提升Medium (2) THE AREA OF CONVECTION (INVEST 96W) PREVIOUSLY LOCATED NEAR 6.2N 152.3E, IS NOW LOCATED NEAR 6.5N 152.9E, APPROXIMATELY 79 NM SOUTH-SOUTHEAST OF CHUUK. ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS PERSISTENT DEEP CONVECTION BEGINNING TO ORGANIZE AROUND A BROAD LOW LEVEL CIRCULATION CENTER (LLCC). A 072322Z 89GHZ AMSU IMAGE DEPICTS THE MAJORITY OF THE CONVECTIVE BANDING OVER THE SOUTHERN QUADRANT OF THE LLCC. UPPER LEVEL ANALYSIS INDICATES A FAVORABLE ENVIRONMENT WITH LOW VERTICAL WIND SHEAR (10 TO 15 KNOTS) AND MODERATE DIFFLUENCE ALOFT, WITH FAVORABLE SEA SURFACE TEMPERATURES (30-32 CELSIUS). GLOBAL MODELS SHOW SLOW DEVELOPMENT AND A WEST-NORTHWESTARD TRACK. 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 UPGRADED TO MEDIUM. |
最新評估是Low "(2) AN AREA OF CONVECTION (INVEST 96W) HAS PERSISTED NEAR 6.2N 153.0E, APPROXIMATELY 95 NM SOUTHEAST OF CHUUK. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY SHOWS PERSISTENT, BUT DISORGANIZED DEEP CONVECTION ASSOCIATED WITH A BROAD LOW LEVEL CIRCULATION CENTER (LLCC). A 071131Z METOP-A 89GHZ IMAGE SHOWS WEAK CONVECTIVE BANDING OVER THE EASTERN QUADRANT OF THE LLCC. A 071131Z ASCAT IMAGE DEPICTS AN ELONGATED CIRCULATION WITH 10 TO 15 KNOT WINDS OVER THE NORTHERN SEMI-CIRCLE AND 15 TO 20 KNOT WESTERLY WINDS OVER THE SOUTHERN PERIPHERY. UPPER LEVEL ANALYSIS INDICATES A FAVORABLE ENVIRONMENT WITH LOW VERTICAL WIND SHEAR 10 TO 15 KNOTS AND STRONG DIFFLUENCE ALOFT ASSOCIATED WITH A POINT SOURCE. GLOBAL MODELS SHOW SLOW DEVELOPMENT AND A WEST-NORTHWESTARD TRACK. 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." |
