MINNEAPOLIS (AP) - A winter storm warning is now out for parts of south-central Minnesota as fresh snow creates difficult driving conditions on one of the busiest travel days of the year.

The National Weather Service says the heaviest snow is expected south of the Twin Cities metro area, near Mankato, St. Peter, Faribault, Waseca and Owatonna. It predicts snow totals of 7 to 10 inches by late Wednesday afternoon in those areas. Eight inches of snow had fallen by 8 a.m. at Winnebago, while six inches were reported in St. Peter, Amboy and Milroy.

The Minnesota Department of Transportation says southbound Interstate 35 north of Faribault had to be closed due to an injury accident.

The snowy weather is delaying some arrivals at Minneapolis-St. Paul International Airport.

The Thanksgiving weekend is traditionally one of the most dangerous holiday weekends on Minnesota roads.

State records show distracted driving was the most common factor in 564 crashes involving 1,436 cars between Nov. 27 and Dec. 1 last year. That's ahead of failure to yield to other motorists, speeding, and drunken or drugged driving.
