Three people are dead after severe storms swept through Texas, leaving behind flooded and clogged roads. 

Between 6 to 12 inches of rain fell in parts of the south of the state in the past 24 hours, according to the National Weather Service. 

Flash flood emergencies had to be issued on Thursday night and into Friday morning in counties along the US-Mexico border. 

News footage from the flooded communities captured the devastation, with waterlogged cars abandoned on streets.

In an update on Friday evening, officials in Hidalgo County said that three people had died. Their identities remain unknown at this time. 

Officials in Harlingen county said they received over 21 inches of rain in the last week alone, with the rainfall on Thursday causing 200 residents to be rescued. 

In Alamo, the police and fire department responded to more than 100 water rescues, including people stranded in their vehicles and trapped in their homes.

Fire officials in the county confirmed there were over 100 high water rescues in the area after a foot of rain fell on Wednesday. 

In some counties rainfall totals exceeded records that go back over 100 years. 

The rains stopped on Friday morning before moving towards Louisiana and eastern parts of the state.  

The aftermath persisted, with more than 3,400 homes in several counties remained without power on Friday afternoon. 

A flood warning was still in effect for portions of South Texas, including Cameron, Hidalgo and Willacy counties, through early Friday afternoon, according to the National Weather Service.

The National Weather Service said: ‘There´s a break from the rain this morning, which will allow flood waters to gradually recede, but we´ll still need to keep an eye on the development of isolated showers and thunderstorms once again this afternoon.

‘Any additional rainfall will be quick to cause flooding issues given the heavy rainfall that has already fallen.’

Alamo Fire Department Chief R.C. Flores told reporters: ‘I assure the public that we are assessing the situation on the hour, every hour. We´re constantly going out, not just in our city.

‘Just because the storm is over, it doesn´t mean that the emergencies and the disaster is over. We are going to continue to work as long as we need to.’ 

Weslaco Mayor Adrian Gonzalez said his city was inundated with about 14 inches  of rain, prompting 30 to 40 water rescues of stranded motorists and residents trapped in their homes by rising floodwaters.

‘It’s a historic rainstorm and it´s affecting all the Valley, not just Weslaco. It´s just so much water in a short period of time,’ Gonzalez told reporters.

In neighboring Cameron County, officials asked Gov. Greg Abbott to declare a disaster for the county after more than 17 inches of rain caused significant flooding.

‘The rainfall amounts we received have been record-setting, and not in a good way. All county resources are being utilized right now, and we are assisting in all ways possible,’ Cameron County Judge Eddie Treviño Jr., the county’s top elected official, said .

Valley International Airport in Harlingen was closed on Friday and all flights were canceled due to area flooding.

‘We are working tirelessly to reopen and focused on ensuring safety,’ airport officials said in a statement.

Some schools and college campuses canceled classes on Friday also due to the weather.

A shelter had to be opened in Weslaco and officials in Harlingen had opened the city’s convention center as a shelter for those in need.
