A possibility occurred to me. The fires I have been spoeaking of was shown on NBC's local affiliate.
It may have been canned video, from a day or two ago.
Fingers crossed, because it was a BIG fire.
NBC live reporting that the Mississippi River is not, repeat, not, blocked.
Traffic is limited and tightly controlled for reasons unknown, but the channel is open, per NBC. They mention submerged hazards still existing, so I'm guessing they have only completed a preliminary assessment.
