SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN A
070 NM RADIUS OF 14.2S 128.4E 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 180530Z INDICATES THAT A CIRCULATION
CENTER IS LOCATED NEAR 14.2S 128.5E.  THE SYSTEM IS MOVING SOUTH-
EASTWARD AT 06 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 13.0S
127.8E, IS NOW LOCATED NEAR 14.2S 128.5E, APPROXIMATELY 175 NM SOUTH-
WEST OF DARWIN, AUSTRALIA. RECENT ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS A LOW LEVEL CIRCULATION CENTER THAT IS BEGINNING TO
HAVE DEEP CONVECTIVE BANDING WRAPPING TOWARDS THE CENTER, WHICH IS
ALSO APPARENT IN ANIMATED RADAR IMAGERY. THE SYSTEM IS IN AN REGION
OF LOW VERTICAL WIND SHEAR WITH FAVORABLE UPPER LEVEL OUTFLOW
SUPPORT AND FAVORABLE SEA SURFACE TEMPERATURES. THE CURRENT LIMITING
FACTOR IS THE SYSTEMS PROXIMITY TO LAND, CURRENTLY BETWEEN 30 TO
60 NM FROM LANDFALL.  AT CURRENT TRACK AND SPEED LANDFALL COULD
OCCUR WITHIN THE NEXT 10 TO 12 HOURS. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 27 TO 32 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1000 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED
BY 190830Z.//

REMARKS:
181500Z POSITION NEAR 14.5S 128.9E.
TROPICAL CYCLONE (TC) 05S (BILLY), LOCATED APPROXIMATELY 165 NM
SOUTHWEST OF DARWIN, AUSTRALIA, HAS TRACKED SOUTHEASTWARD AT 05 KNOTS
OVER THE PAST 06 HOURS. RECENT ANIMATED INFRARED SATELLITE IMAGERY
AND ANIMATED RADAR IMAGERY INDICATES THAT THE LOW LEVEL CIRCULATION
CENTER (LLCC) HAS CONTINUED TO CONSOLIDATE, WITH DEEP CONVECTION
PERSISTING AND A SLOWING OF THE TRACK SPEED AS IT HAS STARTED TO
TURN SOUTHWARD. THE MOST RECENT INTENSITY ESTIMATES HAD THE SYSTEM
AT A MINIMUM OF 30 KNOTS, ALONG WITH COASTAL OBSERVATIONS NEAR TC
05S, THE INTENSITY HAS BEEN CONTINUING TO INCREASE OVER THE PAST 12
HOURS. UPPER LEVEL ANALYSIS SHOW GOOD OUTFLOW IN THE EQUATORWARD AND
POLEWARD CHANNELS, AND LOW VERTICAL WIND SHEAR. SEA SURFACE
TEMPERATURES ARE GOOD IN THE VICINITY OF TC 05S HELPING TO INTENSIFY
THE SYSTEM. THE ONLY LIMITING FACTOR IS THE PROXIMITY TO LAND. THE
FORECAST HAS THE SYSTEM SLOWLY TRACKING TO THE SOUTH AS IT SHIFTS
ITS TRACK TO THE SOUTHWEST, WHICH IS IDENTIFIABLE IN RADAR IMAGERY.
THE SYSTEM IS FORECAST TO MAKE LANDFALL WITHIN 24 HOURS, LIMITING
INTENSIFICATION, AND WILL LEAD TO WEAKENING AS IT TRACKS OVER LAND.

