Extreme Weather Conditions in Alaska: A Perfect Storm of Heavy Snow and Avalanche Risks
The U.S. Coast Guard was spotted on video helping to rescue residents of Kipnuk, Alaska, after the remnants of Typhoon Halong caused severe flooding on Oct. 12. The situation has escalated, with extreme winter weather causing large vessels to sink in the Juneau, Alaska, harbor, and communities are making preparations for a possible avalanche.
The City and Borough of Juneau Docks and Harbors Department said the impact of severe weather is seriously impacting the harbor. Three large vessels completely sunk overnight, bringing the storm total to nine vessels that have been lost so far, city officials said.
Consequences of Severe Weather
“Our crews are running around the clock, using every de-watering pump available, and we are now rapidly running out of resources as conditions persist,” Juneau Harbors said on social media. The Alaska Department of Transportation and Public Facilities is conducting avalanche hazard reduction above Thane Road on Thursday due to a high avalanche hazard in the area.
This work is intended to reduce the risk of larger avalanches impacting the area. DOT officials said that if avalanche debris reaches the roadway, an extended closure may be necessary.
Preparations and Warnings
The road will remain closed at the avalanche gates until hazard reduction work is complete and conditions allow for a safe reopening, officials said. If you own a boat, officials ask that you don’t shovel snow onto floats or finger floats, as finger float snow removal is the responsibility of vessel owners.
The type of snow determines how much it weighs, and how much of an impact it could have on homes or vessels. Alaska has been hit with a snowier than normal December, contributing to the overall risks associated with the severe weather.
Record-Breaking Snowfall
During a typical December, Juneau sees between 40 and 50 inches of snow. However, in December 2025, the snow total surpassed records, reaching a whopping 82 inches. The previous snow total was 54.7 inches, set back in 1964.
The Juneau Docks and Harbors Department is working to bring back seasonal summer staff and has created short-term emergency positions to help with snow removal. Anyone who sees a vessel at risk of sinking in any City and Borough of Juneau harbor is asked to contact the Harbor Office at 907-586-5255.
