Fallen trees and power lines delayed emergency crews as investigators worked to determine what caused the blast and fire.
PORTAGE, IN — One person died after a suspected home explosion and fire Tuesday as destructive storms swept through Portage, leaving roads blocked by fallen trees and power lines and slowing emergency crews trying to reach the scene.
Officials said reports of the incident came in around 12:20 p.m. Aug. 11, shortly after the severe weather moved through the northwest Indiana city. The home was leveled, but authorities had not determined what caused the apparent explosion. Portage officials said the storm may have played a role, though investigators cautioned that confirming a connection could take days or longer.
Police and firefighters faced unusually difficult conditions while responding. Trees, utility lines and other debris blocked roads throughout Portage, forcing some police officers to park about a mile from the scene and continue through neighborhoods on foot. Fire crews also had to search for a route around storm damage before they could reach the burning property.
Portage Fire Chief Chris Crail said crews went to work immediately once they reached the home. Authorities initially received a report of a fire on the city’s north side, along with reports of an explosion. Officials said the appearance of the destroyed home was consistent with a powerful blast, but the cause remained part of the investigation.
Neighbors along Harrison Avenue described hearing a sudden explosion after the worst of the storm had passed. Several residents had gone outside to check damage and nearby homes. One neighbor told ABC7 Chicago that he noticed what he believed was the smell of gas shortly before the explosion. That account had not been established by investigators as the cause of the blast.
The homeowner told ABC7 that he had left for a medical appointment before the explosion. Neighbors said another resident remained at the home. Authorities confirmed one death but had not publicly released the victim’s identity in the reports available early Wednesday. No official determination about the sequence or cause of the explosion had been announced.
The fatal incident came amid widespread destruction across Portage and other parts of northwest Indiana. Officials reported numerous fallen trees, damaged vehicles, blocked streets, power outages and some gas leaks. Several people in Portage suffered minor injuries from falling trees and other storm damage, but officials said no additional serious injuries had been reported in the city.
The severe weather was part of a powerful system that crossed Illinois and Indiana on Tuesday. The Associated Press reported that more than 600,000 customers lost electricity across the two states, with Lake and Porter counties among the hardest-hit areas. Preliminary information from the National Weather Service’s Storm Prediction Center indicated the long-lived windstorm qualified as a derecho, a widespread straight-line wind event capable of producing extensive damage.
Portage Mayor Austin Bonta issued an emergency proclamation after the storm. City officials established an emergency center at City Hall and urged residents to limit unnecessary travel while police, firefighters, utility crews and public works employees cleared hazards. Portage Township Schools also canceled the first day of classes scheduled for Wednesday as officials assessed damage to campuses and surrounding roads.
National Weather Service survey teams were expected to examine damage in Lake and Porter counties as recovery efforts continued. Investigators were also working to determine the cause of the fatal fire and suspected explosion. Authorities had not confirmed early Wednesday whether storm damage, a gas leak or another factor caused the home to explode.
