MOORE, Okla. - The tornado that tore through an Oklahoma City suburb destroyed or damaged as many as 13,000 homes and may have caused $2 billion in overall damage, officials said Wednesday.

Oklahoma Insurance Department spokeswoman Calley Herth told The Associated Press that the early monetary damage tally is based on visual assessments of the extensive disaster zone that stretches more than 17 miles and the fact that Monday's tornado was on the ground for 40 minutes.

For the first time Wednesday, authorities provided a clearer accounting of the destruction.
