REMARKS:
020900Z1 POSITION NEAR 14.2S7 107.1E9.
TROPICAL CYCLONE (TC) 21S, LOCATED APPROXIMATELY 640 NM NORTHWEST OF
LEARMONTH, AUSTRALIA, HAS TRACKED EAST-SOUTHEASTWARD AT 10 KNOTS
OVER THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 020530Z0
VISIBLE AND ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 30
KNOTS AND A 020006Z8 TRMM PASS. ANIMATED SATELLITE IMAGERY AND
RECENT MICROWAVE DATA INDICATE IMPROVED ORGANIZATION OVER THE PAST 6
HOURS. TC 21S IS EXPECTED TO CONTINUE TRACKING EAST-SOUTHEASTWARD
OVER THE NEXT 24 HOURS UNDER THE STEERING INFLUENCE OF A LOW TO MID-
LEVEL NEAR-EQUATORIAL RIDGE TO THE NORTH. THE SYSTEM IS EXPECTED TO
INTENSIFY SLOWLY THROUGH 24 TO 36 HOURS WHILE IN A MODERATELY
FAVORABLE UPPER LEVEL ENVIRONMENT. THE DYNAMIC AIDS CONSIST OF UKMET
(EGRR) AND NOGAPS. UKMET TRACKED THE SYSTEM FASTER WITHIN THE
MONSOON TROUGH. THE FORECAST IS BASED ON A BLEND OF EGRR, NOGAPS,
AND THE MEDIUM BETA ADVECTION MODEL. MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 020600Z8 IS 15 FEET. THIS WARNING SUPERSEDES AND CANCELS REF A,

REMARKS:
022100Z5 POSITION NEAR 15.0S6 108.7E6.
TROPICAL CYCLONE (TC) 21S, LOCATED APPROXIMATELY 540 NM NORTHWEST OF
LEARMONTH, AUSTRALIA, HAS TRACKED EAST-SOUTHEASTWARD AT 09 KNOTS
OVER THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 021730Z3
ENHANCED INFRARED SATELLITE IMAGERY AND A 021421Z0 SSM/I PASS. THE
WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES
OF 30 KNOTS AND THE SSM/I PASS. MIROWAVE IMAGERY CONTINUES TO SHOW A
GOOD CIRCULATION, HOWEVER ANIMATED SATELLITE IMAGERY INDICATES THE
DEEP CONVECTION HAS WEAKENED OVER THE LAST 6 HOURS. TC 21S IS
EXPECTED TO CONTINUE TRACKING EAST-SOUTHEASTWARD OVER THE FORECAST
PERIOD UNDER THE STEERING INFLUENCE OF A LOW TO MID-LEVEL NEAR
EQUATORIAL RIDGE TO THE NORTH. THE SYSTEM WILL REMAIN WEAK DUE TO
POOR UPPER LEVEL OUTFLOW CONDITIONS THROUGH 24 HOURS, ATERWARDS, TC
21S IS EXPECTED TO INTENSIFY SLIGHTLY AS THE OUTFLOW CONDITIONS
IMPROVE. THE DYNAMIC AIDS CONSIST OF UKMET (EGRR) AND NOGAPS. THE
FORECAST IS BASED ON A BLEND OF EGRR AND NOGAPS. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 021800Z1 IS 15 FEET. NEXT WARNINGS ARE AT 030900Z2
AND 032100Z6. REFER TO TROPICAL CYCLONE 19S (JAPHET) WARNINGS