REMARKS:
211500Z POSITION NEAR 15.5S 125.1E.
TROPICAL CYCLONE (TC) 05S (BILLY), LOCATED APPROXIMATELY 760 NM
EAST-NORTHEAST OF LEARMONTH, AUSTRALIA, HAS TRACKED WEST-
SOUTHWESTWARD AT 03 KNOTS OVER THE PAST SIX HOURS. RECENT RADAR DATA 
FROM WYNDHAM, AUSTRALIA, AND NEARBY SURFACE OBSERVATIONS INDICATE 
THAT TC 05S HAS MAINTAINED GOOD LOW LEVEL STRUCTURE. INITIAL 
INTENSITY IS BASED UPON THE AFOREMENTIONED SURFACE OBSERVATIONS 
TAKEN APPROXIMATELY 60 NM TO THE NORTHEAST OF THE STORM CENTER WHICH 
DEPICT SUSTAINED NORTHWESTERLY WINDS RANGING FROM 17 TO 24 KNOTS 
OVER THE PAST 12 HOURS. THE CYCLONE IS TRACKING WESTWARD ALONG THE 
NORTHERN PERIPHERY OF A SUBTROPICAL RIDGE EXTENSION TO THE SOUTH. 
GENERALLY WESTWARD TO WEST-SOUTHWESTWARD MOTION ALONG THE CURRENT 
STEERING RIDGE PERIPHERY IS EXPECTED TO CONTINUE THROUGH THE 
FORECAST PERIOD. TC 05S WILL REEMERGE OVER VERY WARM WATER NEAR TAU 
12 AND MOVE BENEATH THE AXIS OF AN UPPER LEVEL ANTICYCLONE, INTO A 
LOW VERTICAL WIND SHEAR AND STRONG OUTFLOW ENVIRONMENT. THESE 
FAVORABLE INFLUENCES WILL ALLOW THE CYCLONE TO STEADILY INTENSIFY 
THROUGH TAU 72. NEXT WARNINGS AT 220300Z AND 221500Z. REFER TO 
TROPICAL CYCLONE 04S (CINDA) WARNINGS (WTXS31 PGTW) FOR THE FINAL 
WARNING ON THAT SYSTEM.

REMARKS:
220300Z POSITION NEAR 15.6S 124.0E.
TROPICAL CYCLONE (TC) 05S (BILLY) LOCATED APPROXIMATELY 700 NM EAST-
NORTHEAST OF LEARMONTH, AUSTRALIA, HAS TRACKED WESTWARD AT 05 KNOTS
OVER THE PAST SIX HOURS. TC 05S HAS CROSSED THE KIMBERLY COAST INTO
THE INDIAN OCEAN NEAR KURI BAY. TC 05S CONTINUES TO TRACK GENERALLY
WESTWARD ON THE EQUATORWARD PERIPHERY OF THE MID-LEVEL STEERING
RIDGE TO THE SOUTHEAST OVER CENTRAL AUSTRALIA, WHICH WILL CONTINUE
TO GENERATE A WESTWARD TRACK THROUGHOUT THE FORECAST PERIOD.
TROUGHING TO THE SOUTHWEST OF AUSTRALIA IS EXPECTED TO CAUSE THE
WESTERN EXTENSION OF THE STEERING RIDGE TO RETREAT EASTWARD NEAR TAU
24, RESULTING IN A MORE WEST-SOUTHWESTWARD TRACK. INTENSIFICATION IS
EXPECTED TO BE SLOW, DUE TO INTERACTION WITH LAND IN THE THE NEAR
TERM, AND INHIBITION DUE TO THE DEVELOPING SYSTEM IN THE GULF OF
CARPENTARIA. AFTER TAU 48, INTENSIFICATION WILL CONTINUE TO BE SLOW
DUE TO INCREASING VERTICAL WINDSHEAR AND DECREASING SEA SURFACE
TEMPERATURES. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 220000Z IS 12 FEET.

REMARKS:
221500Z POSITION NEAR 16.4S 123.1E.
TROPICAL CYCLONE (TC) 05S (BILLY) LOCATED APPROXIMATELY 640 NM EAST-
NORTHEAST OF LEARMONTH, AUSTRALIA, HAS TRACKED SOUTHWESTWARD AT 06
KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY
INDICATES THAT THE SYSTEM HAS TRACKED SLIGHTLY SOUTH OF THE PREVIOUS
FORECAST CLOSER TO THE KIMBERLY COASTLINE. AS A RESULT, INTENSITY
ESTIMATES FROM PGTW AND APRF HAVE STEADIED AROUND A 35 TO 45 KNOT
SYSTEM OVER THE PAST 12 HOURS. THE CURRENT POSITION IS BASED ON
THE BROOME RADAR LOOP INDICATING THE TIGHTEST TURNING TO THE
EAST-SOUTHEAST OF CAPE LEVEQUE, WITHIN CONE BAY. TO A LESSER DEGREE
INFRARED POSITION FIXES FROM PGTW AND APRF HAVE ALSO SUPPLEMENTED
IN POSITIONING OF THE CYCLONE. THE SYSTEM IS LOCATED EQUATORWARD OF
THE MID-LEVEL SUBTROPICAL STEERING RIDGE THAT IS CURRENTLY ORIENTED
NORTHEAST TO SOUTHWEST. THIS ORIENTATION WILL GRADUALLY SHIFT MORE
EAST TO WEST AFTER TAU 36 IN RESPONSE TO PREVAILING EAST TO SOUTH-
EASTERLY FLOW IN THE MID TO UPPER LEVELS. THIS FLOW WILL FACILITATE
FURTHER SEPARATION DISTANCE FROM THE COAST ALLOWING THE CYCLONE TO
MAKE SWIFT INTENSITY GAINS IN FAVORABLE SEAS AND UNDER CONDUCIVE
UPPER LEVEL CONDITIONS. THIS FORECAST IS BASED ON THE CONSENSUS OF
THE AVAILABLE MODEL AIDS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 221200Z
IS 13 FEET. NEXT WARNINGS AT 230300Z AND 231500Z.

