Tropical Storm Expected to Miss Oil Spill (for Now)

Cross your fingers: The first tropical storm of the season has formed in the Caribbean. Alex is expected to pass over the Yucatan Peninsula this weekend, and while current forecast models say it won't pass over the oil spill in the Gulf of Mexico, its path could change once it starts picking up speed. And then, of course, the next storm could be worse.

"The greatest nightmare with this storm approaching is that it takes this oil on the surface of the Gulf and blows it over the barrier islands into the bays and the estuaries," Florida Senator Bill Nelson tells CNN. "And that is where you really get the enormous destruction, because it's just very difficult to clean up those pristine bays." (More Gulf oil spill stories.)
