REMARKS:
051500Z1 POSITION NEAR 17.2S0 115.4E1.
TROPICAL CYCLONE (TC) 21S, LOCATED APPROXIMATELY 320 NM NORTH-
NORTHEAST OF LEARMONTH, AUSTRALIA, HAS TRACKED SOUTH-SOUTHEASTWARD
AT 09 KNOTS OVER THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
051130Z0 INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON SATELLITE CURRENT INTENSITY ESTIMATES OF 30 AND 35 KNOTS.
ANIMATED SATELLITE IMAGERY REVEALS THAT THE LOW LEVEL CIRCULATION
CENTER (LLCC) IS SHEARED APPROXIMATELY 50 NM FROM THE REMAINING DEEP
CONVECTION. TC 21S CONTINUES TO ENTRAIN RELATIVELY DRY AIR FROM THE
AUSTRALIAN CONTINENT, WHILE INFLOW REMAINS RESTRICTED BY THE
INDONESIAN ISLANDS NORTH OF THE SYSTEM. TC 21S IS FORECAST TO TRACK
POLEWARD THROUGH THE NEXT 36 HOURS BEFORE ULTIMATELY REVERSING
COURSE TO THE WEST-SOUTHWEST 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, AVN, GFDN, UKMET OFFICE (EGRR),
AND THE AUSTRALIAN GLOBAL AND REGIONAL MODELS ARE IN GOOD AGREEMENT.
OUR FORECAST IS BASED ON A BLEND OF ALL AVAILABLE DYNAMIC AIDS.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 051200Z8 IS 15 FEET. NEXT
WARNINGS AT 052100Z8, 060300Z9, 060900Z5 AND 061500Z2. REFER TO
TROPICAL CYCLONE 23S (KALUNDE) WARNINGS (WTXS31 PGTW) FOR TWELVE-
HOURLY UPDATES. RELEASED BY CAPT KENDALL, USAF.//
