The path drawn at its surveyed width of 90 yards (0.05 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

The National Weather Service in conjunction with WxorNot Bowling Green Meteorologist Landon Hampton determined a low end EF-1 tornado touched down in southwestern Butler County. The tornado touched down south of D&G archery in far western Butler County. The overwhelming majority of the damage was snapped, twisted & uprooted trees. The only exception was a building damaged right near the initial point where it touched down near a pond. The tornado was in an extremely rugged area except where it crossed Hwy 70. The tornado ended about 3/4 mile northeast of Hwy 70 in rugged countryside.

The wider storm

The combination of a moist and unseasonably warm air mass and an approaching low pressure system and cold front brought multiple rounds of severe weather to central Kentucky during the early morning hours on March 1. In the end, there were 4 tornadoes across central Kentucky. In addition to the tornadoes, there were several areas of intense straight-line winds estimated up to 100 mph in places. The impacts included numerous areas of structural damage and downed trees. The widespread rain also brought several rivers into minor flood.

Began near Pleasant Hill (37.1840, -86.8800).
