As of 11 pm Issac was about 75 miles west of Key West near the Dry Tortugas National Park.
Maximum winds from the Hurricane Hunter aircraft was 55 knots and Issac was heading west-northwest near 14 mph. Issac should slow its forward sped a bit and gain some strength as it bears down on the Gulf Coast of Louisiana / Mississippi. The maximum in the intensity forecast is for a moderate to high category one hurricane before landfall. my experience with the Lower Mississippi River Forecast Center, National Weather Service WFO Slidell, and the Corps of Engineers, is that they are the best in the business. While working in Ft. Worth during the floods of 2011 I believe the City of New Orleans, and the State of Louisiana will keep their communities safe with Issac.

Keep checking your local National Weather Service Office website for hurricane local statements that will have information on closings, shelters, and evacuations in your area.
