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

An EF-1 tornado continued into Anoka County from the Camden Bridge along the Mississippi River, north-northeast to the east side of Fridley, to Spring Lake where it moved into Ramsey County.

Damage was extensive along the path where it moved into a rail yard and a large industrial facility. A large metal building roof was ripped off in the industrial area, and eight train cars were tipped over where EF-1 damage was observed. Several warehouses sustained damaged along Miami Street where a roof was blown off.

The tornado then moved across residential sections of Fridley, before it weakened as it continued northeast across the east side of Fridley, near Spring Lake. Damage was confined to trees blown down along the path, then moved into Ramsey County.
