    2 PM (06 GMT) 04 SEPTEMBER: 17.8N 129.3E / 65-85 KPH (Tropical Storm) / NE @ 13 KPH
  • 2 AM (18 GMT) 05 SEPTEMBER: 18.7N 130.4E / 75-95 KPH (Tropical Storm) / NE @ 17 KPH
    2 AM (18 GMT) 06 SEPTEMBER: 21.7N 132.8E / 100-130 KPH (Tropical Storm) / NNE @ 15 KPH

    REMARKS: 2 AM (18 GMT) 04 SEPTEMBER POSITION: 17.2N 128.7E.
    ^TROPICAL STORM DUJUAN (13W) HAS SLOWLY TURNED TOWARD THE
    NORTHEAST OVER THE PAST SIX HOURS AS A NEAR-EQUATORIAL RIDGE
    EXTENSION BUILDS TO THE SOUTH AND EAST OF THE SYSTEM. THE INITIAL
    POSITION IS BASED ON RECENT PGTW AND RJTD POSITION FIXES. THE
    CURRENT INTENSITY OF 30 KNOTS IS CONSISTENT WITH REPORTING AGENCY
    DVORAK ESTIMATES RANGING FROM T=2.0 TO T=2.5 AND SCATTEROMETER DATA
    SHOWING APPROXIMATELY 30 KNOT WINDS NEAR THE TROPICAL CYCLONE
    CENTER. TD 13W IS SITUATED SOUTH AND WEST OF AN UPPER-LEVEL
    ANTICYCLONE CENTER IN AN AREA OF MODERATE EASTERLY VERTICAL WIND
    SHEAR. AS TD 13W TRACKS GRADUALLY NORTHEASTWARD UNDER THE STEERING
    INFLUENCE OF THE NEAR-EQUATORIAL RIDGE OVER THE NEXT 36 HOURS,
    VERTICAL WIND SHEAR IS EXPECTED TO PERSIST. THIS SHEAR SHOULD LIMIT
    THE INTENSIFICATION TO A SLOW RATE THROUGH THE FIRST 36 HOURS OF THE
    FORECAST PERIOD. AFTER TAU 36, THE INFLUENCE OF A BUILDING
    SUBTROPICAL RIDGE TO THE EAST WILL TURN TD 13W INCREASINGLY
    POLEWARD, WHILE DECREASING VERTICAL WIND SHEAR AND IMPROVED POLEWARD
    OUTFLOW WILL SUPPORT A HIGHER INTENSIFICATION RATE. BEYOND TAU 96,
    TD 13W WILL BEGIN TO TURN EASTWARD AHEAD OF A DEVELOPING MID-
    LATITUDE TROUGH. INCREASING WESTERLY SHEAR COULD LIMIT FURTHER
    INTENSIFICATION IN THE MEDIUM TO LONG RANGE, ALTHOUGH A MORE
    FAVORABLE OUTFLOW PATTERN COULD ALLOW THE TROPICAL CYCLONE TO
    INTENSIFY MORE THAN THE CURRENT FORECAST INDICATES....
