Survey crews are working to determine how many tornadoes touched down, estimate peak wind speeds, assign official ratings using the Enhanced Fujita scale and map each tornado's path.
Teams from the National Weather Service office in Wilmington, Ohio, are surveying damage in Gallatin, Owen and Grant counties, where residents reported seeing a large tornado carrying debris Tuesday afternoon, particularly near Owen County and Sparta.
The National Weather Service office in Louisville previously confirmed a "large and extremely dangerous" tornado struck Munfordville in Hart County, leaving behind significant structural damage and widespread power outages.
Survey teams have also confirmed a brief EF-0 tornado in Grayson County with estimated peak winds of 85 mph. In Fairdale, located in Jefferson County, meteorologists confirmed at least EF-1 damage with estimated winds of up to 90 mph.
Additional damage surveys are planned in Meade, Harrison and surrounding counties as meteorologists compare radar data with reports from the ground to determine whether additional tornadoes touched down.
The storms left thousands of customers without electricity and caused scattered damage along major transportation corridors, including U.S. Highway 60.
Emergency management officials are urging residents to stay clear of downed power lines, avoid damaged areas when possible and leave roads open for emergency responders. The National Weather Service expects to release additional survey findings over the next 24 to 48 hours as assessments continue.
