Early major damage reports coming in from greenfield, iowa, where as you can see, homes have been demolished. Iowa, along with parts of minnesota and western illinois facing what the Weather Service is calling a particularly dangerous situation. Flood watches in effect for some of those same areas tonight. Maggie vespa and her team are in the storm zone. Maggie, there is destruction across iowa tonight . Reporter yeah, lester, the strength of these storms was once again striking. And weve just learned, as you said, Authorities Say one person here in iowa was killed. Meanwhile, our team here in des moines took shelter in our hotels basement for the better part of the last hour, as this latest round of violent tornadoes tore through. That thing is growing. Reporter tonight, the onslaught continues with more tornadoes barreling across america. Late today, at least 12 twisters reported and counting, all in iowa. Everybody take cover. Tornado warnings. Everybody take cover. Unfortunately, it may have just hit a farm as well down here. And again, this just highlights the fact that you need to take these warnings very seriously. Reporter this one with potentially multiple vortexes touching down near greenfield, southwest of des moines. Storm chasers also hitting torrential rain and hail. As they drive, alarms blaring. Minutes later, coming upon jawdropping damage, with homes shredded, pieces of them tossed on top of cars. An entire neighborhood is gone. And for millions, the threat just beginning. Tonight, 50 Million People from texas to michigan are once again in mother natures line of fire for severe storms, including wind gusts up to 90 miles per hour, large hail, and possible tornadoes. A danger all too familiar amid a relentless spring. As the supercell storms that spawned tornadoes become more common, close to 300 tornadoes have been reported this month. April had close to 400, twice the average. Tonight, another round unleashing as we speak. Maggie vespa, nbc news, des moines, iowa. And bill karins is watching it all. Bill, another dangerous night ahead. Lester, weve already had two violent tornadoes, and the fear is we could have a couple more. Conditions are right for that. We head to greenfield, the one we showed the pictures of where the neighborhood is just destroyed. We also recently had a very strong tornado just north of the des moines area. As we go throughout the next couple of hours, were going take the line of storms through eastern iowa. Were talking about areas like waterloo, cedar rapids, the quad cities. These are all locations where we could deal with strong tornadoes later on tonight. A wider view shows isolated tornadoes are possible up to midnight in southern wisconsin and all the way down into oklahoma until about 11 00 p. M. This evening. Tomorrow the tornado risk is lower, but its not zero. From areas of dallas to little rock, we have an isolated chance of a strong tornado or two, large hail and damaging winds. This threat tonight, though, lester, very scary. All right, bill karins, thank you. Harrowing stories from aboard a Singapore Airlines jet that killed one passenger and injured dozens after a rare encounter with severe turbulence so violent it sent people who werent belted in hurtling into the ceiling. Senior correspondent tom costello reports. Reporter on the tarmac in bangkok, a mass casualty response to a terrifying High Altitude flight. Singapore Airlines Says at least 30 injured, some critically. A local hospital says its treating 71 passengers. One person died. The airport general manager says a 73yearold british man apparently suffered a heart attack. It happened when the boeing 777 flying from london to singapore hit sudden turbulence on the edge of a powerful storm over thailand. Flight radar 24 data shows the plane bucking like a bronco at 37,000 feet, climbing and falling. Then a controlled emergency descent to 31,000 feet. Photos from inside the cabin show the damage and chaos. Overhead panels ripped off. Food and bottles scattered on the floor, blood stains on the ceiling. Multiple victims evacuated on backboards. It was an incredibly scary experience, seeing other people on the flight who were badly injured. Reporter atmospheric researchers report clear air turbulence has only gotten worse with climate change. So we know that the amount of wind shear in the jet stream is now 15 stronger than it was when satellites first began observing it in the 1970s. Reporter heat makes the jet stream more volatile and difficult to predict. Pilots do rely on other pilots to report turbulence that they encounter. Reporter it happens every day, 5,500 times a year. Seven were injured in march of 2023 when a lufthansa flight hit severe turbulence over tennessee. In december 22, three dozen injured on a hawaiian air flight. Broken backs, broken skulls, brain injuries. A severed limb. And these are very serious conditions. And tom, unpredictable turbulence is why the airlines always say wear your seat belt. Reporter yeah, thats right. And infants should be in car seats on planes. Parents need to know that. The ntsb is sending a team to assist in the investigation. The airline says four americans were also on board this flight. Lester . All right, tom costello with that, thank you. The testimony is over tonight in former President Trumps hush money trial, with closing arguments not scheduled until next week. The defense wrapping its case without calling mr. Trump to testify. Laura jarrett reports. Reporter tonight, the defense resting its case with former President Trump choosing not to take the stand in his first criminal trial. Jurors left today hearing only from robert costello, a lawyer who briefly advised Michael Cohen. Prosecutors today again trying to paint costello is a trumpallied emissary dispatched by Rudy Giuliani to prevent cohen from flipping on mr. Trump. Confronted with emails suggesting he was frustrated cohen refused to hire him, including one where he wrote, quote, cohen, quote, continues to slow play us and the president. Is he totally nuts . He is playing with the most powerful man on the planet. Costello suggested monday cohens entire story, that former President Trump plotted to protect Stormy Daniels to protect his campaign was all a lie. Costello telling jurors that Michael Cohen said numerous times that President Trump knew nothing about those payments, and that cohen said he did this on his own. Costello only one of two witnesses called by the defense team. The testimony all told running just over 90 minutes. Theres no crime. Theres no crime. Its a kangaroo court. Theres never been anything like this that ive ever seen. Reporter the judge working with both sides for hours today to hash out critical instructions jurors will receive next week to aid their deliberations on the 34 counts mr. Trump faces for allegedly falsifying his business records. The outcome likely to largely come down to whether jurors believe cohen, the only witness to testify that mr. Trump directed the payoff to daniels and then disguised his reimbursements to cohen, all of which mr. Trump denies. The defense spent three days grilling cohen, who has been convicted of lying under oath and was disbarred. If found guilty on the lowlevel felonies here, mr. Trump faces anywhere from four years in prison to just probation. And laura, in a separate case, there is a headline today about former trump attorney Rudy Giuliani. Reporter yes, lester. Giuliani pleaded not guilty when he appeared virtually in Arizona State court today in a case where hes been tried for his efforts to try to overturn the last election, including by submitting fake documents to congress, saying that mr. Trump had won. Now mr. Trump has not been charged in that case, but he is listed as an unindicted coconspirator. Lester . Laura jarrett, thank you.
