REF/A/RMG/NAVPACMETOCCEN PEARL HARBOR HI/260321Z NOV 27//
AMPN/REF IS TROPICAL CYCLONE FORMATION ALERT (WTXS21 PGTW 260321)//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
160 NM EITHER SIDE OF A LINE FROM 7.7S4 94.8E1 TO 11.1S3 90.3E2
WITHIN THE NEXT 06 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 20 TO 25 KNOTS. METSAT
IMAGERY AT 270000Z9 INDICATES THAT A CIRCULATION CENTER IS
LOCATED NEAR 8.1S9 94.1E4. THE SYSTEM IS MOVING SOUTHWESTWARD AT
05 KNOTS.
2. REMARKS:
THE DISTURBANCE PREVIOUSLY LOCATED NEAR 8.4S2 95.5E9 IS NOW LOCATED
NEAR 8.1S9 94.1E4, APPROXIMATELY 295 NM NORTHWEST OF THE COCOS
ISLANDS. ANIMATED INFRARED AND VISIBLE SATELLITE IMAGERY INDICATES
CYCLING DEEP CONVECTION IN THE AREA. A RECENT TROPICAL RAINFALL
MEASURING MISSION (TRMM) PASS DEPICTS THE DEEP CONVECTION SHEARED
SOUTHWEST OF A WELL DEFINED LOW LEVEL CIRCULATION CENTER. THE 200 MB
ANALYSIS INDICATES THE REGION IS EQUATORWARD OF THE RIDGE AXIS IN A
REGION OF WEAK VERTICAL WIND SHEAR AND FAVORABLE OUTFLOW. MAXIMUM
SUSTAINED WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE 1002 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS REMAINS GOOD. THIS SUPERSEDES REF A.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
280330Z3.//

REMARKS:
270900Z8 POSITION NEAR 8.4S2 93.2E4.
TROPICAL CYCLONE (TC) 05S HAS DEVELOPED 320 NM NORTHWEST OF COCOS
ISLAND, OVER THE SOUTH INDIAN OCEAN. TC 05S HAS TRACKED WESTWARD AT
07 KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
270530Z7 VISIBLE SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON CURRENT SATELLITE INTENSITY ESTIMATES OF 30 AND 35 KNOTS. A MID-
LEVEL SUBTROPICAL RIDGE IS FORECAST TO BUILD IN EAST OF THE
SYSTEM THROUGH THE FORECAST PERIOD, WHICH WILL TRACK TC 05S TO THE
SOUTHWEST. THE AVAILABLE AIDS OF NOGAPS, THE UKMET GLOBAL (EGRR),
BETA ADVECTION MODELS, AND CLIMATOLOGY ARE ALL IN FAIR AGREEMENT
WITH A SOUTHWESTWARD TRACK. CLIMATOLOGY MODELS HAVE A WESTWARD
BIAS, WHILE EGRR DEPICTS THE MOST SOUTH-SOUTHWESTWARD TRACK. THE
SYSTEM IS FORECAST TO INTENSIFY AT A NEAR CLIMATOLOGICAL RATE
THROUGH THE PERIOD. WIND RADII ARE BASED ON CLIMATOLOGY FOR AN
AVERAGE SIZE SYSTEM AND A RECENT QUIKSCAT PASS. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 270600Z5 IS 12 FEET. THIS WARNING SUPERSEDES AND

REMARKS:
282100Z3 POSITION NEAR 11.1S3 91.3E3.
TROPICAL CYCLONE (TC) 05S (BESSI) IS CURRENTLY LOCATED OVER THE
SOUTH INDIAN OCEAN, APPROXIMATELY 330 NM WEST-NORTHWEST OF COCOS
ISLANDS, AND HAS TRACKED SOUTHWARD AT 08 KNOTS DURING THE PAST
SIX HOURS. THE WARNING POSITION IS BASED ON 281730Z1 INFRARED
SATELLITE IMAGERY AND RECENT MICROWAVE IMAGERY. THE WARNING
INTENSITY IS BASED ON CURRENT SATELLITE INTENSITY ESTIMATES OF 55
KNOTS. RECENT ANIMATED INFRARED IMAGERY REVEALS WEAKENING OF THE
SYSTEM AND SIGNIFICANT VERTICAL SHEAR OF CONVECTION. TC 05S HAS
TRACKED SOUTHWARD DURING THE PAST 12 HOURS IN A WEAKNESS CREATED BY
THE PASSAGE OF A MID-LATITUDE TROUGH. A MID-LEVEL SUBTROPICAL RIDGE
IS EXPECTED TO BUILD IN SOUTH OF THE SYSTEM THROUGH THE FORECAST
PERIOD AND TRACK TC 05S SOUTHWESTWARD. THE AVAILABLE AIDS OF NOGAPS,
THE UKMET GLOBAL (EGRR), AND NCEP AVIATION (AVN) ARE IN GOOD
AGREEMENT WITH A SOUTHWESTWARD TRACK. BASED ON CURRENT TRACK
FORECAST, THE SYSTEM IS EXPECTED TO MOVE TOWARDS A REGION OF WEAKER
SHEAR IN 12 TO 24 HOURS MORE FAVORABLE FOR THE SYSTEM. HOWEVER,
BASED ON THE RECENT WEAKENING TREND AND COOLER SEA SURFACE TEMPS
ALONG THE TRACK, A SLOW WEAKENING TREND IS FORECAST. WIND RADII ARE
BASED ON CLIMATOLOGY FOR AN AVERAGE SIZED SYSTEM. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 281800Z9 IS 15 FEET. NEXT WARNINGS AT

