SUBJ/TROPICAL CYCLONE FORMATION ALERT 242051ZJAN03//
RMKS/
1. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
A 150 NM RADIUS OF 12.6S9 162.0E9 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 241730Z7 INDICATES THAT A
CIRCULATION CENTER IS LOCATED NEAR 12.6S9 162.0E9. THE SYSTEM IS
MOVING SOUTHEASTWARD AT 04 KNOTS.
2. REMARKS: A BROAD CYCLONIC CIRCULATION HAS DEVELOPED APPROXIMATELY
240 NM SOUTH OF THE SOLOMON ISLANDS. ANIMATED INFRARED SATELLITE
IMAGERY INDICATES INCREASING ORGANIZATION AND DEEP CONVECTION DURING
THE PAST 12 HOURS. RECENT TROPICAL RAINFALL MEASURING MISSION (TRMM)
AND QUIKSCAT PASSES INDICATE THAT THE BROAD CIRCULATION IS
CONSOLIDATING. UPPER-LEVEL ANALYSIS INDICATES THAT THE DISTURBANCE
IS LOCATED IN A FAVORABLE OUTFLOW ENVIRONMENT, WITH WEAK VERTICAL
WIND SHEAR. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE 1002 MB.
THE POTENTIAL FOR DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS GOOD.
3. THIS ALERT WILL BE REISSUED, UPGRADED TO WARNING OR CANCELLED BY
252100Z0.//

REMARKS:
250300Z0 POSITION NEAR 13.0S4 161.3E1.
TROPICAL CYCLONE (TC) 12P (BENI), LOCATED APPROXIMATELY 230 NM SOUTH
OF HONIARA, SOLOMON ISLANDS, HAS TRACKED WEST-SOUTHWEST AT 04 KNOTS
DURING THE PAST SIX HOURS. THE WARNING POSITION IS BASED ON 242330Z4
ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON SATELLITE CURRENT INTENSITY ESTIMATES OF 30 AND 35 KNOTS. RECENT
MICROWAVE IMAGERY INDICATES INCREASING ORGANIZATION AND ANIMATED
INFRARED SATELLITE IMAGERY DEPICTS FAVORABLE OUTFLOW CHANNELS BOTH
EQUATORWARD AND POLEWARD. THE SYSTEM IS FORECAST TO TRACK SLOWLY
WEST-SOUTHWEST THROUGH 36 HOURS, THEN SOUTH AFTERWARDS, ALONG THE
NORTHERN EDGE OF THE LOW TO MID-LEVEL SUBTROPICAL STEERING RIDGE,
WHILE INCREASING IN INTENSITY AT A CLIMATOLOGICAL RATE. THE
AVAILABLE DYNAMIC AIDS CONSISTING OF NGPS, NCEP AVIATION (AVN), AND
UKMET GLOBAL (EGRR) ARE IN REASONABLE AGREEMENT WITH THIS SCENARIO.
OUR FORECAST IS BASED ON PERSISTENCE AND A CONSENSUS OF THE
AVAILABLE DYNAMIC AIDS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 250000Z7
IS 10 FEET. THIS WARNING SUPERSEDES AND CANCELS REF A,

251500Z3 POSITION NEAR 13.3S7 160.5E2.
TROPICAL CYCLONE (TC) 12P (BENI), LOCATED APPROXIMATELY 235 NM SOUTH
OF HONIARA, SOLOMON ISLANDS, HAS TRACKED WEST-SOUTHWESTWARD AT 04
KNOTS DURING THE PAST SIX HOURS. THE WARNING POSITION IS BASED ON
251130Z2 ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY
IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 30 AND 35
KNOTS. RECENT MICROWAVE IMAGERY INDICATES THE LOW LEVEL CIRCULATION
CENTER (LLCC) IS PARTIALLY EXPOSED WITH THE DEEP CONVECTION TO THE
WEST OF THE LLCC. ANIMATED INFRARED SATELLITE IMAGERY DEPICTS
FAVORABLE POLEWARD OUTFLOW, BUT ONLY SLIGHT INCREASES IN DEVELOPMENT
OVER THE PAST 12 HOURS. THE SYSTEM IS FORECAST TO TRACK SLOWLY
WEST-SOUTHWESTWARD TO WESTWARD THROUGH THE NEXT 24 HOURS, THEN SOUTH
TO SOUTH-SOUTHEASTWARD UNDER THE INFLUENCE OF THE LOW TO MID LEVEL,
NEAR EQUATORIAL, STEERING RIDGE EAST-NORTHEAST OF THE SYSTEM.
INTENSITY IS FORECAST TO INCREASE AT A CLIMATOLOGICAL RATE THROUGHOUT
THE PERIOD. THE AVAILABLE DYNAMIC AIDS CONSISTING OF NOGAPS, GFDN, NCEP
AVIATION (AVN), JAPANESE GLOBAL (JGSM), AND UKMET GLOBAL (EGRR) ARE IN
GOOD AGREEMENT WITH THIS SCENARIO. OUR FORECAST IS BASED ON PERSISTENCE
AND A CONSENSUS OF ALL AVAILABLE DYNAMIC AIDS. MAXIMUM SIGNIFICANT WAVE

