WPAC: PAKHAR - Post-Tropical

[StormingB81]

Two of them popped up today this one is located 9N and 127E I am guess this could be the old 94W? Again no photo because of internet if I can get some help please and thank you.

THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 9.4N
123.3E, IS NOW LOCATED NEAR 9.1N 122.4E, APPROXIMATELY 130 NM NORTH
OF ZAMBOANGA, PHILIPPINES. ANIMATED INFRARED SATELLITE IMAGERY SHOWS
AN IMPROVING LLCC ASSOCIATED WITH FLARING DEEP CONVECTION. UPPER
LEVEL ANALYSIS INDICATES THE SYSTEM IS LOCATED JUST SOUTH OF THE
SUBTROPICAL RIDGE AXIS IN AN AREA OF MODERATE UPPER LEVEL DIVERGENCE
AND 15 TO 20 KNOTS OF VERTICAL WIND SHEAR. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW.

ECMWF shows development down the road...

[Typhoon Hunter]

ECM consistently developing this for the last 4 or 5 runs. I'd say it's got a good shot of becoming our basin's first named storm.

[wxman57]

Looks mighty unimpressive to me. I don't think anything will come of this disturbance.

THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 9.1N
122.4E, IS NOW LOCATED NEAR 9.3N 120.1E, APPROXIMATELY 175 NM
NORTHWEST OF ZAMBOANGA, PHILIPPINES. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY SHOWS A PARTIALLY EXPOSED LOW LEVEL CIRCULATION
CENTER (LLCC) OVER THE SULU SEA, WITH DEEP CONVECTION BEING SHEARED
TO THE NORTHWEST. ALTHOUGH THE 220000Z BOUNDARY LEVEL STREAMLINE
ANALYSIS AND MULTISPECTRAL IMAGERY INDICATE GOOD ORGANIZATION IN THE
LOW LEVELS, PROXIMAL SURFACE PRESSURE REPORTS AND THE MOST RECENT
SCATTEROMETRY DATA INDICATE THE CIRCULATION IS WEAK. A 212209Z SSMIS
IMAGE ALSO REVEALS A LACK OF BANDING IN THE LOW LEVEL CLOUD
FEATURES. THE UPPER LEVEL STREAMLINE ANALYSIS ALSO SHOWS THAT THE
LLCC IS WELL TO THE SOUTH OF THE SUBTROPICAL RIDGE, WHERE
APPROXIMATELY 20 KNOTS OF VERTICAL WIND SHEAR IS IMPEDING
DEVELOPMENT. SEA SURFACE TEMPERATURES ARE 28 TO 29 DEGREES. AS THE
SYSTEM CROSSES OVER PALAWAN AND INTO THE SOUTH CHINA SEA, IT WILL
RECEIVE A BOOST TO BOUNDARY LEVEL VORTICITY FROM THE NORTHEAST
MONSOON. POLEWARD MOVEMENT DURING THE NEXT 72 HOURS WILL
ALSO BRING THE LOW LEVEL CIRCULATION CENTER INTO A REGION OF
DECREASING VERTICAL WIND SHEAR, BUT OVER THE NEAR TERM THE VERTICAL
WIND SHEAR WILL CONTINUE TO IMPEDE DEVELOPMENT. ADDITIONALLY, MOST
GUIDANCE IS INDICATING THAT THE LLCC WILL BE DRIVEN EQUATORWARD IN
THE LONG TERM, WHICH WILL BRING THE LLCC INTO A REGION OF HIGHER
VERTICAL WIND SHEAR. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED
AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE
NEAR 1008 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW.

As each day passes, the forecast for this system keeps getting stronger and stronger.....now has a very small intense tropical cyclone...

[StormingB81]

(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 3.2N
143.8E, HAS DISSIPATED AND IS NO LONGER SUSPECT FOR THE DEVELOPMENT
OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS.

[euro6208]

better organized.

euro now showing a more southern landfall over vietnam.

