JTWC下午評級Low
B. TROPICAL DISTURBANCE SUMMARY:
(1) AN AREA OF CONVECTION HAS PERSISTED NEAR 7.5N 131.0E,
APPROXIMATELY 340 NM WEST OF KOROR, PALAU. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY DEPICTS A WEAK BUT CONSOLIDATING LOW LEVEL
CIRCULATION CENTER (LLCC) WITH LIMITED CONVECTION ALONG THE NORTHERN
FLANKS. A 270126Z ASCAT PASS REVEALED A BROAD LLCC WITH ENHANCED
EASTERLIES ALONG THE NORTHERN PERIPHERY. UPPER-LEVEL ANALYSIS
REVEALS AN OVERALL FAVORABLE ENVIRONMENT WITH FAIR POLEWARD OUTFLOW
AND LOW TO MODERATE VERTICAL WIND SHEAR. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1008 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.

整體已有初步螺旋性
只不過逐步逼近民答那峨
發展還有待觀望
