Due to the current long wave/ cold front moving though the SE US it is entirely possible. Actually it is probably the main reason that Tomas didn't make it into the GOM or the FL Straits.

It has to do with the zones in the warning below. Offshore waters are beyond 20nm offshore so anything beyond the 20nm limit would be highlighted as the watch or warning area. The highlighted area is a false highlight due to software design, as ED pointed out, or the way the coastal and offshore marine zones are set up. Again software/ human interface.
