Flooding in at least 8 states along portions of the Mississippi River – due to relentless, record-breaking spring rainfall – is the longest-lasting since the “Great Flood” of 1927, the National Weather Service said. The 1927 flood, which Weatherwise magazine called “perhaps the most underrated weather disaster of the century,” remains the benchmark flood event for the nation’s biggest river. Anytime a modern flood can be mentioned in the same breath as the Great Flood is newsworthy: During that historic flood, hundreds of thousands of people fled their homes as millions of acres of land and towns went underwater. At one point in 1927, along the Tennessee border, the Mississippi rose an astonishing 56.5 feet above flood stage, and in Arkansas, the river ballooned to 80 miles wide, according to the book Extreme Weather by Christopher Burt.
