(WISH) - National Weather Service teams are out assessing storm damage in southern Indiana and already have determined that all of the tornadoes that struck Friday were very powerful storms.
Two separate tornado-producing super cell thunderstorms were tracked over southern Indiana and into Kentucky, NWS said. The two storms followed essentially the same path between the towns of Pekin and Henryville, about 10 minutes apart.
The first storm produced EF-4 tornadoes, with winds of 166 to 200 mph, that hit the towns of Henryville and Chelsea on Friday. In Henryville, winds reached 175 mph.
EF-3 tornadoes, with winds of 136 to 165 mph, hit the towns of Holton and New Pekin. In Holton, winds reached 145 mph.
An EF-2 tornado was also preliminarily identified in far southwestern Indiana, in Posey County.
Damage assessment is continuing throughout the area.
In Henryville , north of Louisville, where the town's school complex was decimated, there will be no classes this week. The town is just beginning the process of recovery.
In nearby Marysville, where specific storm strength and type has not yet been determined, officials are working to keep out-of-towners mostly out of the area to give families whose homes were destroyed time to sort through the rubble.
The official death toll across Indiana was lowered to 12 on Sunday, according to The Associated Press. The overall death toll from Friday's storms in five states stood at 36 as of about 10:30 a.m. Sunday.
Hoosiers are being hit with the coldest weather statewide in about three years, and officials are warning drivers about black ice.
Mintonye Elementary School may be ready to open in August, but Southwestern Middle School won't be ready. That's the preliminary assessment Superintendent Scott Hanback told the Tippecanoe School Corporation school board Wednesday evening.
State police and the Indiana Department of Transportation say public safety is being endangered by metal scrappers.
