AN AREA OF CONVECTION HAS PERSISTED NEAR 6.0S 90.9E,
APPROXIMATELY 1100 NM EAST OF DIEGO GARCIA. RECENT ANIMATED
INFRARED SATELLITE IMAGERY DEPICTS A BROAD LLCC WITH DEEP
CONVECTION CONFINED TO THE SOUTH IN AN AREA OF STRONG CONVERGENT
FLOW. SCATTEROMETER DATA FROM 161547Z DEPICTS A 15-20 KNOT WIND
FIELD TO THE SOUTH AND ONLY 5-10 KNOT WINDS OVER THE NORTHERN
PORTION OF THE SYSTEM. UPPER-LEVEL ANALYSIS INDICATES THE LLCC IS
LOCATED JUST NORTH OF THE STR AXIS UNDER WEAK (05-10 KNOT) VWS. SEA
SURFACE TEMPERATURES ARE CONDUCIVE FOR TROPICAL CYCLOGENESIS AT 26-
28 DEGREES CELSIUS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED
AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE
NEAR 1010 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.

1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
150 NM EITHER SIDE OF A LINE FROM 12.4S 77.0E TO 14.2S 72.0E
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 25 TO 30 KNOTS. METSAT IMAGERY AT
240200Z INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 12.8S
76.4E. THE SYSTEM IS MOVING SOUTHWESTWARD AT 07 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 12.0S
77.2E IS NOW LOCATED NEAR 12.8S 76.4E, APPROXIMATELY 405 NM
SOUTHEAST OF DIEGO GARCIA. ANIMATED INFRARED SATELLITE IMAGERY
DEPICTS A CONSOLIDATING LOW-LEVEL CIRCULATION CENTER (LLCC) WITH
IMPROVED CONVECTIVE BANDING OVER THE SOUTHERN SEMI-CIRCLE WRAPPING
INTO THE NORTHWEST QUADRANT. A 232203Z SSMI IMAGE INDICATES THAT
THE LLCC HAS BECOME MORE VERTICALLY ALIGNED OVER THE PAST SIX HOURS
DUE TO DECREASING VERTICAL WIND SHEAR, WHICH IS CURRENTLY AT 10 TO
15 KNOTS. UPPER-LEVEL ANALYSIS INDICATES THAT THE LLCC IS LOCATED
UNDER THE SUBTROPICAL WITH ENHANCED POLEWARD OUTFLOW ENHANCED BY
THE STRONG WESTERLIES LOCATED TO THE SOUTH. SEA SURFACE TEMPERATURES
IN THE AREA ARE FAVORABLE FOR DEVELOPMENT AT 28 TO 30 DEGREES
CELSIUS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 25 TO 30
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1002 MB.
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS HIGH.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED

This is now Moderate Tropical Storm Boldwin. At 06Z winds up to 45kts.

Interestingly there were advisories issued on this a week ago as 02R but they renumbered it to 03R when they resumed advisories yesterday.

