Being close to the great Mississippi, which will drain a wide area experiencing torrential rainstorms, would put any bordering land, at risk or flood surges, no matter how high the hill. Large amounts of water may pass though, at great speed, and when encountering an obstruction such as a hill, rise up as the path of least resistance. These flood surges will not be gentle, so escape in a boat, which would capsize and tumble in the roistrous waves, is not likely.
