ATL: GABRIELLE - Remnants - Discussion

[HurricaneBelle]

Looks like the shear has let up and Gabby's getting some of her convection back, much closer to the center this time around.

[Extratropical94]

She's a storm again!

TROPICAL STORM GABRIELLE DISCUSSION NUMBER 18
NWS NATIONAL HURRICANE CENTER MIAMI FL AL072013
500 PM AST THU SEP 12 2013

GABRIELLE CONSISTS OF A TIGHT SWIRL OF LOW CLOUDS STILL PRODUCING
INTERMITTENT DEEP CONVECTION TO THE NORTH AND EAST OF THE CENTER.
EARLIER SATELLITE DATA INDICATE THAT THERE ARE A FEW 35-KNOT WIND
VECTORS TO THE NORTHEAST OF THE CENTER ASSOCIATED WITH THE
CIRCULATION...AND THIS VALUE IS USED AS THE INITIAL INTENSITY.
LITTLE CHANGE IN STRENGTH IS ANTICIPATED DURING THE NEXT 12 HOURS.
AFTER THAT TIME...WEAKENING IS FORECAST...AND GABRIELLE WILL LIKELY
BE ABSORBED BY A FRONTAL SYSTEM.

GABRIELLE IS MOVING TOWARD THE NORTH OR 350 DEGREES AT 7 KNOTS AHEAD
OF A DEVELOPING MID-LATITUDE TROUGH OVER THE EASTERN UNITED STATES.
THIS PATTERN WILL FORCE GABRIELLE TO RECURVE AND TURN TO THE
NORTH-NORTHEAST WITH AN INCREASE IN FORWARD SPEED AS INDICATED IN
THE NHC FORECAST.


FORECAST POSITIONS AND MAX WINDS

INIT 12/2100Z 34.4N 67.9W 35 KT 40 MPH
12H 13/0600Z 36.3N 67.7W 35 KT 40 MPH
24H 13/1800Z 40.5N 66.0W 30 KT 35 MPH
36H 14/0600Z...ABSORBED BY A FRONT

TROPICAL STORM GABRIELLE DISCUSSION NUMBER 19
NWS NATIONAL HURRICANE CENTER MIAMI FL AL072013
1100 PM AST THU SEP 12 2013

ONCE AGAIN DEEP CONVECTION HAS LARGELY DISAPPEARED NEAR THE CENTER
OF GABRIELLE. THE INITIAL INTENSITY REMAINS 35 KT...BUT THIS COULD
BE GENEROUS. WEAKENING IS FORECAST AS THE CYCLONE ACCELERATES
NORTHEASTWARD AND IS ABSORBED BY A FRONTAL SYSTEM IN 36 HOURS OR
PERHAPS A LITTLE SOONER.

GABRIELLE IS NOW MOVING TOWARD THE NORTH-NORTHEAST OR 015 DEGREES AT
ABOUT 9 KNOTS AHEAD OF A DEVELOPING MID-LATITUDE TROUGH OVER THE
EASTERN UNITED STATES. GABRIELLE SHOULD CONTINUE TO ACCELERATE
NORTH-NORTHEASTWARD ON FRIDAY...AND THE NHC TRACK IS IN GOOD
AGREEMENT WITH THE MODEL GUIDANCE THROUGH DISSIPATION.

FORECAST POSITIONS AND MAX WINDS

INIT 13/0300Z 35.1N 67.7W 35 KT 40 MPH
12H 13/1200Z 38.0N 66.8W 30 KT 35 MPH
24H 14/0000Z 43.8N 64.3W 30 KT 35 MPH...POST-TROP/EXTRATROP
36H 14/1200Z...DISSIPATED

I'm hoping this can hold out as a tropical storm at least long enough for TD10 to get named, as this may be the only chance to have three storms active at once.

TROPICAL DEPRESSION GABRIELLE DISCUSSION NUMBER 20
NWS NATIONAL HURRICANE CENTER MIAMI FL AL072013
500 AM AST FRI SEP 13 2013

ALTHOUGH DEEP CONVECTION HAS INCREASED TO THE NORTH OF THE CENTER OF
GABRIELLE DURING THE LAST FEW HOURS...IT LACKS BANDING FEATURES. AN
ASCAT OVERPASS AROUND 0200 UTC SHOWED MAXIMUM WINDS IN THE 25 TO 30
KT RANGE...AND ALL OF THE SATELLITE INTENSITY ESTIMATES SUPPORT AN
INTENSITY OF 30 KT OR LOWER. BASED ON THESE DATA...GABRIELLE IS
ONCE AGAIN DOWNGRADED TO A 30-KT TROPICAL DEPRESSION.

GABRIELLE IS MOVING A LITTLE FASTER THAN IT WAS EARLIER...WITH THE
LATEST INITIAL MOTION ESTIMATE BEING 015/15. THE CYCLONE IS
EXPECTED TO ACCELERATE TO THE NORTH-NORTHEAST LATER TODAY WHEN IT
BECOMES MORE EMBEDDED IN THE STRONG FLOW ON THE EAST SIDE OF A
DEEP-LAYER TROUGH OVER THE EASTERN UNITED STATES AND CANADA.
GABRIELLE IS FORECAST TO DEGENERATE INTO A TROUGH IN 12 TO 24 HOURS
BEFORE IT IS ABSORBED BY A COLD FRONT. SOME OF THE DYNAMICAL MODELS
SHOW DISSIPATION OCCURRING EVEN SOONER THAN FORECAST.

FORECAST POSITIONS AND MAX WINDS

INIT 13/0900Z 36.5N 67.5W 30 KT 35 MPH
12H 13/1800Z 40.5N 65.8W 30 KT 35 MPH
24H 14/0600Z...DISSIPATED

I'm tracking Gabby on my weather blog -

http://hybridstorm-weatherblog.blogspot.ca/

I'll post another update in about two hours, every three hours now moving forward, or when the center makes landfall whichever comes first.

[HurricaneBelle]

"Remnants of Gabrielle" sounds like the name of a really bad emo band.

[Hybridstorm_November2001]

Gabrielle, now extratropical, makes landfall in Eastern Nova Scotia -
