Indiana Flood Warning: Midwest braces for more dangerous flooding and storms

Severe weather is refusing to give the Midwest a break.

After catastrophic flooding swept across eastern Indiana, another round of storms is expected Thursday, threatening to bring fresh flooding from Iowa and northern Illinois into parts of the Ohio Valley that are already struggling with swollen rivers and saturated ground, reported CNN.

The latest storms come after a deadly derecho battered the region Tuesday, leaving widespread destruction and power outages. Forecasters warn that the threat of dangerous flooding could continue through Friday before gradually shifting farther north.

Eastern Indiana Faces More Flooding

Some communities in eastern Indiana endured extraordinary rainfall Wednesday, with New Castle receiving more than 11 inches in just 32 hours. The rainfall produced conditions comparable to a 1-in-1,000-year flood event, overwhelming roads, homes and drainage systems.

Cambridge City reported catastrophic flooding as water poured through large parts of the community. Video obtained by CNN showed floodwater reaching the windows of homes while vehicles were nearly submerged.

Officials urged residents in vulnerable parts of Cambridge City to evacuate, Wayne County Emergency Management Agency spokesperson Todd Harmeson told CNN. Rescue crews used boats to reach people stranded by floodwater as many roads became impossible to navigate.

The town also remains under a boil-water advisory, with officials warning that some residents could be without utilities for days.

Nearby New Castle was also hit hard. Floodwater reached waist-deep levels in some areas, Kendra Blankenship, an assistant to the city's mayor, told CNN. City buses were used to transport residents escaping the flooded areas to a temporary shelter.

Muncie Evacuations Underway

Flooding also spread farther north into Muncie, where authorities worked to evacuate an area containing roughly 200 homes.

Several residents were rescued by boat, while emergency crews continued checking affected neighborhoods for people who needed help. Roads across the city were flooded, disrupting normal activity and forcing officials to postpone the first day of school.

Although conditions stabilized somewhat by Wednesday night, authorities continued to deal with water rescues, Muncie Fire Chief Daniel Burford told CNN.

Indiana Gov. Mike Braun said numerous roads had been washed out and emergency responders had carried out a large number of water rescues across the hardest-hit communities.

Rivers Could Keep Rising

The danger is not expected to disappear when the heaviest rain moves away.

At least four rivers in eastern Indiana are forecast to reach major flood stage into Thursday. That means some communities could see flooding worsen or remain severe even after rainfall begins to ease.

The combination of saturated soil, overflowing waterways and additional storms creates a particularly dangerous setup. Areas that escaped the worst of Wednesday's rainfall could also face problems if repeated storms move over the same locations.

New Storms Target Iowa, Illinois and Ohio

Another storm system was developing over Nebraska early Thursday and was expected to move into Iowa around daybreak before spreading toward the Upper Midwest.

The biggest concern is repeated rainfall. A stalled weather front, combined with a surge of moisture, could allow thunderstorms to track across the same areas several times Thursday.

Forecasters have placed parts of Iowa, northern Illinois, Indiana and Ohio under an elevated risk for flooding rainfall. Some forecast models indicate that isolated areas could receive 3 to 6 inches or more if storms repeatedly pass over the same locations.

Rain and thunderstorms could continue into Friday across portions of the Midwest, Ohio Valley and Appalachians. The focus of the flooding threat is then expected to shift toward the Upper Mississippi Valley.

Midwest Power Outages Mount

The severe weather has also left hundreds of thousands of customers without electricity.

Nearly 275,000 homes and businesses in Indiana were without power Thursday morning, while the total number of outages across the Ohio Valley remained above half a million.

The outages follow Tuesday's derecho, which caused widespread damage across Illinois, Indiana and Ohio. A northern Indiana utility described the event as the largest outage emergency in its history.

Deadly Derecho Adds to Crisis

The flooding followed a destructive line of storms that swept across the Midwest Tuesday.

A 4-year-old boy was killed in southeastern Indiana after a tree fell onto a home in Geneva Township, according to the Jennings County sheriff's department.

Another person died in Portage, Indiana, following what appeared to be an explosion and house fire after the derecho passed through the area. Investigators suspect fallen trees may have damaged natural gas lines, although the cause remains under investigation.

Thursday's storms are not expected to produce another derecho on the scale of Tuesday's event. However, isolated damaging wind gusts and large hail remain possible as thunderstorms move through parts of Iowa and the Upper Midwest.

Extreme Rainfall Raises Flood Risk

The latest flooding is part of a broader pattern of increasingly intense rainfall events. As the atmosphere warms, it can hold more moisture, providing storms with additional fuel and allowing them to release heavier bursts of rain.

For communities already dealing with flooded homes, damaged roads and rising rivers, even another relatively short period of intense rainfall could quickly create new emergencies.

The Midwest's punishing stretch of weather is therefore far from over. While the most severe threat is expected to diminish later in the week, residents across the flood-hit Ohio Valley and parts of the Upper Midwest remain at risk as another round of storms moves in Thursday.
