Officials have ordered 11,000 Minot, North Dakota, residents to flee their homes by 6pm today, in what will be their second evacuation this month. The Souris River is expected to spill over the city's protective levees soon, in its worst flood in four decades, the AP reports. Officials say that even the 6pm deadline might be cutting it close; they'll sound a warning siren if the water crests the levees sooner.
Minot residents have already been forced to evacuate once earlier this month, when the river rose to 1,554.1 feet. They were allowed back to their homes, but told to be ready to leave quickly if need be. Now, the water is even higher at 1,554.4 feet, putting it just a tenth of an inch short of the the historic flood of 1969. By this weekend, it's expected to hit 1,563 feet, in which case it would pass the all-time high recorded in 1881 by a whopping five feet. (Read more Minot, North Dakota stories.)
