SUBJ/TROPICAL CYCLONE FORMATION ALERT//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
125 NM EITHER SIDE OF A LINE FROM 15.1S 177.7E TO 19.0S 178.3W
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 271800Z INDICATES THAT A CIRCULATION CENTER IS LOCATED
NEAR 16.1S 178.7E. THE SYSTEM IS MOVING NORTHEASTWARD AT 04
KNOTS.
2. REMARKS: THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 18.1S
178.6E, IS NOW LOCATED NEAR 16.1S 178.7E, APPROXIMATELY 120 NM EAST
OF NADI, FIJI. ANIMATED INFRARED SATELLITE IMAGERY SHOWS FLARING
FORMATIVE CONVECTIVE BANDING WRAPPING AROUND A POORLY DEFINED LOW
LEVEL CIRCULATION CENTER. A 271718Z SSMIS MICROWAVE IMAGE SHOWS A
DEFINED SYSTEM DESPITE THE CONVECTIVE ORGANIZATION OF THE SYSTEM
REMAINING FAIRLY BROKEN. THE RADAR LOOP FROM LABASA, FIJI, IS
SHOWING THE LOW LEVEL STRUCTURE OF THE SYSTEM IS ILL DEFINED AS THE
ISLANDS SEEM TO BE DISRUPTING THE LOW-LEVEL INFLOW. UPPER-LEVEL
ANALYSIS INDICATES THE SYSTEM IS LOCATED NEAR THE RIDGE AXIS IN AN
AREA OF LOW (05 TO 10 KNOTS) VERTICAL WIND SHEAR AND FAVORABLE
POLEWARD AND EQUATORWARD OUTFLOW. SEA SURFACE TEMPERATURES ARE
CONDUCIVE FOR DEVELOPMENT (30 DEGREES CELSIUS). NUMERICAL MODELS
INDICATE SIGNIFICANT DEVELOPMENT OVER THE NEXT 48 HOURS AS THE
SYSTEM MOVES POLEWARD FROM THE ISLANDS OF FIJI. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 999 MB. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS HIGH.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
282100Z.

REMARKS:
280900Z POSITION NEAR 16.5S 179.2W.
TROPICAL CYCLONE (TC) 16P (SIXTEEN), LOCATED APPROXIMATELY 170 NM
NORTHEAST OF SUVA, FIJI, HAS TRACKED EAST-SOUTHEASTWARD AT 09
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY (MSI) SHOWS THE SYSTEM HAS FURTHER CONSOLIDATED AS FORMATIVE
BANDS WRAPPED TIGHTER INTO A LOW LEVEL CIRCULATION CENTER THAT HAS
BECOME BETTER-DEFINED. THE INITIAL POSITION IS BASED ON THE MSI LOOP
WITH FAIR CONFIDENCE. THE INITIAL INTENSITY IS BASED ON THE HIGHER
END OF DVORAK ESTIMATES FROM PGTW, KNES, NFFN, AND ABRF. UPPER LEVEL
ANALYSIS INDICATES THE SYSTEM IS UNDER A RIDGE AXIS IN AN AREA OF
LIGHT TO MODERATE (10-15 KNOT) VERTICAL WIND SHEAR (VWS) AND GOOD
POLEWARD OUTFLOW. A MID-LAYERED SUBTROPICAL RIDGE TO THE EAST HAS
ASSUMED STEERING AND IS EXPECTED TO BE THE DOMINANT DRIVER OF THE
CYCLONE THROUGHOUT THE FORECAST. TC 16P WILL GRADUALLY INTENSIFY,
PEAKING AT 60 KNOTS FROM TAU 72-96 BEFORE ACCELERATING TOWARDS
EXTRA-TROPICAL TRANSITION AND HIGHER VWS. THE AVAILABLE NUMERIC
GUIDANCE IS IN TIGHT AGREEMENT, LENDING HIGH CONFIDENCE TO THE JTWC
TRACK FORECAST. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 280600Z IS 10
FEET. NEXT
WARNINGS AT 282100Z AND 010900Z. THIS WARNING SUPERSEDES AND

