Comments are mine …
Data and forecasts provided by the NWS/Lower Mississippi River Forecast Center (LMRFC), the USGS and the Army Corps of Engineers. The LMRFC, the USGS, and the Corps are the river stage and flow experts.
Mississippi River forecasts focus on the LMRFC’s ‘experimental’ 28-day projections, including 16 days for forecasted rainfall. Comments for other Louisiana gaging sites are based on LMRFC “7-day” forecasts and generally include only 24 hours for forecasted rainfall.
