A severe flash flood in Kentucky has left multiple fatalities, with at least three confirmed dead and more feared as rescue operations continue.

Authorities confirm four deaths in Kentucky from flash floods caused by thunderstorms delivering heavy rainfall, with some areas receiving up to seven inches.

Bullitt County issued evacuation notices for Lebanon Junction following a moderate dam embankment failure, while warning that floodwaters may recede in spots but danger remains.

Storms brought six to seven inches of rain in certain areas, with rain easing later but ongoing concerns about waterlogged roads, downed trees, and debris; several counties remain under flood watches.

Five counties declared local states of emergency as five search-and-rescue teams and high-axle vehicles were deployed and an emergency shelter opened for flood victims.

Officials warn that flash floods can develop quickly anywhere and tie the event to broader climate-change-related increases in severe flooding in some regions.

The report places current flooding in the context of prior catastrophic floods in Texas as a reference point for ongoing flood risk.

National Weather Service data indicates roughly 3 inches of rain fell in the area over the past two days.

Governor Beshear declared a state of emergency and urged residents not to drive after dark as conditions remain dangerous and heavy rainfall is expected to continue into the evening.

The governor also noted ongoing heavy rainfall with forecasts through the night and reinforced cautions to avoid nighttime driving due to low visibility.

A National Weather Service flash flood warning covered parts of Kentucky and Indiana, with Indiana towns reporting 4 to 10 inches of rain and more expected.

Three of the fatalities are in Madison County and one in Jackson County, according to Governor Beshear, with identities and details not yet released.