REMARKS:
282100Z POSITION NEAR 18.0S 178.7W.
TROPICAL CYCLONE (TC) 16P (SIXTEEN), LOCATED APPROXIMATELY 157 NM
EAST OF SUVA, FIJI, HAS TRACKED SOUTH-SOUTHEASTWARD AT 09 KNOTS
OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY DEPICTS CURVED CONVECTIVE BANDING WRAPPING BROADLY INTO THE
LOW-LEVEL CIRCULATION CENTER (LLCC). A 281802Z SSMIS IMAGE SHOWS A
DEFINED BUT ELONGATED LLCC. RECENT SCATTEROMETRY DATA ALSO REVEALS A
BROAD CIRCULATION WITH 25 TO 30 KNOT WINDS WHILE SURFACE
OBSERVATIONS SHOW SLP NEAR 997MB, WHICH CORRESPONDS TO 30 T0 35 KNOT
MAXIMUM SUSTAINED SURFACE WINDS. THE CURRENT INTENSITY REMAINS
ASSESSED AT 35 KNOTS BASED ON DVORAK ESTIMATES OF 35 KNOTS FROM ALL
AGENCIES. THE CURRENT POSITION IS BASED ON THE AFOREMENTIONED SSMIS
IMAGE WITH FAIR CONFIDENCE. TC 16P IS TRACKING ALONG THE WESTERN
PERIPHERY OF THE SUBTROPICAL RIDGE (STR) AND IS FORECAST TO
GRADUALLY ACCELERATE AFTER TAU 36 AS IT BEGINS TO TRACK INTO AN AREA
OF ENHANCED POLEWARD FLOW SITUATED BETWEEN THE STR AND AN
APPROACHING DEEP MIDLATITUDE TROUGH. BY TAU 48, TC 16P SHOULD BEGIN
EXTRA-TROPICAL TRANSITION (ETT) AS IT INTERACTS WITH THE TROUGH AND
BAROCLINIC ZONE. AFTER TAU 72, THE SYSTEM WILL ENCOUNTER INCREASING
VERTICAL WIND SHEAR AND COOLER SST, WHICH WILL SERVE TO WEAKEN THE
SYSTEM RAPIDLY. TC 16P IS FORECAST TO COMPLETE ETT BY TAU 96 AS IT
BECOMES FULLY-EMBEDDED IN THE BAROCLINIC ZONE AND GAINS FRONTAL
CHARACTERISTICS. THERE IS HIGH CONFIDENCE IN THE FORECAST DUE TO THE
TIGHT GROUPING OF DYNAMIC GUIDANCE. MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 281800Z IS 11 FEET. NEXT WARNINGS AT 010900Z AND 012100Z.//

TROPICAL CYCLONE (TC) 16P (KOFI), LOCATED APPROXIMATELY 305 NM EAST-

REMARKS:
012100Z POSITION NEAR 22.8S 174.9W.
TROPICAL CYCLONE (TC) 16P (KOFI), LOCATED APPROXIMATELY 435 NM
SOUTHEAST OF SUVA, FIJI, HAS TRACKED SOUTHEASTWARD AT 10 KNOTS OVER
THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED IMAGERY DEPICTS
CURVED CONVECTIVE BANDING WRAPPING BROADLY INTO THE LOW-LEVEL
CIRCULATION CENTER (LLCC). A 011653Z SSMIS IMAGE SHOWS A PARTIALLY-
EXPOSED LLCC ON THE NORTHWEST EDGE OF THE DEEP CONVECTIVE BANDING.
RECENT SURFACE OBSERVATIONS FROM NFTF (21.2S 175.1W), APPROXIMATELY
70 NM NORTH OF THE CENTER, INDICATE MAXIMUM SUSTAINED NORTHERLY
WINDS AT 28 KNOTS GUSTING TO 48 KNOTS WITH A MINIMUM SLP NEAR 993
MB. THE CURRENT INTENSITY REMAINS ASSESSED AT 45 KNOTS BASED ON
DVORAK ESTIMATES OF 45 KNOTS FROM ALL AGENCIES. THE CURRENT POSITION
IS BASED ON THE AFOREMENTIONED SSMIS IMAGE WITH FAIR CONFIDENCE. TC
16P IS TRACKING ALONG THE WESTERN PERIPHERY OF THE SUBTROPICAL RIDGE
(STR) AND IS FORECAST TO GRADUALLY ACCELERATE AFTER TAU 24 AS IT
BEGINS TO TRACK INTO AN AREA OF ENHANCED POLEWARD FLOW SITUATED
BETWEEN THE STR AND AN APPROACHING DEEP MIDLATITUDE TROUGH. BY TAU
24, TC 16P SHOULD BEGIN EXTRA-TROPICAL TRANSITION (ETT) AS IT
INTERACTS WITH THE TROUGH AND BAROCLINIC ZONE. AFTER TAU 36, THE
SYSTEM WILL ENCOUNTER INCREASING VERTICAL WIND SHEAR AND COOLER SST,
WHICH WILL SERVE TO WEAKEN THE SYSTEM RAPIDLY. TC 16P IS FORECAST TO
COMPLETE ETT BY TAU 48 AS IT BECOMES FULLY-EMBEDDED IN THE
BAROCLINIC ZONE AND GAINS FRONTAL CHARACTERISTICS. THERE IS HIGH
CONFIDENCE IN THE FORECAST DUE TO THE TIGHT GROUPING OF DYNAMIC
GUIDANCE. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 011800Z IS 18 FEET. NEXT

