Update — November 8, 2026, 1:10 p.m. Central:

The National Weather Service’s 11:42 a.m. Mountain Standard Time Sunday update now forecasts west winds of 35–55 mph with gusts up to 90 mph in the mountain-front warning area, while retaining isolated gusts around 100 mph near the immediate eastern slopes of the Rocky Mountain Front. The 90-mph forecast replaces the earlier 95-mph figure below; these are forecast speeds, not confirmed observations.

The warning remains in effect until 8 p.m. MST Sunday for the East Glacier Park Region, northern and southern High Plains, and eastern Glacier, western Toole and central Pondera areas. Forecasters warn of possible tree and power-line damage, isolated outages and difficult travel, especially for high-profile vehicles and vehicles towing trailers.

A separate warning across other north-central Montana zones now calls for west winds of 25–40 mph, with gusts up to 65 mph, through the same 8 p.m. deadline. It includes Hill and northern Blaine counties, the Bears Paw Mountains and southern Blaine, eastern Toole and Liberty, eastern Pondera and Teton, western and central Chouteau, Cascade County below 5,000 feet, and Judith Basin County and Judith Gap.

The agency urges people to secure loose objects. The warnings describe potential impacts rather than confirmed damage or outages.

Update — November 8, 2026, 1:01 a.m. Central:

The National Weather Service’s latest mountain-front warning forecasts west winds of 35 to 55 mph with gusts up to 95 mph and isolated gusts around 100 mph on Sunday, November 8. This raises the localized maximum from the earlier forecast preserved below.

The warning covers the East Glacier Park Region, northern and southern High Plains, and eastern Glacier, western Toole and central Pondera areas from 5 a.m. to 8 p.m. Mountain Standard Time Sunday.

The Great Falls office issued the bulletin at 10:21 p.m. MST Saturday. These are forecast wind speeds, not measured gusts or confirmed reports of damage. Separate areas added to the warning face the lower 65-mph gust forecast described in the previous update.

Update — November 8, 2026, 12:05 a.m. Central:

The National Weather Service expanded Sunday’s high-wind warning across additional parts of north-central Montana in a bulletin issued at 10:21 p.m. Mountain Standard Time Saturday, November 7.

The added areas include northern Blaine County, the Bears Paw Mountains and southern Blaine, eastern Pondera and eastern Teton, and western and central Chouteau County. Cascade County below 5,000 feet, eastern Toole and Liberty, Hill County, and Judith Basin County and Judith Gap are also covered.

These zones face west winds of 30 to 40 mph, with gusts up to 65 mph, from 8 a.m. to 8 p.m. MST Sunday, November 8. The earlier mountain-front warning below carries a different period and stronger localized gust forecast.

Forecasters warn that winds could knock down trees and power lines and make travel difficult, particularly for high-profile vehicles. The forecast of widespread outages is a warning about potential impacts, not a report of outages already occurring.

Update — November 7, 2026, 12:59 p.m. Central:

A revised National Weather Service warning now begins at 5 a.m. Mountain Standard Time Sunday, November 8, four hours earlier than previously reported, and continues until 8 p.m.

The Great Falls office’s 11 a.m. MST Saturday bulletin forecasts west winds of 35 to 55 mph with gusts up to 85 mph across the warned zones. It adds that isolated gusts up to 90 mph are expected along the immediate eastern slopes of the Northern Rocky Mountain Front.

The warning covers the East Glacier Park Region, northern and southern High Plains, and eastern Glacier, western Toole and central Pondera areas. The 90-mph figure is a localized forecast, not a statewide wind speed or a Saturday observation.

The agency continues to warn of falling trees and power lines, widespread outages and difficult travel, particularly for high-profile vehicles. It urges people to secure loose objects.

Earlier Reporting — November 7 Morning Warning:

The National Weather Service issued a high wind warning Saturday for parts of north-central Montana, forecasting west winds of 35 to 50 mph with gusts reaching 85 mph on Sunday, November 8.

The warning period runs from 9 a.m. to 8 p.m. Mountain Standard Time Sunday. The Great Falls office issued the bulletin at 7:37 a.m. MST November 7; the strongest conditions described are a forecast for Sunday, rather than observations of widespread damage Saturday.

The affected forecast zones include the East Glacier Park Region, the northern and southern High Plains, and eastern Glacier, western Toole and central Pondera areas.

Forecasters warn that damaging winds could bring down trees and power lines. The bulletin says widespread power outages are expected and that travel will be difficult, particularly for high-profile vehicles.

The weather service urges people to secure loose objects that could be blown around or damaged. The warning applies to the identified forecast zones, rather than all of Montana, and the maximum gust forecast does not mean every location will record 85 mph.
