MINNEAPOLIS (AP) - A line of storms crossing southern Minnesota has dumped several inches of rain and kicked up strong winds.

The National Weather Service reports three tornadoes touched down in south-central Minnesota on Tuesday but no major damage was reported.

In Blue Earth County, authorities reported a tree toppled onto a house. Trees and branches also were knocked down in Watonwan County. A wind gust of 51 mph was reported about 10 miles south of Owatonna in Steele County.

An estimated 2-3 inches of rain drenched several cities in southern Minnesota, including Mankato, Lake Crystal, Madelia and Waseca.

Parts of south-central and southeastern Minnesota are under a flash flood watch until 1 a.m. Wednesday.
