NWS-confirmed damaging winds sweep Kosciusko, Noble, Allen & Clinton Counties IN

On the evening of September 15, 2026, a fast-moving line of thunderstorms swept northeast across northern and central Indiana, leaving a trail of downed trees, severed power lines, and storm-damaged properties in its path. The National Weather Service offices in Northern Indiana (NWS IWX) and Indianapolis (NWS IND) confirmed damaging thunderstorm wind events across four counties — Kosciusko, Noble, Allen, and Clinton — between approximately 6:43 PM and 9:30 PM CDT, a window that touched communities from the lake country of north-central Indiana to the farmlands approaching the state’s midsection.

Residents in Syracuse, Warsaw, Rome City, Albion, Wallen, Fort Wayne, and Frankfort felt the storm’s reach — whether through falling limbs, flickering power, or the sound of wind accelerating through neighborhood canopies. The storm has moved on, but the damage it left on and around homes can worsen quickly if not identified and addressed. What follows is a summary of what NWS confirmed and what property owners in affected communities should do next.

What the National Weather Service Confirmed

The following events are drawn from Local Storm Reports filed by NWS Northern Indiana (IWX) and NWS Indianapolis (IND) for the evening of September 15, 2026. All four events were attributed to a progressive convective line — an organized band of thunderstorms — that tracked northeast across northern and central Indiana during the roughly three-hour window.

Kosciusko County — Near Lake Wawasee

NWS IWX confirmed numerous trees downed in the Lake Wawasee area during the early evening. The lake region, which includes the community of Syracuse and draws many second-home and lakefront property owners, was squarely in the storm’s path. Downed trees are a primary driver of hidden roof damage — large limbs can compromise shingles, roof decking, and gutters even when they do not fully penetrate the structure. Warsaw and surrounding Kosciusko County communities are also within the zone where residents should inspect their properties.

Noble County — Near Knapp Lake

NWS IWX confirmed thunderstorm wind damage in Noble County, supported by video evidence showing 2-to-4-inch tree limbs falling near Knapp Lake. Limb failures of this caliber — branches thick enough to cause structural impact on impact — are characteristic of wind gusts well above the nuisance threshold. Noble County communities including Rome City and Albion are within the affected area. Homeowners there should give particular attention to rooflines, siding panels, and any trees with canopy hanging close to structures.

Allen County — Near Wallen and the Fort Wayne Area

NWS IWX recorded a thunderstorm wind gust of 65 mph near Wallen in Allen County. This measurement was corroborated by a trained storm spotter in the area and confirmed through KSMD anemometer data, making it one of the more precisely documented wind events associated with this storm system. At 65 mph, wind loads are sufficient to displace roofing materials, tear siding panels from wall sheathing, and dislodge gutters and downspouts. Wallen is located northeast of Fort Wayne, and residents throughout the Fort Wayne metro corridor should not assume they were spared simply because visual damage isn’t obvious from the street.

Clinton County — Near Antioch and the Frankfort Area

NWS Indianapolis (IND) confirmed that multiple trees and power lines were downed by thunderstorm winds near Antioch in Clinton County. Frankfort, Clinton County’s county seat, is among the communities where homeowners should conduct a thorough post-storm property inspection.

What Homeowners in Affected Towns Should Check Now

Whether you’re in Syracuse, Warsaw, Rome City, Albion, Wallen, Fort Wayne, or Frankfort, the same convective line moved through your region. Even properties that appear intact from the curb can carry damage that becomes costly if left unaddressed through fall and winter weather. Here is what to inspect once conditions are safe.

Roof

• Walk the perimeter of your home and examine the roofline from ground level. Look for missing, lifted, or visibly displaced shingles — even a single displaced tab can allow water to infiltrate the decking below.
• Check ridgecaps and hip edges, which are among the first components wind pries loose.
• Look for exposed roof decking (visible bare wood), granule loss on asphalt shingles, or lifted flashing around chimneys, plumbing vents, and skylights.
• Use binoculars for a closer ground-level look. Do not climb onto your roof for inspection — that is a job for a trained inspector with proper safety equipment.

Siding and Exterior

• Walk each elevation of your home and look for cracked, dented, buckled, or missing siding panels.
• Inspect fascia boards, soffits, and exterior trim for separation or gaps where wind-driven water can work its way in.
• Check caulking and weatherstripping around all windows and exterior doors for new gaps or cracking introduced by the storm.

Trees and Landscaping

• Assess any tree near your home for split limbs, leaning trunks, or partially uprooted root systems. A tree that survived the storm structurally compromised poses a future risk.
• A large limb suspended in a tree’s canopy — sometimes called a “widow maker” — is a serious safety hazard. Do not attempt to dislodge or remove it yourself; contact a licensed arborist or restoration contractor.
• Clear debris from foundation vents, window wells, and surface drainage paths to prevent water from pooling against your foundation.

Gutters and Downspouts

• Check gutters for pulling away from the fascia, visible bending, or open seams at joints.
• Inspect downspout connections and splash extensions — wind events commonly displace these, redirecting drainage water toward the foundation.
• Look for an unusual accumulation of granules in your gutters. Shingle granules flushing into gutters after a wind event can be an early indicator of roofing damage that warrants professional evaluation.

Water Intrusion

• If it is safe to access, check your attic space for daylight or any sign of moisture within 24 to 48 hours of the storm.
• Inspect ceilings and upper interior walls for water stains, bubbling paint, or damp patches that weren’t there before.
• Check around all exterior windows and doors for signs of water infiltration at the frame or sill.
• A musty or mildewy odor in rooms that didn’t have one before the storm is worth taking seriously — water can travel inside wall cavities for some distance before it becomes visible at the surface.

If You Find Damage

Discovering storm damage on your property is stressful, but acting in the right sequence protects both your home and your insurance claim.

Document everything before any repairs begin. Photograph and video your property thoroughly — the roofline from ground level (use a zoom lens), all exterior elevations, damaged trees or limbs, gutter condition, and any interior water intrusion or staining. Date-stamp your images. Thorough pre-repair documentation is essential when reporting to your insurance carrier, and it strengthens your claim record.

Take reasonable steps to prevent further damage. If there is an exposed opening in your roof or exterior, temporary protection — such as a properly secured heavy-duty tarp — can prevent water from entering and causing secondary damage. Emergency mitigation of this kind is typically a covered expense under standard homeowners insurance policies. Do not attempt work on your roof or near hazardous trees in unsafe conditions.

Contact your insurance carrier promptly. Call your homeowners insurance company to report the damage and open a claim. Have your policy number and documentation ready. Your insurer will assign an adjuster to inspect the property and assess covered losses.

Work with a licensed restoration contractor. A licensed restoration contractor can document the full scope of damage with a detailed written estimate and can meet with your insurance adjuster on-site to walk through the findings together.
