The path drawn at its surveyed width of 150 yards (0.09 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 was the fourth of five tornadoes spawned by the same supercell thunderstorm. Roofs of residences and outbuildings were damaged. Numerous trees were blown down.

The wider storm

Moisture from the Gulf of Mexico surged into Arkansas at the end of April, so conditions in the state became warm and humid. On the 30th, a strong area of low pressure aloft approached from the west, resulting in the development of thunderstorms. Wind shear, a change in wind direction and speed with height, was present. This created a favorable environment for the formation of tornadoes.

Began near Kensett (35.2105, -91.6726).
