1. IMMEDIATE DELIVERY REQ TO AMEMBASSY SUVA
2. IMMEDIATE DELIVERY REQ TO AMEMBASSY PORT MORESBY AND AMEMBASSY
HONIARA SOLOMON ISLANDS
3. FORMATION OF A SIGNIFICANT TROPICAL CYCLONE IS POSSIBLE WITHIN
140 NM EITHER SIDE OF A LINE FROM 21.3S6 152.3E1 TO 21.4S7
158.9E3 WITHIN THE NEXT 03 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 15 TO 25 KNOTS.
METSAT IMAGERY AND SYNOPTIC DATA AT 162130Z INDICATE THAT A
CIRCULATION CENTER IS LOCATED NEAR 21.4S7 152.4E2. THE SYSTEM IS
MOVING EASTWARD AT 10 KNOTS.
4. REMARKS: AN AREA OF CONVECTION WITH AN ASSOCIATED LOW-LEVEL
CIRCULATION CENTER (LLCC) HAS MOVED OFF THE AUSTRALIAN COAST AND
CONTINUES TO MOVE EASTWARD TOWARDS NEW CALEDONIA. VISIBLE SATELLITE
IMAGERY SHOWS A WELL-DEFINED LLCC WITH DEEP CONVECTION. SYNOPTIC
DATA INDICATES PRESSURE DROPS AND A CLOSED CIRCULATION. ANIMATED
WATER VAPOR IMAGERY INDICATES A MID-LATITUDE TROUGH SOUTHWEST AND
AN UPPER-LEVEL LOW SOUTHEAST. OUTFLOW IS GOOD AND WINDSHEAR IS
FAVORABLE FOR FURTHER DEVELOPMENT. THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS GOOD.

REMARKS:
170900Z7 POSITION NEAR 21.4S7 155.7E8.
TROPICAL CYCLONE 22P HAS TRACKED TOWARDS THE EAST AT 13 KNOTS
DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 170530Z6
VISIBLE SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED ON
SATELLITE CURRENT INTENSITY ESTIMATES OF T2.5 (35 KNOTS). TC 22P
HAS TRACKED WITHIN A PORTION OF THE MONSOON TROUGH AND UNDER THE
STEERING INFLUENCE OF RIDGING TO THE NORTH. TC 22P IS FORECAST TO
CONTINUE ON AN EASTWARD TRACK DURING THE NEXT 12 HOURS. AFTERWHICH,
THE SYSTEM IS EXPECTED TO SLOW AND TURN MORE TOWARDS THE EAST-
NORTHEAST IN RESPONSE TO A BROAD MID LEVEL CYCLONE CURRENTLY EAST-
SOUTHEAST OF THE SYSTEM. TC 22P IS FORECAST TO RETURN TO A MORE
EASTWARD TRACK AFTER THE 48 HOUR FORECAST POSITION. CONDITIONS
REMAIN FAVORABLE AHEAD OF THE SYSTEM FOR FURTHER DEVELOPMENT
DURING THE FIRST 36 TO 48 HOURS. SLIGHTLY INCREASED SHEAR BETWEEN
THE MID LEVEL CYCLONE AND THE RIDGE TO THE NORTH WILL INHIBIT SOME
DEVELOPMENT AFTER THAT PERIOD. TC 22P IS FORECAST TO INTENSIFY
NEAR CLIMATOLOGICALLY THROUGHOUT THE FIRST 36 HOUR. AFTERWARDS, THE
SYSTEM WILL MAINTAIN ITS INTENSITY FOR THE REMAINDER OF THE 72 HOUR
FORECAST PERIOD. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 170600Z4 IS 14

