This from the AQUA earth-monitoring satellite. These tornadoes were so large they left visible brown gashes on the Alabama countryside. To help you find the gashes, storm chaser Aaron Kennedy put yellow lines parallel to the tornado's tracks. I have added the arrows. The city of Tuscaloosa is between the "a" and my first arrow. The path across Birmingham was largely covered by clouds when the satellite passed over.
ADDITION: Excellent photo coverage from The Boston Globe.
