SOUTHEAST OF KYOTO, JAPAN, HAS TRACKED WEST-NORTHWESTWARD AT 07
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY (MSI) SHOWS A BROAD, EXPOSED LOW LEVEL CIRCULATION CENTER
(LLCC) WITH CURVED CONVECTIVE BANDS WRAPPING INTO THE SOUTHERN AND
EASTERN HALVES OF THE SYSTEM. A 30/2239Z TRMM IMAGE ALSO SHOWS THESE
BANDS OF CONVECTION WRAPPING INTO THE OUTER PERIPHERY OF THE LLCC.
INITIAL POSITION IS BASED ON THE AFOREMENTIONED MSI AND MICROWAVE
IMAGERY WITH FAIR CONFIDENCE. THE INITIAL INTENSITY IS BASED ON
PGTW, KNES, AND RJTD DVORAK CURRENT INTENSITY ESTIMATES OF 55 KNOTS.
A 31/0141Z ASCAT PASS PARTIALLY DEPICTS THE EXPANSIVE WIND RADII. TS
15W IS LOCATED BENEATH AN UPPER LEVEL LOW, WHICH HAS SUPPRESSED
CENTRAL CONVECTIVE DEVELOPMENT FOR SEVERAL DAYS. ANIMATED WATER
VAPOR IMAGERY SHOWS OUTFLOW HAS SLIGHTLY DECREASED TO THE WEST OF
TS 15W, AND THIS HAS RESULTED IN DECREASING CONVECTION IN THE
NORTHWEST QUADRANT OF THE SYSTEM. TS 15W IS CURRENTLY TRACKING ALONG
THE SOUTHWESTERN EXTENT OF A BUILDING SUBTROPICAL RIDGE (STR) TO THE
