1. IMMEDIATE DELIVERY REQ TO AMEMBASSY SUVA
2. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
250 NM EITHER SIDE OF A LINE FROM 13.4S8 172.9E9 TO 20.6S8
172.9E9 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 230800Z3 INDICATES THAT A CIRCULATION CENTER IS
LOCATED NEAR 14.7S2 171.9E8.  THE SYSTEM IS MOVING SOUTHEASTWARD
AT 07 KNOTS.
3. REMARKS:
ANIMATED VISIBLE AND INFRARED IMAGERY DEPICT INCREASED
CONSOLIDATION OF THE CONVECTION OVER THE PAST 6 HOURS. OUTFLOW
CONTINUES TO BE IMPRESSIVE INDICATIVE OF THE UPPER-LEVEL RIDGE
SITUATED OVER THE SYSTEM. SYNOPTIC DATA INDICATES THE LOW-LEVEL
CIRCULATION CENTER IS EMBEDDED IN THE SOUTH PACIFIC CONVERGENCE
ZONE. MAXIMUM SUSTAINED WINDS ARE ESTIMATED AT 25 TO 30 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1000 MB. THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS NOW GOOD.

REMARKS:
240300Z9 POSITION NEAR 17.8S6 173.2E3.
TROPICAL CYCLONE (TC) 07P IS LOCATED APPROXIMATELY 250 NM WEST OF
SUVA, FIJI ISLANDS, AND HAS TRACKED SOUTHWARD AT 06 KNOTS OVER
THE PAST 6 HOURS. THE WARNING POSITION IS BASED UPON 232330Z3
VISIBLE SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED UPON
CURRENT INTENSITY ESTIMATES OF 35 AND 45 KNOTS. ANIMATED VISIBLE AND
INFRARED IMAGERY DEPICT INCREASING CONSOLIDATION OF DEEP CONVECTION
AROUND THE LOW-LEVEL CIRCULATION CENTER (LLCC), HOWEVER THE LLCC HAS
BECOME PARTIALLY EXPOSED IN THE PAST 3 HOURS. IMAGERY ALSO SHOWS TWO
CONVECTIVE BANDS LOCATED SOUTH AND NORTHWEST WRAPPING INTO THE
LLCC. ANIMATED WATER VAPOR IMAGERY SHOWS THAT THE SYSTEM HAS GOOD
OUTFLOW ALOFT IN ALL QUADRANTS. A 231750Z8 SPECIAL SENSOR MICROWAVE
IMAGER PASS SHOWS THAT THE SOUTHERN SPIRAL BAND EXTENDS FROM ABOUT
FOURTEEN DEGREES LATITUDE, POLEWARD INTO THE LLCC. SYNOPTIC DATA
SHOWS A WELL-DEFINED LLCC WITH STRONG CONVERGENCE NORTH-NORTHEAST OF
THE CENTER. BOTH THE 200 MB ANALYSIS AND THE UW-CIMSS CHARTS
INDICATE THAT TROPICAL CYCLONE 07P IS UNDER AN UPPER-LEVEL
ANTICYCLONE WITH WEAK TO MODERATE VERTICAL WIND SHEAR. TC 07P IS
FORECAST TO CONTINUE TRACKING SOUTHWARD UNDER THE STEERING INFLUENCE
OF THE MID-LEVEL SUBTROPICAL RIDGE TO THE NORTHEAST. HOWEVER, TC 07P
IS EXPECTED TO GRADUALLY TRACK MORE SOUTH-SOUTHWESTWARD AFTER THE 36
TO 48 HOUR FORECAST POINT AS THE RIDGE BUILDS SOUTH OF THE LLCC. TC
07P IS FORECAST TO INCREASE INTENSITY AT A NEAR CLIMATOLOGICAL RATE
DUE TO THE FAVORABLE ENVIRONMENT, BUT INTENSITY SHOULD BEGIN TO
LEVEL OFF TOWARD THE END OF THE FORECAST PERIOD AS TC 07P ENCOUNTERS
INCREASING VERTICAL WIND SHEAR ASSOCIATED WITH A MID-LATITUDE
TROUGH. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 240000Z6 IS 12 FEET. THIS

