Hey guys i found this article on the web....check it out! A farm broadcaster from North Carolina Interviewed Nebraska State Climatologist Al Dutcher about the current weather situation.Dutcher says since the system is already so well established this early in the year, theres's a possibility it could actually expand westward this summer.this situation raises the potential for a couple of scenerios...
He says if we do have this high pressure system off the southeast coast it will cause the flow to move more out of the due south,” explains Dutcher.
here's the link....

Think of a map of the US and western Atlantic. Picture an H near Bermuda repesenting the High pressure area center. Then think of a clockwise flow around this H. When storms move into an area below this H (Cape Verde storms typically do) the clockwise flow will "push" them westward towards the SE coast. Thus, the chances of hurricanes making landfall in the SE US increases.
It all depends on exactly where the High is and how strong because while these storms can approach the coast, they can recurve on the extreme western periphery of the High and miss the U.S. This latter scenario is more typical. An alternative common scenario is that the high weakens allowing these storms to curve out to sea much sooner out in the far Atlantic.
Please note though that my opinion about the Bermuda High is just that - a subjective statement. It is too early to pinpoint where this High will be or how strong it will get. The H is transient - it weakens, strenghtens, and moves erratically over time but generally is positioned near Bermuda in the summer months. It retreats east towards the Azores in the Eastern Atlantic during the winter months.

Good points about the Bermuda High Boca Chris. Its also important to remember that since it is usually shifting around, it is all about timing.
A stronger more persistent high obviously can raise the chances for a storm to come a little closer to the southeast coast during a given season, but if a short wave happens to come by at the right time, the storm can still be deflected northward or even out to sea because it can create a weakness in the high. If I recall, Isabel turned northwest then north a little earlier than expected back in 2003 due to the presence of Henri, creating just enough of a weakness in the ridge that was in place. If anyone has other information about this, feel free to correct me. I also think that there was some thought, initially, that Gaston was going to do the same thing to Frances in 04 as she was approaching from the east. Again, timing has alot to do with it I think.
