模式分析出這隻系統應該是具有熱帶性質
JMA應該只是單純標註為低壓區，而非溫帶低壓

JMA已標註為溫帶低壓

LOW 998 HPA AT 23N 123E ENE 10 KT.

JTWC持續判定為副熱帶低壓

反而比較注意廣東近海那邊的渦漩...比較具威脅

(2) AN AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED NEAR
20.2N 116.5E, IS NOW LOCATED NEAR 20.5N 118.1E, APPROXIMATELY 725 NM
WEST-SOUTHWEST OF KADENA AB. ANIMATED ENHANCED INFRARED SATELLITE
IMAGERY SHOWS DISORGANIZED, FLARING CONVECTION AND A 1201026Z SSMIS
91GHZ MICROWAVE IMAGE REVEALS THE DEEPEST CONVECTION LOCATED SOUTH
OF THE FORECASTED LOW LEVEL CIRCULATION CENTER. THE EXACT LOCATION
OF THE CIRCULATION CENTER IS STILL UNCERTAIN. INVEST 93W IS LOCATED
IN AN AREA HIGHLY FAVORABLE FOR DEVELOPMENT WITH LOW VERTICAL WIND
SHEAR (5-10 KTS), DUAL OUTFLOW CHANNELS, AND WARM SSTS (28-29C).
GLOBAL MODELS STRONGLY AGREE THIS SYSTEM WILL MEET WARNING CRITERIA
WITHIN THE NEXT 24-36 HOURS. MODELS INDICATE THE SYSTEM WILL TRACK
NORTHEASTWARD TOWARDS OKINAWA BEFORE MAKING A SLIGHT TURN TO TRACK
JUST EAST OF MAINLAND JAPAN. MAXIMUM SUSTAINED SURFACE WINDS ARE
ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED
TO BE NEAR 1001 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO
MEDIUM.
