NWS Tornado Damage Surveys for June 6, 2018

National Weather Service survey teams mapped 2 tornado paths from this storm day (1 EF3, 1 EF2), 12 miles in all. The map above draws each surveyed path as the NWS mapped it, colored by the EF rating of each stretch, in place of the straight start-to-end line.

Rating	Peak wind	Path length	Max width	Deaths / injuries	On the ground	Surveyed by
EF3	150 mph	11.3 mi	600 yd	0 / 0	23:43–00:36 UTC	NWS Cheyenne
EF2	120 mph	0.8 mi	–	0 / 0	23:49–00:05 UTC	NWS Cheyenne
