Its Tuesday September 1, "The Anatomy of another wall of water" We start here. Three days after that apocalyptic flood in Nepal, horror hit an American canyon. Way too much rain too quickly to handle over this area. The science behind the Grand Canyon disaster. Six months of war with Iran going from hot to cold. Right now, it's an economic fight. It's an economic fight for survival for the Iranians and for the U.S. Why some experts say we could be closing in on a new normal. And 29 military service members trying to save their careers. His argument was effectively they're lying about their gender and therefore are serving dishonorably. The latest in the legal battle over President Trump's ban on trans troops. From ABC News, this is Start Here. I'm Devon Dwyer. Hey, Brad's out today, but I've got you covered from DC. In these waning days of summer, we're used to hearing about the threat of flash floods from waves of thunderstorms rolling in. But what happens Saturday afternoon in the Grand Canyon in Arizona is as rare as it is horrifying. We just heard people yell "Run, run, run!" and there's 40 of us running through this deep muddy water. One of the seven natural wonders of the world and one of America's most popular national parks. The Grand Canyon drops a mile deep from the surface down to the Colorado River. And in an instant it became a death trap. The water level in the creek just seemed to be getting bigger and bigger as war water was coming into the creek. This 15-foot wall of water came through the campground in Phantom Ranch and just wiped out all the bridges in the creek. Bridges are gone. Dozens of people had to be airlifted after campgrounds and hiking trails were washed away. And today, more than 60 hours after water's rushed through, there's an urgent search for others missing who may have survived. Authorities already confirmed some did not. "My heart goes out and our heart goes out to them and their families." To better understand how this unfolded and why it happened, the science behind it, I want to bring an ABC meteorologist, Kent and Gwecki. So it was kind of a series, Devon, of rain events that happened. It happened in four rounds of rain. It started at 8.45 in the morning with the first round. Second round was at 10am, third round was at 1pm. And the final round was at 2.30pm. So it all happened within about six hours. Now the first three rounds, they were very light. It was light rain. It helped to saturate the soil, meaning it made the soil kind of completely full of water. Where it can't really take in anymore. And it really got the creeks and the drainage areas rolling. You know, they were already starting to get just a little bit higher. But nothing serious until that fourth round hit. And that was by far the heaviest. They got around an inch of rain within 30 minutes. Also fell, of course, over very steep terrain. It fell over desert landscape and those saturated soils because of the first three rounds. This water was rising when we were running through the trail, which should have no water. We're ankle deep. Halfway down we're knee deep. And importantly here too, it fell over the Dragon Bravo fire, which remember happened about a year ago in July of 2025 when 150,000 acres burned. And there was all these factors, but it was really those four rounds of rain. And especially that last one, that just brought way too much rain too quickly to handle over this area. This is monsoon season down there, right? And so the area is used to heavy rain this time of year. But what made this so different? Yeah, you're right. I mean, flooding and water itself is what formed the Grand Canyon, right? The Colorado River moving through it and all the flooding over the years. What's interesting is of course they've had a lot of floods in the past, but a lot of them were actually before the 1960s, because before then they didn't have a dam or multiple dams to control the river. The bunk houses that the pipeline workers stay in start coming down the river with all their bunk beds, all their barbecues, their ice tests, everything floating down the Colorado River. This flood washed out bridges that had been built. If we had been on the bridge at that time, we would have been knocked into the water and the prospects would not have been good. Pathways that people are traveling on that have been there for many years. And so this is certainly a very rare event, but flooding in general isn't necessarily too uncommon there. It's just that this one was very extreme. Yeah, and I imagine the alneenial conditions, climate change, I understand there was some tropical storm remnants in the area. It kind of sounds like a perfect storm to be honest. Yeah, it kind of starts with the heat dome that's from Texas, Louisiana, and over then to Florida and the Carolinas, and actually what happens around that heat dome is things flow around it in a clockwise fashion. So that's pushing the wind and the moisture from the Gulf and from the Pacific into the desert southwest, helping to amplify the already natural monsoon that's over that area. We have a very strong alneenial happening. And there's also a huge marine heat wave that's happening off the coast of Baha, California, where the ocean temperature is there at the surface. They're 5 to 15 degrees above average. It is really astronomically warm in the ocean, which of course leads to more evaporation, and then more moisture, of course, as well. And then you have more moisture in the atmosphere, but the atmosphere is also warmer because of our human induced climate change. The air temperatures are warmer, of course, as well, than they ever have been. And so because of that, the atmosphere holds more water. The warmer the