A destructive August 11 derecho brought widespread 70–100+ mph winds, tornadoes, damaged transmission and distribution equipment, fallen trees, flooding and mass outages across northern Illinois and Northwest Indiana. The two sides of the state line are now in different stages of recovery: ComEd had restored about 99% of customers affected by the August 11–12 storms by August 15, while NIPSCO still reported 93,000 customers without power at 11 a.m. CT on August 18.
The most important numbers, with their timestamps and geographic scope.
| Area | Verified status | What it means |
|---|---|---|
| NIPSCO / Northern Indiana | 93,000 customers without power at 11 a.m. CT, Aug. 18. NIPSCO reported 269,000 restorations since the start of the event and 370,000 total outages from Aug. 11–18 as repeated storms caused new interruptions. | The outage remains a major regional emergency. NIPSCO said the original Aug. 11 storm affected about 301,000 customers — more than 60% of its electric customers. |
| Gary, Indiana | Gary remained one of the hardest-hit communities. CBS Chicago reported 27,000 Gary homes still without electricity on Monday, Aug. 17. The City of Gary said some large service areas were still undergoing damage assessment. | Gary's count is an Aug. 17 snapshot, not a claim that 27,000 were still out at the exact moment this page was generated. |
| ComEd / Northern Illinois | ComEd said approximately 99% of customers impacted by the Aug. 11–12 storms had been restored by Aug. 15, after nearly 410,000 customer outages. | The original Illinois derecho restoration was largely complete before additional severe weather produced new outages. ComEd's current outage map was showing roughly 10,000 affected customers when checked Aug. 18. |

The National Weather Service classifies the core event as a derecho: a long-lived, widespread damaging wind event associated with thunderstorms.
Tuesday, August 11, 2026: a derecho crossed parts of the Midwest and Ohio Valley. NWS Chicago documented widespread straight-line winds of 70 mph to locally over 100 mph from northeastern Illinois into northwestern Indiana.
Gary recorded one of the strongest measured gusts: 99 mph at Gary/Chicago International Airport. NWS also confirmed six tornadoes in its area of responsibility during its initial post-event analysis, including tracks through parts of the south and southwest Chicago suburbs and Northwest Indiana.
The electrical damage was not limited to neighborhood wires. NIPSCO described damage to transmission and distribution systems across its footprint. ComEd likewise reported broken poles, damaged equipment and downed wires, including transmission-system damage in hard-hit Southland communities.
There is no credible evidence that the prolonged regional outage was caused by a cyberattack, intentional shutdown, data center, or political action. The documented cause is destructive severe weather followed by extensive infrastructure repair work and additional storms.
The most severe and persistent outage burden is on the Indiana side of the metro area.
CBS Chicago reported 27,000 Gary homes without electricity on Monday, Aug. 17. ABC7 documented residents using coolers and ice for food and traveling elsewhere to charge phones and cool down.
Prolonged outageDyer's town manager told CBS Chicago the wastewater treatment plant had been running continuously on a generator while roughly half the town remained without power.
Infrastructure strainMore than 5,000 people in East Chicago were reported without power early Aug. 18 after some customers had previously regained service. A utility-equipment fire was investigated, but NIPSCO had not confirmed that it caused the new outages.
Re-interruptionLocal reporting documented long lines for gasoline and residents searching widely for generators as power failures affected homes, businesses and operating gas stations.
Supply pressureFor many households, the outage has disrupted basic routines well beyond lighting. Families are relying on vehicles and portable power for phone charging, moving food into coolers, conserving bottled water, checking on older relatives, and spending more time outdoors as homes remain without normal cooling and electrical service.
These conditions show how a prolonged outage can quickly become a household logistics problem involving food, communication, transportation, heat exposure, and care for vulnerable family members.
The Chicago area was hit hard too, but ComEd's August 11–12 restoration progressed substantially faster.
ComEd reported nearly 410,000 customer outages after the August 11–12 storms. The most significant damage was concentrated in its southern service region, including Homewood, Flossmoor, Lansing, Chicago Heights, Mokena, Tinley Park, Joliet, Ford Heights, Glenwood and Lynwood.
