SUBTROPICAL STORM GABRIELLE DISCUSSION NUMBER 1
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL072007
1100 PM EDT FRI SEP 07 2007
THE AIR FORCE RESERVE HURRICANE HUNTER INVESTIGATING THE LOW
PRESSURE AREA OFF THE SOUTHEASTERN U. S. COAST COULD NOT FIND A
WELL-DEFINED CIRCULATION...REPORTING INSTEAD A VERY ELONGATED
CENTER. SUBSEQUENT SATELLITE IMAGERY SUGGESTS THE CIRCULATION IS
SLIGHTLY BETTER DEFINED...BUT IS STILL BROAD AND ELONGATED. THE
AIRCRAFT FOUND 48 KT FLIGHT-LEVEL WINDS ABOUT 85 N MI NORTHEAST OF
THE CENTER AND A CENTRAL PRESSURE OF ABOUT 1011 MB. BASED ON THE
LARGE RADIUS OF MAXIMUM WINDS...THE CONVECTIVE STRUCTURE...AND THE
PROXIMITY OF AN UPPER-LEVEL LOW TO THE WEST-SOUTHWEST...THE SYSTEM
IS DESIGNATED A SUBTROPICAL STORM WITH WINDS OF 40 KT.
GABRIELL IS MOVING 300/8 BETWEEN A DEEP LAYER RIDGE OVER THE
NORTHWESTERN ATLANTIC AND AN UPPER-LEVEL LOW NEAR THE NORTHERN
BAHAMAS. THE DYNAMICAL MODELS FORECAST THE CYCLONE TO RECURVE
AROUND THE WESTERN END OF THE EASTWARD-MOVING RIDGE DURING THE
NEXT 48-72 HR. THE MODELS DISAGREE...HOWEVER...ON EXACTLY WHERE AND
WHEN THAT TURN WILL OCCUR. THE GFDL IS THE LEFTMOST SOLUTION WITH
A FORECAST TRACK INTO EASTERN SOUTH CAROLINA IN ABOUT 36 HR...
FOLLOWED BY A NORTHEASTWARD MOTION ACROSS EASTERN NORTH CAROLINA
INTO THE ATLANTIC. THE UKMET...NOGAPS...AND GFS CALL FOR LANDFALL
IN EASTERN NORTH CAROLINA IN 36-48 HR...FOLLOWED BY RECURVATURE
INTO THE ATLANTIC. THE GFDL TRACK MAY BE RESULTING FROM HAVING TOO
DEEP OF A VORTEX INITIALLY...WHICH RESULTS IN TOO MUCH STEERING
INFLUENCE FROM THE UPPER-LEVEL LOW. THUS...THE FORECAST TRACK
FOLLOWS THE MORE EASTWARD SCENARIO OF THE OTHER MODELS.
THERE ARE CURRENTLY MANY NEGATIVE FACTORS INVOLVED IN THE FUTURE
DEVELOPMENT OF GABRIELLE. THE STORM HAS COOLER AIR TO THE NORTH
AT LOW LEVELS...VERY DRY AIR TO THE SOUTH AND WEST AT THE UPPER
LEVELS...IS EXPERIENCING SOUTHERLY VERTICAL WIND SHEAR...AND IS
PASSING OVER WATERS THAT HAVE COOLED A FEW DEGREES OVER THE PAST
COUPLE OF DAYS. ON THE POSITIVE SIDE...THE SHEAR MAY DECREASE AS
GABRIELLE APPROACHES THE COAST...AND THIS COULD OCCUR OVER THE DEEP
WARM WATER OF THE GULF STREAM. THE SHIPS MODEL CALLS FOR A PEAK
INTENSITY OF 63 KT...THE GFDL 68 KT...AND THE HWRF 37 KT. GIVEN
ALL THE NEGATIVES...THE INTENSITY FORECAST WILL STAY ON THE LOW
SIDE OF THE GUIDANCE...CALLING FOR A PEAK INTENSITY OF 50 KT NEAR
LANDFALL. AFTER RECURVATURE...GABRIELLE SHOULD GRADUALLY MERGE
WITH A FRONTAL ZONE AND BECOME EXTRATROPICAL.
