Great Falls, Montana – Dangerous cold conditions continue across north-central Montana Sunday morning, prompting an Extreme Cold Warning as wind chills plunge well below zero and pose serious health risks.
According to the National Weather Service in Great Falls, wind chills as low as 36 degrees below zero are expected through 11 a.m. MST in parts of Hill County, Northern Blaine County, Southern Blaine County, and the Bears Paw Mountains.
Communities included in the warning area are Havre, Chinook, Harlem, Zurich, Rocky Boy, Fort Belknap, and Hogeland. The warning remains in effect for both plains and higher-elevation locations, where exposure risks are heightened by persistent cold and wind.
The National Weather Service warns that frostbite can occur on exposed skin in as little as 10 minutes under these conditions. Prolonged exposure may also increase the risk of hypothermia, especially for individuals without adequate winter clothing or shelter.
Residents are urged to limit time outdoors when possible. Those who must go outside are advised to dress in multiple layers, including a hat, face covering, insulated gloves, and wind-resistant outerwear. Pets should be kept indoors, and vulnerable populations should be checked on during the warning period.
Extreme cold events are especially hazardous during early morning hours when temperatures and wind chills are typically at their lowest. The warning is expected to expire later this morning as conditions gradually improve.
For students, workers, and early commuters, the warning may affect outdoor activities, school transportation, and morning travel routines across the region.
Additional weather updates and any changes to the warning will be issued by the National Weather Service as conditions evolve.
