JTWC評級Low

(1) AN AREA OF CONVECTION (INVEST 92W) HAS PERSISTED NEAR 10.2N
152.9E, APPROXIMATELY 510NM EAST-SOUTHEAST OF GUAM. ANIMATED
INFRARED SATELLITE IMAGERY, AND AN 85GHZ SSMI MICROWAVE IMAGE FROM
171701Z, SHOW AN EXPOSED, ELONGATED CIRCULATION WITH PATCHY
ASSOCIATED CONVECTION. UPPER LEVEL ANALYSIS INDICATES A MARGINALLY
FAVORABLE ENVIRONMENT WITH LOW TO MODERATE VERTICAL WIND SHEAR (5-15
KNOTS) AND MODERATE POLEWARD OUTFLOW ALOFT. SEA SURFACE TEMPERATURES
ARE FAVORABLE, BETWEEN 29 AND 30 DEGREES CELSIUS. MODELS SHOW
POSSIBLE TC FORMATION TO THE EAST OF LUZON IN APPROXIMATELY 3 TO 5
DAYS. 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.

JTWC評級Medium

(1) THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED NEAR 10.2N 152.9E, IS NOW LOCATED NEAR 11.0N 150.2E, APPROXIMATELY 348 NM EAST-SOUTHEAST OF ANDERSEN AFB, GUAM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 172319Z MHS METOP-A 89GHZ IMAGE DEPICT A SLOWLY CONSOLIDATING AND BROAD LOW LEVEL CIRCULATION (LLC). A 172310Z SCATSAT IMAGE DEPICTS AN ELONGATED CIRCULATION WITH CONVERGENT WESTERLY FLOW OVER THE SOUTHERN SEMI-CIRCLE. UPPER LEVEL ANALYSIS SHOWS A FAVORABLE ENVIRONMENT WITH LOW (5-10 KNOT) VERTICAL WIND SHEAR AND GOOD OUTFLOW, ESPECIALLY POLEWARD OUTFLOW WHICH IS ENHANCED BY A TUTT CELL LOCATED TO THE NORTHEAST. SEA SURFACE TEMPERATURES REMAIN FAVORABLE (28-30 CELSIUS) FOR FUTURE DEVELOPMENT. DYNAMIC MODELS INDICATE GRADUAL DEVELOPMENT THROUGH TAU 36, THEN MORE RAPID DEVELOPMENT AFTER THE SYSTEM TRACKS WEST OF GUAM. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO MEDIUM.
