WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA): A. TROPICAL CYCLONE SUMMARY: NONE. B. TROPICAL DISTURBANCE SUMMARY: (1) AN AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 22.6N 179.8E IS NOW LOCATED NEAR 20.1N 179.3E, APPROXIMATELY 200 NM SOUTH- SOUTHWEST OF MIDWAY ATOLL. ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS A WELL DEVELOPED LOW LEVEL CIRCULATION CENTER (LLCC) WITH CENTRAL CONVECTION ALOFT, HOWEVER THIS SYSTEM CONTINUES TO APPEAR SUBTROPICAL. 2130Z MTSAT-IR DEPICTS AN INFLOW OF COLD-AIR STRATOCUMULUS FROM THE NORTH AND WEST. WATER VAPOR IMAGERY AND THE CIMMS TOTAL PRECIPITALBE WATER PRODUCT INDICATES COOL, DRY AIR CONTINUES TO WRAP AROUND THE WESTERN AND SOUTHERN PERIPHERY OF THE SYSTEM. MOVEMENT IS NOW EASTERLY AT APPROXIMATELY 7 KTS AND IS EXPECTED TO CONTINUE MOVING EAST TO NORTHEAST AROUND THE EDGE OF THE OF THE LOW- TO MID-LEVEL SUBTROPICAL RIDGE TO THE SOUTHEAST. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 45 TO 55 KNOTS BASED ON 2030Z PGTW DVORAK INTENSITIES AND 1828Z WINDSAT PRODUCT. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 990 MB. THE SYSTEM IS CURRENTLY ASSESSED AS SUBTROPICAL AND WILL BE CLOSELY MONITORED FOR POSSIBLE TRANSITION INTO A TROPICAL SYSTEM. BASED ON THE ABOVE ASSESSMENT THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS POOR. (2) NO OTHER SUSPECT AREAS. 2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST): A. TROPICAL CYCLONE SUMMARY: NONE. B. TROPICAL DISTURBANCE SUMMARY: NONE. 3.
