Catastrophic flooding has triggered a state of emergency across parts of Missouri after what forecasters described as a 'once-in-a-millennium' rainfall sent rivers surging to historic levels.
Thousands have been placed under a flash flood emergency by the National Weather Service with crews having already carried out more than 90 water rescues, according to the Reynolds County sheriff's office.
Relentless thunderstorms dumped between six and 12 inches of rain near the Black River in southeastern Missouri, inundating roads, campgrounds and communities.
Officials warned the danger was far from over on Friday evening, with rivers continuing to rise and additional flooding expected in the coming hours. The river rose to an all-time high of 28.7 feet during the day on Friday.
At least one young woman is still missing after her home was washed away in the flood waters.

Her sister, Kayla Dawn, posted a desperate plea for help on Facebook saying: 'We don’t know a lot right now but what we do know is we need everyone looking for Faith. Her and her home were washed away in the storm this early morning.

In another dramatic scene, around 20 people had to be pulled to safety after a building at the Bearcat Getaway campground near the Black River collapsed beneath them, sending campers into the raging waters.
Missouri State Highway Patrol Sgt Eddie Young said the group had climbed onto the structure before it gave way, forcing emergency responders to rescue them from the flood.
The extreme weather also endangered first responders. During one rescue mission, a Missouri State Highway Patrol boat became entangled in a submerged line.
The two troopers aboard were forced to abandon the vessel and enter the floodwaters before both safely made it ashore without injury.
The floods came after several inches of rain fell overnight on Thursday and into the morning across a long swath of central and eastern Missouri.
The National Weather Service issued flash flood warnings as thunderstorms piled on the area one after another, explained Matt Beitscher, a lead meteorologist with the NWS office in St. Louis.
'It's very, very popular place for recreation,' said Beitscher of the affected counties.
'So there are campgrounds there. There are float trip locations there. A lot of vulnerable populations that would be susceptible to flash flooding.'

Governor Mike Kehoe declared a state of emergency as the crisis escalated, activating one of Missouri's urban search-and-rescue teams while National Guard helicopters were dispatched to reach residents cut off by floodwaters.
'With additional heavy rain expected through the weekend, the threat is not over. If you're camping, floating, or spending time near rivers and streams, move to higher ground and stay alert of weather conditions,' Governor Kehoe stressed.
'Missourians should continue to monitor local forecasts and follow the guidance of local authorities.'
Kehoe also issued a public service announcement as he urged all Missourians to pay attention to the weather forecast and heed warnings, particularly those on or near rivers and streams.
He said that people should have multiple ways to receive alerts, including overnight, as weather conditions change rapidly.
'Never attempt to drive through floodwaters, even if the water appears shallow. Just six inches of floodwater can sweep a person off their feet, and as little as one foot of water can move most cars off the road,' he said.
'More than half of flood deaths in Missouri are victims in vehicles. Nighttime severe weather is particularly dangerous because visibility is severely reduced. If you find yourself stranded by floodwaters, immediately call for help and seek higher ground.'
The two troopers on board were forced to abandon their boat, but fortunately, both made it to safety and were not injured

According to the post, Chris then worked from the emergency command center alongside rescue officials, using detailed maps of the campground to direct first responders to trapped guests. The final rescue was completed at around 11:30am.
Photos showed buildings partially submerged, floodwaters swallowing vehicles and flagpoles, and stunned families surveying the devastation from higher ground, the campground said the destruction could be repaired.
'Campers, vehicles, buses, buildings, and equipment can all be repaired or replaced. Lives cannot,' the post read. 'Our hearts are full of gratitude that every guest was safely evacuated.'
The owners added that while the damage was extensive, they were 'blessed beyond words' that everyone escaped safely.
