The National Weather Service issued wind-chill warnings for Alaska’s northern and western coasts.
Warnings of dangerously cold winds were forecast for a handful of northern areas including the Beaufort Sea coast, the southeastern Brooks Range and the Kobuk and Noatak river valleys. Wind chill was predicted to range from 40 to 60 below zero and the weather service said frostbite could occur on exposed skin in as little as 10 minutes in those conditions.
The weather service issued wind-chill advisories through Friday morning for the Bering and Chukchi sea coasts, including the Seward Peninsula and the Yukon Delta.
