LLCC尚在,NRL上午復編,風場持續掃出20-25kts風力,JMA維持TD
      (1) AN AREA OF CONVECTION (REMNANTS 01W) PREVIOUSLY LOCATED NEAR
10.7N 151.4E IS NOW LOCATED NEAR 11.1N 151.6E, APPROXIMATELY 426 NM EAST-
SOUTHEAST OF GUAM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS A
BROAD, RAGGED, AND PARTLY-EXPOSED LOW-LEVEL CIRCULATION (LLC) WITH
DISORGANIZED CONVECTION SHEARED EASTWARD OF THE LLC. A 240335Z AMSR2
WINDSPEED IMAGE INDICATES A SMALL PATCH OF 18-KT PIXELS UNDER THE
CONVECTION AND 10-15KTS AROUND THE LLC. ENVIRONMENTAL ANALYSIS REVEALS
MARGINAL CONDITIONS WITH STRONG POLEWARD OUTFLOW, LOW (5-10KT) VWS OVER
THE LLC AND WARM (28-29C) SST OFFSET BY DRY AIR ENTRAINMENT AND STRONG
(25KT+) VWS JUST 30NM TO THE NORTH. GLOBAL MODELS ARE IN AGREEMENT THAT
THE SYSTEM WILL HAVE NO SIGNIFICANT DEVELOPMENT AS IT TRACKS WESTWARD
OVER THE NEXT 24-48 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED
AT 15 TO 20 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 REMAINS LOW.
