Tornado - 3.1 Miles WSW Beaver Dam, KY
Ohio County

Date	June 25th, 2018
Time (Local)	1050 AM CDT
EF Rating	EF-1
Est. Peak Winds	95-100 MPH
Path Length	0.6 Miles
Max Width	100 Yards
Injuries/Deaths	N/A
Summary: This brief tornado did most of its damage at treetop level, snapping the trunks of or uprooting at least two dozen large, mature oaks and cedars, and causing limb damage to many others. In one case, it snapped the 2-foot diameter trunk of a large cedar less than 5 feet above the ground, but lofted the tree over nearby utility lines - which remained intact - and deposited the tree 200 feet to the east. The tornado did occasionally reach closer to the ground, causing significant damage to two structures. The first was a large brick ranch home, which had most of the north half of its roof torn off, and insulation spread eastward in a narrow path. One piece of roofing lumber was found 500 feet ENE of the home. A second building, a large 2-story brick industrial building 1/2 mile east - had about 20 percent of its metal roof peeled off. Immediately after hitting this building and downing trees in a nearby cemetery, it crossed U.S. Hwy 62 and did additional tree damage for another several hundred feet as it moved through a wooded area. The National Weather Service thanks Ohio County Emergency Management for their assistance in this survey, including drone surveillance that helped identify the path of this storm.

Tornado - 2.3 NE of Bee Springs, KY
Edmonson County

Date	June 25th, 2018
Time (Local)	104 PM EDT
EF Rating	EF-0
Est. Peak Winds	80-85 MPH
Path Length	1.6 Miles
Max Width	50 Yards
Injuries/Deaths	N/A
Summary: This weak tornado skipped along mainly at treetop level near the Moutardier Recreation Area about 1/2 mile south of the Edmonson- Grayson County Line. The tornado snapped the upper reaches of several tree trunks near its initial point near severalhomes - leaving debris in a circular pattern - then skipped eastward, causing other minor tree damage before dropping down to become a waterspout on Nolin Lake northeast of the Moutardier Marina. The waterspout was captured on video and shared on social media, confirming the existence of the rotation and funnel. The waterspout dissipated as it approached the east shore of the channel.
