Moderator: S2k Moderators
ECM develops this region in the Yellow Sea probably into a minimal TS from the looks of things.

JMA 18Z analysis:
TROPICAL DEPRESSION 1004 HPA AT 23N 130E NNW 15 KT.
Morning vis:
Many microwave passes, but all missed part of the system. If you combine these in your mind, perhaps better organized.
SAB Dvorak classification steady at T1.0:

RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY:
(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 21.6N
134.6E, IS NOW LOCATED NEAR 22.6N 131.4E, APPROXIMATELY 300 NM
SOUTHEAST OF OKINAWA, JAPAN. ANIMATED INFRARED SATELLITE IMAGERY AND
A 262044Z SSMIS MICROWAVE IMAGE SHOW CONTINUED FLARING CONVECTION
OVER A SLOWLY ORGANIZING LOW LEVEL CIRCULATION CENTER (LLCC). THE
LLCC IS IN AN AREA OF UPPER LEVEL DIVERGENCE, GOOD OUTFLOW, AND LOW
VERTICAL WIND SHEAR FAVORABLE FOR DEVELOPMENT. HOWEVER, THIS SYSTEM
HAS BEEN SLOW TO DEVELOP BECAUSE AN UPPER LEVEL LOW TO THE EAST IS
MOVING WESTWARD TOWARD THE LLCC CAUSING INCREASED IN THE EASTERN
PERIPHERY. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 MB.
DUE TO THE FAVORABLE UPPER LEVEL CONDITIONS, THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS REMAINS FAIR.

Here is the Radar for Okinawa....You can see the rain in the lower right moving on up. Lets hope it doesn't get to bad here before I get home....lol

If I may ask why do you rank the centers in this order? I'll admit I like JMA's interim updates of storm position between advisory times.
It's mainly due to the fact most of the typhoons I cover are either in Taiwan, Japan or near Hong Kong. All those agencies have good websites and I can easily blend all of their forecasts together to try and get into the best place. Sadly PAGASA in the Philippines have website issues when a typhoon is nearing (I guess due to increased traffic.)
JTWC tracks often shift left and right faster than a windscreen wiper however I do look at their forecasts and enjoy reading their prognostic reasonings.
Back on topic, looks like this TD will be racing against the SCS TD to get the next name on the list. The next names are Lionrock (a mountain in Hong Kong which I can actually see out of my window right now) and Kompasu (Japanese for compass which made direct hit on Hong Kong a few years ago.)

The cross is the current location so you can expect winds of 30kts gusting to 45kts. Winds at Kadena are only a modest 15mph from the ESE at the moment.

It is virtually passing over you, StormingB81. This system is poorly organized, which is why none of the other centers are declaring it a depression. ASCAT, although missing the center to the east, shows a very broad area of low pressure:
Most of the weather is located to the north and east of the center:
Development of this system will be very slow, as the JMA advisory above indicated. In short, what you're seeing now is basically it: scattered showers as the system passes by.