IT SHOULD BE NOTED THAT THERE IS A POSSIBILITY OF CENTER REFORMATION
DUE TO THE ELONGATED NATURE OF THE SYSTEM. WHILE SUCH REFORMATION
WOULD NOT CHANGE THE OVERALL STEERING PATTERN...IT COULD HAVE AN
AFFECT ON IF AND WHERE THE CENTER MAKES LANDFALL.

SUBTROPICAL STORM GABRIELLE DISCUSSION NUMBER 2
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL072007
500 AM EDT SAT SEP 08 2007
THE SATELLITE PRESENTATION OF GABRIELLE HAS IMPROVED EARLY THIS
MORNING. A CURVED CONVECTIVE BAND IS NOW LOCATED CLOSER TO THE
CENTER OF CIRCULATION OVER THE NORTHERN AND WESTERN QUADRANTS...
WHICH COULD BE AN INDICATION THAT GABRIELLE IS GRADUALLY ACQUIRING
TROPICAL CHARACTERISTICS. DVORAK INTENSITY CLASSIFICATIONS ARE
T 2.5/35 KT FROM SAB AND ST 2.5/35-40 KT FROM TAFB. BASED ON THIS...
GABRIELLE WILL REMAIN A SUBTROPICAL 40 KT STORM FOR THIS ADVISORY.
WHILE THE CYCLONE IS CURRENTLY OVER WARM WATERS...THE UPPER LEVEL
ENVIRONMENT IS NOT FAVORABLE FOR SIGNIFICANT STRENGTHENING.
THEREFORE...ONLY SLIGHT STRENGTHENING IS INDICATED AS GABRIELLE
APPROACHES THE COAST. THIS IS CONSISTENT WITH A BLEND OF THE
SHIPS...GFDL...AND HWRF INTENSITY GUIDANCE.
THE INITIAL MOTION IS 300/10. GABRIELLE IS SITUATED BETWEEN AN
UPPER-LEVEL LOW TO ITS SOUTHWEST AND A DEEP-LAYER RIDGE OVER THE
NORTHWESTERN ATLANTIC. AS THE UPPER-LEVEL LOW MOVES WESTWARD AND
WEAKENS...GABRIELLE WILL BE STEERED AROUND THE WESTERN PERIPHERY OF
THE RIDGE TOWARD THE COAST OF NORTH AND SOUTH CAROLINA IN THE NEXT
DAY OR TWO. THEREAFTER...GABRIELLE IS EXPECTED TO BE EMBEDDED
WITHIN THE MID-LATITUDE SOUTHWESTERLY FLOW RESULTING IN AN
ACCELERATION TOWARD THE NORTHEAST. BY DAYS 4 AND 5 GABRIELLE
SHOULD BE AN EXTRATROPICAL CYCLONE...MOVING AWAY FROM THE UNITED
STATES. THE OFFICIAL TRACK FORECAST IS CLOSE TO THE DYNAMICAL
MODEL CONSENSUS AND IS NOT SIGNIFICANTLY DIFFERENT FROM THE
PREVIOUS ADVISORY.
TROPICAL STORM WARNINGS WILL LIKELY BE REQUIRED LATER TODAY FOR A
PORTION OF THE TROPICAL STORM WATCH AREA.

SUBTROPICAL STORM GABRIELLE DISCUSSION NUMBER 2
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL072007
500 AM EDT SAT SEP 08 2007
THE SATELLITE PRESENTATION OF GABRIELLE HAS IMPROVED EARLY THIS
MORNING. A CURVED CONVECTIVE BAND IS NOW LOCATED CLOSER TO THE
CENTER OF CIRCULATION OVER THE NORTHERN AND WESTERN QUADRANTS...
WHICH COULD BE AN INDICATION THAT GABRIELLE IS GRADUALLY ACQUIRING
TROPICAL CHARACTERISTICS. DVORAK INTENSITY CLASSIFICATIONS ARE
T 2.5/35 KT FROM SAB AND ST 2.5/35-40 KT FROM TAFB. BASED ON THIS...
GABRIELLE WILL REMAIN A SUBTROPICAL 40 KT STORM FOR THIS ADVISORY.
WHILE THE CYCLONE IS CURRENTLY OVER WARM WATERS...THE UPPER LEVEL
ENVIRONMENT IS NOT FAVORABLE FOR SIGNIFICANT STRENGTHENING.
