Hurricane hunters chase powerful atmospheric rivers as dangerous systems slam West Coast

Atmospheric rivers are powerful storm systems that can cause intense flooding and billions of dollars in damage. 

The storms are airborne rivers of water vapor pushed by wind. Such phenomena can measure 2,000 miles long and 500 miles across, and can carry about as much water as 25 Mississippi Rivers. 

One such system is slamming into the West Coast right now, placing millions under flood alerts because of forecasts for moderate to heavy rainfall and several feet of snow in some high-altitude areas. Southern California will be drenched, and rain will even fall in the state’s deserts. 

A group of hurricane hunters is working to investigate the weather phenomenon. CBS Mornings recently joined a flight of U.S. government scientists taking off from Honolulu, Hawaii, to follow the path of an atmospheric river forming over the Pacific Ocean as part of our “Protecting the Planet” series. Those atmospheric rivers often hit the West Coast and dump extreme amounts of snow and rain. Sometimes the storms turn into systems that can travel across the country, wreaking even more havoc. Multiple atmospheric rivers last winter eradicated California’s drought, but caused $4.6 billion in damages.

“If we get too much, it’s a problem. If we get too little, it’s a problem,” said Marty Ralph, the director of the Center for Western Weather and Water Extremes at UC San Diego. Ralph has been studying atmospheric rivers for more than two decades. 

The powerful storms are expected to become even stronger as climate change heats the planet and creates a warmer atmosphere. 

“The climate models are projecting that there’s gonna be longer dry spells, but also the wettest of the wet days … the top 1% wettest days … could be a lot wetter,” Ralph said. This will cause extreme weather events to become even worse, Ralph explained. 

During the seven-hour reconnaissance mission that CBS Mornings observed, scientists from the National Oceanic and Atmospheric Administration dropped 30 instruments attached to parachutes into the storm. A scientist told CBS Mornings that those instruments will provide a constant look into the temperature, humidity, wind speed and wind direction as they travel through the storm, providing invaluable information that can’t be collected from a satellite image.

“That’s really helpful for forecasters down on the ground to be able to forecast exactly where this is going to go,” NOAA scientist Samantha Timmers said. 

NOAA says that data from flights like this has already improved the accuracy of forecasts by 10%, better pinpointing where and when storms will hit and how much rain and snow they will drop. That can save lives and better protect property, while giving reservoir operators better data to decide when to release water to make room for an upcoming storm, or hold onto it for the dry season. 

The data also helps scientists learn more about atmospheric rivers. The term was only formally defined by scientists in 2017, according to Ralph, so there’s still a lot to learn. 

“They sort of don’t look like much even when you’re flying right over them at 41,000 feet,” Ralph said. “But there’s a lot going on down there.”

Gazan chefs cook up hope and humanity for online audience

Renad Atallah is an unlikely internet sensation: a 10-year-old chef, with a repertoire of simple recipes, cooking in war-torn Gaza. She has nearly a million followers on Instagram, who’ve witnessed her delight as she unpacks parcels of food aid.

We interviewed Renad via satellite, though we were just 50 miles away, in Tel Aviv. [Israel doesn’t allow outside journalists into Gaza, except on brief trips with the country’s military.]

“There are a lot of dishes I’d like to cook, but the ingredients aren’t available in the market,” Renad told us. “Milk used to be easy to buy, but now it’s become very expensive.”

I asked, “How does it feel when so many people like your internet videos?”

“All the comments were positive,” she said. “When I’m feeling tired or sad and I want something to cheer me up, I read the comments.”

We sent a local camera crew to Renad’s home as she made Ful, a traditional Middle Eastern bean stew. Her older sister Noorhan says they never expected the videos to go viral. “Amazing food,” Noorhan said, who added that her sibling made her “very surprised!”

After more than a year of war, the Gaza Strip lies in ruins. Nearly everyone has been displaced from their homes. The United Nations says close to two million people are experiencing critical levels of hunger.

Hamada Shaqoura is another chef showing the outside world how Gazans are getting by, relying on food from aid packages, and cooking with a single gas burner in a tent.

Shaqoura also volunteers with the charity Watermelon Relief, which makes sweet treats for Gaza’s children.

In his videos online, Shaqoura always appears very serious. Asked why, he replied, “The situation does not call for smiling. What you see on screen will never show you how hard life is here.”

