Looking at the sat and seeing that it's raining pretty well here, i'd hate to think what they are going to get in Vietnam. That looks like a large, slow moving disaster area heading their way. Hope they are getting ready.
It's interesting how the pattern this year has been to hold the line due west. Guess that's what caused the floods in Thailand.
But yeah, the outflow is feeding right into the monsoon and reacting with it and there seems to be a significant eddy of activity just to the east of us that's more evident in your pic than mine. Sure it will bob up again later.
