  • Wind chills to −57°C (−70°F) as Extreme Cold and Blizzard Warnings continue across Alaska

    ByRishav Kothari

    Extreme Cold Warnings and Blizzard Warnings remain in effect across northern and western Alaska on February 11, 2026, with the National Weather Service forecasting wind chills as low as −57°C (−70°F) along the Arctic Coast and Brooks Range and wind gusts up to 105 km/h (65 mph) on St. Lawrence Island. Air temperatures near −46°C (−50°F) combined with increasing winds are expected to intensify frostbite risk across the North Slope, while snowfall of 7–15 cm (3–6 inches) and visibility reductions to 400 m (0.25 miles) or less are forecast in parts of western Alaska through early February 12.

  • Pavlof volcano alert raised after rise in long-period earthquakes, Alaska
