EF1 tornado, Monroe and Wayne counties, New York, September 2, 2026

This EF1 tornado ran 3.2 miles across Monroe and Wayne counties on September 2, 2026, touching down at 7:30 PM EDT and reaching 130 yards wide. It killed nobody.

Preliminary. This is NWS BUF's damage survey, filed in the Damage Assessment Toolkit as Webster & Ontario. The rating, the path and the casualties are the survey's and can change while it is revised. The Storm Prediction Center compiles the official record of 2026 from these surveys and publishes it in the spring of 2027; this page moves to that tornado's permanent address when it does.

The rating scale

Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

  1. EF065 to 85 mph

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. EF186 to 110 mphthis tornado

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. EF2111 to 135 mph

    Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.

  4. EF3136 to 165 mph

    Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

  5. EF4166 to 200 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. EF5over 200 mph

    Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

  7. Unrated

    The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

What the survey found

The National Weather Service in Buffalo completed a damage survey across eastern Monroe County and western Wayne County today in response to reports of concentrated areas of damage near Webster and Ontario from a line of severe thunderstorms on Wednesday, September 2nd.

Embedded low level rotation within a squall line moved through Webster shortly before 7:30 pm, and a tornado touched down in the vicinity of Salt Road just north of Route 104 as evidenced by several snapped softwood trees. The tornado then crossed Route 104 as it headed southeastward, with another area of concentrated damage noted near the intersection of Basket Road and Ridge Road. Here several hardwood trees were snapped or uprooted, and a fewl power poles were knocked down. The tornado then continued to the southeast through open fields until encountering a small subdivision just west of County Line Road. Here the most significant damage occurred with roof uplift, considerable shingle loss, and siding damage on a few homes on Halesworth Lane and Bannerwood Drive. Numerous trees in the subdivision were also snapped or uprooted. Additional tree damage was seen along Foxworth Drive, and then the tornado travelled through a large forested area with no road access. Finally, the tornado emerged along North Lincoln Road just north of Whitney Drive, and produced extensive tree damage at a large property where numerous mature trees were uprooted or snapped, before lifting just east of this area.

The damage survey

16 damage points were recorded along this path by NWS BUF, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 105 mph.

  • Four large hardwood trees uprooted at a cemetery along Ridge Rd
  • Several large softwoods uprooted and snapped
  • Extensive tree damage on two properties on the north side of Ridge Rd. Numerous trees snapped and uprooted, numerous large limbs down.
  • Softwood tree snapped at the trunk just west of Salt Rd

Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The forecast that day

The Storm Prediction Center had this point in a Enhanced Risk, with a 0.05 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 20:00 UTC.

What this means

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. A survey can be revised, so the rating, the path and the casualties can all still change.
