‘Arctic front' potentially deadly for those living outside — here's what to look for
Arctic front arriving driving temperatures down
The last major cold snap Austin experienced in January resulted in at least 12 cold exposure calls, including two 'fatal incidents,' according to Austin-Travis County EMS.
The city of Austin's Homeless Strategy Office (HSO) used its text alert system to push out information about the overnight cold weather shelters and inform people about the danger of frostbite and hypothermia.
Signs of frostbite may include:
Initially, one may experience redness or pain of skin
Other signs include a white or grayish-yellow skin that feels 'unusually firm or waxy'
Numbness
Signs of hypothermia include:
Exhaustion
Confusion, memory loss or slurred speech
Drowsiness
The city said hypothermia happens 'at very cold temperatures, but can occur at cool temperatures (40°F) if a person is wet (from rain, sweat or cold water) and becomes chilled.' You can find more information about hypothermia here.
Those conditions are projected to take place overnight. You can find details on how to get to overnight cold weather shelter here.
Happening this winter, Austin-Travis County EMS and Central Health — Travis County's health care district — have partnered on a bridge clinic program. It may very well come into play during winter weather like this.
Central Health, EMS partner on 'bridge' care model for people experiencing homelessness
The bridge clinic is a place for people experiencing homelessness that need specialized and inexpensive care, that may otherwise end up in an emergency room or jail. Most of the patients of the clinic are brought in by EMS. That clinic has been open since late last year.
'It's really designed for people experiencing homelessness or who are otherwise vulnerable or marginalized, who are disconnected from our care system who we can rapidly engage in care,' said Dr. Tim Mercer, co-director of high-risk populations at Central Health.
The bridge clinic off Interstate 35 does not currently have extended hours during winter events like this, but for people who may end up with hypothermia, frostbite or even need an amputation due to cold weather, the bridge clinic is where folks may end up to get a follow-up or long-term treatment.

The bridge clinic will also be an option in the coming days as an alternative to the emergency room.

Scientists discover changes to the polar vortex that are plunging parts of US into deep freeze
When you buy through links on our articles, Future and its syndication partners may earn a commission. Though global temperatures are warming, winters in the Northern Hemisphere are still marked by cold snaps and extreme snowfall events — sometimes to an unprecedented extent, such as the 2021 deep freeze in Texas and Oklahoma that caused over $1 billion in damage. Now, a new study suggests that these cold extremes are due to an increasingly common pattern in the polar vortex, the zone of low pressure that usually circulates over the Arctic. Disruptions to this vortex cause it to deform and stretch, spewing cold air into Canada and the U.S. These disruptions are becoming more common as the Arctic warms. "Overwhelmingly, extreme cold and severe winter weather, heavy snowstorms and deep snow, are associated with these stretched events," study co-author Judah Cohen, the director of seasonal forecasting at Atmospheric and Environmental Research and a visiting scientist at MIT, told Live Science. Cohen and his team looked at how these events evolve in the stratosphere, the middle layer of the atmosphere that starts about 12 miles (19 kilometers) up. Understanding how these patterns shift could help meteorologists make longer-range forecasts, said Andrea Lopez Lang, an atmospheric scientist at the University of Wisconsin—Madison who was not involved in the research. "Knowing this information is useful for a lot of applications in energy [and] applications in insurance or reinsurance," Lang told Live Science. "How cold is it going to get? Are pipes going to burst? Are insurance claims going to spike this winter?" Usually, the polar vortex circulates around the North Pole like a spinning top. Occasionally, it collapses dramatically, which usually leads to polar air rushing toward northern Europe and Asia. These collapses can sometimes cause cold snaps in North America — but not always. "There's been this big question mark over what happens in North America," Lang said. Related: US suffers record-breaking cold: What's going on with the polar vortex? Cohen and his colleagues looked at stratosphere data from satellite observations between 1980 and 2021, as well as winter weather records from the same period. They found that, short of total collapse, the polar vortex often wobbles and stretches, like a figure skater flinging out an arm for balance in a tricky spin. There were five different common patterns in the stratosphere, the researchers reported in the journal Science Advances on July 11, and two in particular were linked to cold weather dipping into Canada and the U.S. during these stretch events. Stretch events are increasing in general, Cohen said, but there has also been a shift in the type of stretches. One of the stratospheric patterns tends to bring cold air toward the East Coast, while the other creates a chill in the Midwest and Plains region. Since 2015, the researchers found, the westerly pattern has been more common. It's not entirely clear why, but this shift seems to be associated with La Niña, a pattern of unusually cold temperatures to the equatorial Pacific Ocean. In the last couple of decades, there have been multiple multiyear La Niña events. The researchers were able to detect some regularities in the way the polar vortex shifts between the five patterns, which might help improve forecasts over the two- to six-week period, Cohen said. "In that shorter range is the poorest accuracy," he said. "This paper can be helpful in that timeframe." RELATED STORIES —La Niña is dead — what that means for this year's hurricanes and weather —Can cold weather make you sick? —Antarctic sea ice collapse linked to a mysterious spike in ocean salt One big question is how these polar vortex trends might change over time as the globe warms, Lang said. Cohen and his team have been looking at that question as well. The polar vortex is controlled by waves in the atmosphere, he said, and right now the most influential standing waves is over Eurasia, with a warm ridge to the west and a cooler trough to the east, which in turn is driven by patterns of warming in the Arctic. Currently, melting sea ice is increasing the temperature differences between west and east, strengthening the wave that can disrupt the vortex, Cohen said. If the sea ice disappeared, the pattern might collapse and flip. Instead of surprisingly cold winter events despite overall global warming, winter might suddenly become much toastier. "We could become more like the Southern Hemisphere where you rarely get a breakdown of the polar vortex," Cohen said, "and it would probably mean warmer midlatitudes and a colder Arctic."

