Devastating Tornado in US

A devastating storm system moved across the United States on Friday, spawning a slew of tornadoes that contributed to at least 28 fatalities in Indiana, Kentucky and Ohio, the CNN reports.

National Weather Service meteorologist John Gordon reported Friday afternoon the agency had about "half a dozen reports of tornadoes on the ground," as well as reports of "significant damage" -- making his comments before some of the worst twisters were reported.

"This is an enormous outbreak that's going on right now across Kentucky and the South," Gordon said. "It's crazy. It's just nuts right here."

At least 15 people were killed across Indiana, authorities said.

Aerial footage from CNN affiliate WLKY showed structures torn to shreds and large swaths of trees knocked down in Henryville, about 20 miles north of Louisville, Kentucky.
