Talking Points<br />
• The Mississippi River is cresting near Greenville, MS.<br />
• It will likely be early next week before we get cresting<br />
conditions at New Orleans and Morgan City.<br />
• The Mississippi & Atchafalaya Rivers are forecast to crest at<br />
levels which are similar to May 2009 and several feet lower<br />
than January 2016.<br />
• Rainfall over the next two days doesn’t appear to<br />
significantly impact the Mississippi & Atchafalaya Rivers<br />
forecast.
