Central Indiana was hit by a multi‑day storm system in mid‑August 2026 that produced historic rainfall, caused the White River and smaller waterways to surge past long‑standing records and left communities across the region coping with fatalities, evacuations, widespread rescues and major infrastructure disruption.
- Historic rainfall and downstream runoff drove the White River above century‑old records in parts of central Indiana, producing severe flooding in Indianapolis suburbs.
- At least six storm‑related deaths were reported and dozens of rescues and evacuations occurred across affected counties.
- Governor Mike Braun declared a statewide emergency and President Trump approved a FEMA emergency declaration to supplement local response.
What happened — the immediate facts
State and local officials reported at least six storm‑related deaths across Indiana after heavy rains beginning Aug. 11, 2026, and continuing through the week. Floodwaters inundated neighborhoods in Indianapolis and surrounding suburbs, submerging cars and reaching front doors in areas such as Ravenswood, Rocky Ripple and Broad Ripple, according to aerial and on‑the‑ground reporting.
Officials said some locations received between 6 and nearly 12 inches of rain over a two‑day stretch, and the White River crested at more than 24 feet in communities including Anderson and Noblesville — surpassing levels set in 1913, the National Weather Service reported. In Indianapolis the White River was projected to crest at 21.1 feet on Aug. 15, expanding flood risk downstream.
Rescue teams recovered more than 90 people and 45 pets from rising water along the White River, and authorities evacuated hundreds of residents in threatened neighborhoods and assisted‑living facilities. Local emergency managers described the event as “once‑in‑a‑lifetime” or ‘‘historic’’ flooding.
Federal and state response
Indiana Gov. Mike Braun declared a statewide emergency and said he spoke with President Donald Trump, who approved a Presidential Emergency Declaration to make federal disaster assistance available. FEMA described the aid as supplementing state, tribal and local response for “severe storms, straight‑line winds, tornadoes and flooding beginning on August 11, 2026, and continuing.”
FEMA assistance aims to support response and recovery actions but the agencies involved have not released an estimated damage total in the sources reviewed.
Where damage was concentrated and human toll
Officials reported storm‑related deaths in Marion County (Indianapolis), Delaware, Jennings, White, Porter and LaPorte counties, and additional fatalities were reported across the state. At least one victim’s body was found after an individual apparently tried to drive through floodwaters, according to sheriff’s deputies in Delaware County.
The most severe flooding was reported along the White River corridor from Hamilton County into Indianapolis’s northern suburbs, where levees and neighborhood flood protections were tested. Rocky Ripple residents organized sandbagging efforts to stem levee seepage when river levels rose over walls near Hohlt Park.
Infrastructure, power and public safety impacts
Storms caused widespread power outages across northwest and central Indiana and extensive wind damage in some areas: state officials cited gusts up to 99 mph in Gary during the storm system. Utility restoration work faced challenges; in Gary, one utility contractor’s vehicle was struck by gunfire while crews were working to restore power, temporarily pausing some operations while law enforcement coordinated additional security.
Local officials, including Indianapolis Mayor Joe Hogsett and Marion County emergency managers, urged residents to avoid floodwaters and to evacuate when ordered. National Guard vehicles assisted in rescue operations.
Weather outlook and continuing risks
Forecasters warned that the danger had not passed. Flash‑flood watches and warnings were in effect across central Indiana, and the National Weather Service advised that additional showers and thunderstorms could move into the area, threatening to raise streams, creeks and rivers already swollen by recent rain. Meteorologists also cautioned that repeated downpours on saturated ground can produce rapid runoff and flash flooding, and that isolated tornadoes remained possible.
Timeline of key developments
- Beginning Aug. 11, 2026 — Region receives multiple rounds of strong storms that bring heavy rain, straight‑line winds and isolated tornadoes.
- Over the next 48 hours — Some areas record between 6 and nearly 12 inches of rain; rivers and creeks rise rapidly.
- By Aug. 15 — White River crests above century‑old records in Anderson and Noblesville; evacuations and neighborhood rescues increase in Indianapolis suburbs.
- Aug. 15–16 — Gov. Mike Braun declares a statewide emergency; President Trump approves a Presidential Emergency Declaration and FEMA announces federal assistance availability.
What remains unresolved or unclear
Sources differ slightly on the reported number of deaths (reports cite at least five, six or seven fatalities in different updates). State and federal authorities had not released a consolidated statewide death toll or a full estimate of economic damage in the material reviewed. Similarly, a schedule for complete utility restoration varies by report: one utility projected near‑term restoration targets for most customers, while localized outages and safety concerns in Gary briefly impeded repairs.
Practical implications for residents
- Authorities warned people to avoid floodwaters, not to drive through flooded roadways and to follow evacuation orders where issued.
- Residents in flood‑threatened neighborhoods should monitor local emergency briefings for shelter locations, sandbag distribution and road closures.
- Those without power should follow utility advisories and report outages; crews may pause work in areas where responder safety is at risk.
Context and comparison
Officials characterized the event as historic, noting that river crests exceeded levels recorded in 1913 in some locations. The combination of intense localized rainfall and downstream runoff produced flooding in urban and suburban corridors that are vulnerable when upstream basins see extreme precipitation over short periods.
“This is one of those once‑in‑a‑lifetime type floods,” Marion County emergency management leadership told The Associated Press, according to local reporting.
