99.0E, APPROXIMATELY 114 NM SOUTH OF PHUKET, THAILAND. ANIMATED ENHANCED 
INFRARED SATELLITE IMAGERY DEPICTS DISORGANIZED DEEP CONVECTION FLARING 
OVER THE NORTHERN AND WESTERN QUADRANTS OF A BROAD LOW-LEVEL CIRCULATION

FORMATIVE SHALLOW BANDING OVER THE NORTHWESTERN SEMICIRCLE WITH A WEAKLY 
DEFINED LLC. UPPER-LEVEL ANALYSIS INDICATES A MARGINALLY FAVORABLE 
ENVIRONMENT WITH STRONG DIFFLUENCE OFFSET BY MODERATE (20 KNOTS) EASTERLY 
VERTICAL WIND SHEAR. SEA SURFACE TEMPERATURES OF 29C ARE CONDUCIVE FOR 
DEVELOPMENT. GLOBAL MODELS INDICATE STEADY DEVELOPMENT OVER THE NEXT TWO 
DAYS AS THE SYSTEM TRACKS WEST-NORTHWESTWARD. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 1005 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
