^ANIMATED INFRARED IMAGERY DEPICTS A SYSTEM WITH A WELL DEFINED CENTER
AND DEEP CONVECTION ALONG THE SOUTHEASTERN EDGE OF A FORMATIVE EYE-LIKE
FEATURE. A 141128Z SSMIS PASS SHOWS DEEP CONVECTIVE BANDS WRAPPING
AROUND THE SOUTHERN AND EASTERN PERIPHERY OF THE SYSTEM AND INTO THE
CENTER. THE SSMIS PASS SHOWS AN EYE-FEATURE OPEN TO THE NORTHWEST,
ALONG WITH A SIGNIFICANT LACK OF CONVECTION TO THE NORTHWEST OF THE
SYSTEM, POSSIBLY BECAUSE OF DISRUPTION OF THE SURFACE FLOW DUE TO
PROXIMITY TO LAND. THE SYSTEM IS IN A REGION OF FAVORABLE SEA
SURFACE TEMPERATURES, MODERATE (20 KTS) VERTICAL WIND SHEAR AND HAS
FAVORABLE UPPER-LEVEL OUTFLOW TO THE WEST AND SOUTHWEST. HOWEVER,
THE SYSTEM IS TRACKING INTO SOUTHERN CHINA UNDER THE INFLUENCE OF
THE LOW- TO MID-LEVEL SUBTROPICAL RIDGE TO THE NORTH AND WILL
RAPIDLY WEAKEN AFTER IT MAKES LANDFALL IN THE NEXT 6 HOURS..(more)

>> KOPPU, meaning: Crater; Cup. Name contributed by: Japan.
