While this isn't exactly something to jump for joy over, it's ended the tropical storm/hurricane debate when Isaac is discussed. As of approximately 1130 CDT it's officially been determined to be a hurricane. Because of this, I stepped out to see how much the sky had changed since this morning, since I had some laundry to do, I got some shots around 1000 as well, but waited to post them until later. With the growing number of images, you can see the progression from clear skies, to the darker clouds, but at that point, thats all. No rain yet, no high winds, and so forth. Just some more clouds.
Next update: ~1600 CDT 28 August 2012, unless major change occur again.
