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. 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.
