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 tornado downed trees and power lines before tracking into an industrial park at the Port of Little Rock, where the worst damage occurred. A number of power poles were knocked down, one industrial building had damage to its walls, and another industrial building suffered roof damage.

The wider storm

A cold front and strong area of low pressure aloft approached Arkansas on the 14th. The result was an outbreak of severe weather from the evening of the 14th through the pre-dawn hours of the 15th. Several tornadoes occurred. Additionally, storms developed into line segments which often bowed out, creating damaging thunderstorm winds.

Began near Ward (34.6586, -92.2941).
