JUNEAU, Alaska (AP) — The gray, two-story home with white trim toppled and slid, crashing into the river below as rushing waters carried off a bobbing chunk of its roof. Next door, a condo building teetered on the edge of the bank, its foundation already having fallen away as erosion undercut it.

The destruction came over the weekend as a glacial dam burst in Alaska’s capital, swelling the levels of the Mendenhall River to an unprecedented degree. The bursting of such snow-and-ice dams is a phenomenon called a jökuhlaup, and while it’s relatively little-known in the U.S., researchers say such glacial floods could threaten about 15 million people around the world.

“We sat down there and were just watching it, and all of a sudden trees started to fall in,” Amanda Arra, whose house continued hanging precariously over the river bank Monday, told the Juneau Empire. “And that’s when I started to get concerned. Tree after tree after tree.”

The flooding in Juneau came from a side basin of the awe-inspiring Mendenhall Glacier, which acts as a dam for the rain and melted snow that collect in the basin during the spring and summer. Eventually, the water gushed out from under the glacier and into Mendenhall Lake, from which it flowed down the Mendenhall River.

Water released from the basin has caused sporadic flooding since 2011. But typically, the water releases more slowly, over a number of days, said Eran Hood, a University of Alaska Southeast professor of environmental science.

Saturday’s event was astonishing because the water gushed so quickly, raising the river’s flows to about 1 1/2 times the highest previously recorded — so much that it washed away sensors that researchers had placed to study the glacial outburst phenomenon.

“The flows were just way beyond what anything in the river could withstand,” Hood said.

Two homes were completely lost and a third partially so, Robert Barr, Juneau’s deputy city manager, said Monday. There were no reports of injuries or fatalities.

Eight buildings, including those that fell into the water, have been condemned, but some might be able to be salvaged by substantial repairs or bank stabilization, he said. Others suffered lesser damage.

While climate change is melting the Mendenhall and other glaciers around the world, its relationship to such floods is complicated, scientists say.

The basin where the rain and meltwater collect was formerly covered by the Suicide Glacier, which used to flow into the Mendenhall Glacier, contributing ice to it. But the Suicide Glacier has retreated as the climate warms, leaving a lake in the basin dammed by the Mendenhall.

While that part can be linked to climate change, the unpredictable ways that those waters can burst through the ice dams and create floods downstream is not, they said.

“Climate change caused the phenomenon, but not the individual floods,” Hood said.

The variability in the timing and volume of such floods makes it hard to prepare for them, said Celeste Labedz, an environmental seismologist at the University of Calgary.

More than half of the people at risk from glacial outburst floods are in just four countries — India, Pakistan, Peru and China, according to a study published this year in Nature Communications.

One of the more devastating such events killed up to 6,000 people in Peru in 1941. A 2020 glacial lake outburst flood in British Columbia, Canada, caused a surge of water about 330 feet (100 meters) high, but no one was hurt.

Because the ground along the Mendenhall River is largely made up of loose glacial deposits, it’s especially susceptible to erosion, Hood said. The damage could have been much worse if the flood coincided with heavy rains, he said.

Chris and Bob Winter built their house about 50 feet (15.2 meters) off the Mendenhall River in 1981. It flooded for the first time in 2014, an event that prompted them to raise their house 3 feet. It flooded again on Saturday with about 3 inches of standing water, enough to soak the carpets, subflooring and drywall.

“You just got to rip it all out,” Chris Winter said. “I just don’t know what’s going to happen, but we can’t live in our house right now.”

She said her biggest concern is that they are both in their mid-70s and will probably have to move south at some point.

“We raised our family, and they’re gone and nobody’s in Juneau,” she said. “And I don’t know that we’ll be able to sell it.”

Federal funds will help DOT study wildlife crashes on Glenn Highway

Federal funds will help DOT study wildlife crashes on Glenn Highway


New federal funds will help Alaska’s Department of Transportation develop a plan to reduce vehicle collisions with wildlife on one of the state’s busiest highways.

The U.S. Transportation Department gave the state a $626,659 grant in December to conduct a wildlife-vehicle collision study along the Glenn Highway corridor stretching between Anchorage’s Airport Heights neighborhood to the Glenn-Parks Highway interchange.

Over 30,000 residents drive the highway each way daily.

Mark Eisenman, the Anchorage area planner for the department, hopes the study will help generate new ideas to reduce wildlife crashes on the Glenn Highway.

“That’s one of the things we’re hoping to get out of this is to also have the study look at what’s been done, not just nationwide, but maybe worldwide,” Eisenman said. “Maybe where the best spot for a wildlife crossing would be, or is a wildlife crossing even the right mitigation strategy for these crashes?”

Eisenman said the most common wildlife collisions are with moose. There were nine fatal moose-vehicle crashes on the highway between 2018 and 2023. DOT estimates Alaska experiences about 765 animal-vehicle collisions annually.

In the late 1980s, DOT lengthened and raised a downtown Anchorage bridge to allow moose and wildlife to pass underneath, instead of on the roadway. But Eisenman said it wasn’t built tall enough for the moose to comfortably pass through, so many avoid it.

DOT also installed fencing along high-risk areas of the highway in an effort to prevent moose from traveling onto the highway.

Moose typically die in collisions, he said, and can also cause significant damage to vehicles. There are several signs along the Glenn Highway that tally fatal moose collisions, and he said they’re the primary signal to drivers to watch for wildlife.

