Folks along the Minnesota River in the southwest metro should remain alert for rising waters this week. Here is the latest list of flood related road closures from MNDOT.

Good News for St. Paul?

The swollen Minnesota River pours into the Mississippi before it reaches St. Paul. Thankfully the heaviest rains last week were confined to southern Minnesota and the Minnesota River watershed. That means the mighty Miss will be able to absorb much of the floodwater without producing record levels on the relatively well protected Mississippi in St. Paul. Still, “major” flood stage will be reached and Harriet Island may submerge this week.
