NWS-confirmed tornado near Moronts, Putnam County, Illinois – Aug 21, 2026

A National Weather Service-confirmed tornado touched down near Moronts in Putnam County, Illinois on the evening of August 21, 2026, part of a fast-moving mesoscale convective system (MCS) that swept through north-central Illinois during the early evening hours. The event was logged by NWS Davenport (WFO DVN) at approximately 7:15 PM CDT, with the tornado positioned 1 mile north-northeast of Moronts at coordinates 41.30°N, 89.29°W — approximately 79 miles west-southwest of Oak Brook.

Confirmation came through video posted to social media and attributed to NWS Davenport in the Storm Prediction Center’s official storm reports. The same MCS had produced a confirmed tornado in Lee County earlier that day, with cells continuing to track southeastward through the region. Communities in and around Putnam County — including Princeton, Hennepin, Granville, and Bureau — fell within the affected corridor and may have experienced damaging winds, large hail, and heavy rainfall associated with this event.

What the National Weather Service Confirmed

The NWS Weather Forecast Office in Davenport, Iowa (WFO DVN) is the issuing authority for this event. Based on data attributed to NWS Davenport in the Storm Prediction Center’s official storm reports, the following facts were recorded:

• Date and time: August 21, 2026, at approximately 7:15 PM CDT
• Location: 1 mile north-northeast of Moronts, Putnam County, Illinois
• Coordinates: 41.30°N, 89.29°W
• Confirmation method: Video posted to social media, as cited in SPC official storm reports attributed to NWS Davenport
• EF-scale rating: No Fujita or Enhanced Fujita rating had been assigned at the time of initial reporting
• Storm context: Associated with the same evening MCS that produced a tornado in Lee County earlier on August 21, with individual cells tracking southeastward through north-central Illinois

An official NWS damage survey may follow in the coming days, which could result in an EF-scale rating and additional details regarding the tornado’s path, width, and duration. For official updates, monitor weather.gov directly. No injuries or fatalities were confirmed in the initial storm reports. Allied Emergency Services will update community resources as official information becomes available.

What Homeowners in Princeton, Hennepin, Granville, and Bureau Should Check Now

Even when a tornado is confirmed at a specific point, the broader MCS surrounding it can produce straight-line winds, large hail, and heavy rain across a much wider area. Homeowners in Princeton, Hennepin, Granville, and Bureau — as well as surrounding Putnam County communities — should conduct a thorough property inspection as soon as conditions are safe to do so.

Roof

• Walk the perimeter of your home and observe visible roof surfaces from the ground. Do not climb onto your roof unless you are a trained professional.
• Look for missing, lifted, or curled shingles. Hail impacts often leave circular bruising or soft spots on asphalt shingles that are easier to feel than see.
• Check ridge caps, pipe boots (the rubber collars around plumbing vents), and flashing around chimneys and skylights — these are common failure points after high-wind events.
• If you have a metal roof or standing-seam system, look for dents or displaced panels along seams and ridges.

Siding and Exterior

• Inspect vinyl, fiber cement, or wood siding for cracks, holes, or impact marks on all four sides of your home.
• Hail strikes on vinyl siding often leave circular dents or cracks, especially on south- and west-facing elevations that face the direction of storm travel.
• Check window frames, shutters, and exterior trim for damage. Inspect caulking around windows and doors for gaps that could allow water intrusion going forward.

Gutters and Downspouts

• Bent, dented, or detached gutters are among the most visible signs of hail or wind damage. Look for dents along the gutter face and end caps.
• Confirm that downspouts are still connected and properly directing water away from your foundation.
• Gutters filled with granules — the gravel-like coating shed from damaged asphalt shingles — are a strong indicator of roof damage even before you inspect the roof surface itself.

Trees and Landscaping

• Survey trees near your home for broken limbs, cracked trunks, or uprooted root systems. Any tree posing a fall risk to your structure should be assessed by a professional before the next weather event.
• Check fences, outbuildings, sheds, and detached garages for structural damage or displacement.

Interior Water Intrusion

• Inspect attic spaces (if safely accessible) for daylight visible through the roof deck, wet insulation, or active dripping.
• Check upper-floor ceilings for watermarks, bubbling paint, or soft spots that could indicate water infiltrating from above.
• Look along interior walls near windows and exterior doors for streaking, dampness, or peeling paint.

If you find any of these signs, document everything before disturbing the area.

If You Find Damage

Prioritize safety first. Do not attempt repairs, roof climbing, or storm debris removal on your own. If your home has structural damage, contact your local fire department or building department before re-entering. Gas line issues, electrical hazards, and compromised structural members are not always visible to the untrained eye.

Document before you touch anything. Before any cleanup or temporary repairs begin, photograph and video every area of visible damage — exterior and interior. Time-stamped documentation is essential for the insurance process. Photograph impact marks on siding, gutters, AC condenser fins, and any wood decking or fencing nearby, which often show hail evidence more clearly than roof surfaces.

Secure your property with temporary protective measures. If you have active roof damage with exposed decking, temporary tarping prevents secondary water damage from compounding your loss. Most homeowners insurance policies expect you to take reasonable steps to prevent further damage — and this can and should happen before a full assessment is completed.

Notify your insurance carrier promptly. Open a claim as soon as possible. Your insurer will assign an adjuster to evaluate the damage. As a licensed restoration contractor, Allied Emergency Services can document your damage thoroughly, prepare a detailed repair estimate, and meet with your insurance adjuster on-site — however, Allied does not negotiate, settle, or adjust insurance claims on behalf of homeowners. Those services fall within the scope of a licensed public adjuster.