THEREFORE...ONLY SLIGHT STRENGTHENING IS INDICATED AS GABRIELLE
APPROACHES THE COAST. THIS IS CONSISTENT WITH A BLEND OF THE
SHIPS...GFDL...AND HWRF INTENSITY GUIDANCE.
THE INITIAL MOTION IS 300/10. GABRIELLE IS SITUATED BETWEEN AN
UPPER-LEVEL LOW TO ITS SOUTHWEST AND A DEEP-LAYER RIDGE OVER THE
NORTHWESTERN ATLANTIC. AS THE UPPER-LEVEL LOW MOVES WESTWARD AND
WEAKENS...GABRIELLE WILL BE STEERED AROUND THE WESTERN PERIPHERY OF
THE RIDGE TOWARD THE COAST OF NORTH AND SOUTH CAROLINA IN THE NEXT
DAY OR TWO. THEREAFTER...GABRIELLE IS EXPECTED TO BE EMBEDDED
WITHIN THE MID-LATITUDE SOUTHWESTERLY FLOW RESULTING IN AN
ACCELERATION TOWARD THE NORTHEAST. BY DAYS 4 AND 5 GABRIELLE
SHOULD BE AN EXTRATROPICAL CYCLONE...MOVING AWAY FROM THE UNITED
STATES. THE OFFICIAL TRACK FORECAST IS CLOSE TO THE DYNAMICAL
MODEL CONSENSUS AND IS NOT SIGNIFICANTLY DIFFERENT FROM THE
PREVIOUS ADVISORY.
TROPICAL STORM WARNINGS WILL LIKELY BE REQUIRED LATER TODAY FOR A
PORTION OF THE TROPICAL STORM WATCH AREA.

ABOUT 1115Z CAPTURED ONLY THE WESTERN HALF OF THE CIRCULATION...BUT
DID INDICATE SOME BELIEVABLE 40 KT RETRIEVALS BETWEEN ABOUT 60 AND
90 NMI FROM THE CENTER...SO THE ADVISORY INTENSITY REMAINS 40 KT.
EVEN THOUGH THE CONVECTION IS BECOMING MORE PERSISTENT NEAR THE
CENTER...THE STATUS REMAINS SUBTROPICAL GIVEN THAT THE RADIUS OF
MAXIMUM WINDS REMAINS LARGE. A SHIP WITH CALL SIGN DDSB2 RECENTLY
REPORTED WINDS OF 33 KT AND A PRESSURE OF 1011 MB ABOUT 20 NMI
NORTHWEST OF THE CENTER...SO THE CENTRAL PRESSURE IS LOWERED
SLIGHTLY TO 1009 MB. AN AIR FORCE RECONNAISSANCE AIRCRAFT IS
SCHEDULED TO INVESTIGATE GABRIELLE THIS AFTERNOON TO HELP US GET A
MORE THOROUGH LOOK AT THE WIND FIELD.
THE CENTER OF GABRIELLE IS MOVING JUST SLIGHTLY TO THE RIGHT OF THE
PREVIOUS OFFICIAL TRACK...AND THE INITIAL MOTION ESTIMATE IS
305/9...WHICH IS ALSO A TAD SLOWER THAN BEFORE. THE STORM
CONTINUES TO BE STEERED BY THE RIDGE TO ITS NORTHEAST...AND THE
FORECAST SCENARIO REMAINS THAT GABRIELLE WILL ROTATE AROUND THE
WESTERN PERIPHERY OF THIS RIDGE AND INTO THE MIDLATITUDE WESTERLIES
DURING THE NEXT 2-3 DAYS. THE LATEST MODEL GUIDANCE HAS GENERALLY
SHIFTED SLIGHTLY TO THE RIGHT...AND ESPECIALLY GIVEN THE INITIAL
MOTION...SO HAS THE OFFICIAL FORECAST. THE NEW TRACK IS CLOSE TO A
BLEND OF THE HWRF...GFDL...AND GFS AND SHOWS LANDFALL ALONG THE
OUTER BANKS IN ABOUT 36 HOURS. THE SPREAD IN THE MODELS IS
SUFFICIENTLY LARGE...HOWEVER...THAT A LANDFALL FARTHER EAST OR NO
LANDFALL OF THE CENTER AT ALL ARE BOTH POSSIBILITIES. AFTER
PASSING NEAR OR OVER EASTERN NORTH CAROLINA...GABRIELLE SHOULD MOVE
FAIRLY QUICKLY BACK OUT TO SEA AND BECOME EXTRATROPICAL BY DAY 4.
