升格評級為MEDIUMTHE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 8.5N 151.5E, IS NOW LOCATED NEAR 8.7N 150.2E, APPROXIMATELY 120 NM NORTHWEST OF CHUUK, FSM. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY SHOWS THE SYSTEM HAS FURTHER DEEPENED AND CONSOLIDATED OVER THE PAST 24 HOURS. A 011137Z SCATTEROMETRY PASS DEPICTS A WELL-DEFINED AND SYMMETRICAL LOW LEVEL CIRCULATION CENTER WITH UP TO 20-KNOT WIND BARBS FEEDING IN FROM THE SOUTHERN FLANK. UPPER-LEVEL ANALYSIS INDICATES THE SYSTEM IS LOCATED IN AN AREA OF LIGHT TO MODERATE (10 TO 15 KNOT) VERTICAL WIND SHEAR AND EXCELLENT DUAL OUTFLOW CHANNELS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. IN VIEW OF THE IMPROVED UPPER LEVEL ENVIRONMENT, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO MEDIUM.
