More than 700 inches of snow have fallen at Mammoth Mountain, almost burying entire houses and setting new record for snowfall. The snowfall in the Sierra Nevada range will help mitigate drought conditions in coming years.

Atmospheric river boosted California's snowpack, especially in Central and Southern Sierra. Now the levels are record level creating safety issues such as roofs collapsing and helping with drought conditions across the western states.

A scientist explains the interaction between "rain-on-snow" events and California's snowpack in Northern California.

Libraries at two Anchorage elementary schools — Klatt and Spring Hill — were closed after the maintenance department identified ceiling damage. The district also decided “out of an abundance of caution” to proactively close the libraries of Bear Valley Elementary, Fire Lake Elementary, and Ravenwood Elementary, which share the same building design with Klatt and Spring Hill.

In addition to blizzard conditions, Kotzebue residents have been experiencing power outages, water service interruptions and travel complications because of the storms.

Engineers caution that residents wanting to clear their own roofs face greater risk of hurting themselves or damaging roofs than from a collapse.

Six weeks after a series of snowstorms dumped more than three feet of snow, bus stops along a handful of state-maintained roads remain buried, forcing transit users to navigate deep, slippery drifts and towers of snow.

Climatologist Rick Thoman says climate change is driving this more extreme winter snowfall. As the oceans warm, more moisture evaporates into the air. Then, when the atmospheric conditions are right for a storm, that increased evaporation results in “heavier and heavier precipitation,” Thoman said. That’s in part why Anchorage saw 41.2 inches of snow last month, capping off its wettest year on record, according to the National Weather Service.

City officials say crews have made progress. But there are challenges. Crews are currently focused on hauling snow from main streets that are near schools, said Kohlhase’s Thursday email. He said he hopes to get every school cleared by the time classes resume on Monday, Jan. 9.

Alaska’s longest and most popular hunting season ended early this year. The Delta Junction bison hunt usually extends from October to March, but the state limited this year’s season to just two weeks, and only 50 animals were taken, because last winter’s heavy snow and ice buildup wiped out nearly a third of the Delta bison herd.

Three weeks after ex-typhoon Merbok hit Western Alaska and breached the Nome-Council Road, Department of Transportation crews and local contractors finished their repairs.

The powerful remnants of Typhoon Merbok pounded Alaska’s western coast on Sept. 17, 2022, pushing homes off their foundations and tearing apart protective berms as water flooded communities. Storms aren’t unusual here, but Merbok built up over unusually warm water. Its waves reached 50 feet over the Bering Sea, and its storm surge sent water levels into communities at near record highs along with near hurricane-force winds.

Just two days after temperatures dipped below -5 degrees Fahrenheit in Hooper Bay, they shot up above freezing, and it started to rain. That caused the water level in the lagoon to rise, and water started to flow through the crack, eroding the lagoon wall.

The ground was completely white in Reykjavík on just 17 days during 2021—the second-lowest number on record. The summer was the warmest on record in many parts of the country and many heat records were broken.

In 2021, the average temperature in Norway was normal, while precipitation was 10 percent below normal. The year is nevertheless marked by great contrasts. The summary of the weather in 2021 was presented at the Meteorological Institute's annual event Climate Status on 5 January. Here you can see video footage of Climate Status (Vimeo)

The city had 9.53 inches of rain last month, surpassed only by the 10.84 inches that fell in July 1915.

Fearing that runoff from the December rains might have carried contamination to Henderson Farm in Haines, the American Bald Eagle Foundation has told its renters they won't be able to farm their plots this year.

More Central Americans have migrated north due to recent storms but haven't been able to enter the U.S. as experts warn climate crises will intensify migration.

Recent storms have battered the Yukon-Kuskokwim Delta coast and dumped multiple feet of snow in some places. Some are saying that this is more snow than

The Department of Civil Protection has raised the level of alert from Uncertain to Dangerous, due to a risk of avalanches. This morning it was found that an avalanche had fallen on the Skarðsdalur Ski area. Nine houses in Siglufjörður will be evacuated.
