US: Adverse winter weather forecast across most of Alaska through at least early March 28 /update 1
Severe winter weather forecast across most of Alaska, US, into early March 28. Transport disruptions likely; power outages possible.
Event
Adverse winter weather is forecast across most of Alaska into at least early March 28. The heavy snow and accompanying strong winds will likely lead to hazardous driving conditions due to icy roads as well as reduced visibility due to blowing snow. As of late March 26, the National Weather Service has issued the following warnings, advisories, and watches for Alaska:
Winter Storm Warning: northeastern and southeastern Brooks Range, Central Interior, eastern Norton Sound, Nulato Hills, and Yukon Delta, as well as upper Kobuk, Koyukuk, Noatak, and lower and middle Yukon valleys.
Winter Storm Watch: northern Arctic Coast, central Beaufort Sea Coast, and Denali, as well as lower Kobuk, upper Kuskokwim, Noatak, and middle Tanana valleys.
Wind Advisory: eastern Alaska Range.
Officials may issue new alerts or update/rescind existing advisories as weather conditions change over the coming hours and days.
Hazardous Conditions
Significant snow accumulations are forecast in some affected areas. In addition to the heavy snowfall, strong wind gusts will likely lead to periods of blowing and drifting snow. Blizzard conditions and sporadic power outages are possible throughout affected areas.
Transport
The winter weather may cause ground and air transport disruptions across parts of Alaska over the coming days. Traffic and commercial trucking delays are likely along regional highways; dangerous and challenging driving conditions are also likely on secondary and rural roads in the affected areas as maintenance crews prioritize clearing major routes. Flight delays and cancellations could occur due to ground stops and deicing operations at regional airports.
Advice
Monitor local media for updated weather information. Verify road conditions before driving in areas where heavy snowfall or flooding is forecast or reported. Allow extra time to reach destinations in these areas and carry an emergency kit and warm clothes if driving is necessary, especially on secondary or rural routes that could become impassable. Plan accordingly for delivery delays if routing shipments by truck through affected areas. Confirm flights. Charge battery-powered devices in the case of prolonged electricity outages.
