Debris provides evidence of the effects and impact of a hurricane or a tornado. Remnants of homes, buildings and other objects help experts in categorizing the strength of a storm. Preliminary analysis of the Moore, Okla., tornado, originally identified it as 2½ miles in width, on the ground for 27 minutes, devastating an area comparable to a square-mile path from Baton Rouge to New Orleans. Moore has incurred the wrath of tornadoes on three occasions since 1998, so many question why storm rooms aren’t in place. Homes in Oklahoma are on post-tension slabs similar to ours due to clay and soil. These homes cannot withstand winds in excess of 90 mph, and FEMA standards for in-home safety rooms are constantly changing. Future homes and schools may include mandatory storm safety rooms.
