NEW YORK (AP) -- Television networks are preparing to juggle two major stories in the coming days as Tropical Storm Isaac heads toward New Orleans after side-swiping the site of the GOP national convention in Tampa.

Anderson Cooper of CNN and Shepard Smith of Fox News Channel were shifted Monday by their networks to New Orleans. It's an odd rerun: four years ago Cooper also left a Republican convention to head to the gulf region ahead of Hurricane Gustav.

News networks already had to make programming changes with the Republicans postponing the opening night of their convention on Monday. The strength and timing of the storm will also affect how much time will be spent on each story.

Said one network executive: "Expect to see a lot of split-screens."
