(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 6.2N 100.7E, IS NOW LOCATED NEAR 5.2N 101.3E, APPROXIMATELY 515 NM SOUTH OF BANGKOK, THAILAND. ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS CURVED, DEEP CONVECTIVE BANDING OVER THE SOUTHWEST QUADRANT OF THE CONSOLIDATING, EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC). A 050305Z METOP-B 89GHZ IMAGE DEPICTS FORMATIVE CONVECTIVE BANDING WRAPPING INTO A BROAD CENTER. A 050306Z ASCAT IMAGE SHOWS 15 TO 20 KNOT WINDS AROUND THE PERIPHERY OF THE CIRCULATION. UPPER LEVEL CONDITIONS ARE FAVORABLE WITH LOW VERTICAL WIND SHEAR (5-10KTS) AND GOOD POLEWARD OUTFLOW. HOWEVER, THE DISTURBANCE REMAINS POSITIONED OVER LAND, WHICH IS INHIBITING SIGNIFICANT DEVELOPMENT. GLOBAL MODELS INDICATE GRADUAL DEVELOPMENT OVER THE NEXT 24 TO 36 HOURS AS THE SYSTEM TRACKS NORTHEASTWARD TO NORTHWARD OVER THE GULF OF THAILAND ALONG THE EAST COAST OF THE MALAY PENINSULA. ONCE BACK OVER WATER IN ABOUT 12 HOURS, FAVORABLE SEA SURFACE TEMPERATURES (28-29C) SHOULD AID IN DEVELOPMENT. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO HIGH.
