CHARLOTTE, N.C. – Democratic officials are moving President Barack Obama's convention speech Thursday indoors because of the possibility of severe weather.

Obama had planned to accept his party's nomination in an outdoor football stadium before a crowd of up to 74,000 people. But Obama officials said forecasters have predicted severe thunderstorms Thursday in the 9 p.m. to 10 p.m. hour, raising concerns about the safety of supporters, volunteers, staff members and law enforcement.

Officials said Thursday's entire program would be moved indoors, including Vice President Joe Biden's speech. The events will be held at the Time Warner Cable Arena, the site of the first two days of the convention proceedings.
