The National Weather Service sent crews Sunday to survey the hardest-hit areas in IL, which included Taylorville, 25 miles southeast of Springfield, Springfield's State Journal-Register reported.
One of the towns hardest hit was Taylorville, about 25 miles southeast of Springfield.
The storms wrecked houses, downed power lines and pulled up trees by their roots.
Firefighters from several surrounding towns were called in to help as first responders went door-to-door looking for anyone stuck or injured.
More than 1,300 homes are without power after destructive tornadoes swept through the South and Midwest and injured at least 20 people.
Gov. Bruce Rauner activated the State Emergency Operations Center in response to the storms. Damage surveys for the two tornadoes are ongoing but officials said dozens of homes were damaged.
"There were several people who were initially trapped in their homes due to damage initially but were rescued", Crews said. "Internet service, phone service, the ability to monitor the weather, the ability to track resources and things like that, so that's the type of support that asset will provide", said Buckingham.
Weather service meteorologist Chris Miller told The Associated Press on Sunday the agency was able to give Taylorville an advanced warning of 41 minutes that the powerful tornado was headed the community's way. "I know of one house that had major damage", she added.
The National Weather Service reportedly deployed teams on Sunday to assess the damage and measure the strength of the twisters. A tornado also struck a Georgia naval base, flipping a Coast Guard ship and injuring at least one person.
