Illinois’ 200-tornado year is testing how the state prepares for severe weather

The Aug. 11-12 derecho that crossed northern Illinois has become both a recovery challenge and a marker of an unusually active tornado year.

The storm brought tornadoes, widespread power outages, downed trees, property damage, flooding threats and transportation disruptions across the Chicago region and south suburbs. An Aug. 13 Axios Chicago update said five tornadoes had been confirmed from the storm, pushing Illinois above 200 tornadoes in 2026. That statewide count is a developing figure attributed to the report, not a final National Weather Service certification.

As communities document losses, the Illinois Emergency Management Agency and Office of Homeland Security is accepting non-emergency property-damage reports from residents. Local governments and eligible organizations have a separate process for documenting damage, costs and service impacts that could support additional state action or a request for federal assistance.

What happened in northern Illinois

The fast-moving storm system was identified in news coverage as a derecho, a long-lived windstorm capable of producing widespread damaging winds. Associated Press reporting described tornadoes, flooding threats, power outages and other storm damage across the Midwest, while Illinois-specific reporting focused on the Chicago area and south suburbs.

Initial reporting identified three tornadoes tied to the storm. By Aug. 13, Axios Chicago reported that five had been confirmed. The later count also moved Illinois past the 200-tornado mark for the year, according to Axios.

More than 370,000 customers lost power after the storms, Axios reported, with ComEd and NIPSCO crews working on restoration at the time of that report. Outage totals and restoration status can change quickly as crews assess damage and make repairs.

What residents should report

IEMA-OHS has activated a damage-assessment survey for people to report damage to homes and property. The agency says the survey is for non-emergency needs and that responses are not monitored in real time. Anyone facing an immediate threat should call 911 or contact local emergency authorities.

Residents should photograph damage before making repairs when it is safe to do so. Useful records include before-and-after photos, repair estimates, bills, invoices, receipts and contractor information. Homeowners and renters should also contact their insurers and follow local instructions about debris, utility hazards, road closures and emergency assistance.

A damage report does not automatically qualify an individual for state or federal financial assistance. IEMA-OHS says damage assessment helps emergency managers understand the extent of harm, prioritize response and support possible disaster declarations and recovery funding.

What local governments must preserve

Counties, municipalities, townships, school districts, special districts and other eligible organizations have a separate responsibility. Under IEMA-OHS guidance, potential applicants must identify damage, costs and impacts, report costs by county and category of work, and submit information through the state and local emergency-management process.

Documentation can include location maps, photographs, estimates, bills, invoices, receipts, equipment and labor records, and contract documents. Organizations also report impacts such as shelters opened, businesses closed and schools closed.

This initial reporting supports a later preliminary damage assessment. Federal, state and local representatives use that process to collect information about damages, costs and impacts. IEMA-OHS says the assessment is typically used as a basis for a governor’s request for a major disaster or emergency declaration, but it does not guarantee that a declaration will be requested or approved.

What assistance could look like

FEMA’s Public Assistance program may provide federal assistance to states, local governments and certain private nonprofit organizations for debris removal, emergency protective measures and restoration of eligible public facilities after a presidential major-disaster or emergency declaration.

If a county is designated for Public Assistance, an eligible organization generally must submit a Request for Public Assistance to IEMA within 30 days of the declaration date or the date its county was designated. After a Recovery Scoping Meeting, applicants have 60 days to identify and report damages to FEMA under the process described by IEMA-OHS. Those deadlines apply to the Public Assistance process, not automatically to every resident or every recovery program.

For approved project worksheets, the federal share is no less than 75% of eligible costs, while applicants are generally responsible for the remaining nonfederal share, usually 25%. Eligibility, project scope and reimbursement depend on formal FEMA and IEMA review and documented costs.

No derecho-specific award verified as of Aug. 14

The reviewed official Illinois materials did not show a new disaster proclamation or FEMA award specifically tied to the Aug. 11-12 derecho as of Aug. 14. The available guidance instead describes the assessment and declaration steps that would precede potential Public Assistance.

For residents, the immediate priorities are to preserve evidence, contact an insurer, submit the IEMA-OHS report for non-emergency damage and follow local instructions. Public agencies and eligible organizations should report damage by county and category while preserving records of labor, equipment, contracts and other costs.

The next major decision is whether the damage assessments support additional state action or a request for federal assistance. Reporting damage is part of assessment and recovery planning, not a promise of reimbursement.
