WTXS22 PGTW 990119 18:30z 191821Z JAN 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 A 300 NM RADIUS OF 16.7S4 154.3E3 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 191251Z INDICATES THAT A CIRCULATION CENTER IS LOCATED NEAR 16.5S2 153.0E9. THE SYSTEM IS QUASI-STATIONARY AT 00 KNOTS. 4. REMARKS: A 191251Z9 SCATTEROMETER PASS INDICATES A BROAD CIRCULATION IN THE CORAL SEA ASSOCIATED WITH A PERSISTENT AREA OF CONVECTION. THE CIRCULATION APPEARS AS A DEVELOPING MONSOON DEPRESSION WITH MAXIMUM WINDS ON THE PERIPHERY OF THE LOW LEVEL CIRCULATION. ANIMATED INFRARED SATELLITE IMAGERY INDICATES SUSTAINED INTENSE CONVECTION OVER THE PAST 48 HOURS. SEA LEVEL PRESSURES ARE NEAR 997MB WITHIN THE MONSOON TROUGH. WATER VAPOR IMAGERY INDICATES GOOD OUTFLOW ALOFT. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS GOOD. 5.

COOLER SEA SURFACE TEMPERATURES AND INCREASING SHEAR IS EXPECTED TO HINDER SIGNIFICANT FURTHER DEVELOPMENT OF THE SYSTEMS AS IT CONTINUES ON ITS SOUTHEASTWARD TRACK. TC 13P (OLINDA), THEREFORE, IS FORECAST TO REMAIN ABOUT THE SAME INTENSITY OVER THE FORECAST PERIOD. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 230000Z IS 18 FEET.

THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF T2.5 (35 KNOTS) AND THE PREVIOUS WARNING. TC 13P (OLINDA) HAS CONTINUED TO MOVE UNDER THE STEERING INFLUENCE OF THE SUBTROPICAL RIDGE TO ITS NORTH. THE SYSTEM IS FORECAST TO CONTINUE WITHIN THIS STEERING FLOW DURING THE NEXT 24 HOURS, AFTER WHICH THE SYSTEM SHOULD ENTER A REGION OF WEAKER STEEING BETWEEN THE CURRENT DOMINANT RIDGE AND ANOTHER RIDGE TO THE EAST. TC 13P (OLINDA) IS FORECAST TO TURN MORE SOUTHEASTWARD IN RESPONSE TO THIS CHANGE IN STEERING FLOW AFTER THE 24 HOUR FORECAST PERIOD. AN ALTERNATIVE SCENERIO WOULD CONTINUE THE SYSTEM TOWARDS THE EAST-NORTHEAST IF THE CURRENT STEERING FLOW REMAINS DOMINANT.

THE WARNING INTENSITY IS BASED ON SATELLITE CURRENT INTENSITY ESTIMATES OF T2.0 (30 KNOTS). ANIMATED SATELLITE IMAGERY INDICATES TC 13P (OLINDA) HAS BECOME A SHEARED SYSTEM WITH ONLY THE LOW-LEVEL PORTION REMAINING AROUND THE SYSTEM, BUT IMAGERY SHOWS LITTLE CONVECTION. THE WIND RADII IS OMITTED FOR SYSTEMS 35 KNOTS OR LESS. SYNOPTIC DATA DOES INDICATE 30 KNOT WINDS EXTEND OUT APPROXIMATELY 180NM FROM THE SYSTEM CENTER. TC 13P (OLINDA) HAS CONTINUED TO MOVE UNDER THE STEERING INFLUENCE OF THE SUBTROPICAL RIDGE TO ITS EAST. THE SYSTEM IS FORECAST TO CONTINUE WITHIN THIS LOW-LEVEL STEERING FLOW AS IT TRANSITIONS TO AN EXTRATROPICAL CYCLONE BY THE 24 HOUR POINT.

TROPICAL CYCLONE 13P (OLINDA) HAS TRACKED TOWARDS THE EAST- SOUTHEAST AT 15 KNOTS DURING THE PAST 6 HOURS. THE WARNING POSITION AND INTENSITY ARE BASED ON EXTRAPOLATION FROM PREVIOUS THE WARNING WHICH UTILIZED SCATTEROMETER AND INFRARED SATELLITE IMAGES. TC 13P (OLINDA) WILL CONTINUE TO TRACK TOWARDS THE EAST-SOUTHEAST FOR THE REMAINDER OF THE FORECAST PERIOD UNDER THE STEERING INFLUENCE OF THE SHALLOW RIDGE TO THE NORTHEAST. THE SYSTEM HAS BECOME EXTRATROPICAL AND ALL THE ASSOCIATED CONVECTION HAS DISSIPATED. THE LOW LEVEL CIRCULATION, HOWEVER, HAS REMAINED INTACT AND WILL CONTINUE ON ITS CURRENT TRACK FOR THE REMAINDER OF THE PERIOD. THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WARNING CENTER (NAVPACMETOCCEN PEARL HARBOR). THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION. REFER TO TROPICAL CYCLONE 14P (PETE) WARNINGS (WTPS33 PGTW) FOR TWELVE- HOURLY UPDATES. REFER TO TROPICAL CYCLONE 15S (DAMIEN) WARNINGS (WTXS31 PGTW) FOR TWELVE-HOURLY UPDATES.//