REMARKS:
172100Z1 POSITION NEAR 20.9S1 158.1E5.
TROPICAL CYCLONE 22P CONTINUES TO TRACK EAST-NORTHEASTWARD AT 12
KNOTS IN THE CORAL SEA. ANIMATED INFRARED SATELLITE IMAGERY INDICATES
ALL DEEP CONVECTION ASSOCIATED WITH THE SYSTEM CENTER HAS DISSIPATED,
HOWEVER A STRONG CONVECTIVE BAND EXISTS TO THE NORTH. 171236Z0 SCATTEROMETER
DATA INDICATES THE STRONGEST WINDS ARE 30 KNOTS IN THE NORTHERN QUADRANT.
UPPER-LEVEL OUTFLOW OVER THE SYSTEM REMAINS GOOD IN ALL QUADRANTS AND IS
ORIENTED ANTICYCLONICALLY. THE WARNING POSITION AND INTENSITY ARE BASED
ON 171730Z9 INFRARED SATELLITE INTENSITY ESTIMATES OF 25 AND 35 KNOTS
AUGMENTED BY THE SCATTEROMETER DATA. TROPICAL CYCLONE 22P IS FORECAST
TO TRACK EAST-NORTHEASTWARD THROUGH 36 HOURS UNDER THE STEERING INFLUENCE
OF A MID-LEVEL RIDGE TO ITS NORTHWEST. AFTER 36 HOURS THIS SYSTEM
IS ANTICIPATED TO TURN TOWARD THE EAST-SOUTHEAST IN RESPONSE TO AN
APPROACHING MID-LEVEL TROUGH AND A MID-LEVEL RIDGE TO THE EAST. TC 22P
IS FORECAST TO SLOWLY INTENSIFY THROUGHOUT THE FORECAST PERIOD AS THE
UPPER-LEVEL ANTICYCLONE INDUCES REGENERATION OF DEEP CONVECTION OVER
THE SYSTEM CENTER. WIND RADII ARE EXTRAPOLATED FROM SCATTEROMETER DATA.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 171800Z7 IS 14 FEET. REFER TO WWPW30
PGFW FOR ADDITIONAL SEA HEIGHT INFORMATION. NEXT WARNINGS AT 180300Z2

REMARKS:
192100Z3 POSITION NEAR 20.4S6 164.9E0.
TROPICAL CYCLONE 22P (FRANK) HAS TRACKED TOWARDS THE EAST AT 9
KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON
191730Z1 INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON SATELLITE CURRENT INTENSITY ESTIMATES OF T4.5 (77 KNOTS) AND
T4.0 (65 KNOTS-KGWC). TC 22P (FRANK) WAS LOCATED OVER THE NORTHERN
TIP OF NEW CALEDONIA AND HAS REMAINED UNDER THE STEERING FLOW
OF THE RIDGE TO THE NORTH. A SLOWLY BUIDING RIDGE TO THE EAST OF
THE SYSTEM, COUPLED WITH AND APPROACHING TROUGH TO THE WEST OF THE
SYSTEM IS EXPECTED TO BECOME THE DOMINANT STEERING FLOW FOR TC 22P
(FRANK) AFTER THE NEXT 24 HOURS. TC 22P (FRANK) IS FORECAST TO
CONTINUE ON A MOSTLY EAST TO EAST-SOUTHEAST TRACK DURING THE
INITIAL 24 HOURS. AFTERWARDS, TC 22P (FRANK) IS FORECAST TO BEGIN
TRACKING TOWARDS THE SOUTHEAST AS THIS NEW STEERING FLOW BEGINS
TO DOMINATE THE SYSTEMS TRACK. OUTFLOW OVER THE SYSTEM REMAINS
GOOD. ANIMATED WATER VAPOR IMAGERY INDICATES THE SYSTEM IS WITHIN A
MINIMAL SHEAR ENVIRONMENT. INCREASING SHEAR BETWEEN THE RIDGE TO
THE EAST AND THE TROUGH TO THE WEST WILL BEGIN TO HINDER AND EVEN
WEAKEN THE SYSTEM AFTER THE 36 HOUR FORECAST PERIOD. TC 22P (FRANK)
IS FORECAST TO INTENSIFY CLIMATOLOGICALLY DURING THE NEXT 36 HOURS.
AFTERWARD, THE SYSTEM IS FORECAST TO BEGIN WEAKENING THROUGHOUT THE
REMAINDER OF THE FORECAST PERIOD. MAXIMUM SIGNIFICANT WAVE HEIGHT

