The National Weather Service office in Paducah says its damage survey determined an EF-1 tornado hit Moors Marina along Kentucky Lake in Marshall County on Sunday.
The most extensive corridors of wind damage Sunday appeared to extend across far western Kentucky.
This comes on the heels of Friday's storms. Widespread wind damage was reported across the region with heavy rain that produced some flash flooding. The vast majority of the damage was due to straight-line winds.
Winds in some locations were clocked around 70 mph, including a 72 mph wind gust at the Cape Girardeau airport.
Two fatalities were blamed on the wind. One fatality occurred on the Current River in Carter County, Missouri. A second fatality occurred in Pulaski County, Illinois. Both fatalities were due to trees falling on victims. There were also at least three serious injuries in the same counties due to falling trees.
The persistent rain showers in the region are forcing officials in Jackson County to step up their flood fighting efforts.
The county's emergency management agency says two more 10-inch pumps were delivered to the Big Muddy Levee Pump Project to help reduce the amount of internal water from heavy rains. All other pumps are running in the County and the Mississippi and Big Muddy Rivers are forecast to take rise slightly.
