Igor

Igor is a tropical storm out by the Cape Verde Islands off western Africa.  There's a reason many hurricanes are called Cape Verde hurricanes - it's a spawning ground.  I think you'll start hearing a lot about Igor since it's moving westward and there's lots of warm water (fuel for hurricane development) and light wind shear (wind shear kills hurricanes) in its path.  It has the potential for developing into a large and powerful hurricane when (if) it reaches North America in a week or so.  Expect it to reach category 1 hurricane wind speeds (74-95 mph) by Friday or Saturday and strengthen as it plows westward across the bathtub-warm Atlantic.