REMARKS:
230300Z POSITION NEAR 17.5S 121.9E.
TROPICAL CYCLONE (TC) 05S (BILLY) LOCATED APPROXIMATELY 525 NM EAST-
NORTHEAST OF LEARMONTH, AUSTRALIA, HAS TRACKED SOUTHWESTWARD AT 08
KNOTS OVER THE PAST SIX HOURS. THE TWELVE-HOUR TIME LAPSE ON ANIMATED
INFRARED SATELLITE IMAGERY AND WEATHER RADAR COMPOSITE REFLECTIVITY
LOOP FROM BROOME, AUSTRALIA SHOW THAT THE LOW LEVEL CIRCULATION
CENTER (LLCC) HAS DRIFTED ACROSS KING SOUND AND IS NOW OVER THE
NORTHERN TIP OF DAMPIER PENINSULA. IN ADDITION, SPIRAL BAND
CONVECTION AROUND THE LLCC THAT HAD DEEPENED OVER THE SOUND HAS
SLIGHTLY DECREASED AFTER INTERACTING WITH THE LAND MASS. THE
CURRENT CENTRAL WIND SPEED IS BASED ON SATELLITE INTENSITY FIXES FROM
PGTW AND APRF, AND EXTRAPOLATED FROM NEARBY SURFACE OBSERVA-TIONS.
MID AND UPPER LEVEL ANALYSES INDICATE THE SYSTEM IS IN AN AREA OF
LIGHT VERTICAL WIND SHEAR AND GOOD DIFFLUENCE ALOFT, AS EVIDENCED ON
ANIMATED WATER VAPOR IMAGERY. TC 05S IS TRACKING ALONG THE
NORTHWESTERN PERIPHERY OF A 700 MB RIDGE. THIS RIDGE IS EXPECTED TO
BUILD AND REORIENT ON A MORE WEST-TO-EAST AXIS AFTER TAU 36 CAUSING
THE SYSTEM TO VEER ON A WESTWARD DIRECTION. THIS FLOW WILL HASTEN THE
SEPARATION DISTANCE FROM THE COAST ALLOWING THE CYCLONE TO MAKE
GRADUAL INTENSITY GAINS OVER WARM SEAS AND UNDER FAVORABLE UPPER
LEVEL CONDITIONS. THE MAJORITY OF FORECAST MODEL AIDS ARE IN
AGREEMENT WITH THIS SCENARIO. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
230000Z IS 12 FEET. NEXT WARNINGS AT 231500Z AND 240300Z.//