TROPICAL CYCLONE 22P (FRANK) HAS TRACKED TOWARDS THE EAST-SOUTHEAST
AT 8 KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED
ON 192330Z8 VISIBLE SATELLITE IMAGERY. THE WARNING INTENSITY IS
BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF T5.5 (100KTS). TC
22P (FRANK) HAS RAPIDLY INTENSIFIED AND DEVELOPED AN EYE FEATURE.
ADDITIONALLY, TC 22P (FRANK) HAS BEGUN TO TRACK EAST-
SOUTHEASTWARDLY SOONER THAN PREVIOUSLY FORECAST. THE SYSTEM IS
CURRENTLY TRACKING ALONG THE EASTERN COAST OF NEW CALEDONIA UNDER
THE STEERING FLOW OF THE BUILDING RIDGE TO THE EAST AND AN
APPROACHING TROUGH FROM THE WEST. BOTH OF THESE STEERING FLOWS
WILL COMBINE TO TRACK TC 22P (FRANK) MORE TOWARDS THE SOUTH THROUGH
THE 36 HOUR FORECAST POSITION. AFTERWARDS, TC 22P (FRANK) IS
FORECAST TO TRACK SLIGHTLY MORE TOWARDS THE EAST AS THE STEERING
FLOW WEAKENS TEMPORARILY. INTERACTION WITH LAND SHOULD INHIBIT ANY
FURTHER DRASTIC INCREASES IN INTENSITY. HOWEVER, GOOD OUTFLOW ALOFT
AND LOW VERTICAL SHEAR MAY ALLOW FOR A SLIGHT INCREASE THROUGH THE
24 HOUR FORECAST PERIOD. AFTERWARDS, INCREASING SHEAR BETWEEN THE
RIDGE AND THE TROUGH SHOULD BEGIN TO WEAKEN THE SYSTEM AS TC 22P
(FRANK) CONTINUES TO TRACK TOWARDS THE SOUTHEAST. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 200000Z IS 21 FEET. THIS WAS AN
ADDITIONAL WARNING DUE TO THE SIGNIFICANT CHANGE IN THE SYSTEMS
INTENSITY. THE JOINT TYPHOON WARNING CENTER WILL NOW RESUME 12
HOURLY WARNING. NEXT WARNINGS AT 201500Z8 (DTG 201353Z4) AND

202330Z0 VISIBLE SATELLITE IMAGERY. THE WARNING INTENSITY IS BASED
ON SATELLITE CURRENT INTENSITY ESTIMATES OF T4.5 (77 KNOTS). THE
LOW LEVEL CIRCULATION ASSOCIATED WITH TC 22P (FRANK) HAS BECOME
ALMOST FULLY EXPOSED DURING THE PAST 6 HOURS. THE CENTER OF THE
SYSTEM HAS BEEN RELOCATED WEST-NORTHWEST OF THE PREVIOUS WARNING
POSITION DUE TO RECENTLY AVAILABLE VISIBLE IMAGERY. THE PHILOSOPHY
OF THE PREVIOUS FORECAST REMAINS ABOUT THE SAME. TC 22P (FRANK) HAS
REMAINED UNDER THE STEERING INFLUENCE OF THE SUBTROPICAL RIDGE TO
THE EAST. THE LOWER LEVELS OF THE RIDGE ARE BUILDING TO THE
SOUTHEAST OF THE SYSTEM. THIS CHANGING STEERING FLOW IS EXPECTED
TO TRACK TC 22P (FRANK) TOWARDS THE SOUTHWEST AFTER 12 HOURS
AND THROUGH THE REMAINDER OF THE FORECAST PERIOD. TC 22P (FRANK)
WILL CONTINUE TO UNDERGO SIGNIFICANT NORTHWESTWARD SHEAR, BUT THE
LOW LEVEL WINDFIELD IS EXPECTED TO REMAIN INTACT AS IT CONTINUES TO
WEAKEN. INTERMITTENT INCREASES IN CONVECTION MAY OCCUR. THE OVERALL
TREND, HOWEVER, LEADS TO A DISSIPATING SYSTEM. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 210000Z IS 21 FEET. THIS IS AN ADDITIONAL WARNING TO
RELOCATE THE SYSTEM. THE NEXT WARNING IS AT 210900Z2 (DTG 210753Z8)
AND THEN 222100Z7 (DTG 221953Z2).//

REMARKS:
210900Z2 POSITION NEAR 25.5S2 164.2E3.
TROPICAL CYCLONE 22P (FRANK) HAS TRACKED SOUTHWESTWARD AT 9 KNOTS
OVER THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON 210530Z1
VISIBLE AND INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS
BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 65-77 KNOTS.
VISIBLE IMAGERY SHOWS A FULLY EXPOSED LOW-LEVEL CIRCULATION
CENTER SHEARED ABOUT 25NM NORTHWEST OF THE CONVECTION. SHIP
SYNOPTIC DATA INDICATES A BROAD 35KT WINDFIELD SOUTHEAST-SOUTHWEST
OF THE CIRCULATION, THE WIND RADII HAS BEEN ADJUSTED ACCORDINGLY.
TC 22P (FRANK) IS CAUGHT BETWEEN THE STEERING FLOW OF THE RIDGE TO
THE EAST AND THE MID-LEVEL RIDGE TO THE SOUTH-SOUTHWEST. THESE
STEERING INFLUENCES SHOULD RESULT IN AN OVERALL SOUTHWESTWARD TRACK
THROUGHOUT THE FORECAST. TC 22P (FRANK) WILL CONTINUE TO WEAKEN AS
NORTHWESTWARD SHEAR REMAINS MODERATE DUE TO AN UPPER LEVEL TROUGH
TO THE WEST. AS TC 22P TRACKS FURTHER SOUTHWARD IT WILL ALSO MOVE
OVER COOLER SEAS, AIDING THE WEAKENING PROCESS. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 210600Z9 IS 21 FEET. NEXT WARNINGS AT 212100Z6 (DTG
211953Z1) AND 220900Z3 (DTG 220753Z9).//

