Rare fall floods set records

The term "spring flood" is getting a rival this September.

For the first time on record, some southern Minnesota rivers will set top 5 floods of record during fall this week. Last week's torrential rains capped off a wet September with rainfall totals anywhere from 5.5" (metro) to over 12" (south central Minnesota).

Four of the current top 5 record floods on the Minnesota River occurred in spring. The other occurred in June. This will be the first time a top 5 flood has occurred in September. You can track current and forecast river levels here.

The Cottonwood River at New Ulm came within a foot of the all time flood of record last weekend.

Check out some of the expected flood crests on the Minnesota River this week.

Mild dry weather will help:

The forecast is favorable for flood ravaged communities and rain soaked farm fields over the next two weeks. Minnesota will be on the east side of a ridge of high pressure, which means generally mild and dry weather for the next 10 days to two weeks.

After a wet September, it looks like we'll close the month on a dry note and open October on the mild side.
