The National Oceanic and Atmospheric Administration’s (NOAA) Lower Mississippi River Forecast Center (LMRFC) released this update (today) to document the low river stage conditions. The LMRFC provided the following text along with the attachment for this update that details low water stage predictions from Cairo (IL) to Baton Rouge (LA).
“Again, no big changes but some hints of heavy rain potentially for late next week.
Very minor rises (1 foot) from the middle Mississippi River are showing up on portions of the lower Mississippi River. The peak of the rises are south of Memphis, TN and should approach the confluence with the Arkansas River over the weekend. The rises will likely dampen as they approach the lower portions of the river during the next week.
The lower Ohio River at Cairo, IL was at 6.4 ft this morning as it continues to fluctuate with lock/dam and power operations. The forecast shows Cairo, IL oscillating between 5.0 ft to 7.0 ft over the next several days.
The 7 day rainfall forecast is showing some encouraging signs. The forecast shows 1 to 3 inches of rainfall over the lower Missouri, middle Mississippi, and western portions of the Ohio Valley. The rainfall is projected for late next week and it is too soon to know how much runoff will be generated from this event. Hopefully this trend will continue in the coming days.
The 16 day rainfall forecast shows little improvement to the low water conditions. Cairo, IL is still forecast to reach the 5.0ft range by the end of October.” (Emphasis supplied)
