Western Alaska storm and southerly flow drives warmth back into the state


ANCHORAGE, Alaska (KTUU) – Gusty winds and heavy snow has begun to spread into Western and Southwest Alaska, with a surge of warmer air. Temperatures in Southwest Alaska is already 10 to 35 degrees warmer than yesterday morning. This warmth will spread across the rest of the state through the weekend, with some of the most pronounced warmth along the Slope. We’ll see many areas this weekend into next week remaining well-above average.

SOUTHCENTRAL:

Temperatures are slowly warming across Southcentral, with many areas seeing cloud coverage increasing. While we could see some peeks of sunshine today, most locations will see mostly cloudy conditions. While we can’t rule out light flurries for inland locations, most of the precipitation today will occur near the coast. Snow looks to be the primary precipitation type, although later this evening a transition to rain or wintry mix will occur. This comes as temperatures quickly warm across Southcentral.

We’ll see highs today in the upper 20s and lower 30s for inland areas, while coastal regions warm into the 30s and 40s. The southerly flow aloft will remain with us for several days, pumping in the warmth and moisture. As a result, Kodiak could see over an inch of rain today, with gusty winds.

While most of the precipitation this weekend remains near the coast, inland areas will see the best chance for wintry mix Sunday into Monday. Little to no accumulation is expected.

The key takeaways for this weekend, is snow transitioning to rain, with some gusty winds likely for parts of Southcentral this weekend.

SOUTHEAST:

Another fairly quiet day is expected across Southeast today, outside of some light snow near Yakutat. We’ll see a mix of sun and clouds with temperatures remaining on the cooler side. Parts of the Northern Panhandle may stay in the upper 20s today. The stretch of quiet weather will stay with us through the first half of Saturday, followed by an increase in precipitation and winds. This upcoming system may bring some heavy snowfall to Southeast, so be prepared for that potential this weekend. Temperatures warm into next week, back into the upper 30s and lower 40s for many areas.

INTERIOR:

While temperatures this morning have bottomed out as low as -30 near Fort Yukon, temperatures will warm into the weekend. A wind advisory for the Alaska Range goes into effect at 9 Friday morning, where winds up to 60 mph will warm the Interior. Temperatures today for many locations will warm into the single digits, with some of the greatest warming arriving Saturday through next week. It’s likely we’ll spend most of next week with temperatures in the 20s and 30s, with the warmest locations near the Alaska Range. While we will largely stay dry, there is a chance for some light snow arriving Sunday night into Monday.

SLOPE/WESTERN ALASKA:

Temperatures will remain slightly above average for parts of the Slope today, with warming winds to build into the Slope this weekend. This comes as our area of low pressure in the Bering Sea continues to move farther north. Be prepared for gusty easterly winds along the Slope, leading to blowing snow and reduced visibility. We’ll see temperatures quickly warm well above average, with highs climbing into the 20s and 30s along the Slope into next week. While some snow is possible through the weekend, the heaviest activity will occur for the Brooks Range. We’ll see the potential for 4 to 12 inches of snowfall, with the highest amounts occurring along the southern slopes of the Brooks Range near Kobuk Valley. Winds could gusts as high as 45 mph, leading to greatly reduced visibility.

Heavy snow is impacting Western and Southwest Alaska this morning, with winds gusting up to 50 mph. Numerous winter weather alerts, as well as a coastal flood advisory is in effect. The heaviest snow will fall for the Seward Peninsula and east of Norton Sound, where up to a foot or more of snow is to be expected. The heaviest amounts will fall today, with the activity set to lighten up through Sunday. In addition to the snow, gusty winds will lead to areas of blowing snow. Visibility could be reduced down to less than half a mile at times. As southerly flow continues to pump in warmth, we’ll see a transition from snow to rain later today into Saturday for parts of Southwest Alaska.

ALEUTIANS:

Gusty winds and heavy rain will fall through the Aleutians today, where up to .75″ of rain is possible. As the area of low pressure moves north, we’ll see a new low form just south of the Eastern Aleutians. This will lead to additional rain and winds into the weekend. Winds could gusts upwards of 50 mph through the Eastern Aleutians and through the Alaska Peninsula. With ridging to our east, more rain and winds remain with us into early next week. There is the potential that the Pribilof Islands see a return to snow Sunday, as colder air moves into the Bering Sea.

OUTLOOK AHEAD:

Well above average warmth will stay with us as we close out January. While one more short-lived cold snap is possible, we may have to wait until February before we tap into warmer conditions. Temperatures through the close of January will keep average monthly temperatures 5 to 12 degrees above average for much of the state. The overall trend still favors a wetter pattern, although with warmer weather the southern parts of the state will favor more rain or a mixed bag of precipitation.

Have a wonderful and safe holiday weekend.

Alaska governor, ally of Trump, will keep flags at full-staff for Inauguration Day • Alaska Beacon


Alaska will join several other Republican-led states by keeping flags at full-staff on Inauguration Day despite the national period of mourning following President Jimmy Carter’s death last month.

Gov. Mike Dunleavy announced his decision, which breaks prior precedent, in a statement on Thursday. It applies only to flags on state property. Flags on federal property are expected to remain at half-staff.

Flags on state property will be returned to half-staff after Inauguration Day for the remainder of the mourning period.

The governors of Indiana, Idaho, Iowa, Texas, Florida, Tennessee, Oklahoma, North Dakota, Nebraska, Montana and Alabama, among others, have announced similar moves.

