Re: WPAC: INVEST 99W
the models are not anymore showing a moderate tropical storm or a typhoon out of this.... looks like this system is now properly initialized and saw the conditions nearby as not that conducive...
still a slow-tracker TD bears watching especially for low-lying areas...

I'm expecting a year crosser from this, like Soulik 2001. I also will not be surprised if there will be TS Jangmi by tomorrow; also not surprised if we see STS Jangmi before or on New Year's Day. 23W-to-be found a sweet spot of decreasing shear.

Well Lingling occurred in November and we are in the winter months where conditions are less favorable...It could happen but never say never in the WPAC
