Residents in parts of the Midwest are assessing damage after tornadoes touched down, leaving mass destruction behind late Monday. The AP writes, “A rapid-fire line of apparent tornadoes tore across Indiana and Ohio overnight, packed so closely together that one crossed the path carved by another.”

NPR called the series of tornadoes catastrophic:

Officials in Dayton and nearby communities are still searching for potential victims, after intense storms wreaked havoc.

“The first tornado warning went out one minute before 9 p.m. in Wayne County, West of Richmond. The last warning was issued a few minutes before 2 a.m. in Hocking County,” member station WYSO reports. “In all, officials issued 36 tornado warnings, one flash flood warning, and recorded multiple instances of golf ball-sized hail in the Dayton area Monday night.”

Homes are leveled and debris is so bad on the roads, that snow plows are clearing the damage away.