U.S. Speaker of the House Mike Johnson, a Republican from Louisiana, said on Tuesday that flags at the U.S. Capitol would remain at full-staff on Inauguration Day. 

Their actions follow a statement from President-elect Donald Trump, who said in a Jan. 3 social media post that Democrats would be “giddy” to have flags lowered during his inauguration, adding, “Nobody wants to see this, and no American can be happy about it. Let’s see how it plays out.”

Dunleavy is seen as a friend of the incoming president and has met with him multiple times over the past year. Dunleavy and 21 other Republican governors visited Trump last week in Florida at an event that Trump described as “a love fest.”

Since 1954, flags have been lowered to half-staff during a federally prescribed 30-day mourning period following presidential deaths. In 1973, the second inauguration of President Richard Nixon took place during the mourning period that followed the death of President Harry Truman. 

Then-Gov. Bill Egan made no exceptions for Alaska, contemporary news accounts show, and no exception was made for Nixon’s inauguration in Washington, D.C., either.

A spokesperson for Dunleavy’s office said the new precedent is designed to be a balance between honoring the ongoing mourning period for former President Jimmy Carter and recognizing the importance of the peaceful transition of power during the presidential inauguration. 

“Temporarily raising the flags to full-staff for the inauguration underscores the significance of this democratic tradition, while returning them to half-staff afterward ensures continued respect for President Carter’s legacy,” the spokesperson said.

Federal disaster declaration approved for Northwest Alaska flooding


ANCHORAGE, Alaska (KTUU) – President Joe Biden announced the approval of federal disaster assistance on Thursday for recovery efforts in areas that sustained damage from flooding and storms in October 2024.

Those areas include the Bering Strait Regional Educational Attendance Area (REAA) and the Northwest Arctic Borough area where many structures were damaged by a severe storm from Oct. 20-23, 2024.

Arctic hotspots study reveals areas of climate stress in Northern Alaska and Siberia

Ecological warning lights have blinked on across the Arctic over the last 40 years, according to new research, and many of the fastest-changing areas are clustered in Siberia, the Canadian Northwest Territories, and Alaska.

An analysis of the rapidly warming Arctic-boreal region, published in Geophysical Research Letters, provides a zoomed-in picture of ecosystems experiencing some of the fastest and most extreme climate changes on Earth.

Many of the most climate-stressed areas feature permafrost, or ground that stays frozen year-round, and has experienced both severe warming and drying in recent decades.

To identify these “hotspots,” a team of researchers from Woodwell Climate Research Center, the University of Oslo, the University of Montana, the Environmental Systems Research Institute (Esri), and the University of Lleida used more than 30 years of geospatial data and long-term temperature records to assess indicators of ecosystem vulnerability in three categories: temperature, moisture, and vegetation.

Building on assessments like the NOAA Arctic Report Card, the research team went beyond evaluating isolated metrics of change and looked at multiple variables at once to create a more complete, integrated picture of climate and ecosystem changes in the region.

“Climate warming has put a great deal of stress on ecosystems in the high latitudes, but the stress looks very different from place to place and we wanted to quantify those differences,” said Dr. Jennifer Watts, Arctic program director at Woodwell Climate and lead author of the study.

“Detecting hotspots at the local and regional level helps us not only to build a more precise picture of how Arctic warming is affecting ecosystems, but to identify places where we really need to focus future monitoring efforts and management resources.”

The team used spatial statistics to detect “neighborhoods,” or regions of particularly high levels of change during the past decade.

“This study is exactly why we have developed these kinds of spatial statistic tools in our technology. We are so proud to be working closely with Woodwell Climate on identifying and publishing these kinds of vulnerability hotspots that require effective and immediate climate adaptation action and long-term policy,” said Dr. Dawn Wright, chief scientist at Esri. “This is essentially what we mean by the ‘Science of Where.’”

The findings paint a complex and concerning picture.

The most substantial land warming between 1997–2020 occurred in the far eastern Siberian tundra and throughout central Siberia. Approximately 99% of the Eurasian tundra region experienced significant warming, compared to 72% of Eurasian boreal forests.

While some hotspots in Siberia and the Northwest Territories of Canada grew drier, the researchers detected increased surface water and flooding in parts of North America, including Alaska’s Yukon-Kuskokwim Delta and central Canada. These increases in water on the landscape over time are likely a sign of thawing permafrost.

Among the 20 most vulnerable places the researchers identified, all contained permafrost.

“The Arctic and boreal regions are made up of diverse ecosystems, and this study reveals some of the complex ways they are responding to climate warming,” said Dr. Sue Natali, lead of the Permafrost Pathways project at Woodwell Climate and co-author of the study.

“However, permafrost was a common denominator—the most climate-stressed regions all contained permafrost, which is vulnerable to thaw as temperatures rise. That’s a really concerning signal.”

For land managers and other decisionmakers, local and regional hotspot mapping like this can serve as a more useful monitoring tool than region-wide averages. Take, for instance, the example of COVID-19 tracking data: maps of county-by-county wastewater data tend to be more helpful tools to guide decision making than national averages, since rates of disease prevalence and transmission can vary widely among communities at a given moment in time.

So, too, with climate trends: local data and trend detection can support management and adaptation approaches that account for unique and shifting conditions on the ground.

The significant changes the team detected in the Siberian boreal forest region should serve as a wakeup call, said Watts.

“These forested regions, which have been helping take up and store carbon dioxide, are now showing major climate stresses and increasing risk of fire. We need to work as a global community to protect these important and vulnerable boreal ecosystems, while also reining in fossil fuel emissions.”