REMARKS:
212100Z6 POSITION NEAR 26.8S6 162.6E5.
TROPICAL CYCLONE 22P (FRANK) HAS TRACKED TOWARDS THE SOUTHWEST AT
12 KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION IS BASED
ON ANIMATED INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY IS
BASED ON 211730Z4 SATELLITE CURRENT INTENSITY ESTIMATES OF T4.0
(65 KNOTS) AND SUPPORTING PERIPHERAL SHIP REPORTS. THE FORECAST
PHILOSOPHY IS SIMILAR TO THAT OF THE PREVIOUS WARNING. THE
CONVECTION ASSOCIATED WITH TC 22P (FRANK) HAS CONTINUED TO BE
SHEARD TOWARDS THE SOUTH-SOUTHEAST. THE EXPOSED LOW LEVEL
CIRCULATION IS TRACKING WITHIN THE STEERING FLOW OF THE LOW LEVEL
SUBTROPICAL RIDGE THAT HAS BUILT SOUTEAST OF THE SYSTEM. TC 22P
(FRANK) IS FORECAST TO CONTINUE TO TRACK IN A GENERALLY
SOUTHWESTWARD DIRECTION DURING THE NEXT 24 HOURS. AFTERWARD, TC 22P
(FRANK) IS FORECAST TO TURN MORE TOWARDS THE SOUTH AS THE SYSTEM
MOVES AROUND THE SUBTROPICAL RIDGE AND INTO THE NORTHERN TASMAN
SEA. CONTINUED SHEAR AND COOLER SEA SURFACE TEMPERATURE WILL
CAUSE THE SYSTEM TO FURTHER WEAKEN. A 211211Z8 SCATTEROMETER IMAGE
CONFIRMED A BROAD AND STRONG WIND FIELD EXTENDING OVER THE SOUTHERN
HALF OF THE SYSTEM. THE WIND FIELDS, THEREFORE, HAVE BEEN ADJUSTED
ACCORDINGLY. TC 22P (FRANK) IS FORECAST TO CONTINUE TO WEAKEN,
FINALLY DISSIPATING OVER WATER BY THE 48 HOUR FORECAST PERIOD. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 211800Z IS 21 FEET. NEXT WARNINGS AT
220900Z3 (DTG 220753Z9) AND 222100Z7 (DTG 221953Z2).

REMARKS:
220900Z3 POSITION NEAR 27.0S9 161.3E1.
TROPICAL CYCLONE 22P (FRANK) HAS TRACKED WESTWARD AT 6 KNOTS DURING
THE PAST 6 HOURS. THE WARNING POSITION IS BASED ON VISIBLE AND
INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY (60 KTS) IS BASED
ON SATELLITE CURRENT INTENSITY ESTIMATES OF 55 KNOTS, SUPPORTING
PERIPHERAL SHIP REPORTS, AND A 212315Z4 SCATTEROMETER PASS. VISIBLE
IMAGERY SHOWS A FULLY EXPOSED LOW-LEVEL CIRCULATION CENTER (LLCC)
ABOUT 25NM NORTHEAST OF THE CONVECTION. THIS DE-COUPLING OF THE
STORM IS A RESULT OF INCREASING VERTICAL WINDSHEAR ASSOCIATED WITH
AN UPPER-LEVEL TROUGH TO THE WEST. SATELLITE ANIMATION SHOWS TC 22P
HAS TAKEN A MORE WESTWARD TRACK OVER THE PAST 6 HOURS. SYNOPTIC
DATA INDICATES THIS IS DUE TO A WEAK HIGH PRESSURE AREA JUST SOUTH
OF THE SYSTEM. THE OVERALL STEERING INFLUENCE REMAINS THE
SUBTROPICAL RIDGE TO THE EAST. TC 22P (FRANK) IS FORECAST TO
CONTINUE TO TRACK WEST-SOUTHWESTWARD FOR THE NEXT 12 HOURS IN
RESPONSE TO THE WEAKER RIDGE SOUTH. AFTERWARDS, TC 22P SHOULD
RESUME A SOUTHWESTWARD TRACK UNDER A COMBINATION OF THE STEERING
FLOW OF THE SUBTROPICAL RIDGE TO THE EAST AND THE WEAKENING RIDGE
TO THE SOUTH. CONTINUED VERTICAL WINDSHEAR AND COOLER SEA SURFACE
TEMPERATURES WILL CAUSE TC 22P TO CONTINUE TO WEAKEN THROUGHOUT
THE FORECAST PERIOD. THE LARGE ASSYMETRICAL WIND RADII IS BASED ON
EARLIER SCATTEROMETER DATA AND SYNOPTIC REPORTS OF 30-40 KNOTS WELL
SOUTH OF THE LLCC. WIND RADII ARE OMITTED FOR INTENSITIES OF 35 KTS
OR LESS. ALTHOUGH THE SYSTEM IS FORECAST TO WEAKEN TO 35 KNOTS AT
36 AND 48 HOURS, A LARGE 30 KNOT WINDFIELD CAN BE EXPECTED SOUTHWARD
OF THE LLCC. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 220600Z0 IS 21 FEET.
NEXT WARNINGS AT 222100Z7 (DTG 221953Z2) AND 230900Z4

