They're now worried what will come next
It's expected to be another challenging day for people in Merrillville, Indiana as they clean up after weathering an EF-2 tornado with winds up to 135 miles-per-hour.
The storm caused extensive damage to hundreds of homes and local structures.
Fortunately, no serious injuries have been reported.
NIPSCO is still working to restore service to those who lost power. Most of those impacted are in Merrillville.
Joe and Marlene Trevino survived the storm, but lost their home to the tornado and say more bad weather will make it even harder to recover.
"I came out of our garage, and all the debris are all over, and I can't believe our house is gone just like that, you know? I'm just under three minutes-- gone," Marlene said.
"Things were tough and tight as it was, and then now we got this," Joe said.
Local officials are obviously on alert as well.
There's a tornado recovery website at merrillville.in.gov/tornado, is available for people in Merrillville with helpful resources, especially as this next round of storms heads our way.
