REF B IS A TROPICAL \r\nCYCLONE WARNING.//\r\nRMKS/\r\n   B. TROPICAL DISTURBANCE SUMMARY:\r\n      (1) AN AREA OF CONVECTION (INVEST 90W) HAS PERSISTED NEAR 20.1N \r\n129.0E, APPROXIMATELY 507 NM SOUTHEAST OF TAIPEI, TAIWAN. ANIMATED \r\nENHANCED INFRARED SATELLITE IMAGERY DEPICTS FORMATIVE BANDING OVER THE \r\nSOUTHERN AND EASTERN QUADRANTS OF AN ELONGATED LOW-LEVEL CIRCULATION \r\nCENTER (LLCC). A 191250Z MHS 89 GHZ MICROWAVE IMAGE REVEALS A WEAKLY \r\nDEFINED CENTER, WITH THE CONVECTION PRIMARILY OVER THE EASTERN \r\nSEMICIRCLE. A RECENT PARTIAL SCATTEROMETER IMAGE SHOWS SHARP CYCLONIC \r\nTURNING AND A POSSIBLE ELONGATED CIRCULATION ADJACENT TO AN EXTENSIVE \r\nSWATH OF 20-30 KNOT SOUTHERLY WINDS, WHICH COULD BE AIDING IN THE \r\nDISTURBANCE'S SPIN-UP. ENVIRONMENTAL CONDITIONS ARE MARGINALLY \r\nFAVORABLE WITH LOW TO MODERATE (15 TO 20 KNOTS) VERTICAL WIND SHEAR \r\nOFFSET BY BROAD DIFFLUENCE ALOFT. GFS IS THE MOST AGGRESSIVE MODEL AT \r\nTHIS TIME INDICATING A WEST-NORTHWESTWARD TRACK TOWARD TAIWAN, WITH \r\nSTEADY DEVELOPMENT OVER THE NEXT 36 HOURS. MAXIMUM SUSTAINED SURFACE \r\nWINDS ARE ESTIMATED AT 12 TO 18 KNOTS. MINIMUM SEA LEVEL PRESSURE IS \r\nESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A \r\nSIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.\r\n      (2) NO OTHER SUSPECT AREAS.\r\n   B. TROPICAL DISTURBANCE SUMMARY: NONE."
