TROPICAL DISTURBANCE SUMMARY: NONE.\r\n   C. SUBTROPICAL SYSTEM SUMMARY: NONE.\r\n   B. TROPICAL DISTURBANCE SUMMARY:\r\n      (1) THE AREA OF CONVECTION (INVEST 99S) PREVIOUSLY LOCATED NEAR \r\n14.5S 106.7E IS NOW LOCATED NEAR 14.6S 105.7E, APPROXIMATELY 538 NM \r\nSOUTHEAST OF COCOS ISLANDS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY \r\n(MSI) DEPICTS AN ELONGATED AREA OF LOW LEVEL ROTATION WITH DEEP \r\nFLARING CONVECTION IN THE NORTH-NORTHWESTERN QUADRANT. STRONG WESTERLY \r\nFLOW ALONG THE 10S LATITUDE ARE HELPING 99S GAIN MORE MOMENTUM IN THE \r\nNEXT 24-36 HOURS. A 310124Z PARTIAL METOP-B ASCAT SCATTEROMETRY PASS \r\nREVEALS A WIND FIELD OF 25-30 KNOT WINDS IN THE NORTHERN PORTION OF \r\nTHE SEMICIRCLE APPROXIMATELY 150NM FROM THE CIRCULATION CENTER, WITH \r\nAREAS OF 15-20 KNOT WINDS BEGINNING TO WRAP INTO THE LLCC. \r\nENVIRONMENTAL ANALYSIS INDICATES THAT INVEST 99S IS IN A FAVORABLE \r\nENVIRONMENT FOR FURTHER DEVELOPMENT DUE TO WARM (29-30C) SEA SURFACE \r\nTEMPERATURES, GOOD POLEWARD OUTFLOW ALOFT, AND IS IN AN AREA OF LOW TO \r\nMODERATE (15 TO 20 KNOTS) VERTICAL WIND SHEAR. GLOBAL MODELS ARE IN \r\nAGREEMENT THAT INVEST 99S WILL CONTINUE TO RAPIDLY CONSOLIDATE AND \r\nTAKE A GENERAL SOUTH-SOUTHWESTWARD TRACK OVER THE NEXT 24 HOURS. \r\nMAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 28 KNOTS. \r\nMINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1000 MB. THE \r\nPOTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN \r\nTHE NEXT 24 HOURS IS UPGRADED TO MEDIUM.\r\n      (2) AN AREA OF CONVECTION (INVEST 90S) HAS PERSISTED NEAR 12.5S \r\n120.0E, APPROXIMATELY 350 NM NORTH-NORTHWEST OF BROOME, AUSTRALIA. \r\nANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS A BROAD AREA OF \r\nELONGATED ROTATION WITH FLARING CONVECTION TO THE NORTHEAST. STRONG \r\nWESTERLY FLOW ALONG 10S TO 11S LATITUDE IS HELPING INVEST 90S GAIN \r\nMORE MOMENTUM WITHIN THE NEXT 24-36 HOURS. A 310124Z PARTIAL METOP-B \r\nASCAT SCATTEROMETRY PASS REVEALS AN AREA OF 15-20 KNOT WINDS BEGINNING \r\nTO WRAP INTO THE WEAKLY DEFINED CIRCULATION CENTER. APPROXIMATELY \r\n100NM TO THE NORTH THERE IS A WIND FIELD OF STRONG 20-25 KNOT WINDS. \r\nENVIRONMENTAL ANALYSIS INDICATES THAT INVEST 90S IS IN A FAVORABLE \r\nENVIRONMENT FOR FURTHER DEVELOPMENT DUE TO VERY WARM (30-31C) SEA \r\nSURFACE TEMPERATURES, GOOD POLEWARD OUTFLOW ALOFT, AND LOW TO MODERATE \r\n(15 TO 20 KNOTS) VERTICAL WIND SHEAR. GLOBAL MODELS ARE IN GOOD \r\nAGREEMENT THAT INVEST 90S WILL QUICKLY CONSOLIDATE AND TRACK WEST-\r\nSOUTHWESTWARD OVER THE NEXT 24-36 HOURS. MAXIMUM SUSTAINED SURFACE \r\nWINDS ARE ESTIMATED AT 23 TO 28 KNOTS. MINIMUM SEA LEVEL PRESSURE IS \r\nESTIMATED TO BE NEAR 1003 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A \r\nSIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.\r\n      (3) NO OTHER SUSPECT AREAS.\r\n   C. SUBTROPICAL SYSTEM SUMMARY: NONE.\r\n3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 2.B.(1) TO MEDIUM \r\nAND ADDED LOW AREA IN PARA 2.B.(2).//"
