10S(JOSHUA). WARNING 6. 10S IS FORECAST TO MAINTAIN INTENSITY FOR THE NEXT 12 HOURS UNDER MARGINALLY SUPPORTIVE CONDITIONS BUT WILL WEAKEN STEADILY DUE TO INCREASING CONVERGENT FLOW ALOFT AND DRY AIR ENTRAINMENT, INTENSITY FALLING BELOW 35KNOTS OVER WATER BY 48H
12S(ELOISE). WARNING 2 ISSUED AT 17/21UTC. NEXT WARNING WILL BE ISSUED AT 18/09UTC. INTENSIFYING SYSTEM WITH FORECAST LANDFALL SOUTH OF ANTALAHA/MADAGASCAR SHORTLY AFTER 19/18UTC.
18/0230UTC
11P(KIMI). NUMERICAL MODEL GUIDANCE DISPLAYS A HIGH LEVEL OF UNCERTAINTY, WITH A SPLIT DECISION ON AN EASTWARD OR WESTWARD TRACK. THE HWRF, ECMWF AND GALWEM ULTIMATELY TURN THE SYSTEM TO THE WEST OVER AUSTRALIA, WHILE THE NAVGEM, COAMPS-TC AND GFS ENSEMBLE MEAN MOVE THE SYSTEM OFF TO THE EAST. THE REMAINDER OF THE CONSENSUS TRACKERS BRING THE SYSTEM TO A QUASI-STATIONARY MOTION BY 36H AND THEN TURN BACK NORTH. THE JTWC FORECAST TRACK HAS SHIFTED SOUTHWARDS ONCE MORE BUT REMAINS IN CONCURRENCE WITH THE PREVIOUS FORECAST IN TURNING THE SYSTEM INLAND OVER AUSTRALIA AFTER 36H AS IT WEAKENS AND COMES UNDER THE STEERING INFLUENCE OF THE SYNOPTIC LOW-LEVEL FLOW.
10S(JOSHUA). MODEL GUIDANCE IS IN GOOD AGREEMENT WITH A 95KM SPREAD AT 48H.
12S(ELOISE). NUMERICAL MODEL GUIDANCE IS IN GOOD AGREEMENT WITH 150KM SPREAD AT 48H, INCREASING TO 260KM AT 120H, LENDING OVERALL HIGH CONFIDENCE TO THE JTWC FORECAST TRACK.
