195 NM EITHER SIDE OF A LINE FROM 8.0S8 128.9E0 TO 11.0S2 123.5E1
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
091540Z9 INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 8.5S3
128.0E1. THE SYSTEM IS MOVING WEST-SOUTHWESTWARD AT 06 KNOTS.
3. REMARKS:
THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 8.2S0 130.5E9, IS NOW
LOCATED NEAR 8.7S5 128.8E9, APPROXIMATELY 300 NM NORTHWEST OF DARWIN
IN THE TIMOR SEA. ANIMATED SATELLITE IMAGERY INDICATES INCREASING
DEEP CONVECTION ASSOCIATED WITH A LOW LEVEL CIRCULATION CENTER
(LLCC). THE 200 MB ANALYSIS INDICATES DIFFLUENCE AND WEAK VERTICAL
WIND SHEAR ASSOCIATED WITH THE SUBTROPICAL RIDGE EXTENDING ALONG
12.0S3. MAXIMUM SUSTAINED WINDS ARE ESTIMATED AT 20 TO 25 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE 1004 MB. THE POTENTIAL
FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE
NEXT 24 HOURS IS UPGRADED TO GOOD.

REMARKS:
121500Z9 POSITION NEAR 10.6S7 114.2E8.
TROPICAL CYCLONE (TC) 22S (BONNIE), LOCATED SOUTH OF JAVA, HAS
TRACKED WESTWARD AT 11 KNOTS DURING THE PAST 6 HOURS. THE WARNING
POSITION IS BASED ON 121130Z8 INFRARED SATELLITE IMAGERY AND RECENT
MICROWAVE IMAGERY. THE INTENSITY IS BASED ON SATELLITE CURRENT
INTENSITY ESTIMATES OF 45 AND 55 KNOTS. A 121039Z6 SPECIAL SENSOR
MICROWAVE IMAGE (SSMI) PASS INDICATES THAT THE DEEP CONVECTION LACKS
ORGANIZATION AND IS SHEARED WEST OF THE LOW LEVEL CIRCULATION
HINDERING FURTHER DEVELOPMENT. THE MID-LEVEL RIDGE EXTENDING WESTWARD
OFF OF THE WEST COAST OF AUSTRALIA IS FORECAST TO REMAIN
QUASI-STATIONARY THROUGH THE PERIOD. THEREFORE, TC 22S SHOULD MOVE IN
A WEST-SOUTHWESTWARD DIRECTION OVER THE NEXT 48 HOURS. THE FORECAST
TRACK IS BASED ON A NWP BLEND USING NOGAPS, UK-MET SPECTRAL, NCEP
AVN, TLAPS, AND GFDN. TC 22S SHOULD INTENSIFY AT A LESS THAN
CLIMATOLOGICAL RATE AS IT REMAINS NORTH OF THE UPPER LEVEL RIDGE AXIS
AND ENCOUNTERS EASTERLY VERTICAL WIND SHEAR THROUGH THE PERIOD.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 121200Z6 IS 15 FEET. NEXT WARNINGS
AT 130300Z7 AND 131500Z0.//

REMARKS:
141500Z1 POSITION NEAR 14.0S5 104.7E2.
TROPICAL CYCLONE (TC) 22S (BONNIE), LOCATED APPROXIMATELY 300 NM
SOUTH-SOUTHEAST OF THE COCOS ISLANDS, HAS TRACKED SOUTHWESTWARD AT
11 KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
EXTRAPOLATION. THE INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY
ESTIMATES OF 35 KNOTS AND A 141036Z5 QUIKSCAT PASS. ANIMATED
INFRARED IMAGERY INDICATES THAT MOST OF THE DEEP CONVECTION HAS
DISSIPATED. TC 22S IS EQUATORWARD OF THE RIDGE AXIS AND REMAINS
UNDER THE STEERING INFLUENCE OF THE LOW TO MID-LEVEL RIDGE CENTERED
NEAR NORTHWEST CAPE, AUSTRALIA. THE SYSTEM IS FORECAST TO CONTINUE
TRACKING TO THE WEST-SOUTHWEST OVER THE NEXT 48 HOURS TOWARDS A
WEAKNESS IN THE MID-LEVEL RIDGE. TC 22S IS FORECAST TO MAINTAIN
INTENSITY AS IT TRAVELS UNDER THE RIDGE AXIS IN A FAVORABLE
ENVIRONMENT. AN APPROACHING LONG WAVE TROUGH SHOULD ENHANCE THE
OUTFLOW TO INSTIGATE CONVECTION. THE FORECAST TRACK IS BASED ON A
BLEND OF ALL THE DYNAMIC AIDS INCLUDING NOGAPS, UK-MET SPECTRAL,
NCEP AVIATION, GFDN, AND BUREAU OF METEOROLOGY TLAPS AND TCLAPS
MODELS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 141200Z8 IS 15 FEET.
NEXT WARNINGS AT 150300Z9 AND 151500Z2.//

