SUBTROPICAL SYSTEM SUMMARY:","      (1) THE AREA OF CONVECTION (INVEST 91W) PREVIOUSLY LOCATED NEAR ","22.2N 120.2E IS NOW LOCATED NEAR 25.4N 123.1E, APPROXIMATELY 260 NM ","WEST-SOUTHWEST OF KADENA, JAPAN. THE SYSTEM IS CURRENTLY CLASSIFIED AS A ","SUBTROPICAL DEPRESSION, GENERALLY CHARACTERIZED AS HAVING BOTH TROPICAL ","AND MIDLATITUDE CYCLONE FEATURES. ANIMATED MULTISPECTRAL SATELLITE ","IMAGERY (MSI) DEPICTS A WEAK, DISORGANIZED ROTATION MOVING JUST SOUTH OF ","THE MAI-YU/BAIU BOUNDARY CURRENTLY DRAPED ACROSS THE EAST CHINA SEA. 91W ","IS FORECASTED TO CONTINUE MOVING RAPIDLY NORTH NORTH-EASTWARD INTO THE ","EAST CHINA SEA. ENVIRONMENTAL ANALYSIS FOR THE AREA INDICATES MARGINALLY ","FAVORABLE CONDITIONS FOR INTENSIFICATION WITH LOW VERTICAL WIND SHEAR ","(10-15 KNOTS), WARM (26-27 C) SEA SURFACE TEMPERATURES (SST), AND GOOD ","POLEWARD OUTFLOW ALOFT. THE SYSTEM TRANSITS NORTHEASTWARD IT WILL ","ENCOUNTER SIGNIFICANTLY COOLER SSTS SURROUNDING THE KUROSHIO CURRENT, AS ","WELL AS INCREASED TEMPERATURE ADVECTION. DETERMINISTIC GUIDANCE SHOWS ","91W REACHING PEAK INTENSITY OVER THE NEXT 18 HOURS AS IT PASSES WEST OF ","OKINAWA. THE WIND FIELD IS FORECAST TO EXPAND AS IT MOVES THROUGH THE ","EAST CHINA SEA, WITH THE HIGHEST WINDS BEING LOCATED IN THE EASTERN ","HEMISPHERE OF THE CIRCULATION. MAXIMUM SUSTAINED SURFACE WINDS ARE ","ESTIMATED AT 23 TO 28 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO ","BE NEAR 1002 MB.