TROPICAL CYCLONE (TC) 21S, LOCATED APPROXIMATELY 470 NM NORTH-
NORTHWEST OF LEARMONTH, AUSTRALIA, HAS TRACKED EASTWARD AT 06 KNOTS
OVER THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 031730Z4
ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON SATELLITE CURRENT INTENSITY ESTIMATES OF 30 KNOTS. ANIMATED
INFRARED SATELLITE IMAGERY REVEALS TC 21S TO BE A SMALL, RELATIVELY
SYMMETRIC SYSTEM. TC 21S HAS MAINTAINED INTENSITY AT A STEADY STATE
OVER THE PAST 12 TO 24 HOURS, WITH THE LOW LEVEL CIRCULATION CENTER
(LLCC) HIDDEN UNDER THE CENTRAL DENSE OVERCAST (CDO). RECENT SPECIAL
SENSOR MICROWAVE IMAGER (SSM/I) PASSES INDICATE THAT TC 21S IS BEING
HAMPERED IN FURTHER DEVELOPMENT BY THE ENTRAINMENT OF RELATIVELY DRY
AIR FROM THE SOUTHWEST, AND EQUATORWARD OUTFLOW IS BEING RESTRICTED
BY THE NUMEROUS ISLANDS THAT COMPRISE INDONESIA TO THE NORTH. TC 21S
IS EXPECTED TO CONTINUE TRACKING EAST-SOUTHEASTWARD THROUGH THE NEXT
24 TO 36 HOURS UNDER THE STEERING INFLUENCE OF A LOW TO MID-LEVEL
NEAR EQUATORIAL RIDGE TO THE NORTH, THEN MORE POLEWARD THEREAFTER IN
RESPONSE TO INTERACTION WITH A DEVELOPING WEAK LOW TO THE SOUTHWEST.
THE DYNAMIC AIDS, CONSISTING OF NOGAPS, GFDN, AND UK MET OFFICE
(EGRR) ARE IN AGREEMENT, WITH THE NCEP AVIATION MODEL (AVN) THE LONE
OUTLIER ACCELERATING 19S TO THE NORTHEAST. THIS FORECAST IS BASED ON

FURTHER DEVELOPMENT BY THE ENTRAINMENT OF RELATIVELY DRY AIR FROM
THE SOUTHWEST, AND EQUATORWARD OUTFLOW IS RESTRICTED BY THE NUMEROUS
ISLANDS THAT COMPRISE INDONESIA TO THE NORTH. TC 21S IS EXPECTED TO
CONTINUE TRACKING EAST-SOUTHEASTWARD THROUGH THE NEXT 24 HOURS UNDER
THE STEERING INFLUENCE OF A MID-LEVEL NEAR EQUATORIAL RIDGE TO THE
NORTH, THEN MORE POLEWARD THROUGH THE FORECAST PERIOD IN RESPONSE TO
A WEAKNESS IN THE SUBTROPICAL RIDGE SOUTH OF SYSTEM. TC 21S IS
EXPECTED TO INTENSIFY SLOWLY IN A MARGINAL UPPER LEVEL ENVIRONMENT.
THE DYNAMIC AIDS, CONSISTING OF NOGAPS, GFDN, AND UKMET OFFICE
(EGRR) ARE IN GOOD AGREEMENT WITH THE NCEP AVIATION MODEL AS THE
OUTLIER HOLDING TC 21S TO AN EASTERLY TRACK. THIS FORECAST IS BASED

052100Z8 POSITION NEAR 17.5S3 116.0E8.
TROPICAL CYCLONE (TC) 21S (HARRIET), LOCATED APPROXIMATELY 300 NM
NORTH-NORTHEAST OF LEARMONTH, AUSTRALIA, HAS TRACKED SOUTHEAST AT 06
KNOTS OVER THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
051730Z6 INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON SATELLITE CURRENT INTENSITY ESTIMATES OF 30 AND 35 KNOTS.
ANIMATED SATELLITE IMAGERY INDICATES THAT CONVECTION ASSOCIATED WITH
THE LOW LEVEL CIRCULATION CENTER (LLCC) HAS RE-INTENSIFIED DURING
THE PAST 06 HOURS. TC 21S IS FORECAST TO SLOWLY TURN TO THE
SOUTHWEST DURING THE NEXT 12 TO 24 HOURS AND MOVE INTO A WEAKNESS IN
THE SUBTROPICAL RIDGE. TC 21S SHOULD INTENSIFY GRADUALLY AS THE
UPPER LEVEL ENVIRONMENT IMPROVES THROUGH THE FORECAST PERIOD. THE
AVAILABLE DYNAMIC AIDS, CONSISTING OF NOGAPS, GFDN, UKMET OFFICE
(EGRR), AND THE AUSTRALIAN GLOBAL AND REGIONAL MODELS ARE IN GOOD
AGREEMENT WITH AVN AN OUTLIER TURNING TC 21S SHARPLY WEST. OUR
FORECAST IS BASED ON A BLEND OF AVAILABLE DYNAMIC AIDS MINUS AVN.

