This is a forecast of the wind gust field for Isaac valid at 1pm Tuesday. Forecast gusts to 75 knots (86 mph) will have made it to the mouth of the Mississippi River at this time and 60-65 mph gusts are just reaching the State of Mississippi barrier islands.

The storm is forecast to move almost straight northwest from this point which is dangerous for New Orleans, especially if any strengthening occurs. Keeping in mind the counter clockwise direction of wind rotation, there will be an extended period of north winds across Lake Ponchartrain. Assuming the new levees hold, things are fine. But, they have never been tested.
