Asked on Fox News's Fox & Friends today whether there was any specific breakdown in this case, Noem says: "Not that we found so far."
“The National Weather Service put out the alerts when they received them and, unfortunately, in many places in our country we have flash floods like this that do occur, and the notification was proactive and out there", she says.
“Would everybody like more time? Absolutely. So many situations when we see terrible events like this and these natural weather disasters, more notification is always extremely helpful.”
Noem adds that the National Weather Service under US President Donald Trump "has been working to put in new technology and a new system because it has been neglected for years".
“It’s an ancient system that needed to be upgraded and so President Trump recognised that right away and got to work on it when he came into office in January but that installation is not complete and that technology isn’t fully installed."
More than 80 people have been confirmed dead across central Texas following Friday's flash flooding.
The worst hit area is Kerr County, with 68 fatalities confirmed, including 28 children, the BBC's US partner, CBS News, reports.
The county is home to Camp Mystic, a girls' summer camp on the banks of the Guadalupe River, which has said it is "grieving the loss of 27 campers and counsellors".
Elsewhere across central Texas, there have been six confirmed casualties in Travis County, which is home to state capital Austin, three casualties have been confirmed in Burnet, two in both Kendall and Williamson, and one Tom Green County, according to CBS.
As we often see in times of hardship and tragedy, people come together to help where they can.
In Texas, many volunteers are handing out food, clean water and donated clothes to those who need it.
Many have also volunteered - in trucks and on horseback - in the search for survivors and victims.

Several factors came together to create the devastating outcome we saw in Texas last week.
First there was the weather patterns at the time.
The remnants of an ex-tropical storm had become embedded within a broader area of very unstable air within the region. Unstable air is air which has the ability to rise rapidly to form large storm clouds.
Tropical Storm Barry, that caused flooding across the Yucatan Peninsula in Mexico a week earlier, had tracked across the Gulf of Mexico to decay over north-east Mexico. This had meant there was already large supply of moisture in the atmosphere.
Wind patterns across the region at the time also resulted in a flow of humid, moisture-laden air from Gulf too.
The next factor was the geography and topography of the area: Kerr County, where the worst of the floods occurred, is a hillier area which forced moisture-laden air upwards helping to build huge storm clouds.
The ones that formed over the area were so large they effectively became their own weather system, producing huge amounts of rain over a larger area.
It was slow-moving, adding to the rain totals and creating further thunderstorms along a zone that continued to affect the area containing the Guadalupe River.
More than 80 people have been confirmed dead and dozens are missing following flash floods in central Texas on Friday.
The video below shows how the water level of the Llano River in Kingsland, Texas rapidly increased.
Image source, ReutersWith the death toll in Texas exceeding 80 people, questions are being raised about whether adequate flood warnings were provided and why people weren't evacuated ahead of the deluge.
In the space of 45 minutes in the early hours of Friday morning, the Guadalupe River rose by 26ft (8m), causing it to burst its banks.
By then there had been several flood warnings issued, including from the Texas Division of Emergency Management (TDEM) and the National Weather Service (NWS).
The NWS has said it was heartbroken at the loss following the floods, but that it did all it could, conducting briefings on Thursday and issuing a flood watch warning that afternoon.
People have reported receiving text message alerts on their mobile phones early on Friday morning, warning them of flooding. Some residents told the New York Times, external they did not understand the seriousness of them and others said they never received any at all.
Before the tragedy, there had also been concerns over the Trump administration's budget cuts to the National Oceanic and Atmospheric Administration (NOAA) - the government agency that operates the NWS.

We're starting to hear more stories of heroic rescues emerging from Texas.
Homeland Security said on X that Scott Ruskan, a Coast Guard rescue swimmer, was directly responsible for saving 165 lives.
"He is an American hero whose selfless courage embodies the spirit and mission of the Coast Guard," the government department said.
Meanwhile, Louisiana governor Jeff Landry drew attention to camp counsellor Emma Foltz, who is from his state.
She played an "instrumental role" in evacuating 14 of her campers to safety, he posted on X.

Speaking to BBC 5 Live, Washington Post reporter Arelis Hernandez says rescuers are searching a "tremendously large area" facing "matted" debris, like tree limbs and various things that were sucked out of homes, cars, "just all piled up on each other with river silt".
"You have to go foot-by-foot and untangle all of this in case there’s something or someone underneath it all," he says.
He adds that a group of rescuers he was with had already found "three bodies and the more they look, the more they’re finding".
Ordinarily, he says, "this is a beautiful place, an idyllic place", but "seeing so many of these young girls lost, losing their lives and missing has absolutely ripped this place apart".

A flood watch has been issued covering Kerr County – and surrounding areas of Texas - throughout Monday.
Further downpours and thunderstorms are expected to develop with the National Weather Service warning that some places could see 2 to 4 inches (51-102mm) of rain.
Up to 10 inches (254mm) could fall very locally which could hamper rescue efforts and cause further flash flooding, especially with river levels already so high.
However, it is impossible to pinpoint exactly where the wettest places will be, and this is always the problem with predicting summer thunderstorms.
Forecasters can see that the right ingredients are there - a supply of moisture and instability in the atmosphere - but even the most sophisticated computer models will struggle to identify exactly where those ingredients will come together to produce the most damaging downpours.
Rescue volunteer Greg Froelick is heading up rescue efforts to locate survivors near Camp Mystic - and tells the BBC he's heard of people being found up to "eight miles (12.8km) down the river from where the camp was".
Describing the damage down there, he says "it's pretty crazy" - with "giant trees wrapped around another tree, debris piles 20ft-plus high... it's a complete disaster to be honest".
In an interview with BBC News on Sunday evening, he says he has seen "clothing and items from the camp dressers scattered everywhere, up and down the river".
Rescuers have been searching with dogs, clearing brush and are now planning to use boats, he explains.
"It rained on us most of the day today," he says, and adds they had to seek higher ground when a "15ft wall of water" began surging through the area.
Image source, ReutersA major focus of the search has been Camp Mystic, a Christian summer camp for girls perched on the banks of the Guadalupe River which suffered significant damage.
A number of the children were killed and several are thought to be missing following the flash floods.
The camp in Kerr County said it was "grieving the loss of 27" campers and counsellors in a statement posted today.
Its longtime director Richard "Dick" Eastland has been reported as among the dead.
