    ^TS 16W HAS TRACKED WESTWARD UNDER THE INFLUENCE OF THE MID-
    LEVEL SUBTROPICAL STEERING RIDGE TO THE NORTH OVER THE PAST 12
    HOURS. ANIMATED MULTI-SPECTRAL IMAGERY SHOWS MULTIPLE CONVECTIVE
    BANDS CONSOLIDATING TIGHTLY ABOUT A PARTIALLY-EXPOSED LOW LEVEL
    CIRCULATION CENTER (LLCC). HOWEVER, THE IMAGERY ALSO SHOWS THAT THE
    DEEP CONVECTION IS CONFINED TO THE SOUTHERN SEMI-CIRCLE OF THE
    SYSTEM, INDICATING THAT KOPPU IS IN AN AREA OF MODERATE VERTICAL
    WIND SHEAR. UPPER-LEVEL ANALYSIS DOES INDEED SHOW THAT AN UPPER-
    LEVEL ANTICYCLONE TO THE NORTH IS PRODUCING NORTHEASTERLY FLOW
    THROUGH THE SOUTH CHINA SEA. WATER VAPOR IMAGERY DOES CONTINUE TO
    INDICATE THAT THE SYSTEM HAS STRONG EQUATORWARD OUTFLOW, ENABLING
    THE SYSTEM TO CONSOLIDATE AND INTENSIFY TO TROPICAL STORM
    STRENGTH...