[Typhoon Hunter]

Tropical depression now from JMA - TROPICAL DEPRESSION 1010 HPA AT 10N 115E NORTH SLOWLY.

ECM still develop it but spare Vietnam a direct hit in latest run.

and weaker too

[Typhoon Hunter]

...and now a much stronger system (35m/s at 850hPa) going on to impact Vietnam in latest ECM run. Didn't think I'd be eagerly checking model runs so early in the year!

If this does form will be first TS to form in SCS since 1965 (Sarah) according to Digital Typhoon database.

Upgraded to Medium.

THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 9.8N
115.6E, IS NOW LOCATED NEAR 8.3N 114.1E, APPROXIMATELY 210 NM NORTH-
NORTHWEST OF BRUNEI, BORNEO. ANIMATED INFRARED SATELLITE IMAGERY
SHOWS CONSOLIDATING CONVECTION OVER A WELL DEFINED LOW-LEVEL
CIRCULATION CENTER (LLCC). A SERIES OF RECENT SCATTEROMETRY PASSES
INDICATES 10-15 KNOT CENTRAL WINDS WITH 25-30 KNOT NORTHERLIES OVER
THE NORTHWESTERN QUADRANT OF THE LLCC ASSOCIATED WITH A MONSOONAL
SURGE. THE NORTHEAST MONSOON SURGE IS AIDING IN THE DEVELOPMENT OF
BOUNDARY LEVEL VORTICITY. UPPER-LEVEL ANALYSIS DEPICTS THE LLCC
APPROXIMATELY 5 DEGREES EQUATORWARD OF THE SUBTROPICAL RIDGE AXIS
UNDER WEAK TO MODERATE (10-15 KNOTS) SOUTHERLY VERTICAL WIND SHEAR
WITH GOOD DIVERGENCE ALOFT. SEA SURFACE TEMPERATURES REMAIN
FAVORABLE FOR DEVELOPMENT AT 28 DEGREES CELSIUS. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1008 MB. DUE TO THE CONTINUED
CONSOLIDATION OF CONVECTION OVER THE LLCC THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS UPGRADED TO MEDIUM.

A formation of a Tropical Cyclone along the West Philippine Sea, west of Palawan remains possible between March 28-April 01 (Wed-Sun).

T2K Tropical Cyclone Watch [As of 5:00 AM Tuesday March 27, 2012]:
Low Pressure Area (96W/1006 MB) getting stronger as it consolidates over the West Philippine Sea. Its rainbands will affect the Spratly Islands. Its center was located about 283 km SSW of Pagasa Island or 552 km WSW of Puerto Princesa (8.6N 113.8E)...max winds of 30-40 kph...moving WSW @ 11 kph. This disturbance is enhancing the strong Northeast Monsoon (aka. Amihan) - bringing windy & cloudy conditions w/ occasional rains & dangerously rough seas across Luzon, NCR, Bicol, Palawan, Northern & Eastern Visayas today.

[cycloneye]

Remains at Medium.

E AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 8.3N
114.1E, IS NOW LOCATED NEAR 7.9N 113.4E, APPROXIMATELY 205 NM NORTH-
NORTHWEST OF BANDAR SERI BEGAWAN, BRUNEI. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY SHOWS CONSOLIDATING CONVECTION OVER THE DEVELOPING
LOW-LEVEL CIRCULATION CENTER (LLCC). THE CONVECTIVE BANDING OBSERVED
IN SATELLITE IMAGERY HAS BEEN CONSOLIDATING OVER THE PAST SIX HOURS,
WITH MULTIPLE BANDS WRAPPING ALONG THE PERIMETER OF THE EASTERN AND
WESTERN HALVES. OBSERVATIONS IN THE VICINITY INDICATE THE WINDS
REMAIN IN THE 10 TO 15 KNOT RANGE. STRONGER WINDS ASSOCIATED WITH A
NORTHEASTERLY MONSOONAL SURGE (25-30 KNOTS) ARE LOCATED ALONG THE
NORTHWESTERN QUADRANT OF THE LLCC, BEGINNING TO ENHANCE THE LLCC.
UPPER LEVEL ANALYSIS DEPICTS THE LLCC IS APPROXIMATELY 5 DEGREES
EQUATORWARD OF THE SUBTROPICAL RIDGE AXIS, WHICH IS CREATING
MODERATE LEVELS OF VERTICAL WIND SHEAR (VWS) (10-15 KNOTS) AND GOOD
DIVERGENCE ALOFT. SEA SURFACE TEMPERATURES REMAIN FAVORABLE FOR
DEVELOPMENT AT 28 DEGREES CELSIUS. MAXIMUM SUSTAINED SURFACE WINDS
ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1008 MB. BASED ON SURFACE WINDS REMAINING WEAK
WITH MODERATE VWS, THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS MEDIUM.

SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
A 155 NM RADIUS OF 9.6N 113.7E WITHIN THE NEXT 12 TO 24 HOURS.
AVAILABLE DATA DOES NOT JUSTIFY ISSUANCE OF NUMBERED TROPICAL
CYCLONE WARNINGS AT THIS TIME. WINDS IN THE AREA ARE ESTIMATED TO
BE 18 TO 22 KNOTS. METSAT IMAGERY AT 280000Z INDICATES THAT A
CIRCULATION CENTER IS LOCATED NEAR 9.7N 113.7E. THE SYSTEM IS
MOVING EAST-NORTHEASTWARD AT 06 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 7.9N
113.4E, IS NOW LOCATED NEAR 9.7N 113.7E, APPROXIMATELY 290 NM NORTH-
NORTHWEST OF BANDAR SERI BEGAWAN, BRUNEI. RECENT ANIMATED
MULTISPECTRAL SATELLITE IMAGERY SHOWS CONTINUED CONSOLIDATION OF
CONVECTION OVER THE LOW-LEVEL CIRCULATION CENTER (LLCC). A 272234Z
SSMIS 37 GHZ IMAGE SHOWS THE LOW-LEVEL BANDING WRAPPING AROUND, AND
INTO, THE WESTERN EDGE OF THE LLCC. THERE IS POOR CONFIDENCE IN THE
CURRENT POSITION DUE TO THE DEGREE OF SPREAD IN PGTW, KNES, AND RJTD
CENTER FIX POSITIONS DURING THE SYSTEMS LIFE CYCLE. UPPER-LEVEL
ANALYSIS INDICATES THE LLCC IS APPROXIMATELY 5 DEGREES EQUATORWARD
OF THE SUBTROPICAL RIDGE AXIS, WHICH IS CREATING MODERATE LEVELS OF
VERTICAL WIND SHEAR (10-15 KNOTS). HOWEVER, IT SEEMS THAT EXCELLENT
DIVERGENCE ALOFT IS CURRENTLY OFFSETTING THE MODERATE VERTICAL WIND
SHEAR AND ALLOWING FOR PERSISTENT CENTRAL CONVECTION. ANIMATED WATER
VAPOR IMAGERY SHOWS THE MAJORITY OF OUTFLOW TO BE POLEWARD WITH
LITTLE EQUATORWARD EXHAUST. THE PRELIMINARY MODEL GUIDANCE DOES
SUGGEST A WEAK STEERING ENVIRONMENT DURING THE NEXT 12-24 HOURS WITH
A POSSIBLE LOOPING PATTERN BEFORE SUBTROPICAL RIDGING TO THE NORTH
BUILDS IN SUFFICIENTLY TO STEER THE SYSTEM GENERALLY WESTWARDS
TOWARDS VIETNAM. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18
TO 22 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008
MB. DUE TO INCREASED CONSOLIDATION OF CENTRAL CONVECTION AND THE
EXCELLENT DIVERGENCE ALOFT, THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS HIGH.
