A historic courthouse, theatre and a large factory fell in the path of a storm system’s damage as it generated several tornadoes across central Iowa on Thursday.
Several funnel clouds developed Thursday from the thunderstorm as it moved north of Des Moines near Bondurant.
Additional funnels were reported as the storm moved east of Des Moines past Altoona, Prairie City and Colfax.
Warnings were issued as the storms moved east.
Several buildings were reported damaged by a tornado in the main business district in Marshalltown, including the historic courthouse.
Initial reports to the National Weather Service indicated the historic Marshall County Courthouse’s tower was damaged in a Thursday afternoon tornado, and a weather service spotter reported vehicles overturned and numerous trees down.
A woman working at Hammer Medical Supply in the city’s downtown said her building has minor damage.
She said other nearby buildings including The Orpheum, a theatre built in 1948, also are damaged. Another nearby brick building is missing one side, leaving the interior living quarters visible to the outside.
Marshalltown is a city of 27,000 about 50 miles (80 kilometres) northeast of Des Moines.
