WTPS21 PGTW 990216 23:00z 162251Z FEB 99// RMKS/ 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. 5.

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.

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.

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.

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 PRESSURE AREA JUST EAST OF THE SYSTEM.

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.//