2.C ADDITIONAL INFORMATIONS:
T=4.0- AND CI=4.0-
BOLDWIN HAS SHOWN A RAGGED EYE PATTERN DURING MOST OF THE DAY ON VIS IMAGERY. THE EYE WAS MORE INT
ERMITTENT ON EIR IMAGERY (BEST DEFINITION AT MIDDAY)
AVAILABLE DVORAK ESTIMATES AT 1130Z GIVE AN INITIAL INTENSITY AT 50 KT (SAB AND PGTW AT 3.5). HOWE
VER, A 3HR MEAN OF MANUAL T-NUM IS NEAR 4.0. MOREOVER, A 1039Z SSMI PASS DEPICTS A STRONG MID LEVE
L 20 NM DIAMETER EYE PATTERN ASSOCIATED WITH A CONTRACTING EYE. FINALLY, INITIAL INTENSITY ESTIMA
TE IS RAISED AT 55 KT.
THE SYSTEM IS COMPACT AND ENVIRONMENTAL PRESSURE ARE AROUND 1010 HPA. CONSEQUENTLY, MSLP IS HIGHER
THAN USUAL FOR A SYSTEM OF THAT STRENGTH.
ENVIRONMENTAL CONDITIONS ARE GOOD ALOFT THE CIRCULATION. THE WINDSHEAR IS WEAK UNDER THE UPPER LEV
EL RIDGE AXIS (LESS THAN 10 KT ACCORDING TO 09Z CIMSS ANALYSIS). HOWEVER A CIRRUS ARC IS DETECTED
SINCE 10Z OVER THE NORTHNORTHEASTERN OUTER CIRCULATION, SUGGESTING THAT A SOME SHEAR MAY STILL EXI
ST. UPPER LEVEL DIVERGENCE IS RATHER GOOD MAINLY POLEWARD. SST (IN THE 27-28C RANGE) AND OCEANIC H
EAT CONTAIN ARE ALSO FAVOURABLE FOR SOME FURTHER DEVELOPMENT.THIS RATHER FAVOURABLE ENVIRONMENTAL
CONDITIONS ARE EXPECTED TO CONTINUE UNTIL SUNDAY AFTERNOON.
AVAILABLE NWP GUIDANCE STRUGGLE TO PROPERLY HANDLE THE CURRENT INTENSIFICATION OF THIS SMALL SYSTE
M. THE CURRENT INTENSITY FORECAST IS ON THE PATH OF THE PREVIOUS ONE. CONFIDENCE IN THIS INTENSITY
FORECAST REMAINS LOWER THAN USUAL.
LATE SUNDAY, NORTHERLY THEN NORTH-WESTERLY VERTICAL WINDSHEAR IS EXPECTED TO STRENGTHEN AND SYSTEM
IS THEREFORE EXPECTED TO PROGRESSIVELY WEAKEN.
TUESDAY AND WEDNESDAY, THE SYSTEM SHOULD TRACK TOWARDS A POLAR TROUGH TRANSITING IN ITS SOUTH. AN
INTERACTION WITH THE UPPER LEVEL TROUGH THAT COULD MAINTAIN INTENSITY SEEMS POSSIBLE ACCORDING TO
NWP FIELDS. THIS SCENARIO IS HIGHLY UNCERTAIN ... IT IS WORTH NOTING THAT MOST OF THE ECMWF ENSEMB
LE MEMBERS DISSIPATE THE SYSTEM AS SOON AS TUESDAY ...

Ah yes you are right. I thought the area that was TD 2 was 96S as well but it looks like it was actually 95S. This is why I stick to the official RSMC numbers. :lol:

REMARKS:
252100Z POSITION NEAR 15.2S 71.2E.
TROPICAL CYCLONE 02S (BOLDWIN), LOCATED APPROXIMATELY 475 NM SOUTH
OF DIEGO GARCIA, HAS TRACKED WEST-SOUTHWESTWARD AT 09 KNOTS OVER
THE PAST SIX HOURS. ANIMATED MULTISPECTRAL AND INFRARED SATELLITE
IMAGERY DEPICT A FULLY-EXPOSED, RAPIDLY-WEAKENING LOW-LEVEL
CIRCULATION CENTER (LLCC) WITH DEEP CONVECTION SHEARED WELL
SOUTHEAST OF THE SYSTEM. A 251545Z SSMIS IMAGE INDICATES A POORLY-
DEFINED LLCC WITH AN ISOLATED AREA OF DEEP CONVECTION NEAR 15S
76E. A 250728Z OCEANSAT PARTIAL IMAGE SHOWED ONLY 20 TO 25 KNOTS
OVER THE SOUTHERN SEMI-CIRCLE. ADDITIONALLY, DVORAK FINAL-T INTENSITY ESTIMATES HAVE DECREASED TO 25 TO 30 KNOTS. THERE IS
LOW CONFIDENCE IN THE INITIAL POSITION BASED ON THE WEAK LLCC.
THE INITIAL INTENSITY IS HEDGED SLIGHTLY HIGHER THAN THE FINAL-T
ESTIMATES BASED ON THE HIGHER DVORAK CURRENT INTENSITY ESTIMATES.
TC 02S IS FORECAST TO TRACK WESTWARD AND DISSIPATE BY TAU 12.
THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON
WRNCEN PEARL HARBOR HI. THE SYSTEM WILL BE CLOSELY MONITORED FOR
SIGNS OF REGENERATION. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 251800Z IS 17 FEET.//
