The path drawn at its surveyed width of 75 yards (0.04 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

A storm damage survey confirmed that a tornado developed south of Waterford. A private property sustained widespread and severe tree damage with several hundred

mixed hardwood and softwood trees uprooted and/or snapped on this

20 acre property. Another concentrated area of significant tree damage

was noted between Forrester Rd and Tiffany Dr. Many homes and outbuildings

sustained minor to moderate damage from tree fall along this track. This

tornado continued east but quickly weakened and ended west of Johnson Rd

as a larger scale microburst overtook the tornado.

The wider storm

A decaying derecho moved through the area late in the evening on July 15th. Storms raced eastward into southwest Lower Michigan and northern Indiana, prompting several Severe Thunderstorm Warnings for winds up to 70+ mph and Tornado Warnings for embedded rotation along the line. Three tornadoes were confirmed.

Began near Waterford (41.6426, -86.8714).
