTER...MOST OF THE MODELS SHOW INTENSIFICATION AND AN
EXPANSION OF THE CIRCULATION AS A NEW MID-LEVEL SHORT WAVE
APPROACHES. THEREFORE...HARVEY WILL LIKELY BECOME A STRONG
EXTRATROPICAL CYCLONE OVER THE COLD WATERS OF THE NORTH ATLANTIC
DURING THIS PERIOD.
HARVEY HAS BEEN DRIFTING EASTWARD ABOUT 4 TO 6 KNOTS DURING THE DAY.
THIS GENERAL MOTION WILL LIKELY CONTINUE TONIGHT...BUT WITH A LITTLE
RIDGING DEVELOPING TO THE EAST...THE CYCLONE SHOULD TURN MORE TO
THE NORTHEAST DURING THE NEXT DAY OR SO. THEREAFTER...HARVEY SHOULD

Yes P.K watch it there as it can grow into a big extratropical storm for your area.

TROPICAL STORM HARVEY DISCUSSION NUMBER 16
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
5 AM EDT SAT AUG 06 2005
A DEEP BURST OF CONVECTION HAS DEVELOPED OVER AND NORTHEAST OF THE
PREVIOUSLY EXPOSED LOW-LEVEL CIRCULATION. THEREFORE...THE INITIAL
INTENSITY IS BEING MAINTAINED AT 45 KT...WHICH SUPPORTED BY AN
EARLIER QUIKSCAT OVERPASS THAT CONTAINED 40-KT AND 50-KT UNFLAGGED
WIND VECTORS JUST NORTHEAST OF THE CENTER.
THE INITIAL MOTION ESTIMATE IS 030/06. HARVEY HAS TURNED TO THE
NORTH-NORTHEAST SOONER THAN PREVIOUSLY EXPECTED...BUT THE OVERALL
FORECAST TRACK AND REASONING REMAINS UNCHANGED FROM THE PREVIOUS
ADVISORY. AS A RESULT...THE OFFICIAL FORECAST IS TO THE LEFT OF THE
PREVIOUS FORECAST...BUT IS STILL TO THE RIGHT OF THE MODEL
CONSENSUS.
HARVEY IS EXPECTED TO GRADUALLY MOVE OVER COOLER WATER AND GRADUALLY
COME UNDER INCREASING WESTERLY SHEAR AS THE NEXT SHORTWAVE TROUGH
MOVES IN FROM THE WEST AND LIFTS OUT THE CYCLONE TO THE NORTHEAST.
THIS SHOULD BRING ABOUT GRADUAL WEAKENING UNTIL THE CYCLONE GETS
CAPTURED BY THE SYSTEM AND DEEPENS SLIGHTLY INTO AN EXTRATROPICAL
LOW PRESSURE SYSTEM BY 72 HOURS.

It appears that Harvey is becoming MUCH better organized again and it won't be surprising to see the winds bumped up on the next advisory to 60 mph. The storm has defied the forecasts of increasing shear and convection is deepening in a very organized manner over it. As it moves NE, it will move in tandem with the winds and it is very possible that it could approach hurricane strength after all this time. I'll be watching...

It could strengthen, but it isn't very likely since it is currently over 27C water and falling fast.

I think Harvey's window for strengthening has closed. Harvey looks better now, but I think it's just trying to ward off extratropical transition right now. There still isn't much convection to the SW of the center, and it wouldn't take much more shear to expose the center again.
EDIT: 12z model runs:
Models are shifting south. For some reason the BAMM starts Harvey in a big loop in the central Atlantic.

TROPICAL STORM HARVEY DISCUSSION NUMBER 18

5 PM EDT SAT AUG 06 2005
HARVEY'S CIRCULATION TOOK A SHARP LEFT HOOK LATE THIS MORNING...AND
THE LOW-LEVEL CENTER NEVER FULLY CONNECTED WITH THE EARLIER
CONVECTIVE BURST. THE SYSTEM ONCE AGAIN HAS A SHEARED
APPEARANCE...WITH THE CONVECTION TO THE NORTH AND NORTHEAST OF THE
CENTER. DVORAK CLASSIFICATIONS ARE UNCHANGED COMPARED TO 6 HOURS
AGO AND SO I WILL LEAVE THE INITIAL INTENSITY AT 50 KT. ADDITIONAL
INTENSIFICATION NOW APPEARS LESS LIKELY BEFORE COOLER WATERS ARE
ENCOUNTERED WITHIN 24 HOURS. HOWEVER...HARVEY IS LIKELY TO FIND
NEW LIFE AS AN EXTRATROPICAL CYCLONE IN 36-48 HOURS.
AFTER COMPLETING A SMALL CYCLONIC LOOP...HARVEY APPEARS TO BE
RESUMING A NORTH-NORTHEASTWARD MOTION. THE ADVISORY MOTION IS
030/7. WATER VAPOR IMAGERY SHOWS THE NEXT SHORT WAVE IN THE
WESTERLIES OFF OF NEW ENGLAND IS PUSHING EASTWARD. THIS IS EXPECTED
TO HOOK UP WITH HARVEY IN ABOUT 24-36 HOURS AND INDUCE SOME
ACCELERATION TO THE NORTHEAST. GLOBAL MODELS NOW SUGGEST THAT LATE
IN THE FORECAST PERIOD HARVEY'S EXTRATROPICAL REMNANTS WILL COME
INTO PHASE WITH ANOTHER SHORT WAVE IN THE WESTERLIES AND CUT OFF.
THE OFFICIAL FORECAST IS SIMILAR TO THE PREVIOUS ADVISORY BUT
SLOWER AFTER 96 HOURS.
