The video below is from a security camera at Moors Resort and Marina in Kentucky (southeast of Paducah) on June 23, 2019. These people should have been paying closer attention to the weather if they are going to be out on the water. There is no safe place on the water during severe weather. If you have plans to be out on the water this summer make sure you check the weather conditions on a regular basis. This was way too close for those people to be on the boat/dock with a severe storm.
The National Weather Service in Paducah, KY went and surveyed the damage and rated the tornado an EF-1 based on the damage.The image below is part of the survey summary.
The map below shows the path (green line) of the tornado (0.1 miles).
The map below shows the storm reports and I put a red box where the above video is from.
