A Flood Advisory has been issued for the Mississippi River at Memphis due to recent heavy rain upstream (north) from Memphis, as well as winter snow melting upstream and flowing into the Mississippi or it's feeder rivers. This morning's river stage at Memphis was 25.4 feet (above an arbitrary level chosen as "zero"). The river is forecast to rise above the "action stage" of 28.0 feet Friday afternoon, then reach 32.0 feet by a week from tomorrow. Flood stage is 34.0 feet and it's not out of the question that the river could go above flood stage sometime later in March.
At 28.0 feet, flooding is occurring in isolated lowlands along the river, and at 32.0 feet flooding in occurring over unprotected farmland along the river, mainly on the Arkansas side.You will also notice that tributaries like the Wolf and Loosahatchie Rivers may begin to overflow their banks into susceptible lowlands.

Notice in particular the 200-300% of normal rainfall seen over the Ohio Valley! It's no wonder the river is rising!
