JTWC評級Low
AN AREA OF CONVECTION HAS PERSISTED NEAR 11.7N 151.1E,
APPROXIMATELY 385 NM EAST-SOUTHEAST OF GUAM. ANIMATED ENHANCED
INFRARED SATELLITE IMAGERY DEPICTS A LARGE AREA OF DEEP CONVECTION
ASSOCIATED WITH AN ILL-DEFINED LOW-LEVEL CIRCULATION CENTER. A
211143Z METOP-A MICROWAVE IMAGE REVEALS FRAGMENTED CONVECTIVE
BANDING OVER THE NORTHEASTERN AND SOUTHWESTERN QUADRANTS BROADLY
WRAPPING TOWARDS THE CENTER. A 211055Z ASCAT PASS SHOWS A WEAK (05
TO 10 KNOT) ELONGATED CIRCULATION WITH STRONGER (20 TO 25 KNOT)
SOUTHWESTERLY WINDS WELL SOUTH OF THE CENTER. UPPER-LEVEL ANALYSIS
INDICATES THE DISTURBANCE IS LOCATED IN A FAVORABLE ENVIRONMENT WITH
LOW TO MODERATE VERTICAL WIND SHEAR AND GOOD OUTFLOW. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR
THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS LOW.