INFRARED SATELLITE IMAGERY. THE WARNING INTENSITY (50 KTS) IS
BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 30 KNOTS,
EXTRAPOLATION AND 221800Z3 SHIP AND SYNOPTIC OBSERVATIONS.
INFRARED IMAGERY SHOWS A FULLY EXPOSED LOW-LEVEL CIRCULATION
CENTER (LLCC) DECOUPLED FROM THE CONVECTION DUE TO STRONG
VERTICAL WINDSHEAR. SATELLITE ANIMATION SHOWS TC 22P (FRANK)
HAS RESUMED ITS SOUTHWARD TRACK OVER DUE TO A WEAK HIGH

230900Z4 POSITION NEAR 30.1S4 163.3E3.
TROPICAL CYCLONE 22P (FRANK) HAS TRACKED SOUTH-SOUTHEASTWARD AT 19
KNOTS OVER THE PAST 06 HOURS. THE WARNING POSITION IS BASED ON
230530Z3 VISIBLE SATELLITE IMAGERY. THE WARNING INTENSITY (40 KTS)
IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF 35 KNOTS AND
230000Z5 SHIP OBSERVATIONS OF 35 KNOTS. ANIMATED VISIBLE SATELLITE
IMAGERY INDICATES THE LOW LEVEL CIRCULATION CENTER (LLCC) ASSOCIATED
WITH TC 22P (FRANK) IS BEGINNING TO ELONGATE WITH THE DEEP CONVECTION
SHEARED 15 NM SOUTH OF THE SYSTEM. INDEED, THE SYSTEM APPEARS TO BE
UNDERGOING EXTRA-TROPICAL TRANSITION AS WATER VAPOR IMAGERY SHOWS A
WELL DEFINED JET MOVING INTO THE CENTER OF THE SYSTEM. TROPICAL
CYCLONE 22P (FRANK) IS UNDER THE STEERING INFLUENCE OF THE
SUBTROPICAL RIDGE TO ITS NORTHEAST AND SHOULD CONTINUE TO TRACK
SOUTH-SOUTHEASTWARD FOR THE NEXT 12 HOURS. HOWEVER, TC 22P (FRANK)
IS FORECAST TO TRACK SOUTH-SOUTHWESTWARD BY THE 24 HOUR FORECAST
POSITION AS IT APPROACHES A MID-LEVEL RIDGE TO ITS SOUTH. ALTHOUGH
THE SATELLITE CURRENT INTENSITY ESTIMATE IS 35 KNOTS, THE INTENSITY
HAS BEEN INCREASED AND WIND RADII REMAIN CONSISTENT WITH THE
PREVIOUS FORECAST DUE TO SHIP OBSERVATIONS SOUTH OF TC 22P (FRANK).
TROPICAL CYCLONE 22P (FRANK) SHOULD UNDERGO EXTRATROPICAL TRANSITION
BY THE 24 HOUR FORECAST POSITION. MAXIMUM SIGNIFICANT WAVE HEIGHT
AT 230600Z1 IS 18 FEET. THIS IS THE FINAL WARNING ON THIS SYSTEM
BY THE JOINT TYPHOON WARNING CENTER (NAVPACMETOCCEN WEST GU). THE
SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION.//
