The National Oceanic and Atmospheric Administration’s (NOAA) Lower Mississippi River Forecast Center (LMRFC) released the update below (today) to document the low river stage conditions. The LMRFC provided the following text along with this update that details low water stage predictions from Cairo (IL) to Baton Rouge (LA). 


No rainfall and no changes from Monday’s update.


The lower Ohio River continues to have stage fluctuations due to lock/dam operations.  Cairo, IL was at 7.3ft this morning and it is expected to rise a few more tenths by tomorrow morning. 


The 7 day forecast doesn’t show much rainfall over the basin.  Some of the long range models are hinting at better chances of rainfall over the lower Missouri and middle Mississippi Valleys by next weekend.  Right now, the long range river models are not picking up on any additional runoff from this potential rainfall event.


The 16 day future rainfall model continues to show falls on the lower Ohio and lower Mississippi Rivers through the rest of September into mid October.  The forecast for Cairo, IL still shows river levels approaching the 5.0ft level by the end of the month.  The forecast levels for the end of the month would be similar to 2022 levels. (Emphasis supplied)