REMARKS:
231500Z POSITION NEAR 17.7S 120.5E.
TROPICAL CYCLONE (TC) 05S (BILLY), LOCATED APPROXIMATELY 465 NM
NORTHEAST OF LEARMONTH, AUSTRALIA, HAS TRACKED WESTWARD AT 05 KNOTS 
OVER THE PAST SIX HOURS. RECENT ANIMATED RADAR IMAGERY FROM BROOME, 
AUSTRALIA, AS WELL AS MICROWAVE AND GEOSTATIONARY SATELLITE POSITION 
ESTIMATES, INDICATE THAT TC 05S HAS BEGUN AN ANTICIPATED WESTWARD 
TURN DURING THE PAST 12 HOURS. THE CYCLONE IS NOW TRACKING WESTWARD 
UNDER THE STEERING INFLUENCE OF A VERTICALLY DEEP SUBTROPICAL RIDGE 
EXTENSION TO THE SOUTH. FORWARD MOTION HAS SLOWED AS THE SYSTEM 
NEARS A WEAKNESS BETWEEN THE CURRENT STEERING RIDGE AND A SECOND 
SUBTROPICAL RIDGE TO THE WEST. BY TAU 24, THE SECOND RIDGE TO THE 
WEST IS EXPECTED TO EXERT AN INCREASING INFLUENCE ON STORM MOTION,
CARRYING THE SYSTEM ON A WEST-NORTHWESTWARD TRACK AWAY FROM THE 
WESTERN AUSTRALIA COAST. THIS TRACK FORECAST IS SUPPORTED BY ALL OF 
THE AVAILABLE NUMERICAL MODEL GUIDANCE. FORWARD TRACK SPEEDS HAVE 
BEEN DECREASED SLIGHTLY FROM THE PREVIOUS FORECAST GIVEN THE CURRENT 
SLOWDOWN AND THE ANTICIPATED CHANGE OF PRIMARY STEERING INFLUENCE. 
TC 05S WILL INTENSIFY STEADILY OVER THE NEXT 36 HOURS AS THE STORM 
MOVES UNDER AN UPPER LEVEL ANTICYCLONE AXIS INTO A REGION OF LOW TO 
MODERATE VERTICAL WIND SHEAR SHEAR AND STRONG POLEWARD OUTFLOW. 
AFTER TAU 36, STORM INTENSITY WILL BEGIN TO DECREASE AS INCREASING 
VERTICAL WIND SHEAR AND PASSAGE OVER SOMEWHAT COOLER WATER TAKE 
THEIR TOLL. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 231200Z IS 13 FEET.

OVER THE PAST SIX HOURS AS SHOWN ON LATEST RADAR IMAGE LOOP FROM
BROOME, AUSTRALIA. ANIMATED MULTISPECTRAL SATELLITE IMAGERY INDI-
CATES THE STORM HAS RAPIDLY INTENSIFIED AS A 6 NM DIAMETER PINHOLE
EYE DEVELOPED WITHIN THE LAST FEW HOURS. CURRENT MAX SUSTAINED WIND
SPEED IS BASED ON SATELLITE INTENSITY FIXES FROM PGTW AND APRF. THE
CYCLONE IS TRACKING ALONG THE PERIPHERY OF A DEEP SUBTROPICAL RIDGE
TO THE SOUTH ALTHOUGH FORWARD MOTION HAS SLOWED DOWN DUE TO ITS
PROXIMITY TO A TROUGH OR WEAKNESS IN THE RIDGE. TC 05S IS EXPECTED TO
INTENSIFY STEADILY UP TO TAU 24 AS IT MOVES OVER WARM WATER AND UNDER
WEAK VERTICAL WIND SHEAR AND STRONG POLEWARD OUTFLOW. AFTER TAU 24,
THE SYSTEM IS EXPECTED TO PASS BY THE TROUGH AND DRIFT TO THE
WEST-NORTHWEST AS THE RIDGE BUILDS AND REALIGNS. THE SYSTEM WILL THEN
BEGIN TO WEAKEN AS THE ENVIRONMENT BECOMES LESS FAVORABLE WITH
INCREASING VERTICAL WIND SHEAR AND COOLER SST. THE MAJORITY OF MODEL

REMARKS:
241500Z POSITION NEAR 17.8S 118.1E.
TROPICAL CYCLONE (TC) 05S (BILLY), LOCATED APPROXIMATELY
360 NM NORTHEAST OF LEARMONTH, AUSTRALIA, HAS TRACKED
WESTWARD AT 08 KNOTS OVER THE PAST SIX HOURS. THE TC
HAS CONTINUED TO RAPIDLY INTENSIFY, WITH THE CURRENT
INTENSITY ESTIMATE SUPPORTED BY SATELLITE INTENSITY
FIXES FROM PGTW AND APRF. ANIMATED INFRARED SATELLITE
IMAGERY CONTINUES TO DEPICT A WELL-DEFINED EYE AND
EXCELLENT POLEWARD OUTFLOW. THE CYCLONE IS TRACKING
ALONG THE PERIPHERY OF A DEEP SUBTROPICAL RIDGE TO THE
SOUTH. TC 05S IS EXPECTED TO MAINTAIN A WEST TO WEST-
NORTHWEST TRACK THROUGH THE DURATION OF THE FORECAST
PERIOD. TC 05S IS EXPECTED TO INTENSIFY SLIGHTLY THROUGH
TAU 12 AS IT CONTINUES TO TRACK OVER WARM WATER AND
REMAINS IN AN AREA OF WEAK VERTICAL WIND SHEAR. AFTER
THIS TIME, THE SYSTEM WILL BEGIN TO WEAKEN AS THE
ENVIRONMENT SLOWLY BECOMES LESS FAVORABLE WITH IN-
CREASING VERTICAL WIND SHEAR AND SLIGHTLY LOWER SEA
SURFACE TEMPERATURES. THE MODEL GUIDANCE REMAINS IN
GOOD AGREEMENT WITH THIS FORECAST SCENARIO. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 241200Z IS 18 FEET. NEXT
WARNINGS AT 250300Z AND 251500Z.

