REF B IS A TROPICAL CYCLONE \r\nFORMATION ALERT.//\r\nRMKS/\r\n   B. TROPICAL DISTURBANCE SUMMARY:\r\n      (1) THE AREA OF CONVECTION (INVEST 90W) PREVIOUSLY LOCATED NEAR \r\n21.2N 127.6E IS NOW LOCATED NEAR 21.7N 127.1E, APPROXIMATELY 368 NM \r\nEAST-SOUTHEAST OF TAIPEI, TAIWAN. ANIMATED VISIBLE SATELLITE IMAGERY \r\nDEPICTS EXPOSED LOW LEVEL CLOUD LINES WRAPPING INTO A DEFINED \r\nCIRCULATION CENTER. CONVECTION IS FLARING IN THE SOUTHERN QUADRANT \r\nWITH ANVILS SHEARED TO THE SOUTH. A PARTIAL SCATTEROMETRY PASS SHOWS \r\nTHE SYSTEM IS FORMING ADJACENT TO AN EXTENSIVE BELT OF 20-30 KNOT \r\nSOUTHEASTERLY WINDS TO THE EAST OF THE CIRCULATION. DETERMINISTIC AND \r\nPROBABILISTIC MODELS DEPICT A DEEPENING SYSTEM FORMING BESIDE THE WIDE \r\nSWATH OF VIGOROUS LOW-LEVEL FLOW AND HEADING GENERALLY NORTHWESTWARD. \r\nGLOBAL MODELS INDICATE SLOW DEVELOPMENT; HOWEVER, THEY DO INDICATE A \r\nPOSSIBILITY FOR THE STRONGER WINDS TO THE EAST TO WRAP AROUND THE \r\nCIRCULATION. ENVIRONMENTAL CONDITIONS ARE MARGINALLY FAVORABLE WITH \r\nMODERATE EQUATORWARD OUTFLOW ALOFT, MODERATE TO HIGH (20-25 KNOTS) \r\nVERTICAL WIND SHEAR AND WARM (30-31 C) SEA SURFACE TEMPERATURES \r\nCREATING A CONDUCIVE AREA FOR FURTHER DEVELOPMENT MOVING FORWARD. \r\nMAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. \r\nMINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. THE \r\nPOTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN \r\nTHE NEXT 24 HOURS IS UPGRADED TO HIGH. SEE REF B (WTPN21 PGTW 200600) \r\nFOR FURTHER DETAILS.\r\n      (2) NO OTHER SUSPECT AREAS.\r\n   B. TROPICAL DISTURBANCE SUMMARY: NONE."
