NEW ORLEANS — Huge and slow, Tropical Storm Isaac lumbered up through the Gulf of Mexico from Florida toward Louisiana and Mississippi on Monday, growing stronger by the hour and putting coastal residents on notice of an extremely wet and potentially destructive next few days.

The tracking forecasts reached a consensus by Monday night that the storm, which was a little over 200 miles southeast of the mouth of the Mississippi River and on the verge of becoming a hurricane, would land overnight Tuesday somewhere around southeastern Louisiana as a Category 2 hurricane.

But Isaac has been fickle and confounded predictions all along, and its intensification is just beginning.
