WTPS23 PGTW 20020102 08:00z
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
115 NM EITHER SIDE OF A LINE FROM 14.7S2 139.1E4 TO 16.2S9
137.7E8 WITHIN THE NEXT 12 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 25 TO 30 KNOTS. METSAT
IMAGERY AT 020530Z0 INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 14.9S4 139.0E3. THE SYSTEM IS MOVING SOUTHWARD AT 03 KNOTS.
2. REMARKS:
THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 15.3S9 138.5E7 IS NOW
LOCATED NEAR 14.9S4 139.0E3 OVER THE GULF OF CARPENTARIA. ANIMATION
DEPICTS CONVECTION CONTINUES TO ORGANIZE OVER THE PAST 6 HOURS.
SYNOPTIC DATA AND THE RADAR LOOP FROM GOVE, AUSTRALIA INDICATE A
BROAD LOW-LEVEL CIRCULATION CENTER. MAXIMUM SUSTAINED SURFACE WINDS
ARE ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED AT 999 MB. THE POTENTIAL FOR DEVELOPMENT OF A SIGNIFICANT
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
030800Z1.//

REMARKS:
030900Z2 POSITION NEAR 14.3S8 138.8E0.
TROPICAL CYCLONE (TC) 09P (BERNIE) HAS DEVELOPED IN THE GULF OF
CARPENTARIA. TC 09P HAS TRACKED SOUTH-SOUTHWESTWARD AT 03 KNOTS
DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 030530Z1
VISIBLE AND INFERRED SATELLITE IMAGERY. THE WARNING INTENSITY IS
BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 30 KNOTS. ANIMATED
SATELLITE IMAGERY REVEALS CONVECTION BEING SHEARED TO THE SOUTHWEST
OF THE LOW LEVEL CIRCULATION CENTER. THE MID-LEVEL SUBTROPICAL RIDGE
JUST EAST OF TC 09P, AS WELL AS A 700 MB RIDGE CENTERED AROUND 22S4
AND 132E6, WILL TRACK THE SYSTEM TO THE SOUTHWEST THROUGH THE
FORECAST PERIOD. THE AVAILABLE DYNAMIC AIDS OF NOGAPS AND THE BETA
ADVECTION MODELS AGREE WITH THIS SCENARIO. 200 MB ANALYSIS INDICATES
THE SYSTEM IS IN A WEAK TO MODERATE VERTICAL WIND SHEAR ENVIRONMENT
WITH GOOD OUTFLOW ALOFT. THE SYSTEM IS FORECAST TO INTENSIFY AT A
NEAR CLIMATOLOGICAL RATE THROUGH THE PERIOD AS IT REMAINS IN A
FAVORABLE ENVIRONMENT. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 030600Z9
IS 08 FEET. THIS WARNING SUPERSEDES AND CANCELS REF A,

SOUTHWESTWARD AT 06 KNOTS DURING THE PAST 6 HOURS. THE WARNING
POSITION IS BASED ON 031730Z4 INFRARED SATELLITE IMAGERY, RADAR, AND

CURRENT INTENSITY ESTIMATES OF 45 TO 55 KNOTS, AND A BUOY REPORT
(52627) OF 43 KNOTS NEAR THE CENTER AT 031400Z8. ANIMATED SATELLITE
IMAGERY REVEALS CONVECTION CONTINUES TO BE SHEARED TO THE SOUTHWEST
OF THE LOW LEVEL CIRCULATION CENTER. THE MID-LEVEL SUBTROPICAL RIDGE
EAST OF TC 09P WILL CONTINUE TO TRACK THE SYSTEM TO THE SOUTH-
SOUTHWEST THROUGH THE FORECAST PERIOD. THE AVAILABLE DYNAMIC AIDS
(NGPS, AVN, EGRR, TLAPS, TCLPS) AGREE WITH THIS SCENARIO. 200 MB
ANALYSIS INDICATES THE SYSTEM IS NORTH OF THE UPPER LEVEL RIDGE AXIS
IN A WEAK TO MODERATE VERTICAL WIND SHEAR ENVIRONMENT WITH GOOD
