Scatterometer data indicates it is at least a TD and quite possibly a TS now. Meteo France ad BoM are basically saying no development likely. Better check again...

Recent scatterometer pass says it's a TS. Jakarta, official agency of the region, says a 20-40% chance of development. I have it a TS in our advisory.

I am in no way a professional. Take what I say with a grain of salt as I could be totally wrong. Please refer to the NHC, NWS, or SPC for official information.

BoM requires 34+ kt winds to extend more than half way around the center for naming. In an email from someone there, they said it was borderline, right at 50%.
