RMKS/
1. IMMEDIATE DELIVERY REQ TO AMEMBASSY SUVA
2. AMEMBASSY SUVA REQ PASS TO USAID OFDA ADVISOR
3. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
150 NM EITHER SIDE OF A LINE FROM 9.3S2 178.3W9 TO 14.9S4 179.9W6
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. METSAT
IMAGERY AT 110530Z0 INDICATES THAT A CIRCULATION CENTER IS
LOCATED NEAR 10.3S4 178.8W4. THE SYSTEM IS MOVING SOUTHWARD AT
10 KNOTS.
4. REMARKS:
ANIMATED SATELLITE IMAGERY INDICATES INCREASING ORGANIZATION OVER
THE PAST 12 HOURS. RECENT MICROWAVE IMAGERY INDICATES MODERATE
CONVECTION IN A BAND SOUTH OF THE LOW LEVEL CIRCULATION CENTER
(LLCC). THE SYSTEM REMAINS IN A REGION OF WEAK TO MODERATE VERTICAL
WIND SHEAR,
WITH INCREASING VERTICAL WIND SHEAR TO THE SOUTH. OUTFLOW ALOFT
REMAINS GOOD. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE 1000 MB.
THE POTENTIAL FOR DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS GOOD.
5. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
120921Z5.//

REMARKS:
112100Z5 POSITION NEAR 11.5S7 179.2W9.
TROPICAL CYCLONE (TC) 10P, LOCATED APPROXIMATELY 300 NM NORTH OF
THE FIJI ISLANDS, HAS TRACKED SOUTHWARD AT 05 KNOTS DURING THE PAST
SIX HOURS. THE WARNING POSITION IS BASED ON 111730Z3 ENHANCED
INFRARED AND RECENT MICROWAVE SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 35
KNOTS. ANIMATED SATELLITE IMAGERY INDICATES THE DEEP CONVECTION
REMAINS CYCLIC, HOWEVER, CENTRAL CONVECTION HAS INCREASED AND BECOME
MORE ORGANIZED OVER THE LOW-LEVEL CIRCULATION CENTER (LLCC) DURING
THE PAST 12 HOURS. UPPER-LEVEL ANALYSIS REVEALS FAVORABLE DIFFLUENCE
ALOFT AND VERTICAL WIND SHEAR OVER THE SYSTEM IS LOW TO MODERATE. TC
10P IS FORECAST TO INTENSIFY AT A SLIGHTLY LESS THAN CLIMATOLOGICAL
RATE AS THE SYSTEM TRACKS TOWARDS AN AREA OF INCREASED VERTICAL WIND
SHEAR. AVAILABLE DYNAMIC AIDS CONSISTING OF NGPS, NCEP AVIATION
(AVN), UK MET OFFICE (EGRR), NOGAPS AND BETA ADVECTION MODELS ARE IN
GOOD AGREEMENT WITH THIS SCENARIO. THIS FORECAST IS BASED ON
PERSISTENCE AND A CONSENSUS OF THE AVAILABLE DYNAMIC AIDS. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 111800Z1 IS 12 FEET. REFER TO WWPN31 PHNC
FOR ADDITIONAL SEA HEIGHT INFORMATION. THIS WARNING SUPERSEDES AND

LOCATED APPROXIMATELY 400 NM NORTH OF SUVA, FIJI HAS TRACKED
SOUTHWESTWARD AT 06 KNOTS DURING THE PAST SIX HOURS. THE WARNING
POSITION IS BASED ON 120530Z1 ANIMATED SATELLITE IMAGERY. THE
WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES
OF 55 KNOTS. ANIMATED SATELLITE IMAGERY INDICATES INCREASED
ORGANIZATION OVER THE PAST 6 HOURS, WITH A BANDING FEATURE WRAPPING
INTO THE SOUTH OF THE LOW-LEVEL CIRCULATION CENTER (LLCC). UPPER-
LEVEL ANALYSIS REVEALS FAVORABLE DIFFLUENCE ALOFT AND VERTICAL WIND
SHEAR OVER THE SYSTEM IS LOW TO MODERATE. TC 10P IS FORECAST TO
INTENSIFY OVER THE NEXT 12-24 HOURS, BEFORE MOVING INTO AN AREA OF
INCREASED VERTICAL WIND SHEAR AND WEAKENING THROUGH THE REMAINDER OF
THE PERIOD. THE SYSTEM IS EXPECTED TO BEGIN UNDERGOING EXTRATROPICAL
TRANSITION AROUND THE 48 HOUR PERIOD, AS IT MOVES INTO THE MID-
LATITUDE WESTERLIES. AVAILABLE DYNAMIC AIDS INCLUDING NOGAPS, NCEP,
UK MET OFFICE, AND THE BETA ADVECTION MODELS ARE IN GOOD AGREEMENT