REMARKS:
250300Z POSITION NEAR 17.4S 117.0E.
TROPICAL CYCLONE (TC) 05S (BILLY), LOCATED APPROXIMATELY 335 NM 
NORTHEAST OF LEARMONTH, AUSTRALIA, HAS TRACKED WEST-NORTHWESTWARD AT 
05 KNOTS OVER THE PAST SIX HOURS. INTENSITY HAS SEEN A CYCLIC 
WEAKENING WITH BRIEF INTENSIFICATION OVER THE PAST 12 HOURS. RECENT 
ANIMATED INFRARED IMAGERY HAS SHOWN THAT THE EYE FEATURE HAS SHIFTED 
FROM A RAGGED EYE TO A CLOUD FILLED EYE AND BACK TO A RAGGED SMALL 
EYE. DVORAK INTENSITY FIXES HAVE SHOWN A SLIGHT WEAKENING TREND OVER 
THE PAST 12 HOURS. THE CURRENT INTENSITY IS BASED ON PERSISTENCE, 
AND THE CYCLIC SHIFTS OBSERVED IN THE STRUCTURE OF TC 05S FROM THE 
PREVIOUS FORECAST TO THE CURRENT FORECAST. GOOD UPPER LEVEL OUTFLOW 
FROM THE POLEWARD CHANNEL HAS ALLOWED TC 05S TO MAINTAIN ITS 
INTENSITY OVER THE PAST 12 HOURS, HOWEVER AS TC 05S TRACKS INTO A 
REGION OF UPPER LEVEL CONVERGENCE OUTFLOW WILL BE DIMINISHED. THE 
FORECASTED INTENSITY IS EXPECTED TO CONTINUE TO SLOWLY DECREASE 
THROUGHOUT THE FORECAST PERIOD AS THE SYSTEM CONTINUES TO TRACK 
TOWARDS LESS FAVORABLE ENVIRONMENTS WITH INCREASING VERTICAL WIND 
SHEAR AND DECREASING SEA SURFACE TEMPERATURES. TC 05S CONTINUES TO 
BE STEERED BY MID-LEVEL RIDGING SOUTH OF THE SYSTEM AND IS EXPECTED 
TO MAINTAIN A WEST TO WEST-NORTHWEST TRACK THROUGH THE FORECAST 
PERIOD. MODEL GUIDANCE IS IN GOOD AGREEMENT WITH THE CURRENT TRACK 
THROUGH TAU 36, BUT SHOWS LARGER VARIABILITY IN THE POLEWARD TURN 
BEYOND TAU 36. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 250000Z IS 18 FEET.

