JTWC (US NAVY & AIR FORCE) REMARKS:

REMARKS (for Meteorologists): 2 PM (06 GMT) SUN 11 SEPTEMBER POSITION: 21.0N 136.7E.
*THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 20.7N
137.9E, IS NOW LOCATED NEAR 21.0N 136.7E, APPROXIMATELY 350 NM
SOUTHWEST OF IWO TO. ANIMATED INFRARED SATELLITE IMAGERY CONTINUES
TO DEPICT A LARGE MONSOON DEPRESSION WITH DISORGANIZED DEEP
CONVECTION FLARING AROUND THE PERIPHERY. HOWEVER, A 101616Z AMSR-E
IMAGE INDICATES THAT A WELL-DEFINED LOW-LEVEL CIRCULATION CENTER IS
SLOWLY CONSOLIDATING WITHIN THE LARGER CIRCULATION WITH IMPROVED LOW-
LEVEL BANDING EVIDENT, PARTICULARLY OVER THE SOUTHERN SEMI-CIRCLE. A
101448Z OCEANSAT IMAGE SHOWS 15-20 KNOT WINDS NEAR THE CENTER WITH
STRONGER WINDS ALONG THE NORTHERN PERIPHERY OF THE MONSOON
DEPRESSION. THE UPPER-LEVEL ENVIRONMENT IS FAVORABLE FOR FURTHER
DEVELOPMENT WITH WEAK VERTICAL WIND SHEAR AND GOOD POLEWARD AND
EQUATORWARD OUTFLOW. 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 HIGH...(
