CNN Worldwide is once again combining the on-air programming for CNN/U.S. and CNNI throughout the day today. Executives believe simulcasting Saturday’s coverage, which will be dominated by the situation in Japan, is more resourceful than both networks going it alone.

At 6amET, CNNI’s Andrew Stevens in Hong Kong and CNN/U.S.’s Randi Kaye in New York co-anchored coverage. At 9amET CNNI’s Becky Anderson took over from London as Kaye continued in New York. That will continue until 11amET, when Fredricka Whitfield it CNN Atlanta joins Anderson. At Noon, John Vause takes over for Anderson. Vause, an Australian who has worked for CNN in Asia, will anchor from Atlanta with Whitfield. Following all this?

The simulcast continues into the afternoon and evening hours.
