The tornado that ripped through Moore, Oklahoma yesterday has claimed at least 91 lives and caused hundreds of injuries. As the death toll mounts, the twister will go down in history as one of the deadliest in U.S. history.

• Editor’s note, 5/21/13, 9:23 a.m. MDT: Amy Ellis with the Oklahoma Medical Examiner has said that previous counts released by their office for lives lost as reported in this story were incorrect. The Medical Examiner said their office now puts the death toll at 24, 9 of which were children.

Forecasters had warned that Monday would bring dangerous severe weather, the third of a series of days in the past week that had been deadly. Warnings went out as the tornado formed near Newcastle and began its deadly trek to the northeast.

The minutes were crucial to saving lives but as the storm grew in ferocity, even the most robust shelters were proven incapable of withstanding the onslaught.
