The following post is NOT an official forecast and should not be used as such. It is just the opinion of the poster and may or may not be backed by sound meteorological data. It is NOT endorsed by any professional institution including storm2k.org For Official Information please refer to the NHC and NWS products.
I think the farthest north it could go is Palm Beach County. A direct hit is more likely farther south in Miami-Dade. The NHC is forecasting a TS when reaching S. Florida but I think they are being conservative. Storms in this part of the Atlantic have historically developed faster than anywhere else (e.g. Camille, Katrina, etc). A near major hurricane impacting S. Florida would not be out of the question here.
