AMPN/REF IS TROPICAL CYCLONE FORMATION ALERT (WTXS21 PGTW 252300)//
RMKS/
SUBJ/TROPICAL CYCLONE FORMATION ALERT 262121Z MAR 06//
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
115 NM EITHER SIDE OF A LINE FROM 15.2S 124.8E TO 16.0S 121.0E
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 30 TO 35 KNOTS. METSAT IM
AGERY AT 261800Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 15.3S 124.5E. THE SYSTEM IS MOVING WEST-SOUTHWESTWARD AT 03
KNOTS.
2. REMARKS: THIS SUPERSEDES REF A. THE AREA OF CONVECTION PREVIOUSLY
LOCATED NEAR 15.2S 124.8E, IS NOW LOCATED NEAR 15.3S 124.5E, APPROX-
IMATELY 210 NM WEST OF WYNDHAM, AUSTRALIA. ANIMATED INFRARED IMAGERY
REVEALS INCREASED DEEP CONVECTION CONTINUING TO WRAP INWARD TOWARD A
WELL-DEVELOPED, COASTAL LOW LEVEL CIRCULATION CENTER (LLCC), WHICH
CONTINUES TO DRIFT SLOWLY WESTWARD. RECENT SATELLITE POSITION ESTI-
MATES PLACE THIS CIRCULATION ON THE IMMEDIATE COAST NEAR KURI BAY.
UPPER LEVEL ANALYSIS INDICATES GOOD RADIAL OUTFLOW AND THE POSSIBLE
FORMATION OF EQUATORWARD AND POLEWARD OUTFLOW CHANNELS. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 30 TO 35 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 998 MB. GIVEN THE IMPROVING
CONVECTIVE SIGNATURE AND PROXIMITY TO THE COAST, THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS REMAINS GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED
BY 272130Z.//

REMARKS:
270300Z POSITION NEAR 15.0S 124.1E.
TROPICAL CYCLONE (TC) 20S (NONAME), LOCATED APPROXIMATELY 80 NM
NORTH-NORTHEAST OF YAMPI SOUND, AUSTRALIA, HAS TRACKED WEST-
SOUTHWESTWARD AT 04 KNOTS OVER THE PAST 06 HOURS. A 270002Z SSMI
PASS CLEARLY DEPICTS AN ORGANIZED LOW LEVEL CIRCULATION CENTER
(LLCC) OVER WATER, AND ANIMATED MULTISPECTRAL IMAGERY REVEALS DEEP
CONVECTION BEGINNING TO ENCIRCLE THE LLCC. THE CYCLONE IS EXPECTED
TO TRACK TOWARD THE WEST-SOUTHWEST ALONG THE NORTHWESTERN PERIPHERY
OF A BUILDING LOW- TO MID-LEVEL RIDGE OVER CENTRAL AUSTRALIA. TC 20s
WILL INTENSIFY STEADILY DUE TO HIGH SEA SURFACE TEMPERATURES AND A
FAVORABLE UPPER LEVEL ENVIRONMENT. THIS WARNING SUPERSEDES AND CANCELS
REF A, NAVPACMETOCCEN 262121Z MAR 06 TROPICAL CYCLONE FORMATION
ALERT (WTXS21 PGTW 262130 ). MAXIMUM SIGNIFICANT WAVE HEIGHT AT 270000Z

280900Z POSITION NEAR 16.1S 120.8E.
TROPICAL CYCLONE (TC) 20S (GLENDA), LOCATED APPROXIMATELY 295 NM
NORTH-NORTHEAST OF PORT HEDLAND, AUSTRALIA, HAS TRACKED WEST-
SOUTHWESTWARD AT 05 KNOTS OVER THE PAST 06 HOURS. TC 20S CONTINUES
TO TRACK ON THE NORTHWEST PERIPHERY OF A STEERING RIDGE OVER
AUSTRALIA. THE SYSTEM HAS RAPIDLY INTENSIFIED AND WILL CONTINUE
TO INTENSIFY OVER THE NEXT 36 HOURS DUE TO SEA SURFACE TEMPERATURES
OF 30 DEGREES CELSIUS OR GREATER AND A VERY FAVORABLE UPPER LEVEL
ENVIRONMENT WITH AN EQUATORWARD AND DEVELOPING POLEWARD OUTFLOW
CHANNELS. BY TAU 48, TC 20S WILL WEAKEN DUE TO INTERACTION WITH
LAND AND INCREASED VERTICAL WIND SHEAR ASSOCIATED WITH AN ADVANCING
MIDLATITUDE TROUGH. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 280600Z IS
35 FEET. NEXT WARNINGS AT 281500Z, 282100Z, 290300Z AND 290900Z.//

REMARKS:
291500Z POSITION NEAR 19.2S 116.9E.
TROPICAL CYCLONE (TC) 20S (GLENDA), LOCATED APPROXIMATELY 125 NM
NORTHWEST OF PORT HEDLAND, AUSTRALIA, HAS TRACKED SOUTHWESTWARD
AT 10 KNOTS OVER THE PAST 06 HOURS. THE TRACK OF TC 20S WILL
CONTINUE TO BECOME MORE POLEWARD AS IT NEARS A WEAKNESS IN THE
MIDLEVEL STEERING RIDGE CAUSED BY A MID-LATITUDE TROUGH OVER THE
WEST COAST OF AUSTRALIA. GRADUAL WEAKENING IS EXPECTED DUE
TO AN INCREASING VERTICAL WIND SHEAR ENVIRONMENT ASSOCIATED
WITH THE SUBTROPICAL JET OVER SOUTHWEST AUSTRALIA. THE SYSTEM
WILL MAKE LANDFALL NEAR TAU 18 AND THEN DISSIPATE OVER LAND.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 291200Z IS 32 FEET. NEXT
WARNINGS AT 292100Z, 300300Z, 300900Z AND 301500Z.//

CENTER INTERACTS WITH LAND. 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.//
