This morning. Record breaking floods are threatening to burst the Rapidan Dam in the upper Midwest. Officials warning families near Mankato Minnesota along the Blue Earth River to be ready to evacuate. Storms dumped nearly 18 inches of rain engulfing neighborhoods leaving structures barely hanging on a very long night. Now the threat of our house, my family house where I grew up is threatened by the force of Mother Nature, the water and you're not stopping Mother Nature, rain and debris like trees falling and metal from a destroyed energy substation are straining conditions. Officials are now warning the dam is an imminent failure condition. This video shows the remnants after flooding caused a rail bridge connecting Iowa and South Dakota to partially collapse railway bridge ripped apart by that raging river. You see the gushing water. Officials say it crested at 45 ft. That's historic levels forcing many that live nearby to evacuate. Barriers were built to withstand just 46 ft overnight.
