      Tropical Storm Isaac forms; Fla. may be in track

      Tropical Storm Isaac formed in the Atlantic Tuesday afternoon and has a track that could possibly take it toward Florida where the Republican National Convention will be held next week.

      Storm warnings have been issued for the Lesser Antilles in the Caribbean including Martinique, Guadeloupe and St. Martin.

      It is too soon to say what exact path the storm will take. There is some consistency that takes Isaac across the Lesser Antilles into northern parts of the Caribbean Sea. From there, models are a bit more uncertain, but have this storm moving into Cuba by the weekend as a category 1 hurricane. At that point, it will depend on how much Isaac weakens over land as to where it will head early next week.