REMARKS:
251500Z POSITION NEAR 16.9S 115.5E.
TROPICAL CYCLONE (TC) 05S (BILLY) LOCATED APPROXIMATELY 320 NM NORTH-
NORTHEAST OF LEARMONTH, AUSTRALIA, HAS TRACKED WEST-NORTHWESTWARD AT 
07 KNOTS OVER THE PAST SIX HOURS. TC 05S HAS WEAKENED SLIGHTLY OVER 
THE PAST SIX HOURS FROM A MAXIMUM INTENSITY NEAR 105 KNOTS TO THE 
CURRENT INTENSITY ESTIMATE OF 95 KNOTS, BASED UPON A RANGE OF DVORAK 
ESTIMATES FROM 4.5 (PGTW) TO 6.0 (KNES). THE EYE FEATURE EVIDENT IN 
ANIMATED INFRARED AND MULTISPECTRAL SATELLITE IMAGERY HAS NOW BECOME 
CLOUD FILLED, INDICATING SOME WEAKENING HAS OCCURRED; HOWEVER, TC 
05S HAS UNDERGONE CYCLIC STRENGTHENING AND WEAKENING EPISODES OVER 
THE PAST 36 HOURS, SO SLIGHT NEAR TERM INTENSIFICATION IS POSSIBLE. 
THE SYSTEM CONTINUES TO TRACK TO THE WEST-NORTHWEST ON AN EXTENSION 
OF SUBTROPICAL RIDGE TO THE SOUTHWEST. THE TRACK WILL BECOME MORE 
WESTERLY NEAR TAU 24 AS TROUGHING APPROACHES THE WESTERN COAST OF 
AUSTRALIA. THE SYSTEM IS EXPECTED TO TURN TO A WESTWARD TO WEST-
SOUTHWESTWARD TRACK AFTER TAU 36 AS THE TROUGH DEEPENS. INTENSITY 
WILL SLOWLY WEAKEN AFTER TAU 12 AS THE APPROACHING TROUGH INCREASES 
VERTICAL WINDSHEAR AND THE CONTINUED WESTWARD TRACK BRINGS THE 
SYSTEM OVER LOWER SEA SURFACE TEMPERATURES AND LOWER OCEAN HEAT 
CONTENT. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 251200Z IS 17 FEET. NEXT 
WARNINGS AT 260300Z AND 261500Z.//

REMARKS:
260300Z POSITION NEAR 16.0S 114.4E.
TROPICAL CYCLONE (TC) 05S (BILLY) LOCATED APPROXIMATELY 360 NM NORTH
OF LEARMONTH, AUSTRALIA, HAS TRACKED NORTHWESTWARD AT 06 KNOTS OVER
THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND REC-
ENT MICROWAVE IMAGERY INDICATE THAT THE SYSTEM HAS CONTINUED TO WEAK-
EN WITH DECAY OF DEEP CONVECTION OVER THE NORTHEASTERN QUADRANT.
THERE IS HIGH CONFIDENCE IN THE CURRENT POSITION AND 12-HOUR MOTION
BASED ON A WELL-DEFINED LOW-LEVEL CIRCULATION CENTER (LLCC) IN 36/37
GHZ IMAGERY, PARTICULARLY A 26/0002Z SSMIS IMAGE WHICH SHOWS TIGHTLY
CURVED BANDING (TCB) WRAPPING INTO THE CENTER. THE CURRENT INTENSITY
IS BASED ON THE HIGH SIDE OF DVORAK ESTIMATES RANGING FROM 77 TO 90
KNOTS DUE TO THE TCB AND WELL-DEFINED NATURE OF THE LLCC. TC 05S IS
TRACKING NORTHWESTWARD UNDER THE STEERING INFLUENCE OF THE MID-
LEVEL SUBTROPICAL RIDGE (STR) TO THE SOUTHWEST AND IS EXPECTED TO
CONTINUE TRACKING NORTHWESTWARD TO WEST-NORTHWESTWARD THROUGH TAU 24
ALONG THE NORTHERN PERIPHERY OF THE STR. AFTER TAU 24-36, THE STR IS
FORECAST TO WEAKEN DUE TO AN APPROACHING SHORTWAVE TROUGH AND WILL
TRACK ON A MORE WESTWARD TO WEST-SOUTHWESTWARD TRACK. THE SYSTEM IS
FORECAST TO WEAKEN THROUGH THE PERIOD DUE TO MODERATE VERTICAL
WIND SHEAR, MARGINAL OCEAN HEAT CONTENT AND SST. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 260000Z IS 18 FEET. NEXT WARNINGS AT 261500Z AND
270300Z.//