271500Z5 POSITION NEAR 14.1S6 161.1E9.
TROPICAL CYCLONE (TC) 12P (BENI), LOCATED APPROXIMATELY 275 NM
SOUTH-SOUTHEAST OF HONIARA, SOLOMON ISLANDS, HAS TRACKED SOUTHEAST
AT 05 KTS DURING THE PAST SIX HOURS. THE WARNING POSITION IS BASED
ON 271130Z4 ENHANCED INFRARED SATELLITE IMAGERY. THE WARNING
INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 55
AND 65 KNOTS. RECENT MICROWAVE SATELLITE IMAGERY INDICATES THAT DRY
AIR CONTINUES TO BE ENTRAINED FROM THE SOUTH AND THE LOW LEVEL
CIRCULATION CENTER (LLCC) REMAINS PARTIALLY EXPOSED IN THE EASTERN
SEMICIRCLE. THE SYSTEM IS FORECAST TO TRACK GENERALLY POLEWARD OVER
THE NEXT 18 TO 24 HOURS UNDER THE INFLUENCE OF THE LOW TO MID-LEVEL
RIDGE TO THE NORTHEAST. AS THE MID-LEVEL RIDGE OVER AUSTRALIA BUILDS
TOWARDS THE EAST AND THE MID-LEVEL TROUGH OVER SOUTHERN AUSTRALIA
DEEPENS AND MOVES EASTWARD, THE SYSTEM WILL BEGIN A MORE
SOUTHEASTWARD TRACK, FOLLOWING THE WEAKNESS IN THE RIDGE. TC 12P IS
FORECAST TO INTENSIFY VERY SLOWLY THROUGH THE PERIOD, PEAKING AFTER
THE EARLY PERIOD. THE AVAILABLE DYNAMIC AIDS, CONSISTING OF NOGAPS,
GFDN, NCEP AVIATION (AVN), AFWA MM5, AND UKMET GLOBAL (EGRR) MODELS
ARE IN REASONABLE AGREEMENT WITH THIS SCENARIO. OUR FORECAST IS
BASED ON A BLEND OF PERSISTENCE AND ALL OF THE AVAILABLE DYNAMIC
AIDS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 271200Z2 IS 18 FEET.

REMARKS:
301500Z9 POSITION NEAR 21.4S7 169.1E7.
TROPICAL CYCLONE (TC) 12P (BENI), LOCATED APPROXIMATELY 165 NM
EAST-NORTHEAST OF NOUMEA, NEW CALEDONIA, HAS TRACKED SOUTH-
SOUTHEASTWARD AT 12 KNOTS DURING THE PAST SIX HOURS. THE WARNING
POSITION IS BASED ON 301130Z8 ENHANCED INFRARED SATELLITE IMAGERY.
THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY
ESTIMATES OF 65 TO 90 KNOTS. RECENT MICROWAVE IMAGERY DEPICTS A
PARTIALLY EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) WITH
DECREASING DEEP CONVECTION REMAINING PRIMARILY TO THE SOUTHEAST OF
THE LLCC. THE SYSTEM IS FORECAST TO TRACK SOUTH THROUGH THE NEXT 12
HOURS AS THE LOW TO MID-LEVEL RIDGE TO THE SOUTHEAST OF THE SYSTEM
BUILDS. AFTERWARDS, A SOUTHWESTWARDS TRACK IS FORECAST AS A
DEEPENING TROUGH IS PROPAGATES EASTWARD, FROM TASMANIA, TO THE SOUTH
OF THE SYSTEM INFLUENCING A WEAKNESS IN THE RIDGE. TC 12P IS
FORECAST TO TRACK POLEWARD TOWARD THE WEAKNESS THROUGHOUT THE
REMAINDER OF THE FORECAST PERIOD. THE SYSTEM HAS WEAKENED RAPIDLY
OVER THE PAST 12 HOURS AND IS EXPECTED TO CONTINUE TO WEAKEN AS IT
TRACKS POLEWARD OF THE UPPER LEVEL RIDGE AXIS AND ENCOUNTERS
INCREASING VERTICAL WIND SHEAR. THE AVAILABLE DYNAMIC AIDS,
CONSISTING OF NOGAPS, GFDN, NCEP AVIATION (AVN), AND UKMET GLOBAL
(EGRR) MODELS ARE IN GOOD AGREEMENT WITH THIS SCENARIO. OUR FORECAST
IS BASED ON PERSISTENCE AND A BLEND OF ALL AVAILABLE DYNAMIC AIDS.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 301200Z6 IS 24 FEET. NEXT
