Focus is still on the EPac as of right now. There is a weak center of circulation over the Yucatan Peninsula right now, though that impressive convective flare-up to its west is only marginally associated with that feature. Instead, it is associated with upper-level diffluence as the upper-level trough over the SE US slides a bit further southward. WV imagery indicates a developing upper-level low along that trough in the vicinity of the convection; that's certainly not favorable for any sort of tropical development. Another surge of dry air is sliding through the central Gulf of Mexico now and is encroaching upon the Bay of Campeche. Simply put, I don't think anything tropical can get going in that sort of environment. Things can change, however, and we'll watch it.
The feature in the EPac isn't as impressive in terms of a convective flare-up right now, but it does have a center of circulation -- see http://manati.orbit.nesdis.noaa.gov/dataimages21/cur_hires/zooms/WMBas64.png -- and the flow through the pass in the Isthmus of Tehuantepec is only adding to the circulation along the west side of the feature. What convection is there is much more organized than in the Atlantic and the shear is not nearly as large of a factor. My thinking as of now is that something there develops but doesn't move a whole lot over the next few days, while nothing significant gets going in the Atlantic basin for now. Might get an inverted trough or a very weak area of low pressure sliding into the Bay of Campeche/western Gulf, but bona fide tropical development? Ehhh...
