The cable networks are planning special coverage Sunday morning for the dedication of the Martin Luther King, Jr. National Memorial in Washington, D.C. But Hurricane Irene could scrap some of the outdoor anchor positions the nets had been planning. And while the event will go on rain or shine, the ceremony may be pushed back. Dr. King’s Memorial is on a four-acre plot on the northwest corner of the Tidal Basin.

The dedication comes on the 48th anniversary of King’s “I Have a Dream” speech from the nearby Lincoln Memorial. Here’s what the nets are planning, weather permitting:

  • CNN’s Candy Crowley, T.J. Holmes and Soledad O’Brien will anchor live coverage from 11amET-1pmET with reports beginning as early as 6amET and a special edition of “State of the Union” at 9amET. Other specials include a Holmes-hosted half hour at 7:30pm Saturday and the O’Brien documentary “MLK: Words that Changed a Nation” Sunday at 8pmET/PT.