150300Z9 POSITION NEAR 15.8S4 101.1E3.
TROPICAL CYCLONE (TC) 22S (BONNIE), LOCATED APPROXIMATELY 340 NM
SOUTHEAST OF THE COCOS ISLANDS, HAS TRACKED WEST-SOUTHWESTWARD AT 16
KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
142330Z3 INFRARED SATELLITE IMAGERY AND A 142302Z2 SSM/I PASS. THE
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 30 AND
35 KNOTS. ANIMATED INFRARED IMAGERY INDICATES CONVECTION HAS
INCREASED OVER THE PAST 6 HOURS, BUT REMAINS DISORGANIZED. RECENT
MULTI-SPECTRAL IMAGERY DEPICTS THAT THE CONVECTION IS SHEARED TO THE
SOUTH OF THE LOW LEVEL CIRCULATION CENTER. TC 22S REMAINS UNDER THE
STEERING INFLUENCE OF THE LOW TO MID-LEVEL RIDGE ANCHORED NEAR NORTH
WEST CAPE, AUSTRALIA. THE SYSTEM IS FORECAST TO CONTINUE TRACKING
WEST-SOUTHWESTWARD AND WEAKEN SLOWLY OVER THE NEXT 48 HOURS AS IT
ENCOUNTERS INCREASING VERTICAL WIND SHEAR. THE FORECAST TRACK IS
BASED ON A BLEND OF ALL THE DYNAMIC AIDS INCLUDING NOGAPS, UK-MET
SPECTRAL, NCEP AVIATION, AND GFDN. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
150000Z6 IS 12 FEET. NEXT WARNINGS AT 151500Z2 AND 160300Z0.//

151500Z2 POSITION NEAR 16.2S9 97.6E2.
TROPICAL CYCLONE (TC) 22S (BONNIE), LOCATED APPROXIMATELY 250 NM
SOUTH-SOUTHEAST OF THE COCOS ISLANDS, HAS TRACKED WESTWARD AT 16
KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON A
151138Z9 SSM/I PASS. THE INTENSITY IS BASED ON EXTRAPOLATION OF
RECENT SATELLITE INTENSITY ESTIMATES OF 30 AND 35 KNOTS. ANIMATED
INFRARED IMAGERY INDICATES CONVECTION HAS DISSIPATED NEAR THE LOW-
LEVEL CIRCULATION CENTER (LLCC) AND ONLY SCATTERED DEEP CONVECTION
TO THE NORTHWEST REMAINS. MULTI-SPECTRAL IMAGERY DEPICTS A RAPIDLY
WEAKENING LLCC. TC 22S SHOULD TRACK TO THE WEST AND DISSIPATE UNDER
THE STEERING INFLUENCE OF AN APPROACHING LOW TO MID-LEVEL RIDGE TO
THE SOUTHWEST. THE FORECAST TRACK IS BASED ON A BLEND OF NOGAPS,
GFDN, AND THE SHALLOW BETA ADVECTION MODEL. MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 151200Z IS 12 FEET. THIS IS THE FINAL WARNING ON THIS
SYSTEM BY THE JOINT TYPHOON WARNING CENTER (NAVPACMETOCCEN). THE
SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION.//