“The big thing is, the Glenn Highway is 65 (miles per hour) for most of that stretch, and reaction time to stop when you’re going that fast for an animal jumping onto the road is almost impossible to avoid,” he said.

The city estimates 1,600 moose live in the Anchorage Bowl.

Flight attendant sacked for twerking on the job: ‘What’s wrong with a little twerk before work’

Flight attendant sacked for twerking on the job: ‘What’s wrong with a little twerk before work’


They deemed the stunt not-safe-for-twerk.

An Alaska Airlines flight attendant who was sacked for twerking on camera has created a GoFundMe to support her while she seeks a new berth.

The crewmember, named Nelle Diala, had filmed the viral booty-shaking TikTok video on the plane while waiting two hours for the captain to arrive, A View From the Wing reported.

“I never thought a single moment would cost me everything,” wrote the ex-crewmember. TikTok / @_jvnelle415

She captioned the clip, which also blew up on Instagram, “ghetto bih till i D-I-E, don’t let the uniform fool you.”

Diala was reportedly doing a victory dance to celebrate the end of her new hire probationary period.

Unfortunately, her jubilation was short-lived as Alaska Airlines nipped her employment in the bum just six months into her contract.

The fanny-wagging flight attendant feels that she didn’t do anything wrong.

Diala was ripped online over her GoFundMe page. GoFundMe

Diala has since reposted the twerking clip with the new caption: “Can’t even be yourself anymore, without the world being so sensitive. What’s wrong with a little twerk before work, people act like they never did that before.”

The new footage was hashtagged #discriminationisreal.

The disgraced stewardess even set up a GoFundMe page to help support the so-called “wrongfully fired” flight attendant until she can land a new flight attendant gig.

“I never thought a single moment would cost me everything,” wrote the ex-crewmember. “Losing my job was devastating.”

“Can’t even be yourself anymore, without the world being so sensitive,” Diala wrote on TikTok while reacting to news of her firing. “What’s wrong with a little twerk before work, people act like they never did that before.” Getty Images

She claimed that the gig had allowed her to meet new people and see the world, among other perks.

While air hostessing was ostensibly a “dream job,” Diala admitted that she used the income to help fund her “blossoming lingerie and dessert businesses,” which she runs under the Instagram handles @cakezncake (which doesn’t appear to have any content?) and @figure8.lingerie.

As of Wednesday morning, the crowdfunding campaign has raised just $182 of its $12,000 goal.

Diala was ripped online for twerking on the job as well as her subsequent GoFundMe efforts.

“You don’t respect the uniform, you don’t respect your job then,” declared one critic on the popular aviation-focused Instagram page The Crew Lounge. “Terms and Conditions apply.”

“‘Support for wrongly fired flight attendant??’” mocked another. “Her GoFund title says it all. She still thinks she was wrongly fired. Girl you weren’t wrongly fired. Go apply for a new job and probably stop twerking in your uniform.”

“The fact that you don’t respect your job is one thing but doing it while in uniform and at work speaks volumes,” scoffed a third. “You’re the brand ambassador and it’s not a good look.”

As Alaska sees a spike in Flu cases — another virus is on the rise in the U.S.

As Alaska sees a spike in Flu cases — another virus is on the rise in the U.S.


FAIRBANKS, Alaska (KTUU) – Alaska has recently seen a rise in both influenza and respiratory syncytial virus, better known as RSV. Amidst the spike in both illnesses, norovirus has also been on the rise in the United States. The Centers for Disease Control and Prevention (CDC) says it’s highly contagious and hand sanitizers don’t work well against it.

Current data for Alaska shows 449 influenza cases and 262 RSV cases for the week of Jan. 4. Influenza predominantly impacts the Kenai area, the Yukon-Kuskokwim Delta, and the Northwest regions of the state. RSV is also seeing significant activity in the Yukon-Kuskokwim Delta and Anchorage.

Both are respiratory viruses that are treatable, but norovirus — which behaves like the stomach flu according to the CDC — is seeing a surge at the national level. It “causes acute gastroenteritis, an inflammation of the stomach or intestines,” as stated on the CDC webpage.

This virus is spread through close contact with infected people and surfaces, particularly food.

“Basically any place that people aggregate in close quarters, they’re going to be especially at risk,” said Dr. Sanjay Gupta, CNN’s Chief Medical Correspondent.

Preventing infection is possible but does require diligence. Just using hand sanitizer “does not work well against norovirus,” according to the CDC. Instead, the CDC advises washing your hands with soap and hot water for at least 20 seconds. When preparing food or cleaning fabrics — the virus “can survive temperatures as high as 145°F,” as stated by the CDC.

According to Dr. Gupta, its proteins make it difficult to kill, leaving many cleaning methods ineffective. To ensure a given product can kill the virus, he advises checking the label to see if it claims it can kill norovirus. Gupta said you can also make your own “by mixing bleach with water, 3/4 of a cup of bleach per gallon of water.”

For fabrics, it’s best to clean with water temperatures set to hot or steam cleaning at 175°F for five minutes.

As for foods, it’s best to throw out any items that might have norovirus. As a protective measure, it’s best to cook oysters and shellfish to a temperature greater than 145°F.

Based on Alaska Department of Health data, reported COVID-19 cases are significantly lower than this time last year.
