JTWC評級LOW

AN AREA OF CONVECTION HAS PERSISTED NEAR 33.5N 154.0E,
APPROXIMATELY 775 NM EAST OF TOKYO, JAPAN. ANIMATED ENHANCED INFRARED
SATELLITE IMAGERY DEPICTS AN ELONGATED LOW LEVEL CIRCULATION CENTER
HAS BEEN QUICKLY PROGRESSING TO THE EAST-NORTHEAST WITH AN UPPER
LEVEL ANTICYCLONE LOCATED OVER THE SYSTEM. PERSISTENT DEEP CONVECTION
HAS BEEN LOCATED ON THE SOUTHEASTERN PERIPHERY OF THE AREA. SEA
SURFACE TEMPERATURES ARE IN A MARGINALLY FAVORABLE ENVIRONMENT. A
RECENT 251107Z ASCAT PASS SHOWED SOME 15 TO 20 KNOT WINDS ALONG THE
SOUTHEASTERN QUADRANT. MODEL GUIDANCE INDICATES A WEAKENING OF THE
CIRCULATION AS IT BEGINS TO MOVE MORE NORTHWARD. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1010 MB. BASED ON THE ELONGATED
SURFACE LOW TRACKING QUICKLY INTO A LESS FAVORABLE ENVIRONMENT, AND
A LACK OF MODEL DEVELOPMENT, THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.

JMA維持溫帶氣旋

風場掃描風速 30 到 35 節，只要 JMA 承認這是熱帶氣旋就可以直接命名了。
