相比隔壁一直較看好90W的GFS,EC12Z無論系集或決定報,更為看好99W發展將壓過90W
就看接下來幾天的發展結果吧

JTWC06Z評級提升至Medium
(2) THE AREA OF CONVECTION (INVEST 99W) PREVIOUSLY LOCATED
NEAR 5.1N 142.3E IS NOW LOCATED NEAR 6.8N 135.7E, APPROXIMATELY 74
NM EAST-SOUTHEAST OF REPUBLIC OF PALAU. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY DEPICTS CONVECTIVE BANDING WRAPPING INTO A LOW
LEVEL CIRCULATION CENTER (LLCC). ANALYSIS INDICATES A MARGINALLY
FAVORABLE ENVIRONMENT FOR DEVELOPMENT CHARACTERIZED BY WARM (30-31C)
SEA SURFACE TEMPERATURES, AND LOW (<15 KTS) VWS OFFSET BY MINIMAL
OUTFLOW ALOFT. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT INVEST 99W
WILL CONTINUE TO TRACK WEST-NORTHWESTWARD AS IT CONSOLIDATES AND
STRENGTHENS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO
20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006
MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL
CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO MEDIUM.