atmosphere, the more water it holds, which means in theory, then it can also dump more rain as well to get it back out of the atmosphere. So the atmosphere is certainly primed more for this type of flooding. It does seem like something like this is likely to happen again, right? I mean, I guess is there any silver lining in it? Will this help with the drought in Arizona right now? No, it's not going to do much even to lake me, that that's downstream of the Grand Canyon, actually some of the debris from this that washed away into the Colorado River from the Grand Canyon will likely make it to lake me. Boxes and stuff in the river, and there was a fridge we even saw. The scariest thing was there was like a cabin that washed down the river. So actually people who are boating around the lake are going to have to watch out for some of this debris likely. So this probably isn't going to fix the drought there, and there's a huge drought that it's continuing to build over the west, which we knew was going to happen, because it was a record low snowpack, and that's really what feeds the Colorado River. So what's going to make a big difference is a big snowy season. People should understand, is this canyon, it doesn't, you don't decide the canyon, the canyon will make its own mind up. Unfortunately, we're forecasting, of course, one of the warmest, we already had, of course, an extremely warm winter last one, but this next one's likely going to be one of the warmest that we've seen, at least globally, as well, we'll see what it does in America, but we really need the snowpack, that's what fuels the Colorado River. So these kind of floods here and there aren't going to do that. Okay, Kenton, thanks so much for breaking that down for us. Yeah, you're welcome, David.

When President Trump launched a tax on Iran earlier this year, he repeatedly told the American people it would be a swift and brief operation. That was Trump in March, today marks six months and four days of that war. The President posted mission accomplished on social media over the weekend, but some military units sent to the Middle East are already getting orders to extend their deployments into next year. The famed 82nd Airborne Division, which would lead a ground invasion of Iran if it came to that, will be extended up to at least March 2027, according to an internal document we've reviewed at abc. One time, of course, no apparent progress in a deal to curb Iran's nuclear ambitions and the straight of Hormuz that critical pathway for the global oil supply remains the primary military focus. I want to bring an abc. Steve Ganyard, a combat-decorated marine pilot who's held top positions at the Pentagon and State Departments. Steve always great to have you, walk us through the latest. After a month without strikes, we're seeing the U.S. and Iran trading fire again. What is the tip for tat tell you about where we're at? I think it's interesting that it's been so quiet so long. What's then come hit with the U.S. headword, these mobile rocket launchers, and they're fairly small, but the U.S. believes that they were a kind of rocket launcher that could put small sea mines out into the straight. As you know, they don't have to be big mines as long as the insurance companies and as long as the shipping companies believe that their ships could be in danger because there are mines in the water. It doesn't matter how big those mines are, it's still too much of a risk for most of them. These Iranians know that they can create doubt, that they can create confusion by mining the straits again. The tit for tat wasn't much. They launched some missiles at Jordan at U.S. bases in Jordan, but they were very quick to say, "Look, we're done. We're done. You pushed us and we pushed you back and we're going to leave it at that." Very different from the tit for tat that we had even a month ago, and I think it's really a realization on the Iranians part that escalation may not get them to where they want to go and that right now it's an economic fight, it's an economic fight for survival for the Iranians and for the U.S. in many ways, the war has been handed over to Secretary Besson to the Treasury to fight this as an economic battle. You know, we saw Senator Tant Cruz on NBC over the weekend basically back up Trump's mission accomplishment statement saying, you know, "Listen, kinetic combat operations effectively done." I mean, do you buy that then, I mean, is the military part of the war, is it over? It should be, if it's played right from here on out, but I also think that at some point there's going to have to be a resolution. The U.S. can indefinitely continue the military blockade and what they're doing in terms of facilitating transit at the strait. The Iranians can't. Their economy is in shambles, it continues to decline. They're a failed nation, they've got 350 percent inflation, they have no currency, they're not paying their soldiers. President, it's right that inflation is running rampant, but you never know how the RGC is going to continue to punish the people. Remember, these are the same people that have at least notionally gunned down tens of thousands of their own people. So, it's an economic battle. The RGC knows that if they lose, they lose power. Their biggest fear is the people coming out into the streets. But as far as where we are, it's hard to say, and it's really going to, you know, maybe five years from now we can talk about whether this war was a good idea or a bad idea, but it's certainly had repercussions for the U.S. military and the U.S. position within the region. Yeah, not to mention the casualties. I think 18 dead so far, U.S. service members, 750 more wounded. Most of those have traumatic brain