Tropical Storm "Isaac", the ninth named storm of the Atlantic-Caribbean hurricane season, has formed in the Atlantic Ocean and looked to be on its way to strengthening into a hurricane, although models indicate the storm's path will keep it out of the Gulf of Mexico.......................Forecasters in Houston said Isaac was unlikely to make its way into the Gulf of Mexico and was not at this time expected to affect oil and gas operations there.

I would not worry about it, Isaac tends to blow hot and cold.
