January 13: Report: Bad Data Failed To Predict Nashville Flood

Posted Thursday, January 13, 2011 --- 7:45 a.m.

NASHVILLE, Tenn. (AP) -- The National Weather Service has found that its river forecasters used inaccurate data in making predictions about the approaching flood waters that devastated Nashville in May.

An internal report released Wednesday by the National Weather Service found that the flawed predictions mean that the service failed to warn of major flooding until after it happened.

The flooding on May 1 and 2 killed 22 people around the state and caused more than $2 billion in damage in Nashville alone.

The weather service report found that its prediction relied on data from the U.S. Army Corps of Engineers estimating how much water it was releasing from dams, even after the data was known to be inaccurate.
