The Rochester City Lines bus company posted the announcement below this morning: 

After reviewing weather and road conditions in our area that have developed and intensified overnight, RCL has made the decision NOT TO OFFER COMMUTER SERVICE on Friday the 24th. We encourage all travelers to stay safe, and stay home. Please help us spread the word!

Several schools and organizations have already cancelled classes and activities today.

Meanwhile, MnDOT is advising no travel for anyone in Southeast Minnesota. MnDOT's road map looked like this at 4:30 a.m.

Purple roads = travel NOT advised.  Exclamation points indicate accidents, crashes and spin outs.
