What EF2 means. On the Enhanced Fujita scale, EF2 is considerable damage: roofs torn off well-built houses, mobile homes destroyed, large trees snapped or uprooted, consistent with estimated gusts of 111–135 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 the continued path of the tornado that crossed from Wabaunsee County into Osage County and weakened. The tornado path narrowed and damaged hedge row trees and two structures before dissipating.

The wider storm

On the evening of Tuesday, February 28 2012, a very strong upper level storm system caused widespread thunderstorms to form across most of central and eastern Kansas. The storms initiated approximately 4:00 PM and increased in coverage and intensity throughout the night. Since atmospheric instability was not extremely high there were few reports of severe hail; however, many structures across the area were damaged due to strong, straight-line thunderstorm winds.

The most significant event from the evening of February 28 was a strong tornado that impacted Harveyville, Kansas at approximately 9:03 pm CST. The town sustained significant damage to some structures, including an apartment complex and a church. On Wednesday, February 29 a National Weather Service survey crew traveled to Harveyville to assess the damage. The tornado caused at least 12 injuries and one fatality. The survey crew gave a preliminary assessment of EF-2 damage, indicating wind speeds of 111 - 135 mph.

Three other tornadoes occurred across the area that night, but no injuries and only marginal damage to outbuildings and structures occurred from these other tornadoes.

Began near Burlingame (38.7948, -95.9477).