Warming waters raise toxic algae levels in Arctic whales
Arctic whales are ingesting higher levels of toxic algae as warming waters create more suitable conditions for microorganisms to thrive, according to newly published NOAA research. That poses risks for those who hunt and consume the whales. The study, published in Nature, found that 'potent neurotoxins' that can cause serious illness and death in humans are increasingly present in fecal samples from bowhead whales that live in Arctic and sub-Arctic waters, including areas with sea-ice coverage. Researchers affiliated with NOAA's Northwest Fisheries Science Center found the prevalence and concentrations of two forms of toxins produced by algae — domoic acid and saxitoxin — in whale feces 'increased significantly' between 2004 and 2022, a period of rapid warming in the Arctic that continues today. Advertisement 'This is like a sleeping giant awakening,' Kathi Lefebvre, a research scientist at NOAA Fisheries' Northwest Fisheries Science Center and the study's lead author, said in a release. 'These are new risks that were previously unknown.'

Data: Kerr County sent first targeted alert two days after deadly flood
HUNT, Texas (KXAN) — Federal Emergency Management Agency (FEMA) data does not show a record of Kerr County officials issuing a locally targeted emergency alert to warn people in the area of the rapidly rising waters until two days after the deadly flood. The emergency flash flood warnings issued on July 4 and 5 came from the National Weather Service, which were distributed through CodeRED, a mass notification system that requires members of the public to register to receive alerts. As Kerr County leaders avoid alert questions, new audio surfaces in CodeRED timeline Records show the earliest warnings of the flash floods, which claimed more than 100 lives in Kerr County alone as of July 15, were issued by the NWS at 1:14 a.m. on July 4, telling people to move to higher ground. The county shared a San Antonio meteorologist's post on Facebook at 5:31 a.m. on July 4. County officials added their warning to the shared post, saying, 'Flooding along the Guadalupe River is happening now. Be safe and move to higher ground. Do not drive through water. Turn Around – Don't Drown!' After the initial alert at 1:14 a.m., an additional 21 flash flood alerts were issued by the NWS on July 4 in Kerr County, according to archived alert data. FEMA records indicate that the county itself never issued an alert on July 4 about the dangerous flash flooding through the Integrated Public Alert & Warning System (IPAWS), which can alert all phones in a geographical area, regardless of whether a person has enrolled for emergency alerts. Sheriff hints at 'after action' review, as records reveal warning of 'worst-case flood event' KXAN reached out to Kerr County officials about the timing of their alerts. This story will be updated when a response is received. Contrary to alerts issued by the NWS, IPAWS provides authorities the ability to write their own warning message, which is delivered through multiple communication pathways 'to reach as many people as possible to save lives and protect property,' according to FEMA. 'Utilizing multiple pathways for public alerts increases the likelihood that the message will successfully reach the public,' according to FEMA. The only IPAWS alerts Kerr County issued occurred on July 6 and July 13 due to the 'high probability' and 'high confidence' of river flooding, according to FEMA IPAWS data. Records show these Kerr County IPAWS alerts classified the severity of the weather events as 'Extreme' and the presence of an 'Imminent Threat' with headlines stating 'Evacuation Immediate' and 'Local Area Emergency.' According to FEMA IPAWS alert data, Kerr County Emergency Management Coordinator William 'Dub' Thomas is the person who authorized and issued the IPAWS alerts. KXAN reached out to Thomas for additional details regarding the alerts he authorized. A county commission meeting video from Nov. 16, 2020, shows Thomas advocating for the emergency alert system as lifesaving shortly before the commissioner approved the measure.