A SHORT WINDOW OF OPPORTUNITY EXISTS FOR GABRIELLE TO STRENGTHEN
BEFORE REACHING NORTH CAROLINA...SINCE THE CURRENT SOUTHEASTERLY
WIND SHEAR IS FORECAST BY THE GLOBAL MODELS TO TEMPORARILY LESSEN
TONIGHT BEFORE INCREASING AGAIN TOMORROW AS THE UPPER-LEVEL LOW TO
THE SOUTHWEST MOVES FARTHER AWAY. GIVEN THE LIMITED EXTENT OF THE
CONVECTION CURRENTLY...THAT CHANGE IN ENVIRONMENT IS PROBABLY NOT
ENOUGH TO WARRANT A FORECAST OF SIGNIFICANT STRENGTHENING. THE NEW
OFFICIAL FORECAST IS VERY SIMILAR TO THE PREVIOUS ADVISORY IN
BRINGING GABRIELLE TO 55 KT BY 36 HOURS...IN LINE WITH MOST OF THE
OBJECTIVE GUIDANCE. GRADUAL WEAKENING IS FORECAST BEYOND 72 HOURS

Re: Tropical Storm GABRIELLE (ATL): Advisories
TROPICAL STORM GABRIELLE DISCUSSION NUMBER 4
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL072007
500 PM EDT SAT SEP 08 2007
AFTER BEING BRIEFLY INVOLVED WITH THE CIRCULATION CENTER THIS
MORNING...THE CONVECTION HAS SPENT MOST OF THE DAY QUITE SEPARATED
FROM THE CENTER...AND THE BAND IN THE NORTHEASTERN QUADRANT HAS
DISSIPATED. RECENTLY...HOWEVER...THE CIRCULATION CENTER AND THE
REMAINING CONVECTION IN THE NORTHWESTERN QUADRANT ARE IN THE
PROCESS OF BEING REUNITED. GABRIELLE HAS TAKEN ON MORE OF
THE APPEARANCE OF A SHEARED TROPICAL CYCLONE...AND BOTH AMSU AND
AIRCRAFT DATA SUGGEST THERE IS A WEAK WARM CORE...SO GABRIELLE IS
BEING DESIGNATED AS A TROPICAL STORM ON THIS ADVISORY. MAXIMUM
WINDS FROM THE AIR FORCE PLANE AT THE FLIGHT-LEVEL OF ABOUT 1000 FT
WERE ONLY 39 KT...EVEN WITHIN THE CONVECTION IN THE NORTHWESTERN
QUADRANT. GIVEN THOSE DATA AND THE OVERALL LESSENING OF THE
CONVECTIVE DEPTH AND COVERAGE...THE INTENSITY IS LOWERED TO 35 KT.
THE CURRENT SOUTHEASTERLY SHEAR MIGHT STILL LESSEN TEMPORARILY
TONIGHT...BUT WILL INCREASE FROM THE NORTH TOMORROW. THAT WINDOW
OF OPPORTUNITY FOR STRENGTHENING IS THE BASIS FOR THE OFFICIAL
FORECAST TO STILL CALL FOR SLIGHT STRENGTHENING. THE NEW FORECAST
IS LOWERED COMPARED TO THE PREVIOUS ADVISORY...CALLING FOR
GABRIELLE TO REACH ONLY 45 KT NEAR THE COAST OF NORTH

AFTER BEING BRIEFLY INVOLVED WITH THE CIRCULATION CENTER THIS
MORNING...THE CONVECTION HAS SPENT MOST OF THE DAY QUITE SEPARATED
FROM THE CENTER...AND THE BAND IN THE NORTHEASTERN QUADRANT HAS
DISSIPATED. RECENTLY...HOWEVER...THE CIRCULATION CENTER AND THE
REMAINING CONVECTION IN THE NORTHWESTERN QUADRANT ARE IN THE
PROCESS OF BEING REUNITED. GABRIELLE HAS TAKEN ON MORE OF
THE APPEARANCE OF A SHEARED TROPICAL CYCLONE...AND BOTH AMSU AND
AIRCRAFT DATA SUGGEST THERE IS A WEAK WARM CORE...SO GABRIELLE IS
BEING DESIGNATED AS A TROPICAL STORM ON THIS ADVISORY. MAXIMUM
WINDS FROM THE AIR FORCE PLANE AT THE FLIGHT-LEVEL OF ABOUT 1000 FT
WERE ONLY 39 KT...EVEN WITHIN THE CONVECTION IN THE NORTHWESTERN
QUADRANT. GIVEN THOSE DATA AND THE OVERALL LESSENING OF THE
CONVECTIVE DEPTH AND COVERAGE...THE INTENSITY IS LOWERED TO 35 KT.
