Until now the start of hurricane season back on June 1st has been quiet. With soon to be hurricane Isaac, that’s about to change. Exactly where he will come ashore in the US is still unknown, though better projections will probably be in place by Saturday of the coming weekend. As of Thursday evening Isaac was still a tropical storm, but after clearing Cuba in the near future, it will probably rise to hurricane strength.
As with any tropical system, many changes will take place before a better track estimated landfall are known.
