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 brief EF1 tornado occurred during the evening of April 9th in Kosciusko. The tornado began at the intersection of MS Highway 12 and North Jackson St where an awning and portion of a sign was blown off the CVS Pharmacy. The tornado quickly reached peak intensity as it moved southeast where several trees were uprooted along Knox Rd, including one that fell onto an apartment building. The tornado continued southeast crossing Lucas St and Fairground St where the most concentrated path of damage occurred. Here, multiple trees were uprooted along with several pine trees that were snapped. Several homes also sustained roof damage due to falling trees and branches, and one home on Lucas St had a portion of its roof and interior ceiling blown in after a gable failed. The tornado began to weaken as it crossed East Adams St and East Jefferson St where mainly large tree branches were snapped. Two trees were also uprooted in this area. The tornado quickly dissipated after crossing East Jefferson St and was on the ground for approximately one minute. Estimated peak wind was 95 mph.
