12z ECMWF and EPS have uptrended on TC activity following #Yinxing. However, this uptick partially coincides with CCKW passage when numerical guidance historically tends to be to be aggressive in the medium range, including even the ECMWF.
Newly named Tropical Storm #Yinxing has a classical well defined curved band signature evident on IR alongside a central sense overcast with -80C cloud tops that is often a precursor for significant intensification.
Low level convergence associated with Invest #90W has increased, yielding an increase in central convection. Both major global models and their ensembles have significantly uptrended today and a typhoon in the vicinity of Luzon is a possibility later this week.
An unusually strong MJO for a weak but EP La Niña year has aided, in addition to #Kong-rey, cyclonic vorticity across the tropical Pacific and a westward extension of the monsoon trough. A tropical disturbance (Invest #92E) has sustained organized convection as far west as ~128W.
