Monitor this web site, www.nhc.noaa.gov/ , if you plan to visit tropical highpoints, such as Loggerhead Key in Dry Tortugas National Park. It provides the current status of tropical storms in the Carribean, Atlantic, eastern Pacific, and Gulf.

Even though a storm may not directly hit a point, it can stir up the waters more than a thousand miles away.

For Dry Tortugas National Park in the Florida Keys, late August early September is the peak time for these storms, although the official season is June to November. This also coincides with the calmest waters, so the trick is to get ready, watch the forecast, and go there in-between storms (or better yet, go there for an extended time and wait them out).
