if models are correct, it is not yet expected to develop into a TS within the next 48 hours. Let's see what it will do as it nears Luzon. VWS will be a problem here.

Using SSD satellite fixes, the LLCC remains very disorganized.

We have to wait further.

THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 11.2N, 143.2E,
IS NOW LOCATED NEAR 13.6N 140.7E APPROXIMATELY 245NM WEST OF ANDERSEN AFB,
GUAM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS A BROAD LOW LEVEL
CIRCULATION CENTER WITH FRAGMENTED CONVECTIVE BANDING FORMING ALONG THE
NORTHERN SEMI-CIRCLE. A 272231Z SSMIS MICROWAVE IMAGE DEPICTS A BROAD SYSTEM
WITH IMPROVING CONVECTIVE BANDING THAT HAS YET TO FULLY CONSOLIDATE. UPPER
LEVEL ANALYSIS INDICATES A FAVORABLE ENVIRONMENT WITH LOW (05 TO 10 KNOTS)
VERTICAL WIND SHEAR AND DIFFLUENT WESTERLY OUTFLOW. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE
IS ESTIMATED TO BE NEAR 100 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS MEDIUM.

Looks like the US Military has just now upgraded this to a TCFA. JMA still has it as a Tropical Depression.

Thinking it may track to and clip the top end of Philippines in the santa ana area and move across that line. As a moderate typhoon at best.