By August 15, ComEd said it had restored approximately 99% of customers affected by those storms. The utility deployed more than 4,500 personnel, contractors and mutual-assistance crews during the response.
That does not mean Northern Illinois has had no further outages. Additional severe weather can create new outages after restoration from the original event. This is why a “current outage” number should not be confused with the count tied specifically to the August 11–12 derecho.
Multi-day power loss creates health, food, transportation, communications and household-security pressures.
Residents interviewed in Gary described empty refrigerators and spoiled groceries after days without refrigeration.
Homes without air conditioning can become dangerously hot, especially for older adults, infants and people with medical vulnerabilities.
Extended outages can affect CPAP machines, oxygen concentrators, refrigerated medications and other electrically powered medical needs.
Power outages can close gas stations while generator demand simultaneously increases fuel consumption, creating long lines and localized shortages.
Dead phone batteries, disrupted internet service and weak cellular coverage can make it harder to receive restoration updates or reach assistance.
Water, wastewater, traffic signals and other municipal systems can shift to generators or degraded operations when utility power is unavailable.
Claims circulating during a crisis should be separated from documented facts.
| Claim | Finding | Evidence |
|---|---|---|
| Gary/NW Indiana suffered a historically large outage. | Verified | NIPSCO says the Aug. 11 storm affected about 301,000 customers, more than 60% of its electric customers, making it one of the largest outage events in company history. |
| Gary recorded winds near 100 mph. | Verified | NWS Chicago recorded a peak measured 99 mph gust at Gary/Chicago International Airport. |
| Many Gary residents have gone nearly a week without power. | Verified | ABC7 and CBS documented residents still without power on Aug. 17–18, including 27,000 Gary homes reported out on Aug. 17. |
| People have been scrambling for generators and gasoline. | Verified | Multiple local reports documented generator demand and long gasoline lines across Northwest Indiana. |
| People are breaking into homes and cars specifically to steal generators. | Not verified | I did not find sufficiently reliable reporting or an official law-enforcement source establishing this as a widespread pattern. It should not be published as fact without police reports or other primary documentation. |
| The national news is not covering the disaster. | False / overstated | The event has been covered by national outlets including the Associated Press and Reuters, in addition to ABC7 Chicago, CBS Chicago, NBC Chicago and other regional news organizations. |
| The outage was deliberately caused. | Unsupported | Official weather and utility sources attribute the event to destructive storms, tornadoes, downed trees and extensive transmission/distribution damage. |

NIPSCO electric emergency/outage line: 1-800-464-7726.
ComEd: 1-800-334-7661. Never approach a downed power line; assume it is energized.
Never operate a portable generator inside a home, garage, basement, shed or other enclosed/partially enclosed space. Keep it outdoors and away from doors, windows and vents. Carbon monoxide is colorless and odorless. Do not connect a generator directly to household wiring unless an appropriate transfer system has been installed by a qualified professional.
Large storm outages are repaired in layers, not simply house by house.
Make hazards safe. Crews identify downed energized lines, blocked roads, unstable poles and damaged substations.
Repair transmission. High-voltage lines and major substations must work before many local distribution circuits can be energized.
Restore critical facilities and large groups. Utilities generally prioritize repairs that safely restore the greatest number of customers and critical services.
Repair neighborhood circuits. Broken poles, transformers, conductors and tree damage can require extensive field work.
Address individual service damage. A home may remain out after the surrounding neighborhood is restored if its service equipment or nearby secondary line is damaged.
That is different from asking whether it is being covered at all.
It is factual to say national and regional media have covered the storm. Associated Press and Reuters both reported on the Midwest outages, and Chicago television stations have continued daily reporting from Northwest Indiana.
It is also reasonable to ask whether the scale and duration of the Northwest Indiana crisis is receiving enough sustained national attention. That is an editorial question, not a factual claim that there has been “no national coverage.”
A precise formulation is: “Why has a prolonged outage affecting tens of thousands of Northwest Indiana residents not received more sustained national attention?”