injuries, according to Pentagon. Not to mention the price tag, 37 billion Pentagon said last month. But what about the straight? I mean, that is sort of at the center of the economic war you're talking about. You mentioned the present said that it's been clear to mines. We got the oil coming out. He says it's now part of America. I mean, is that true? What control of it do you actually have based on what you know? So the administration puts out one number saying, look, we put out, we're getting 15 million barrels a day through. We have the state of our moves and extremely good shape. You know, we're taking over many, many ships that got through last night, as you know. Remember Devin that it was 20 million barrels a day before the war started. So that would mean that only 5 million barrels a day are missing. And a lot of oil is coming out. That's why you haven't seen the price of oil go like they thought it might have to go. Now, the only thing that can tell us the truth is the price of oil. So WTI crew today, $80, $85. I think that if the crude price stays about that level, that that will allow the White House to say, look, it's nothing's getting worse, you know, it's not as bad as it was. And it takes a bit of the pressure off the midterms. But in terms of the oil getting out, we really have no way to know. So the US says one thing, you're on and say another, it's certainly not easy. They're having to move these ships at night, and they're having to transfer oil once they get into the Indian Ocean, and they're having to hug the coast of Oman. So it's still a very, very dangerous, very, very dangerous operation. We're seeing that some of these ships are continue to be attacked. So the president calls that a nuisance. But if you are one of those shipping companies, it's certainly not a nuisance if one of your ships gets hit. Yeah. And that's for sure. And we are already seeing not just the shipping companies make changes, but the oil companies talking about new pipelines, workarounds for the straight. I mean, that's sort of my last question, six months in. Do you get the sense that this is now going to fundamentally forever change the oil business in the world? I mean, are we in a new chapter? I mean, is the strike in a matter? Yeah, I think it's not just the oil business. I think it's the whole regional dynamic. So I think this is the high watermark of Iranian influence and Iranian power. Because as you note, every country in the Persian Gulf is now spending money on finding alternative ways to get oil out, to get their hydrocarbons out in a way where they can't be blocked the straight or remove that 20 mile. You know, each of those, each of those, those passages, those channels are only about two miles wide, Devon. So it's not hard to disrupt that. So they're doing pipelines, they're doing alternate Red Sea transportation. So I think this takes a lot of power away. Eventually, it'll decline the Iranian's power. So that's the interesting dynamic, which means that lots of other dynamics within the region shift as well. It's going to continue to be Sunni versus Shia Islam, with Iran versus the Persian Gulf countries. Now, the Turkey and Pakistan and the Saudis have made. So there's all sorts of things going on that mean that the regional dynamics are changing forever. And the new chapter in Middle East is just beginning. A lot of change, so many levels in six months. Just in terms of our outlook, our economy, military dynamics, fascinating insights. As always, Steve. Thanks so much for taking the time. Steve Ganyard, ABC News contributor. Thanks, Devon. Summer is usually pretty sleepy over at the US Supreme Court, but this one has been anything but that. A blast of emergency appeals from President Trump have kept the justice as busy and divided. Next week, of course, it was Trump's executive order on mail ballots. Yesterday, it was Trump's bid to build that massive White House ballroom. The justices did not rule on whether the construction is legal, but said the historic preservationists who challenged it likely do not have the grounds to sue. Five to four, the courts say construction can continue, but the biggest surprise, Chief Justice John Roberts joining with the three liberals in descent, calling the project likely unlawful. And now, Trump is asking the justices to urgently review his ban on transgender troops. Specifically, 29 active service members who sued to block it and now want to stay in the fight for their country while this plays out. These are folks who have been serving in some cases up to 20 years or more, and for the administration to kick them out, not based on their performance, but based on who they are. So, it's not just the lines that idea of the military as a merciless and that sends the message not just to transgender people, but to everybody. That's Michael Haley with Glad Law, one of the attorneys representing the service members who are trans men and trans women openly serving in every branch of the armed forces. He and co-counsel Shannon Mint are with the National Center for LGBTQ rights say lower courts had it right that their 29 clients should be able to keep their jobs at least for now. And an important question, whether the government can adopt policies that have such a harmful impact on our nation's military and our nation's security without having not even offering a rational justification. And our Pentagon reporter Steve Bannon joins us now. He's also an Army veteran, Steve, great to have you here. So walk me through this. what are the arguments that the Department of War is making? and making us to why these 29 service members have to be discharged immediately. The government says this is a matter of utmost importance. - Right, this