THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 10.3N
145.0E, IS NOW LOCATED NEAR 11.2N 146.2E, APPROXIMATELY 160 NM
SOUTHEAST OF ANDERSEN AFB, GUAM. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS AN ILL-DEFINED LOW LEVEL CIRCULATION CENTER (LLCC)
WITH FLARING DEEP CONVECTION ALONG THE SOUTHEASTERN QUADRANT WHILE A
DEFINED MID-LEVEL CIRCULATION HAS PERSISTED TO THE SOUTH. A 262240Z
SSMIS MICROWAVE IMAGE ADDITIONALLY SHOWS THE LLCC IS POORLY DEFINED
WHILE THE DEEP CONVECTION IS CONFINED TO THE SOUTH. UPPER-
LEVEL ANALYSIS INDICATES A FAVORABLE ENVIRONMENT WITH LOW (05 TO 10
KNOTS) VERTICAL WIND SHEAR AND EXCELLENT POLEWARD AND EQUATORWARD
OUTFLOW. SEA SURFACE TEMPERATURES IN THE REGION ARE CONDUCIVE (29 TO
30 DEGREES CELSIUS) FOR DEVELOPMENT. MAXIMUM SUSTAINED SURFACE WINDS
ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1005 MB. DUE TO THE FAVORABLE ENVIRONMENT, THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS HIGH.
