Update: Storms soak southern MN, tornado spotted near Mankato

A watch is serious, but slightly less severe than a warning. A warning means danger is imminent.

Another line of severe storms passed through southern Minnesota Wednesday, bringing a tornado to the skies near Mankato and a report of another twister in Wabasha County.

The tornado was part of an afternoon round of storms, but a second line of severe weather passed through in the evening. By sundown the biggest threat was for flooding in the northern Twin Cities area, although some counties were still under a tornado watch.

A tornado warning means danger is very likely imminent. If there's one in your area, get to shelter immediately.

8:40 – Storms gone, but flooding potential remains

All of Minnesota's thunderstorm warnings have expired or been cancelled.

Flash flooding remains a threat, though, especially in the northern part of the Twin Cities area. The National Weather Service says during some of this evening's downpours rain fell at the rate of one inch in 30 minutes.

A tornado watch remained in effect for seven counties from the southern Twin Cities south and east to Winona.

8:10 – Severe storms moving into Wisconsin

Severe thunderstorm warnings are out for Wabasha and Goodhue Counties, until 8:30 and 8:45, respectively.

The Weather Service says winds with these storms can reach 60 mph. Pepin and Pierce Counties in western Wisconsin are also included in the Goodhue County warning.

7:20 p.m. – Flash flood warning for Twin Cities

As a new round of rain begins falling in the Twin Cities, flood worries are growing.

A flash flood warning includes Anoka, Hennepin, and Ramsey Counties. The new rain is on top of up to two inches that fell earlier in the day. The warning lasts until 10:15 p.m.

This Weather Service tweet shows special concern about a few suburbs in Anoka County.

7 p.m. – A new storm warning

The Weather Service has issued severe thunderstorm warnings for Fillmore and Mower Counties until 7:30.

Forecasters say winds up to 70 miles per hour may take down trees in Fillmore County and quarter-sized hail may damage cars in Mower County.

Meanwhile a tornado watch continues for much of southern Minnesota and a flash flood warning is in effect for the Mankato area.

Also, video of a funnel cloud spotted this afternoon in Plainview, which is in Wabasha County, has hit social media.

5:15 p.m. – Flash flood warning

With all the rain the Mankato area has been getting recently, a flash flood warning has been issued.

In some areas, the National Weather Service says up to 2 inches of rain have fallen in an hour today.

People are reminded to watch out for flooded roads, and don't drive into them.

The warning is in effect until 7 p.m.

4:31 p.m. – Tornado warning expires

The rotation in the storm system near Mankato has weakened, the National Weather Service Twin Cities tweeted. So the tornado warning has been allowed to expire.

As of 4:31 p.m., there are no tornado warnings in Minnesota – however, that tornado watch still exists. The yellow on the map below is the area the watch covers:

That watch is in effect until about 10 p.m. for most places.

A watch means dangerous weather could happen, so pay attention to the forecast. Things could be elevated to a more serious warning very quickly.

4:18 p.m. – Tornado spotted near Mankato

The weather service minutes later said the tornado was moving north at 40 mph, and is telling anyone nearby to find shelter asap.

The La Crosse National Weather Service said dime-size hail was spotted in Altura, Minnesota. That's a little west of Winona.

4:05 p.m. – Warnings, watches

The tornado watch is in effect until 10 p.m. Wednesday. The National Weather Service says it includes 16 counties: Sibley, Dakota, Scott, Blue Earth, Brown, Faribault, Freeborn, Le Sueur, Martin, Nicollet, Rice, Steele, Waseca, Watonwan, Goodhue and Redwood.

A more severe tornado warning popped up for a few areas Wednesday afternoon. It's in effect for northeastern Steele County, north-central Blue Earth County, and southeast Nicollet County until 4:30 p.m.

The warning says the radar indicated rotation with the storm, and said flying debris will be dangerous. Damage to cars, homes and roofs is likely, as is tree damage.

There are also some severe thunderstorm warnings until 4:30 p.m. for southeastern Brown County, northwestern Blue Earth County, and central Nicollet County.

There are 60 mpg wind gusts possible, with half-dollar size hail.

This latest round of severe weather comes a day after strong storms swept through western Wisconsin. One person was killed and dozens were injured when a tornado hit Prairie Lake Estate Mobile Home Park.