HAS TRACKED SOUTH-SOUTHEASTWARD AT 08 KNOTS DURING THE PAST SIX
HOURS. THE WARNING POSITION IS BASED ON 290530Z9 INFRARED AND
VISIBLE SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON CURRENT
SATELLITE INTENSITY ESTIMATES OF 45 AND 55 KNOTS. ANIMATED INFRARED
IMAGERY DEPICTS A PARTIALLY EXPOSED LOW-LEVEL CIRCULATION CENTER
WITH ASSOCIATED DEEP CONVECTION DISPLACED EQUATORWARD FROM THE
VORTEX CENTER. TC 05S HAS TRACKED SOUTH-SOUTHEASTWARD DURING THE
PAST 12 HOURS IN A WEAKNESS IN THE MID-LATITUDE RIDGE. A MID-LEVEL
SUBTROPICAL RIDGE IS EXPECTED TO BUILD IN SOUTH OF THE SYSTEM LATER
IN THE FORECAST PERIOD CAUSING TC 05S TO TURN GRADUALLY
SOUTHWESTWARD. THE AVAILABLE AIDS OF NOGAPS, THE UKMET GLOBAL
(EGRR), AND NCEP AVIATION (AVN) AGREE WITH THE AFOREMENTIONED
SCENARIO. TC 05S WILL BEGIN TO ENTER COOLER SEA SURFACE TEMPERATURES
ALONG ITS TRACK, RESULTING IN A SLOW WEAKENING TREND. WIND RADII ARE
BASED ON CLIMATOLOGY FOR AN AVERAGE SIZED SYSTEM. MAXIMUM

REMARKS:
012100Z4 POSITION NEAR 15.5S1 85.5E8
TROPICAL CYCLONE (TC) 05S (BESSI-BAKO) IS CURRENTLY LOCATED OVER THE
SOUTH INDIAN OCEAN, APPROXIMATELY 760 NM WEST-SOUTHWEST OF COCOS
ISLANDS, AND HAS BEEN DRIFTING SOUTHWARD AT 02 KNOTS DURING THE PAST
SIX HOURS. THE WARNING POSITION IS BASED ON 011730Z2 SATELLITE
IMAGERY. THE WARNING INTENSITY IS BASED ON CURRENT SATELLITE
INTENSITY ESTIMATES OF 55 AND 65 KNOTS. A RECENT SPECIAL SENSOR
MICROWAVE IMAGE DEPICTS A BANDING EYE FEATURE. THE SYSTEM IS NOW
UNDER THE UPPER LEVEL RIDGE AXIS IN A REGION OF FAVORABLE VERTICAL
WIND SHEAR. TC 05S WILL CONTINUE TO TRACK SOUTHWESTWARD THROUGH THE
FORECAST PERIOD AS A MID-LEVEL RIDGE BUILDS AND WILL GUIDE THE
SYSTEM TO THE SOUTHWEST. THE AVAILABLE AIDS CONSISTING OF NOGAPS,
THE UKMET GLOBAL (EGRR), AND NCEP AVIATION (AVN) ARE IN GOOD
AGREEMENT WITH THIS SOLUTION. GEOPHYSICAL FLUID DYNAMICS NAVY (GFDN)
MODEL IS AN OUTLIER TRACKING THE SYSTEM SOUTHEASTWARD THROUGH THE
PERIOD. THE FORECAST TRACK IS BASED ON A BLEND OF THE AFOREMENTIONED
MODELS AND THE MEDIUM BETA ADVECTION MODEL. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 011800Z0 IS 15 FEET. NEXT WARNINGS AT 020900Z1 AND

