      (1) THE AREA OF CONVECTION (INVEST 99W) PREVIOUSLY LOCATED NEAR 
11.8N 148.6E IS NOW LOCATED NEAR 12.8N 147.5E, APPROXIMATELY 169 NM 
EAST OF GUAM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 050324Z

FAVORABLE ENVIRONMENT FOR DEVELOPMENT, WITH WARM (29-30C) SEA SURFACE 
TEMPERATURES, GOOD EQUATORWARD DIVERGENCE ALOFT, AND LOW (5-10KTS) 
VERTICAL WIND SHEAR. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT INVEST 
99W WILL GENERALLY TRACK NORTH-NORTHWESTWARD OVER THE NEXT 48 HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. 
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN
