In the past, I have noticed that very strong tropical systems can defy all rules and redefine or create their own patterns. For instance, the blocking ridge to the north of Dean.
If Dean became a strong hurricane, could it start to control the weather around it as to in effectively overcome the ridge and simply punch into it? I seem to recall past systems where they became so strong that they over took the very systems that were steering or controling them. In effect creating their own weather patterns around them.

Most of the time it is the weaker systems that defy the trofs/ ridges as they come across. The powerful hurricanes, while they do create their own environments, the tremendous heat release by the storm tends to pump the ridge............,aking the ridge even stronger.........which then usually leads to a sharper trof, and out she goes. Again, the reason hurricanes are born are to redistribute heat from the tropics to the northern latitudes via the westerlies. So nature is going to do it's darnest to turn that big sucker northward. _________________ No...I am not a tropical forecaster....But I did stay at a Holiday Inn Express once

Yes, tropical cyclones can penetrate into areas of high pressure, but the extent to which this occurs depends more on the depth of the high than the strength of the cyclone. Fortunately for us, the high off the eastern seaboard is going to be very substantial in two days.
