The Noah's Alert Ecosystem
Our patented three-tiered framework ensures continuous monitoring, physical deployment, and seamless signal amplification across rugged terrains.
The Mobile Responder
The Sentinel is an autonomous emergency broadcast device deployed directly into the surging river channel to travel ahead of the floodwaters.

Noah's Alert redefines flash flood emergency response. By combining real-time sensing with autonomous deployment of mobile alert devices, it delivers loud, unmistakable warnings directly to people in the path of a flood—especially where traditional infrastructure can't reach. The result is faster awareness, faster action, and lives saved.
The Threat: Surviving the Silence
Survivors of devastating river channel disasters recall one terrifying reality: the total absence of a warning. You cannot hear a flash flood rising over the sound of localized rainfall, and when the surging torrent finally breaches the banks, it strikes with an unstoppable, catastrophic force.

An authentic, first-hand look into the reality of flash flood disasters and the deadly cost of communication silence.
How many times have you camped on that section of the Guadelupe River before?
I grew up camping on the Frio River at Leakey but had never stayed at this section of the Guadelupe before.
Did you ever think that the river might come up that high and pose such a threat?
No. It was raining before we went to sleep around 10:00 p.m. but the water level was unchanged.
Did that park have any kind of alert/siren system that you know of?
Not that I'm aware of. If they had an alert system, it was not used. To be clear - I don't blame anyone else for this. I'm a firm believer in personal responsibility (especially when it comes to the safety of your family). I still carry a lot of guilt for letting my family get that close to death and not having the foresight to know this could happen.
How quiet was everything at that time?
Very quiet. The only sound I remember when we were evacuating was the sound of the rushing water, trees cracking, and vehicles/RVs being pushed around like toys.
Could you hear the river as it was rising?
No.
What time did the truck honk it's horn?
Around 4:30 a.m. if my memory is correct. We were able to find out who was honking their horn, and I've kept in contact with him and am forever grateful to him.
How long did it take for you to get everyone to safety after you heard your wife's screams?
3-5 minutes at most. I moved our van to high ground while she woke our boys, one of whom was in the loft upstairs. The water was already pushing campers and trucks down the river at that time. Water got into the floorboard of our van when I moved it to the top of the hill.
I ran back down to the cabin, and the water level had already risen noticeably. I saw other people standing on the front porches of their cabins in shock. When I got back to our cabin my wife and sons were waiting for me on the porch. I put my youngest son (6) on my shoulders and my oldest (8) in my arms. My wife carried our dog. We waded through the water and had to dodge cars/trailers that were being swept down the river. The water was up to my waist at that time and rising about 1' per minute. Providence alone saved us.
If we had been further into the campgrounds (away from the only entrance/exit) or if my wife hadn't been woken up when she was or if we had gotten struck by floating debris or fell down - we wouldn't have made it out.
Where did you go?
At first, we just sat in the van at the top of the hill in front of the office. My wife was in shock and very upset about all the people that were still trapped in the campgrounds. There were fire trucks and rescue personnel on the scene by that time, but I don't recall ever hearing any sirens. Only saw the flashing lights. Then I drove to the highest place that was nearby so I could come up with a plan. We didn't know if the river was going to keep rising and if we would be trapped in town or get caught in it trying to get out but we decided to get to 1-10 as quickly as possible. Drove straight home and got there safely.
Do you know if others did not make it out in time?
I knew then that people did not survive. I saw campers floating down the river with people trapped inside. According to some reports - 37 people were killed in our campsite alone.
Would have some type of siren/broadcast system helped in that situation?
I have no doubt that any type of siren or warning system would have saved lives. People were in total shock by what was happening and the speed in which it was happening.
