STORMTRACKER33 — - A weather pattern has developed over the central part of the United States that will produce several episodes of heavy rains across the Middle Mississippi River Valley and the Ohio River Valley. Excessive rainfall runoff will bring much of the central and lower Mississippi River and the Atchafalaya River into very high levels over the next several weeks. This situation will have to be monitored very closely and re-evaluated with each new round of rain over the next few days.
