"ABIO10 PGTW 121800\r\nMSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//\r\nSUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE INDIAN OCEAN/121800Z-\r\n131800ZFEB2024//\r\nRMKS/\r\n1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA):\r\n   A. TROPICAL CYCLONE SUMMARY: NONE.\r\n   B. TROPICAL DISTURBANCE SUMMARY: NONE.\r\n   C. SUBTROPICAL SYSTEM SUMMARY: NONE.\r\n2. SOUTH INDIAN OCEAN AREA (135E WEST TO COAST OF AFRICA):\r\n   A. TROPICAL CYCLONE SUMMARY: NONE.\r\n   B. TROPICAL DISTURBANCE SUMMARY:\r\n      (1) AN AREA OF CONVECTION (INVEST 90S) HAS PERSISTED NEAR 13.4S \r\n66.8E, APPROXIMATELY 492 NM SOUTHWEST OF DIEGO GARCIA. ANIMATED \r\nMULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS A SLOWLY CONSOLIDATING LOW \r\nLEVEL CIRCULATION (LLC) WITH DEEP CONVECTION ON THE EASTERN PERIPHERY OF \r\nTHE SYSTEM. DESPITE A FAIRLY WEAK 850MB VORTICITY SIGNATURE, \r\nENVIRONMENTAL ANALYSIS REVEALS FAVORABLE CONDITIONS FOR FURTHER \r\nDEVELOPMENT OF INVEST 90S WITH GOOD POLEWARD OUTFLOW ALOFT, LOW (10-\r\n15KT) VWS, AND WARM (29-30 C) SST. GLOBAL MODELS ARE IN GENERAL \r\nAGREEMENT THAT 90S WILL CONTINUE ON AN EASTWARD TRACK THROUGH THE \r\nSUBSIDENT ENVIRONMENT TO FINALLY GET MORE OF A CHIMNEY EFFECT GOING IN \r\nITS FAVOR BEYOND TAU 72, AND CONSOLIDATE AND STRENGTHEN MORE. MAXIMUM \r\nSUSTAINED SURFACE WINDS ARE ESTIMATED AT 14 TO 17 KNOTS. MINIMUM SEA \r\nLEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR THE \r\nDEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS \r\nIS LOW.\r\n      (2) NO OTHER SUSPECT AREAS.\r\n   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//\r\nNNNN\n"
