REMARKS: 8 AM (00 GMT) 16 SEPTEMBER POSITION: 20.1N 131.3E.
^TROPICAL STORM (TS) WIPHA HAS BEEN SLOW TO ORGANIZE, DUE TO A
SMALL TUTT CELL TO ITS NORTH WHICH HAS SUPPRESSED CONVECTION
OVER THE NORTHERN SEMI-CIRCLE OF THE LOW LEVEL CIRCULATION CENTER
(LLCC). THE STORM HAS BEEN SLOWLY TRACKING WESTWARD AS IT CONTINUES
TO CONSOLIDATE. AN UPPER LEVEL ANTICYCLONE TO THE EAST OF THE SYSTEM
IS PROVIDING EXCELLENT EQUATORWARD OUTFLOW