THE CURRENT SOUTHEASTERLY SHEAR MIGHT STILL LESSEN TEMPORARILY
TONIGHT...BUT WILL INCREASE FROM THE NORTH TOMORROW. THAT WINDOW
OF OPPORTUNITY FOR STRENGTHENING IS THE BASIS FOR THE OFFICIAL
FORECAST TO STILL CALL FOR SLIGHT STRENGTHENING. THE NEW FORECAST
IS LOWERED COMPARED TO THE PREVIOUS ADVISORY...CALLING FOR
GABRIELLE TO REACH ONLY 45 KT NEAR THE COAST OF NORTH
CAROLINA...AND THIS IS CONSISTENT WITH MOST OF THE GUIDANCE.
LITTLE CHANGE IN STRENGTH IS FORECAST ONCE GABRIELLE TURNS
NORTHEASTWARD AND EVENTUALLY BECOMES EXTRATROPICAL.

Re: Tropical Storm GABRIELLE (ATL): Advisories
TROPICAL STORM GABRIELLE DISCUSSION NUMBER 5
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL072007
1100 PM EDT SAT SEP 08 2007
THE LOW-LEVEL CENTER OF GABRIELLE HAS DISAPPEARED UNDER A CIRRUS
OVERCAST CAUSED BY A STRONG CONVECTIVE BURST...WHICH INCLUDED A
SUPERCELL THUNDERSTORM WITH A WELL-DEFINED MESOCYCLONE ON THE
MOREHEAD CITY WSR-88D. THE BURST HAS ENDED FOR NOW...BUT HAS LEFT
A MID-LEVEL CIRCULATION EVIDENT IN THE DOPPLER RADAR DATA. WHILE
THE RADAR WINDS DO NOT YET SHOW AN OBVIOUS INCREASE IN INTENSITY...
A RECENT QUIKSCAT OVERPASS SHOWED A FEW 40-45 KT WIND VECTORS THAT
WERE POSSIBLY RAIN CONTAMINATED. THE INITIAL INTENSITY REMAINS 35
KT...AND IT IS POSSIBLE THIS IS A LITTLE CONSERVATIVE.
THE SURFACE CENTER IS DIFFICULT TO LOCATE IN BOTH SATELLITE AND
RADAR IMAGERY...BUT IS ESTIMATED TO BE A LITTLE TO THE EAST OR
SOUTHEAST OF THE MID-LEVEL CENTER. THIS MAKES THE INITIAL MOTION A
SOMEWHAT UNCERTAIN 325/10. THERE IS LITTLE CHANGE TO THE TRACK
FORECAST PHILOSOPHY OTHER THAN THE SLIGHTLY MORE WESTERLY POSITION.
GABRIELLE SHOULD TURN NORTHWARD AROUND THE WESTERN SIDE OF A
DEEP-LAYER RIDGE OVER THE WESTERN ATLANTIC DURING THE NEXT 12-24
HR. BEYOND THAT TIME...IT SHOULD ACCELERATE NORTHEASTWARD INTO THE
WESTERLIES.
THE CENTER OF GABRIELLE IS PASSING OVER THE GULF STREAM...AND THE
VERTICAL WIND SHEAR THAT WAS AFFECTING THE SYSTEM EARLIER IS
DIMINISHING. BASED ON THIS...THE INTENSITY FORECAST CALLS FOR SOME
STRENGTHENING BEFORE THE CENTER REACHES THE NORTH CAROLINA COAST.
GABRIELLE IS FORECAST TO MAINTAIN INTENSITY DURING EXTRATROPICAL
TRANSITION...AND IT SHOULD BE ABSORBED BY A LARGER EXTRATROPICAL
LOW BETWEEN 72-96 HR.
