SUBJ/TROPICAL CYCLONE FORMATION ALERT 251251Z FEB 01//
RMKS/
1. IMMEDIATE DELIVERY REQ TO AMEMBASSY PORT MORESBY
2. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
175 NM EITHER SIDE OF A LINE FROM 16.4S1 140.8E3 TO 15.8S4
136.0E0 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 20 TO 30 KNOTS.
METSAT IMAGERY AT 251230Z3 INDICATES THAT A CIRCULATION CENTER IS
LOCATED NEAR 16.4S1 140.2E7. THE SYSTEM IS MOVING WEST-
NORTHWESTWARD AT 06 KNOTS.
3. REMARKS: ANIMATED SATELLITE IMAGERY SUGGEST THAT THE TROPICAL
DISTURBANCE WHICH ORIGINATED IN THE CORAL SEA HAS TRACK ACROSS THE
CAPE YORK PENINSULA AND HAS NOW EMERGED IN THE GULF OF CARPENTARIA.
CONVECTION HAS DEEPENED AND BECOME MORE ORGANIZED OVER THE PAST 12
HOURS. UW-CIMSS ANALYSIS PRODUCTS INDICATE THE DISTURBANCE IS IN A
REGION OF WEAK TO MODERATE VERTICAL WIND SHEAR WITH FAIR OUTFLOW
ALOFT. CONVECTION HAS PERSISTED NORTHWEST OF THE LOW LEVEL
CIRCULATION CENTER WHILE THE SYSTEM CONTINUES TO BE SHEARED BY UPPER
LEVEL EASTERLIES. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR
998 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL
CYCLONE WITHIN THE NEXT 24 HOURS IS NOW GOOD.
4. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
261300Z2.//

REMARKS:
252100Z0 POSITION NEAR 16.0S7 139.8E1.
TROPICAL CYCLONE (TC) 12P (ABIGAIL), LOCATED APPROXIMATELY 50 NM
NORTHEAST OF MORNINGTON ISLAND IN THE GULF OF CARPENTARIA, HAS
TRACKED WESTWARD AT 04 KNOTS OVER THE PAST SIX HOURS. THE WARNING
POSITION IS BASED ON 251730Z8 INFRARED SATELLITE IMAGERY AND
SYNOPTIC REPORTS. THE WARNING INTENSITY IS BASED ON CURRENT
INTENSITY ESTIMATES OF 35 KNOTS. ANIMATED SATELLITE IMAGERY
INDICATES TC 12P HAS SLOWED AND INTENSIFIED IN PAST 6 HOURS.
ENHANCED INFRARED SATELLITE IMAGERY DEPICTS BANDS OF DEEP CONVECTION
FORMING IN THE NORTHERN SEMI-CIRCLE. THE 200 MB ANALYSIS INDICATES A
WEAK ANTICYCLONE IS FORMING ABOVE THE LOW LEVEL CIRCULATION CENTER,
AND EASTERLY WINDS ALOFT ARE WEAKENING. TC 12P IS FORECAST TO
TRACK SLOWLY WESTWARD INITIALLY UNDER THE STEERING INFLUENCE OF A
WEAK MID-LEVEL RIDGE TO THE SOUTH. THE SYSTEM SHOULD MOVE MORE
RAPIDLY IN THE LATE PERIOD AS THE MID-LEVEL RIDGE TO THE SOUTH
BUILDS. THE SYSTEM IS EXPECTED TO INTENSIFY RAPIDLY IN THE FIRST 24
HOURS AND THEN MORE SLOWLY THROUGH THE END OF THE FORECAST PERIOD.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 251800Z6 IS 12 FEET. THIS WARNING

TROPICAL CYCLONE (TC) 12P (ABIGAIL), LOCATED NEAR THE NORTHWEST
COAST OF MORNINGTON ISLAND IN THE GULF OF CARPENTARIA, HAS
TRACKED SOUTHWESTWARD AT 05 KNOTS OVER THE PAST SIX HOURS. THE
WARNING POSITION IS BASED ON 260530Z6 INFRARED SATELLITE IMAGERY AND

