The chance of flooding is clearly up. There's now about a 98% chance of the river cresting in St. Paul at or around 20 feet. That would be in the purple "major flooding" zone. What is particularly interesting about this year's predictions is that all probabilities are in the purple zone. In other words, St. Paul is headed into the major flood stage one way or the other.
There's a graph for that too.
Here's how to read the graph. Everything in gray is pretty much a certainty (greater than 90% probability) Blue is 50 to 90% probability so still very good. Red is the outside probabilities of 10-50%.