Before dawn one recent morning in Israel, we watched the UN’s World Food Program load nearly two dozen trucks with flour, headed across the border. The problem is not a lack of food; the problem is getting the food into the Gaza Strip, and into the hands of those who desperately need it.

The UN has repeatedly accused Israel of obstructing aid deliveries to Gaza. Israel’s government denies that, and claims that Hamas is hijacking aid.

“For all the actors that are on the ground, let the humanitarians do their work,” said Antoine Renard, the World Food Program’s director in the Palestinian territories.

I asked, “Some people might see these two chefs and think, well, they’re cooking, they have food.”  

“They have food, but they don’t have the right food; they’re trying to accommodate with anything that they can find,” Renard said.

Even in our darkest hour, food can bring comfort. But for many in Gaza, there’s only the anxiety of not knowing where they’ll find their next meal.

A study to devise nutritional guidance just for you

Avatar

Published

It’s been said the best meals come from the heart, not from a recipe book. But at this USDA kitchen, there’s no pinch of this, dash of that, no dollops or smidgens of anything. Here, nutritionists in white coats painstakingly measure every single ingredient, down to the tenth of a gram.

Sheryn Stover is expected to eat every crumb of her pizza; any tiny morsels she does miss go back to the kitchen, where they’re scrutinized like evidence of some dietary crime.

Stover (or participant #8180, as she’s known) is one of some 10,000 volunteers enrolled in a $170 million nutrition study run by the National Institutes of Health. “At 78, not many people get to do studies that are going to affect a great amount of people, and I thought this was a great opportunity to do that,” she said.

It’s called the Nutrition for Precision Health Study. “When I tell people about the study, the reaction usually is, ‘Oh, that’s so cool, can I do it?'” said coordinator Holly Nicastro.

She explained just what “precise” precisely means: “Precision nutrition means tailoring nutrition or dietary guidance to the individual.”

The government has long offered guidelines to help us eat better. In the 1940s we had the “Basic 7.” In the ’50s, the “Basic 4.” We’ve had the “Food Wheel,” the “Food Pyramid,” and currently, “My Plate.”

They’re all well-intentioned, except they’re all based on averages – what works best for most people, most of the time. But according to Nicastro, there is no one best way to eat. “We know from virtually every nutrition study ever conducted, we have inner individual variability,” she said. “That means we have some people that are going to respond, and some people that aren’t. There’s no one-size-fits-all.”

The study’s participants, like Stover, are all being drawn from another NIH study program called All Of Us, a massive undertaking to create a database of at least a million people who are volunteering everything from their electronic health records to their DNA.  It was from that All of Us research that Stover discovered she has the gene that makes some foods taste bitter, which could explain why she ate more of one kind of food than another.

Professor Sai Das, who oversees the study at Tufts University, says the goal of precision nutrition is to drill down even deeper into those individual differences. “We’re moving away from just saying everybody go do this, to being able to say, ‘Okay, if you have X, Y and Z characteristics, then you’re more likely to respond to a diet, and somebody else that has A, B and C characteristics will be responding to the diet differently,'” Das said.

It’s a big commitment for Stover, who is one of 150 people being paid to live at a handful of test sites around the country for six weeks – two weeks at a time. It’s so precise she can’t even go for a walk without a dietary chaperone. “Well, you could stop and buy candy … God forbid, you can’t do that!” she laughed.

While she’s here, everything from her resting metabolic rate, her body fat percentage, her bone mineral content, even the microbes in her gut (digested by a machine that essentially is a smart toilet paper reading device) are being analyzed for how hers may differ from someone else’s. 

Nicastro said, “We really think that what’s going on in your poop is going to tell us a lot of information about your health and how you respond to food.”

Stover says she doesn’t mind, except for the odd sounds the machine makes. While she is a live-in participant, thousands of others are participating from their homes, where electronic wearables track all kinds of health data, including special glasses that record everything they eat, activated when someone starts chewing. Artificial intelligence can then be used to determine not only which foods the person is eating, but how many calories are consumed.

This study is expected to be wrapped up by 2027, and because of it, we may indeed know not only to eat more fruits and vegetables, but what combination of foods is really best for us.  The question that even Holly Nicastro can’t answer is, will we listen? “You can lead a horse to water; you can’t make them drink,” she said. “We can tailor the interventions all day. But one hypothesis I have is that if the guidance is tailored to the individual, it’s going to make that individual more likely to follow it, because this is for me, this was designed for me.”
