Irene is still soo weak that its center is being influenced by its midlevel low on its NW side. The center has slowed to a crawl while the midlevel low is moving by on its N or now NW side near 23N and 58W. Quicksat pass shows Irene has multiple centers and probably the main circulation near 22.6N and 57.5W. just NE of the 11am NHC position.
The center might get better defined tonight into tomorrow as the system gets better established with a ridge to its NW. I expect a w or wnw movement thru the period. Any drop in pressure or strengthning over the next day or so would push this NW or even NNW towards Bermuda area but if she stays weak by 65W then a more W movement to near 25-27N and 75W by Saturday. It should strengthn into a hurricane by the weekend. By then its too early to tell how strong the ridge will be to let us know if she will continue then wnw towards Florida or move NW and N towards the Carolinas.
For now again like the last many days....its a watch and see.......... SVB
