    REMARKS: 2 AM (06 GMT) 17 JULY POSITION: 19.5N 122.5E.
    ^TS 07W CONTINUES TRACKING ALONG THE SOUTHWESTERN PERIPHERY OF AN
    EXTENSION OF THE SUBTROPICAL RIDGE, LOCATED TO THE NORTHEAST OF TS
    07W. MULTISPECTRAL IMAGERY INDICATES THAT THE LOW LEVEL CIRCULATION
    CENTER (LLCC) HAS QUICKLY BECOME ORGANIZED WITH TIGHTLY CURVED
    BANDING DEVELOPING TOWARD THE LLCC. AS  TS 07W TRACKS TO THE NORTH
    OF LUZON, THE INFLOW OF RELATIVELY DRIER AIR (APPARENT IN TOTAL PRECI-
    PITABLE WATER PRODUCTS) HAS LED TO A DECREASE IN DEEP CONVECTION ON
    THE SOUTHEASTERN PERIPHERY. HOWEVER, THIS HAS BEEN OFFSET BY IN-
    CREASED DEEP CONVECTION ON THE NORTHERN PERIPHERY. UPPER LEVEL
    ANALYSIS STILL INDICATES STRONG EQUATORWARD OUTFLOW IS PRESENT.
    SEA SURFACE TEMPERATURES ARE FAVORABLE FOR DEVELOPMENT, AND THE
    OCEAN HEAT CONTENT (OHC) PRODUCTS INDICATE THERE IS A LARGE REGION
    OF DEEP, WARM WATER BETWEEN LUZON AND TAIWAN HELPING TO FUEL A BRIEF
    PERIOD OF RAPID DEVELOPMENT. HOWEVER, THE OHC WILL DECREASE AS TS
    07W TRACKS INTO THE NORTHERN PORTION OF THE SOUTH CHINA SEA AND
    IN ASSOCIATION WITH INCREASED VERTICAL WIND SHEAR WILL BEGIN TO
    WEAKEN. TS 07W IS FORECAST TO MAKE LANDFALL AROUND 36 HOURS AND
    QUICKLY BEGIN TO DISSIPATE, WITH FULL DISSIPATION BY 72 HOURS....