QUADRANT. THE 200 MB ANALYSIS INDICATES A WEAK ANTICYCLONE IS
FORMING ABOVE THE LOW LEVEL CIRCULATION CENTER, AND EASTERLY WINDS
ALOFT ARE WEAKENING. TC 12P IS FORECAST TO TRACK SLOWLY
SOUTHWESTWARD UNDER THE STEERING INFLUENCE OF A WEAK MID-LEVEL RIDGE
TO THE SOUTH. THE SYSTEM IS EXPECTED TO MAKE LANDFALL JUST NORTHWEST
OF BAYLEY POINT, AUSTRALIA AT AROUND 261400Z3. THE SYSTEM IS

REMARKS:
262100Z1 POSITION NEAR 17.1S9  137.4E5.
TROPICAL CYCLONE (TC) 12P (ABIGAIL), LOCATED ABOUT 25 NM 
NORTH-NORTHWEST OF WOLLOGORANG, AUSTRALIA HAS TRACKED WEST-
SOUTHWESTWARD AT 09 KNOTS DURING THE PAST SIX HOURS. TC 12P MADE 
LANDFALL AT 261400Z3 APPROXIMATELY 35 NM WEST-NORTHWEST OF BAYLEY 
POINT, AUSTRALIA. AT 261700Z6, WOLLOGORANG REPORTED SUSTAINED WINDS 
FROM THE SOUTHEAST AT 35 KNOTS. THE WARNING POSITION IS BASED ON 
261730Z9 INFRARED SATELLITE IMAGERY AND SYNOPTIC REPORTS. THE 
WARNING INTENSITY IS BASED ON CURRENT INTENSITY ESTIMATES OF 55 
KNOTS. ENHANCED INFRARED ANIMATION DEPICTS AN IMPRESSIVE BANDING 
FEATURE WHICH HAS DEVELOPED OVER THE GULF OF CARPENTARIA DURING PAST 
3 HOURS. IMAGERY ALSO INDICATES THAT DEEP CONVECTION STILL REMAINS 
OVER THE SOUTHWEST AND NORTHEAST QUADRANTS OF THE SYSTEM. TC 12P 
(ABIGAIL) SHOULD TRACK GENERALLY WESTWARD WITHIN THE TROPICAL 
EASTERLIES GENERATED BY A LOW/MID-LEVEL RIDGE EXTENDING OVER CENTRAL 
AUSTRALIA. TC 12P IS FORECAST TO WEAKEN AND DISSIPATE BY THE END OF

REMARKS:
270900Z8 POSITION NEAR 17.1S9 135.8E7.
TROPICAL CYCLONE (TC) 12P (ABIGAIL), LOCATED ABOUT 420 NM SOUTHEAST
OF DARWIN, AUSTRALIA, HAS TRACKED WESTWARD AT 08 KNOTS DURING THE
PAST SIX HOURS. THE WARNING POSITION IS BASED ON 270530Z7 VISIBLE
AND INFRARED SATELLITE IMAGERY AND SYNOPTIC REPORTS. THE WARNING
INTENSITY IS BASED ON CURRENT INTENSITY ESTIMATES OF 45 TO 55 KNOTS,
AND SYNOPTIC DATA. ANIMATED VISIBLE AND INFRARED SATELLITE IMAGERY
DEPICT RAPIDLY WEAKENING DEEP CONVECTION OVER THE PAST 6 HOURS.
HOWEVER, IMAGERY SHOWS TIGHTLY-WRAPPED LOW-LEVEL CLOUD LINES.
SYNOPTIC REPORTS ABOUT 60 NM NORTH OF THE SYSTEM (WMO NO. 94248)
INDICATE 27-KNOT SUSTAINED NORTHWESTERLY SURFACE WINDS. TC 12P
(ABIGAIL) SHOULD TRACK GENERALLY WESTWARD WITHIN THE TROPICAL
EASTERLIES GENERATED BY A LOW/MID-LEVEL RIDGE EXTENDING OVER CENTRAL
AUSTRALIA. TC 12P IS FORECAST TO WEAKEN AND DISSIPATE BY THE END OF
THE PERIOD. 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. REFER TO TROPICAL CYCLONE 13P
(PAULA) WARNINGS (WTPS32 PGTW) FOR TWELVE-HOURLY UPDATES.//
