As of 9PM Saturday evening, Tropical Storm Isaac moves northwestward just off the coast of Northeastern Cuba.
This large storm is moving at 20 mph with sustained winds at 60 mph. For it to become a hurricane, it must have sustained winds of 74 mph.
The models are wanting to take the storm into the Gulf of Mexico. The very warm water temperatures will aide in strengthening the storm into a Category 1 hurricane by Monday. It is expected to make landfall on the Southern Gulf Coast by Wednesday evening. Since Wednesday is still a few days away, the storm could make landfall as far west as the Mississippi/Louisiana border to as far east as the Florida Panhandle/Georgia border. Where it goes after that depends on a cold front approaching us from the west which will send the remnants of the storm across the Appalachians into our neck of the woods, or another ridge of high pressure keeps it more west of us. Some models are trending that it will climb up the Mississippi River Valley and we will get rain from the cold front. The timing of that will be Wednesday-Thursday. It will be interesting to watch what the Appalachians do to the storm if it decides to head our way. We will continue to track Isaac.
