AN AREA OF CONVECTION HAS PERSISTED NEAR 13.6N 110.5E,
APPROXIMATELY 235 NM SOUTHEAST OF HUE, VIETNAM. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY REVEALS AN EXPOSED LLCC THAT IS
EMBEDDED WITHIN A BROAD AREA OF TROUGHING THAT SPANS ACROSS THE
SOUTH CHINA SEA. A 020234Z ASCAT REVEALS A POORLY DEFINED LLCC WITH
10 TO 15 KNOT WINDS NEAR THE CENTER AND SOME STRONGER (15 TO 20
KNOTS) IN THE OUTER PERIPHERIES OF THE TROUGHING. UPPER-LEVEL
ANALYSIS REVEALS A MARGINAL ENVIRONMENT WITH BROADLY DIFFLUENT
EASTERLY OUTFLOW WHICH IS BEING OFFSET BY MODERATE VERTICAL WIND
SHEAR. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1010 MB.
THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS LOW.
