DES MOINES, Iowa – A flurry of unexpected tornado swept through central Iowa, injuring at least 17 people, flattening buildings in the three cities and forcing a hospital evacuation.
Residents — and even weather forecasters were surprised Thursday when the tornadoes struck Marshalltown, Pella and Bondurant. Ten people were injured in Marshalltown and seven in a factory in the area of Pella, but no deaths reported.
The National Weather Service meteorologist Alex Krull says forecasting models had turned out to be only a small chance of strong thunderstorms. Krull says if anything, meteorologists expected large hail, strong storms developed.
Marshalltown turned out to be the hardest hit. Brick walls collapsed in the streets and the roofs were blown off buildings. The only hospital in Marshalltown was damaged and the patients were transferred.
