He still has a ways to go, and things can change as we well know. But now is the time to check and recheck your preps, check on your evacuation routes, establish your possible bug out locations, and basically make sure everything is in order. Fill your gas tanks, water containers, and check your tires, belts, hoses, etc. on your car.
Ike has some nice warm water to cover before his arrival, so he'll spin right back up after he clears Cuba. I suspect the catagory 3 forcast shown in the above map is a bit optimistic. Catagory 4 is my bet. Dolly cooled the Gulf a bit, but it's still pretty warm, about the same temperature as where Ike was a catagory 4 just a few days ago. Couple that with little to no wind shear and you've got perfect conditions for a lot of strengthening. Keep an eye on this bugger, and be aware, be informed, be prepared!
