Tropical Cyclone FRITZ : JTWC Advisories
Season 2003-2004 Summaries (Operational Data): [AU] [SIO] [SPAC] [SH]
---> Tropical Cyclone FRITZ Track Map and Data

WTPS21 PGTW 20040210 17:00z
IMMEDIATE DELIVERY REQ TO AMEMBASSY PORT MORESBY
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
115 NM EITHER SIDE OF A LINE FROM 13.5S9 146.2E3 TO 14.4S9
142.7E4 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 25 TO 30 KNOTS. MET
SAT IMAGERY AT 101521Z0 INDICATES THAT A CIRCULATION CENTER IS
LOCATED NEAR 13.7S1 145.6E6. THE SYSTEM IS MOVING WEST-SOUTH
WESTWARD AT 21 KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 13.1S5
147.1E3 IS NOW LOCATED NEAR 13.7S1 145.6E6, APPROXIMATELY 110 NM
EAST-NORTHEAST OF PORT STEWART, AUSTRALIA. ANIMATED INFRARED
SATELLITE IMAGERY INDICATES INCREASED SPIRAL BANDING AND A RAPID
INCREASE IN CONVECTION OVER THE PAST 12 HOURS. UPPER LEVEL ANALYSIS
REVEALS MODERATE DIFFLUENCE AND WEAK TO MODERATE VERTICAL WIND
SHEAR OVER THE AREA. DUE TO THE IMPROVING CONDITIONS, THE POTENTIAL
FOR THE 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 111700Z0.//
4. RELEASED BY: LCDR ARENDS, USN.

REMARKS:
120300Z6 POSITION NEAR 16.8S5 139.8E1.
TROPICAL CYCLONE (TC) 12P (FRITZ), LOCATED APPROXIMATELY 45 NM
EAST OF MORNINGTON ISLAND, IN THE GULF OF CARPENTARIA, HAS
MOVED WEST-SOUTHWESTWARD AT 06 KNOTS OVER THE PREVIOUS SIX HOURS.
THE WARNING POSITION IS BASED ON 112330Z0 VISIBLE SATELLITE
IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT
INTENSITY ESTIMATES OF 35 AND 45 KNOTS. RECENT RADAR IMAGERY
FROM MORNINGTON ISLAND INDICATES THE PRESENCE OF A GOOD LOW
LEVEL CIRCULATION CENTER. ALTHOUGH CURRENT SYNOPTIC WIND REPORTS
ARE LOWER THAN THE SATELLITE BASED INTENSITY ESTIMATES, THE UPPER
LEVEL ENVIRONMENT FOR OUTFLOW IS GOOD AND SHEAR IS MINIMAL. TC 12P
HAS TIME AND THE ENVIRONMENT TO DEVELOP FURTHER BEFORE LANDFALL.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 120000Z3 IS 12 FEET. NEXT
WARNING AT 121500Z9.//
