Storm Data Entry

Mayes County:

This is the first of three segments of this tornado. The tornado developed on the leading edge of a short convective line of thunderstorms that wasn’t undercut by cold outflow. It moved northeast uprooting and snapping a number of large trees within this segment in Mayes County and then moved into the extreme northwestern corner of Cherokee County. Based on the tree damage, maximum estimated wind in this segment of the tornado was about 105 mph.

Cherokee County:

This is the second of three segments of this tornado. The tornado tracked northeast across the extreme northwestern corner of Cherokee County, uprooting and snapping numerous trees. Based on the tree damage, maximum estimated wind in this segment of the tornado was about 105 mph. The tornado continued northeastward into Mayes County.

Mayes County:

This is the third of three segments of this tornado. As the tornado crossed back into Mayes County, it destroyed a double wide mobile home and damaged a single wide mobile home just north of the E590 Road. A woman was killed in the double wide mobile home and two people were injured in the other mobile home. Trees were uprooted and snapped and debris from the double wide mobile home was transported several hundred yards downstream. The tornado damaged another mobile home south of the E580 Road where it destroyed a greenhouse. Numerous trees were uprooted and snapped along the path until the tornado dissipated just south of the E570 Road. Based on this damage, maximum estimated wind in this segment of the tornado was about 125 mph.

August is one of the least active months for tornadoes in this part of the country so the intensity of this tornado was even more unusual. In fact, this is only the 4th strong tornado (EF-2 or EF-3) that has been confirmed in eastern Oklahoma since 1950.
