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

The tornado developed near the intersection of 114th Ave and N 16th Street where a power pole was pushed over. The developing tornado crossed Schnable Lake and heavily damaged the campground on the north side of the lake, including several flipped trailers and destroyed roofs from falling trees. Damage to structures

continued as the tornado crossed 115th Avenue. The most significant damage occurred near and east of the intersection of 116th Ave and US-131 and continued east into downtown Martin. The tornado slowly weakened as it moved east of Martin before

dissipating near the Allegan/Barry county line (Boysen Road).
