🚨 EXTREME FIRE DANGER & HIGH WIND WARNING TODAY 🚨

Oliver County and surrounding areas are under EXTREME fire danger conditions today. With dry conditions and strong winds, even the smallest spark can turn into a fast-moving wildfire in seconds.

🔥 PLEASE DO NOT BURN TODAY 🔥
This includes:
• Garbage burning
• Brush piles
• Campfires
• Fire pits
• Burning barrels
• Welding/grinding in dry grass areas
• Anything that could create a spark

A cigarette tossed from a vehicle, a chain dragging on the highway, or one spark from equipment is all it takes.

⚠️ Everyone is asked to stay alert today.
If you see smoke or fire — CALL IT IN IMMEDIATELY. Quick reporting can save homes, land, livestock, and lives.

🏡 Rural Residents:
It is a good idea to water the grass and areas around your home, buildings, propane tanks, and shelterbelts to help keep them green and slow the spread of fire if one starts nearby.

🚜 Farmers & Ranchers:
If you have portable water tanks, trailers, discs, tractors, or other equipment that could help slow the spread of a fire — and are willing to assist in an emergency — please reach out on this page or contact Chief Bryan Bradley directly. Having local resources ready can make a huge difference during fast-moving grass fires.

Please use caution today and help protect our communities, firefighters, and neighbors. Stay safe and stay aware. 🚒

12/17/2025

Upcoming weather for the evening into tomorrow!
Be weather aware!

Very strong winds tonight (55-75 mph gusts) combined with falling snow will produce near-blizzard to blizzard conditions across northern and eastern parts of the region, and a shorter-duration period of dangerous whiteout conditions (snow squalls) in the west and south. The worst conditions are expected from 9pm Wed. (west) through noon Thu. (east).
An important message from the NWS: "We cannot overstate the danger of being caught on rural highways in snow squalls, as visibility can go from 'as far as the eye can see' to zero in a matter of seconds. The highest snow squall potential is across western and south central North Dakota late this evening through tonight. This includes Highway 85 from Williston to South Dakota, and Interstate 94 from Montana to Bismarck. It is crucial that travelers in this part of the state remain weather aware this evening and tonight, and strongly consider altering their travel plans."
The near-blizzard to blizzard conditions elsewhere will likely impact the Thursday morning commute and could result in delays and possibly cancellations due to very difficult travel.
