(1) THE AREA OF CONVECTION (INVEST 94B) PREVIOUSLY LOCATED NEAR 6.2N 87.1E, IS NOW LOCATED NEAR 5.5N 90.0E, APPROXIMATELY 542 NM EAST OF COLOMBO, SRI LANKA. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY AND A 111552Z ASCAT PASS SHOW A CONSOLIDATING LLC WITH SPARSE CONVECTION THAT IS ANTICIPATED TO BUILD AS THE SYSTEM APPROACHES CONVECTIVE MAXIMUM. UPPER-LEVEL ANALYSIS INDICATES MODERATE TO HIGH (15 TO 25 KNOTS) VWS THAT HAS IMPROVED OVER THE LAST 24HRS, BEING OFFSET BY ADEQUATE POLEWARD OUTFLOW. SEA SURFACE TEMPERATURES FROM 28C TO 30C ARE VERY FAVORABLE FOR FURTHER DEVELOPMENT OF THIS SYSTEM. GLOBAL MODELS ARE IN OVERALL GOOD AGREEMENT ON A NORTHWESTWARD TRACK AS THE SYSTEM DEVELOPS OVER THE NEXT FEW DAYS. SOME TRACK UNCERTAINTY EXISTS, WITH SOME MODELS SHOWING 94B REMAINING QUASI-STATIONARY FOR THE FIRST 6-12 HOURS OF THE MODEL RUN. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO MEDIUM.
