The Mississippi area was dealing with the effects of Hurricane Isaac.
Mrs. Roberts made numerous appearances on Good Morning America.
She was a Gulf Coast icon for more than four decades, working with organizations and state and local agencies, and she became known for her ability to get things done.
She was the first black person to serve as chairman of the Mississippi State Board of Education in the 1980s.
Mrs. Roberts also had a passion for poetry and music. She collaborated with her daughter on a book titled My Story, My Song - Mother-Daughter Reflections on Life and Faith.
"I sing because the music of the church speaks my soul language," she wrote.
The family was gathered in Pass Christian, Miss., and planned a small private service, Cibrowski said.
The death came on the same day Roberts said goodbye to her coworkers and audience before starting her medical leave. Sally-Ann Roberts, a morning anchor at WWL-TV in New Orleans, is donating the marrow to her sister.
Mrs. Roberts' husband, Col. Lawrence E. Roberts, who was a member of the all-black U.S. Army Air Corps, also called the Tuskegee Airmen, died in 2004. In addition to her two daughters, she is survived by another daughter, a son, and eight grandchildren. - AP
