Good morning,
Overnight, "Hanna" spun over Hispaniola and the Bahamas causing destruction on those islands. If you look closely at the high res satellite image courtesy of NASA you can see how those two land-masses have sheared the storm apart, if only just a bit. But enough that Hanna is now a tropical storm.

Where will Hanna go? She seems destined for the southeast coast of the U-S, but where?

The latest GFS computer model, one that handled the track of Gustav very well, places "Hanna" near Myrtle Beach on Saturday. It will be close enough to the coast that if you have travel plans later this week or this weekend any where from the Space Coast of Florida up to the beaches of North Carolina you will be impacted in one shape or form from this storm. It could be rough surf or heavy rain or gusty winds.
Have a great Wednesday,
Brett
