REMARKS:
070900Z6 POSITION NEAR 19.3S3 114.1E7.
TROPICAL CYCLONE (TC) 21S (HARRIET), LOCATED APPROXIMATELY 180 NM
NORTH OF LEARMONTH, AUSTRALIA, HAS DRIFTED WESTWARD AT 02 KNOTS OVER
THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 070530Z5 VISIBLE
AND ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS
BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 30 AND 35 KNOTS.
ANIMATED VISIBLE IMAGERY INDICATES THAT THE SYSTEM HAS REMAINED
QUASI-STATIONARY OVER THE PAST 12 TO 18 HOURS. TC 21S IS FORECAST TO
TRACK SOUTHWESTWARD THROUGH 36 TO 48 HOURS AND THEN SOUTHWARD 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 36 HOURS, THEN WEAKEN DUE TO AN
INCREASED VERTICAL WIND SHEAR AND COOLER SEA SURFACE TEMPERATURES.
THE AVAILABLE DYNAMIC AIDS, CONSISTING OF NOGAPS, AVN, 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 070600Z3 IS 15 FEET. NEXT WARNINGS AT 071500Z3,
072100Z0, 080300Z1 AND 080900Z7. REFER TO TROPICAL CYCLONE 23S
(KALUNDE) WARNINGS (WTXS31 PGTW) FOR TWELVE-HOURLY UPDATES. RELEASED