is one of the first things Trump did in his second term, right when he got back in office. He executed in order to bar trans people from service. His argument was effectively, they're lying about their gender and therefore are serving dishonorably. - They're joining the military, where we're focused on the basics. We know men or men, women or women. Standards will be high. - This also comes as a secretary of defense, Pete Hexeth is reshaping Pentagon in his image. He regularly uses transgender slurs in his speeches and part of his stump speech, you can look up any video of him talking. He will probably also use the phrase, no more dudes and dresses. He has made it very clear that during his leadership, he doesn't want trans people serving. - Yeah, I mean, the cultural change for at the top over the Pentagon is something we've watched with fascination. I mean, it is dramatic from any of the more recent administrations, but let's drill down on the population that we're talking about. I mean, how many people transgender service members are actually serving now? What do we know about that group? - The estimates and court documents show there's about 4,200 trans people that have been serving in recent years across the act of duty, the reserves and national guard and these 29 that we're talking about are part of that suit. And then when Trump did his trans ban earlier on in his second term, some people did stick around for these trans service members aren't allowed to go to work. So the military has effectively been paying them to stay on leave as this case remains in limbo. - Wow, and so much of the ban broadly was allowed to take effect by the Supreme Court last year. Aside from these plaintiffs, right? I mean, how has that ban played out? I mean, they have been able to enforce it, right? - Right, I mean, the military's gone under a lot of cultural changes in recent years and this frankly, there's been some questions on the margin. So one of them is, how do we grade transgender service members on a physical fitness test, for example, the services have different standards for men and women and there's been questions. Oh, do you grade them on their biological sex or the gender that they associate with? But of all military personnel issues, this is not really cracked even in the top 50s. Not something we're hearing about from the rank and file when you hear about personnel issues, they're more concerned about safety on basis. Quality of the food, they're getting the sleep. We saw reports of morale issues on the USS Lincoln. Those are the issues that are affecting the rank and file and the commanders and this issue is coming from the administration based on what they think the military should look like. - And I imagine if this group of 29 prevails and they are the plaintiffs in this case, so they're sort of a unique status as being attached to the lawsuit. But it would be a pretty tough environment for many of them and I know they've even talked to them. They've signed up to serve and are willing to sustain that but pretty tough environment to keep serving in. - Right, and the military has had recruiting issues over the last couple of years. And so when you talk to some commanders about this issue, they'll say, hey, anyone that can make the standards should be able to join. The military going back to the Revolutionary War, there's always been a group of people in question of who can serve and what level service they can have going back to, you needed to own property in most cases in the colonial days to be an officer, you fast forward to black service members and women and gay service members and the repeal don't ask, don't tell. And most of these groups have eventually been allowed through internal policy in the military, not intervention in the courts. - Fasting stuff, I know you'll be following the case. We'll see what the Supreme Court says when they consider it later. This year, Steve Bannon, thanks so much. - Thank you for having me. - Okay, one more quick break. And when we come back, the new Maxine trend, you may not want to smell. One last thing is next. - We have a lot of technical issues. We can also talk about the current situation and the front end, and we can talk about the future. We can talk about the future and the future of the shop, and we can talk about the future of the shop. We can talk about the future of the shop, and the future of the shop, and the future of the shop, and the future of the shop. - It's Shannon Maldonado. The new Maxine's business is a very popular business in the art industry. It's a very popular business in the art industry because it's a very popular business in the art industry. We can talk about the future of the shop, and we can talk about the future of the shop, and we can talk about the future of the shop, and we can talk about it. And one last thing. You've probably heard that old adage of beauty is in the eye of the beholder. Well, when it comes to dating a new trend among some Gen Z men, at least on TikTok believes attraction has less to do with the eyes than it does the nose. Their ditching looks maxing for what they're calling pheromone maxing. The idea that showering may wash away so-called love chemicals that our bodies naturally release to send signals to people around us. The ditching not just the soap, they're skipping deodorant and cologne. And as for the science to back this up, well, there isn't much. Studies have found a link between pheromones and mating in some animal species, nothing's been proven yet among humans. Experts say liking how your partner smells is a perfectly normal thing, but that it probably isn't due to their pheromones. And showering? Well, keep it going to avoid bacteria maxing.