TROPICAL CYCLONE (TC) 21S (HARRIET), LOCATED APPROXIMATELY 175 NM
NORTH OF LEARMONTH, AUSTRALIA, HAS TRACKED WEST-SOUTHWESTWARD AT 03
KNOTS OVER THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
062330Z4 VISIBLE AND ENHANCED INFRARED SATELLITE IMAGERY. THE
WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES
OF 30 AND 35 KNOTS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY
INDICATES CYCLING CONVECTION OVER THE PAST 6 HOURS. TC 21S IS
FORECAST TO TRACK SOUTHWESTWARD THROUGH 72 HOURS INTO A WEAKNESS IN
THE LOW TO MID-LEVEL SUBTROPICAL RIDGE SOUTHEAST OF THE SYSTEM. TC
21S IS EXPECTED TO SLOWLY INTENSIFY AS THE UPPER LEVEL ENVIRONMENT
IMPROVES OVER THE NEXT 48 HOURS. AFTER THE 48 HOUR POINT, INTENSITY
IS EXPECTED TO DECREASE DUE TO AN INCREASED VERTICAL WIND SHEAR
ENVIRONMENT AND COOLER SEA SURFACE TEMPERATURES. THE AVAILABLE
DYNAMIC AIDS, CONSISTING OF NOGAPS, AVN, GFDN, UKMET OFFICE (EGRR),
TLAPS, AND TCLAPS, ARE IN FAIR AGREEMENT. OUR FORECAST IS BASED ON A
BLEND OF ALL AVAILABLE DYNAMIC AIDS. MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 062330Z4 IS 15 FEET. NEXT WARNINGS AT 070900Z6 AND 071500Z3.

REMARKS:
090300Z2 POSITION NEAR 21.3S6 110.7E9.
TROPICAL CYCLONE (TC) 21S (HARRIET), LOCATED APPROXIMATELY 295 NM
WEST-NORTHWEST OF LEARMONTH, AUSTRALIA, HAS TRACKED SOUTHWESTWARD AT
08 KNOTS OVER THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
082330Z6 ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY
IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 25 KNOTS.
ANIMATED INFRARED AND WATER VAPOR SATELLITE IMAGERY SHOW SOME WEAK
CONVECTION OVER THE LOW LEVEL CIRCULATION CENTER, BUT THE SYSTEM IS
STILL VERY SMALL IN AREAL SIZE. TC 21S IS FORECAST TO CONTINUE
TRACKING SOUTHWESTWARD, THEN SOUTH, PARALLEL TO THE AUSTRALIA COAST
IN RESPONSE TO A MID-LATITUDE UPPER-LEVEL TROUGH APPROACHING
SOUTHWEST AUSTRALIA FROM THE INDIAN OCEAN. THE COMBINED EFFECTS OF
SHEAR, AS THE SYSTEM TRACKS SOUTH, AND COOLER SEA SURFACE
TEMPERATURES (SST) ARE EXPECTED TO WEAKEN TC 21S SIGNIFICANTLY OVER
WATER AS THE REMNANTS CONTINUE SOUTHWARD. THE AVAILABLE DYNAMIC
AIDS, CONSISTING OF NOGAPS, GFDN, UKMET OFFICE (EGRR), NCEP
AVIATION, AND THE AUSTRALIA BOM MODELS (TLAPS AND TCLAPS) ARE IN
CLOSE AGREEMENT. THIS FORECAST IS BASED ON A CONSENSUS OF THE
AVAILABLE AIDS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 090000Z9 IS 11
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. REFER TO TROPICAL CYCLONE 23S
(KALUNDE) WARNINGS (WTXS31 PGTW) FOR TWELVE-HOURLY UPDATES. REFER TO
TROPICAL CYCLONE 24S WARNINGS (WTXS33 PGTW) FOR TWELVE-HOURLY
UPDATES.
