The large-scale models have seemingly responded to the G-IV jet mission by showing a slightly weaker ridge north of Dean...with a motion that is slower and a little to the right of previous forecasts.

Not good.

The development of Dean has apparently been slowed by a combination of dry air intrusion in the western semicircle and light westerly shear. These conditions may persist for another 12-24 hr...so the intensity forecast calls for slow strengthening during this time.

Dean is already looking like the dry air's impact is lessening.

I’m in Puerto Rico right now... returning to Baltimore tonight... Dean will be a big rainmaker in PR tomorrow and Sunday, but the biggest concern of the people here is that Dean takes a northwardly last-minute turn and strikes the island head-on, just like Hugo in ‘89 and Georges in ‘98...