REMARKS:
261500Z POSITION NEAR 15.2S 113.3E.
TROPICAL CYCLONE (TC) 05S (BILLY) LOCATED APPROXIMATELY 410 NM NORTH
OF LEARMONTH, AUSTRALIA, HAS TRACKED NORTHWESTWARD AT 07 KNOTS OVER
THE PAST SIX HOURS. THE CYCLONE HAS WEAKENED CONSIDERABLY OVER THE
PAST 12 HOURS IN RESPONSE TO HEIGHTENED VERTICAL WINDS SHEAR,
MARGINALLY SUSTAINABLE SEA SURFACE TEMPERATURES AND LESS THAN 
OPTIMAL OCEAN HEAT CONTENT. THE INITIAL FORECAST INTENSITY REFLECTS
A STEADY WEAKENING WITHIN THE CONFINES OF SATELLITE INTENSITY 
ESTIMATES FROM PGTW, APRF, AND KNES RANGING FROM 55 TO 77 KNOTS, 
WHILE THE CURRENT POSITION RELIES HEAVILY ON A 261238Z SSMIS 37 GHZ 
MICROWAVE IMAGE. THE CYCLONE IS FORECAST TO CONTINUE TO WEAKEN WHILE 
TRACKING ALONG THE NORTHEASTERN PERIPHERY OF THE STEERING RIDGE. THE 
STEERING RIDGE WILL THEN REORIENT AS THE RIDGE CENTER MOVES EASTWARD 
TOWARDS PERTH, AUSTRALIA, FORCING THE SYSTEM TO TRACK MORE WEST TO 
SOUTHWESTWARD BEYOND 24 HOURS. THE CYCLONE WILL CONTINUE TO WEAKEN 
THROUGHOUT THE NEXT 2 DAYS DUE TO MODERATE TO HIGH VERTICAL WIND 
SHEAR AND POOR OCEAN HEAT CONTENT, IN ADDITION TO A SLIGHTLY MORE 
STABLE AIRMASS ASSOCIATED WITH AN ADVANCING MID-LATITUDE TROUGH TO 
THE SOUTHWEST.MAXIMUM SIGNIFICANT WAVE HEIGHT AT 261200Z IS 15 FEET.
NEXT WARNINGS AT 270300Z AND 271500Z.

REMARKS:
270300Z POSITION NEAR 15.2S 113.3E.
TROPICAL CYCLONE (TC) 05S (BILLY) LOCATED APPROXIMATELY 420 NM NORTH
OF LEARMONTH, AUSTRALIA, HAS TRACKED NORTHWESTWARD AT 03 KNOTS OVER
THE PAST SIX HOURS. TC 05S HAS CONTINUED TO WEAKEN OVER THE PAST 12
HOURS AS IT TRACKS INTO MODERATE TO HIGH VERTICAL WIND SHEAR.
DIMINISHING SEA SURFACE TEMPERATURES (SST), IN AN ALREADY MARGINAL
ENVIRONMENT, HAVE HELPED TO WEAKEN THE SYSTEM OVER THE PAST 12
HOURS. THE SYSTEM IS TRACKING ON THE NORTHERN PERIPHERY OF A
SUBTROPICAL RIDGE AND AS THE RIDGE SHIFTS FROM OVER THE EASTERN
INDIAN OCEAN TO MOSTLY OVER WESTERN AUSTRALIA, THE TRACK WILL TURN
TO THE SOUTHWEST AND BEGIN TO SPEED UP. TC 05S WILL CONTINUE TO
WEAKEN RAPIDLY AS IT PROGRESSES INTO STRONGER VERTICAL WIND SHEAR
AND COOLER SST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 270000Z IS 15
FEET. NEXT WARNINGS AT 271500Z AND 280300Z.//

REMARKS:
270900Z POSITION NEAR 15.2S 112.8E.
TROPICAL CYCLONE (TC) 05S (BILLY) LOCATED APPROXIMATELY 425 NM NORTH
OF LEARMONTH, AUSTRALIA, HAS TRACKED WESTWARD AT 03 KNOTS OVER THE
PAST SIX HOURS. TC 05S CONTINUES TO STEADILY WEAKEN UNDER THE INFLU-
ENCE OF MODERATE EASTERLY VERTICAL WIND SHEAR. THE SYSTEM IS TRACKING
WESTWARD ALONG THE NORTHERN PERIPHERY OF A SUBTROPICAL RIDGE TO THE
SOUTH. THIS RIDGE IS EXPECTED TO REORIENT OVER THE NEXT FEW DAYS,
INDUCING A SLIGHTLY SOUTH OF WESTWARD TRACK OVER THE NEXT 48 HOURS.
PERSISTENT EASTERLY SHEAR AND PASSAGE ACROSS OCEAN WATER WITH
MARGINAL SURFACE TEMPERATURE WILL CONTINUE THE WEAKENING TREND
THROUGH THE FORECAST PERIOD. MAXIMUM SUSTAINED WIND SPEED IS
EXPECTED TO DROP BELOW THE WARNING THRESHOLD OF 35 KNOTS BY TAU 48.