TROPICAL CYCLONE (TC) 10P (AMI), LOCATED APPROXIMATELY 85 NM
NORTHEAST OF SUVA, FIJI HAS TRACKED SOUTHWARD AT 12 KNOTS DURING THE
PAST SIX HOURS. THE WARNING POSITION IS BASED ON 131730Z5 ENHANCED
INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
SATELLITE CURRENT INTENSITY ESTIMATES OF 90 KNOTS. ANIMATED WATER
VAPOR IMAGERY INDICATES GOOD POLEWARD OUTFLOW, BEING ENHANCED BY A
DEEPENING UPPER LEVEL TROUGH TO THE SOUTHWEST. TC 10P IS FORECAST TO
TRACK SOUTHEASTWARD THROUGH THE PERIOD ALONG THE SUBTROPICAL RIDGE
TO THE EAST OF THE SYSTEM. SYSTEM INTENSITY IS EXPECTED TO REMAIN
STEADY OVER THE NEXT 12 HOURS, THEN WEAKEN AS IT TRACKS POLEWARD OF
THE UPPER LEVEL RIDGE AXIS AND ENCOUNTERS INCREASING VERTICAL WIND
SHEAR. THE SYSTEM IS EXPECTED TO BEGIN UNDERGOING EXTRATROPICAL
TRANSITION IN 12 TO 24 HOURS AS IT INTERACTS WITH A DEVELOPING MID-
LATITUDE LOW NEAR NEW ZEALAND. THE AVAILABLE DYNAMIC AIDS INCLUDING
NOGAPS, GFDN, NCEP AVIATION (AVN), UKMET GLOBAL (EGRR), AND THE BETA

REMARKS:
140300Z8 POSITION NEAR 20.1S3 178.3W9.
THE 131800Z3 WARNING HAS BEEN AMENDED BASED ON RAPID INTENSIFICATION
AND INCREASE IN SPEED OVER THE PAST SIX HOURS BASED ON VISIBLE AND
WATER VAPOR SATELLITE IMAGERY. TROPICAL CYCLONE (TC) 10P (AMI),
LOCATED APPROXIMATELY 168 NM EAST-NORTHEAST OF SUVA, FIJI HAS TRACKED
SOUTH-SOUTHEASTWARD AT 24 KNOTS DURING THE PAST SIX HOURS. THE
WARNING POSITION IS BASED ON 132330Z2 ENHANCED INFRARED AND VISIBLE
SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE
CURRENT INTENSITY ESTIMATES OF 102 AND 115 KNOTS. ANIMATED WATER
VAPOR IMAGERY INDICATES THE UPPER LEVEL TROUGH TO THE SOUTHWEST HAS
VENTILATED THE SYSTEM MORE THAN EXPECTED, INCREASING POLEWARD
OUTFLOW. VISIBLE IMAGERY DEPICTS A 29 NM IRREGULAR EYE HAS FORMED.
TC 10P IS FORECAST TO TRACK SOUTHEASTWARD THROUGH THE PERIOD ALONG
THE SUBTROPICAL RIDGE TO THE EAST OF THE SYSTEM. SYSTEM INTENSITY IS
EXPECTED TO REMAIN STEADY OVER THE NEXT 6 TO 12 HOURS, THEN WEAKEN
AS IT TRACKS POLEWARD OF THE UPPER LEVEL RIDGE AXIS AND ENCOUNTERS
INCREASING VERTICAL WIND SHEAR. THE SYSTEM IS EXPECTED TO BEGIN
UNDERGOING EXTRATROPICAL TRANSITION IN 12 TO 24 HOURS AS IT
INTERACTS WITH A DEVELOPING MID-LATITUDE LOW NEAR NEW ZEALAND. THE
AVAILABLE DYNAMIC AIDS INCLUDING NOGAPS, GFDN, NCEP AVIATION (AVN),
UKMET GLOBAL (EGRR), AND THE BETA ADVECTION MODELS ARE IN GOOD
AGREEMENT WITH THIS SCENARIO. THIS FORECAST IS BASED ON PERSISTENCE
AND A CONSENSUS OF THE AVAILABLE DYNAMIC AIDS. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 140000Z5 IS 16 FEET. NEXT WARNINGS AT 140900Z4 AND
142100Z8.//
