Record-breaking rains across Texas and Oklahoma caused widespread flooding over the weekend, sweeping away hundreds of homes and killing at least three people.

The riverbeds where the flash floods took place were normally dry, so people were caught unaware and their homes were destroyed. At least 2,000 residents were left with no choice but to flee their homes, according to Fox News.

A day after the flash floods, the skies are showing some calm, but that does not mean there is no longer any threat to the region, according to CNN.

The waters from the torrential downpour is reportedly too much for rivers and creeks to contain. Early Monday, runoff still peaked; thus, threats of further floods still continue, warned the National Weather Service.

Of the three people killed, two were reported to have been from Oklahoma. One of the two is a firefighter who was swept away by the current as he was rescuing people from high waters. The other was a woman from Tulsa who crashed while on the road.

One other person who died from the harrowing floods is a man from Texas, whose body was found along a flooded area in Blanco River. The river surprisingly rose to 26 feet in only an hour, according to authorities.

Meanwhile, in Wimberley, Texas, eight people remain missing. Three of them are children, according to KXAN.

Emergency Management Coordinator Kharley Smith in Hays County, Texas, said that crews are continuing surveillance of the damage brought on by the floods. He added that around 350 to 400 homes in Texas were swept away, while more than 1,000 were damaged.

The extent of the damage remain unknown, authorities said, adding that they are bracing for more rainfall that could bring more floods into the city.

According to weather forecasts, there are new thunderstorms to arrive Monday, which could bring more heavy rains. Forecasters warn that with the ground already drenched, even small amounts of rain could bring forth unwanted results.

"Only an inch or two of rainfall could quickly lead to more flash flooding concerns," according to a National Weather Service advisory Sunday.

Meanwhile, in western Oklahoma and certain parts of Texas, particularly in the Panhandle and central areas, there is still moderate drought and unusually dry conditions, according to the U.S. Drought Monitor. The torrential waters from the recent rainfall are expected to put a dent, however, reported CNN. Below, residents share their situation on Twitter.