REMARKS:
241500Z2 POSITION NEAR 19.9S9 173.7E8.
TROPICAL CYCLONE (TC) 07P (JO) IS LOCATED APPROXIMATELY 240 NM WEST-
SOUTHWEST OF THE FIJI ISLANDS AND HAS TRACKED SOUTH-SOUTHEASTWARD AT
07 KNOTS OVER THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
241130Z1 INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON CURRENT INTENSITY ESTIMATES OF 35 AND 45 KNOTS. ANIMATED INFRARED
IMAGERY DEPICTS CONVECTION BUILDING OVER THE LOW-LEVEL CIRCULATION
CENTER (LLCC) FROM THE SOUTHEAST. 200 MB ANALYSIS REVEALS AN UPPER-
LEVEL HIGH SITUATED JUST TO THE NORTHEAST OF THE SYSTEM WHICH IS
PROVIDING NORTHEASTERLY DIFFLUENT FLOW OVER THE REGION. TC 07P (JO)
IS FORECAST TO TRACK SOUTH-SOUTHEASTWARD WITHIN THE STEERING FLOW
GENERATED BY THE MID-LEVEL RIDGE EXTENDING EQUATORWARD FROM THE
SAMOA ISLANDS AND A MAJOR SHORT WAVE TROUGH EXTENDING FROM NEW
ZEALAND TOWARD NEW CALEDONIA. TC 07P IS FORECAST TO INCREASE
INTENSITY AT A NEAR CLIMATOLOGICAL RATE WITH POSSIBLE HINDERING
VERTICAL WINDSHEAR EFFECTS WITH THE APPROACH OF THE TROUGH. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 241200Z9 IS 12 FEET. NEXT WARNINGS AT
250300Z0 (DTG 250151Z4) AND 251500Z3 (DTG 251351Z7).//

REMARKS:
261500Z4 POSITION NEAR 26.0S8 179.7E4.
TROPICAL CYCLONE (TC) 07P (JO), LOCATED APPROXIMATELY 435 NM
SOUTH OF SUVA, FIJI, HAS TRACKED SOUTHEASTWARD AT 17 KNOTS OVER THE
PAST SIX HOURS. THE WARNING POSITION IS BASED ON 261130Z3 INFRARED
SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON SATELLITE
CURRENT INTENSITY ESTIMATES OF 55 AND 65 KNOTS. ANIMATED INFRARED
SATELLITE IMAGERY INDICATES TC 07P (JO) REMAINS WELL ORGANIZED WITH
A 10 NM BANDING EYEWALL EVIDENT. ANIMATED WATER VAPOR IMAGERY
CONTINUES TO SHOW GOOD OUTFLOW ALOFT. A 260936Z6 SPECIAL SENSOR
MICROWAVE IMAGER (SSMI) PASS DEPICTS A BANDING FEATURE SOUTH OF THE
LOW LEVEL CIRCULATION CENTER. TC 07P (JO) IS FORECAST TO TRACK
EAST-SOUTHEASTWARD UNDER THE STEERING INFLUENCE OF THE MID-LEVEL
SUBTROPICAL RIDGE TO THE NORTHEAST. THE SYSTEM WILL GRADUALLY WEAKEN
AS IT MOVES INTO AN AREA OF GREATER VERTICAL WIND SHEAR. TC 07P (JO)
WILL BEGIN EXTRATROPICAL TRANSITION BY THE 36 HOUR FORECAST PERIOD.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 261200Z1 IS 18 FEET. NEXT
WARNINGS AT 270300Z2 (DTG 270151Z6) AND 271500Z5 (DTG 271351Z9).
REFER TO TROPICAL CYCLONE 08S (CONNIE) WARNINGS (WTXS32 PGTW) FOR
SIX-HOURLY UPDATES.

REMARKS:
270300Z2 POSITION NEAR 28.1S1  177.6W1.
TROPICAL CYCLONE (TC) 07P (JO), LOCATED APPROXIMATELY 590 NM
SOUTH-SOUTHEAST OF SUVA, FIJI, HAS TRACKED SOUTHEASTWARD AT 16 KNOTS 
OVER THE PAST SIX HOURS. THE WARNING POSITION IS BASED ON 262330Z6 
INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON 
SATELLITE CURRENT INTENSITY ESTIMATES OF 55 KNOTS. ANIMATED VISIBLE 
AND INFRARED SATELLITE IMAGERY INDICATES TC 07P (JO) HAS BEGUN TO 
SHEAR AS THE SYSTEM MOVES UNDER PRONOUNCED UPPER LEVEL WESTERLIES. 
SEA SURFACE ANALYSIS INDICATES COOLER SURFACE TEMPERATURES, NEAR 
23C, BENEATH THE SYSTEM WITH SATELLITE IMAGERY REVEALING COOL AIR 
STRATUS ADVECTING INTO THE CIRCULATION FROM THE SOUTH. TC 07P IS 
FORECAST TO BEGIN EXTRATROPICAL TRANSITION BY THE 12 HOUR PERIOD, 
BECOMING FULLY EXTRATROPICAL BY THE END OF THE 24 HOUR FORECAST 
PERIOD. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 270000Z9 IS 18 FEET. 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.//
