SUBTROPICAL SYSTEM SUMMARY:","      (1) AN AREA OF CONVECTION (INVEST 98W) HAS PERSISTED NEAR 20.7N ","130.6E, APPROXIMATELY 372 NM SOUTH-SOUTHEAST OF KADENA. THE SYSTEM IS ","CURRENTLY CLASSIFIED AS A SUBTROPICAL DISTURBANCE, GENERALLY ","CHARACTERIZED AS HAVING BOTH TROPICAL AND MIDLATITUDE CYCLONE FEATURES. ","ENHANCED INFRARED IMAGERY DEPICTS AN ILL-DEFINED LOW-LEVEL CIRCULATION ","PARTIALLY OBSCURED BY FLARING CONVECTION IN THE NORTHEAST QUADRANT AND ","SITUATED UNDER AN UPPER LEVEL LONG WAVE TROUGH. THE 170030Z ASCAT-B AND ","171330Z OSCAT-3 PASSES REVEALED AN ASYMMETRIC WIND FIELD WITH 20-25 KNOT ","WINDS ON THE NORTHERN PERIPHERY OF THE DISTURBANCE. ENVIRONMENTAL ","ANALYSIS DEPICTS HIGH VERTICAL WIND SHEAR (25 TO 35KTS), WARM SEA ","SURFACE TEMPERATURES (28 TO 29 C) AND MODERATE POLEWARD UPPER LEVEL ","OUTFLOW AND DIVERGENCE. MODELS KEEP 98W UNDER THE TROUGH OVER THE NEXT ","24-36 HOURS, AFTER WHICH TIME A STRONG RIDGE WILL BUILD IN FROM THE WEST ","AND INTRODUCE HIGH VERTICAL WIND SHEAR, AND VERY DRY AIR WILL ENVELOPE ","THE CIRCULATION. WHILE THE DISTURBANCE WILL REGAIN TROPICAL ","CHARACTERISTICS, THE DISTURBANCE IS UNLIKELY TO DEVELOP INTO A TROPICAL ","CYCLONE AS A RESULT OF THESE FACTORS OVER THE NEXT 36-48 HOURS.   ","MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 28 KNOTS. MINIMUM ","SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR ","THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 ","HOURS IS LOW.","      (2) NO OTHER SUBTROPICAL SYSTEMS.","   B.
