Damage also was reported in Lafayette and Kokomo. A state of emergency was declared for Howard County, particularly Kokomo, Russiaville and Greentown, until 6 a.m. Monday. Pedestrian and vehicular traffic is prohibited until that time.
"It's a very dangerous storm, and it's only about halfway across the state right now," Pence said.
The initial line of storms traveled at a ground speed of 50-70 mph, Pence said.
The National Weather Service reported a tornado damaged several houses in Washington.
A teacher was injured when a storm heavily damaged Southwestern Middle and Grade School in southern Tippecanoe County, Indiana State Police Sgt. Kim Riley said.
"The gymnasium is basically gone," and parts of the roof had been blown off, too, Riley said.
"It's very chaotic," Riley said.
Tree branches were blown into concrete walls there, said Riley, who went to the scene.
A small barn was blown across Indiana 28 in Montgomery County, and trees and power lines were down across the area, Riley said.