REMARKS:
032100Z6 POSITION NEAR 18.8S7 86.5E9.
TROPICAL CYCLONE (TC) 05S (BESSI-BAKO) IS CURRENTLY LOCATED OVER THE
SOUTH INDIAN OCEAN, APPROXIMATELY 710 NM SOUTHWEST OF COCOS ISLANDS,
AND HAS TRACKED SOUTH-SOUTHEASTWARD AT 05 KNOTS DURING THE PAST SIX
HOURS. THE WARNING POSITION IS BASED ON 031730Z4 SATELLITE IMAGERY.
THE WARNING INTENSITY IS BASED ON CURRENT SATELLITE INTENSITY
ESTIMATES OF 55 TO 77 KNOTS. ANIMATED INFRARED AND VISIBLE SATELLITE
IMAGERY DEPICT A PARTIALLY EXPOSED LOW LEVEL CIRCULATION
CENTER. THE SYSTEM IS POLEWARD OF THE UPPER LEVEL RIDGE AXIS AND NOW
UNDER THE INFLUENCE OF MODERATE VERTICAL WIND SHEAR. TC 05S WILL
TRACK TO THE SOUTH-SOUTHEAST AND THEN MORE SOUTHWARD THROUGH THE
REMAINDER OF THE FORECAST PERIOD, UNDER THE STEERING INFLUENCE OF A
LOW TO MID-LEVEL RIDGE TO THE SOUTH. THE AVAILABLE AIDS CONSISTING
OF NOGAPS (NGPS), THE UKMET GLOBAL (EGRR), GEOPHYSICAL FLUID
DYNAMICS NAVY (GFDN), AND NCEP AVIATION (AVN) FALL INTO TWO
CLUSTERS. NGPS AND AVN TRACK THE SYSTEM TO THE WEST THEN SOUTH DUE
TO EXCESSIVE SHEARING. GFDN AND EGRR DO NOT INDICATE THE SAME DEGREE
OF SHEARING AND AS A RESULT TRACK THE SYSTEM MORE SOUTHWARD. OUR
FORECAST TRACK IS BASED ON A BLEND OF MODELS, THE BETA ADVECTION
MODELS, AND PERSISTENCE. TC 05S SHOULD CONTINUE TO SLOWLY WEAKEN AS
IT TRACKS UNDERNEATH UPPER LEVEL WESTERLIES AND UNFAVORABLE VERTICAL
WIND SHEAR. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 031800Z2 IS 18 FEET.

REMARKS:
040900Z3 POSITION NEAR 18.3S2 86.5E9.
TROPICAL CYCLONE (TC) 05S (BESSI-BAKO) IS CURRENTLY LOCATED OVER THE
SOUTH INDIAN OCEAN, APPROXIMATELY 700 NM SOUTHWEST OF COCOS ISLANDS,
AND HAS REMAINED QUASISTATIONARY DURING THE PAST TWELVE HOURS. THE
WARNING POSITION IS BASED ON 040530Z2 SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON CURRENT SATELLITE INTENSITY ESTIMATES OF 35 TO
55 KNOTS. ANIMATED INFRARED AND VISIBLE SATELLITE IMAGERY DEPICT A
FULLY EXPOSED LOW LEVEL CIRCULATION CENTER AND THE EFFECTS OF STRONG
VERTICAL WIND SHEAR. THE 200 MB ANALYSIS INDICATES THAT TC 05S IS
BENEATH UPPER LEVEL WESTERLIES ASSOCIATED WITH A LONG WAVE TROUGH
OVER THE SOUTH INDIAN OCEAN. TC 05S IS FORECAST TO TRACK SLOWLY
SOUTHWARD TO SOUTHWESTWARD THROUGH THE FORECAST PERIOD UNDER THE
STEERING INFLUENCE OF A LOW TO MID-LEVEL RIDGE TO THE SOUTH. THE
AVAILABLE DYNAMIC AIDS CONSISTING OF NOGAPS (NGPS), THE UKMET OFFICE
GLOBAL (EGRR), GEOPHYSICAL FLUID DYNAMICS NAVY (GFDN), AND NCEP
AVIATION (AVN) MODELS ARE IN FAIR AGREEMENT WITH THIS SCENARIO. OUR
FORECAST TRACK IS BASED ON A BLEND OF MODELS, THE SHALLOW BETA
ADVECTION MODEL, AND PERSISTENCE. TC 05S SHOULD CONTINUE TO WEAKEN
AS IT TRACKS INTO INCREASING VERTICAL WIND SHEAR AND COOLER SEA
SURFACE CONDITIONS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 040600Z0 IS
18 FEET. NEXT WARNINGS AT 042100Z7 AND 050900Z4.//
