Attn: Derek, AirForcemet, etc. : What is THAT?

Bump -- well, at this rate, one way or another, I guess we'll find out what it is... even if it's just by watching it!

Orographic lifting from a Jeanne rainband over PR, combined with Shear out of the N at the upper levels. Really they are just intense thundershowers produced by PR topography.

I am no meteorolog, but this is nonsense. The thunderstorms start way too far soutwest from PR for that to be true.

Have a look at the long range radar from San Juan. It almost looks like there is a countervortex (clockwise) rotating just north of St. Thomas.

Yeah I guess, originally it looked like it had something to due with Puerto Rico, and maybe to a minor degree it does, but there is still some intense convection firing south of PR. Hopefully somebody can help out here.

its a very wet feederband. Typically, these cna extend well to the east of the center

Seems to be very wierd storm movement on the radar, some must be developing in a steering layer that is helping them move in a WNW or NW movement, others seem to be moving in a ENE or NE direction.
