US, Canada: Adverse winter weather forecast across parts of southeastern Alaska and far western Canada through at least March 17
Severe winter weather forecast across parts of southeastern Alaska and western Canada through March 17. Hazardous travel conditions likely.
Event
Adverse winter weather is forecast across parts of southeastern Alaska and far western Canada through at least March 17. A low-pressure system over the Gulf of Alaska is forecast to bring a mixture of snowfall and heavy rainfall across the northern Alaskan Panhandle and into far western Canada over the coming days. Flooding is possible in areas where heavy rainfall over frozen ground causes excessive runoff. Snowfall accumulations of 15-35 cm (6-14 inches) are possible across parts of the affected area. Hazardous travel conditions are likely due to icy roads and reduced visibility caused by blowing snow.
Government Advisories
As of early March 15, the US National Weather Service has issued winter storm warnings for Haines Borough and Kulkwan and the Municipality of Skagway. A winter storm watch has been issued for the City and Borough of Yakutat and a winter weather advisory for the City and Borough of Juneau. A special weather statement for heavy rainfall on top of fresh snow and ice has been issued across northern and central parts of the Alaskan Panhandle.
Environment Canada has issued winter storm watches for Haines Road and South Klondike Highway in British Columbia and Haines Junction and Whitehorse in Yukon.
Officials may issue new alerts or update/rescind existing advisories as weather conditions change over the coming hours and days.
Hazardous Conditions
Snow accumulations are likely across the affected area. Lesser snowfall totals are possible where sleet and freezing rain mix with snow. In addition to the heavy snow, strong wind gusts will probably lead to periods of blowing and drifting snow. Blizzard conditions are possible. Sporadic power outages are possible throughout the affected area.
Transport
The winter weather may cause ground and air transport disruptions across parts of the affected area 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.