A CENTRAL DENSE OVERCAST FEATURE WITH A CURVED CONVECTIVE BAND OVER
THE NORTHERN SEMI-CIRCLE OF THE LOW-LEVEL CIRCULATION CENTER (LLCC).
A 021738Z SSMIS 37V IMAGE REVEALS A WELL-DEFINED LLCC WITH TIGHTLY-

ASSESSED AT 50 KNOTS, SLIGHTLY HIGHER THAN THE DVORAK INTENSITY
ESTIMATES OF 45 KNOTS, BASED ON A 020949Z ASCAT IMAGE SHOWING 45 TO
50 KNOT WINDS. TC 16P IS TRACKING ALONG THE SOUTHWESTERN PERIPHERY
OF THE SUBTROPICAL RIDGE (STR) AND IS FORECAST TO GRADUALLY
ACCELERATE AS IT BEGINS TO TRACK INTO AN AREA OF ENHANCED POLEWARD
FLOW SITUATED BETWEEN THE STR AND A DEEP MIDLATITUDE TROUGH. BY TAU

TROPICAL CYCLONE (TC) 16P (KOFI), LOCATED APPROXIMATELY 1034 NM
SOUTH-SOUTHEAST OF PAGO PAGO, HAS ACCELERATED EAST-SOUTHEASTWARD AT
28 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY (MSI) SHOWS THE SYSTEM HAS GROSSLY ELONGATED AS THE
CONVECTION BECAME DISPLACED SOUTHEASTWARD, PARTIALLY EXPOSING THE LOW
LEVEL CIRCULATION CENTER. THE INITIAL POSITION IS BASED ON THE MSI
ANIMATION WITH HIGH CONFIDENCE. THE INITIAL INTENSITY IS DEDUCED FROM
A 030843Z SCATTEROMETRY PASS. UPPER LEVEL ANALYSIS INDICATES TC KOFI
HAS DRIFTED WELL SOUTH OF THE RIDGE AXIS INTO AN AREA OF STRONG
(GREATER THAN 30 KNOT) VERTICAL WIND SHEAR. FURTHERMORE, A SATELLITE
CROSS-SECTION PRODUCT FROM CIRA INDICATES THE WARM CORE HAS BEEN
REDUCED TO 01 CELSIUS DEGREE. NEAR THE SURFACE, COLD-AIR ADVECTION IS
EVIDENT ON THE MSI LOOP. AT THE SURFACE, ALONG-TRACK SEA SURFACE
TEMPERATURES HAVE FALLEN TO BELOW 26 DEGREES CELSIUS. ALL DATA
INDICATE TC 16P IS FAST BECOMING EXTRA-TROPICAL AND WILL BE A COLD
CORE LOW BY TAU 12. CONCURRENTLY, THE CYCLONE IS EXPECTED TO WEAKEN
TO BELOW JTWC WARNING THRESHOLD. THIS IS THE FINAL WARNING ON THIS
SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL HARBOR HI. THE SYSTEM WILL
BE CLOSELY MONITORED FOR SIGNS OF REGENERATION. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 031800Z IS 18 FEET.  //
