The path drawn at its surveyed width of 400 yards (0.23 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

This is a continuation from a tornado that moved southeast from Wayne county into Pike county. The tornado moved past Wolf Lake, Teedyuskung Lake, and Fawn Lake still doing EF1 damage to trees. The path begins to narrow and oscillate between EF0 with little damage, to EF1 with trees snapped and uprooted. It crosses Route 590 (twice) and the Lackawaxen River east of Rowland and appears to dissipate over State Game Lands about 2 miles northeast of Greeley.

The wider storm

A warm front lifted north into northeast Pennsylvania during the afternoon, putting the area into the warm and moist air mass of the warm sector, with temperatures in the mid 80s and dew points in the 70s. Showers and thunderstorms developed in the vicinity of the front in this unstable air mass. Stronger storms developed across southeast Susquehanna county, with one storm in particular developing strong rotation as it moved southeast into Wayne county. This storm went on to produce four tornadoes and other significant microburst damage as it continued southeast through Wayne and into Pike county.

Began near Mast Hope (41.5369, -75.1211).
