Flooding in southern Minnesota has intensified and expanded as a result of 3-8 inches of rain the last 24 hours and up to 14 inches in the last 7 days. 1-3 inches is forecast tonight, with locally heavier amounts possible. Flooding now spans tributaries to the Minnesota, Missouri and Iowa Rivers, and Mississippi River tributaries downstream, within, and immediately upstream of the Twin Cities. The Red River Basin tributaries are rising. In northern Minnesota the flood recession continues in the Rainy River basin along the Canadian Border.
To date 4 streamgages with 28-85 years of record have provisional peaks of record. Four streamgages have annual exceedance probabilities of less than 1 percent. Ratings have been extended at 2 streamgages based on measurements, and two more will likely be extended tomorrow.
