ANIMATED MULTISPECTRAL SATELLITE ","IMAGERY (MSI) DEPICTS A POORLY DEFINED LOW-LEVEL CIRCULATION WITH ","FLARING CONVECTION IN THE NORTHERN AND WESTERN PERIPHERIES. A 150217Z ","METOP-C ASCAT PASS REVEALED A BROAD LOW LEVEL CIRCULATION WITH 10-15 ","KT WINDS WRAPPING FROM THE NORTHERN PORTION OF THE SYSTEM. ","ENVIRONMENTAL ANALYSIS INDICATES MARGINALLY FAVORABLE CONDITIONS FOR ","DEVELOPMENT WITH LOW VERTICAL WIND SHEAR (5-10 KTS), AND WARM (29-30 ","C) SEA SURFACE TEMPERATURES, OFFSET BY WEAK EQUATORWARD OUTFLOW ALOFT ","AND THE BROAD NATURE OF THE WIND FIELD. GLOBAL DETERMINISTIC MODELS ","ARE IN AGREEMENT THAT 98W WILL PROPAGATE NORTHWESTWARD THROUGH THE ","SOUTH CHINA SEA WITH LITTLE DEVELOPMENT. ENSEMBLE MODELS ARE ALSO IN ","AGREEMENT ON A NORTHWESTWARD TRACK OVER THE NEXT 24 HOURS WITH ECENS ","BEING MORE AGGRESSIVE WITH THE INTENSITY OF THE SYSTEM. MAXIMUM ","SUSTAINED SURFACE WINDS ARE ESTIMATED AT 13 TO 18 KNOTS. MINIMUM SEA ","LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB.
