97.9E, APPROXIMATELY 85 NM NORTH-NORTHWEST OF PHUKET, THAILAND.
ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A BROAD LOW-LEVEL

THE ANDAMAN SEA AND 15-20 KNOT EASTERLIES OVER THE GULF OF THAILAND.
UPPER-LEVEL CONDITIONS ARE MARGINALLY FAVORABLE WITH MODERATE
EASTERLY VERTICAL WIND SHEAR OFFSET BY BROAD DIFFLUENCE ALOFT.
GLOBAL MODELS INDICATE STEADY DEVELOPMENT AS THE SYSTEM TRACKS OVER
THE ANDAMAN SEA, AWAY FROM LAND, AND TOWARD THE ANDAMAN ISLANDS OVER
THE NEXT 1 TO 2 DAYS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED
AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE
NEAR 1007 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT
