Strong winds up to 60 mph prompted National Weather Service (NWS) meteorologists to issue a high wind warning for parts of Montana, North Dakota, and Wyoming on Thursday.
Why It Matters
Although not tropical in nature, the winds are equivalent to the strength of a tropical storm, which ranges between 39 and 73 mph. In most cases, sustained winds across the three states measured at 40 mph, with some gusts reaching 60 mph.
The winds are strong enough to cause damage, power outages, and make travel difficult, prompting the warnings.
NWS meteorologist Molly Gerhardt told Newsweek the high winds are accompanying a cold front moving into the area.
What to Know
In each case, the NWS offices issued the high wind warning in the morning hours. The warnings will remain in place through the evening.
In Montana, northwest winds 35 to 45 mph with gusts up to 60 mph are expected for Sheridan County. The warning went into effect at 9 a.m. local time and will remain in place through 9 p.m.

“High winds may move loose debris, damage property, and cause power bumps,” the NWS office in Glasgow, Montana, said in the warning. “Travel could be difficult, especially for high profile vehicles.”
In North Dakota, the alert warned of northwest winds to 40 mph with gusts to 60 mph. The warning is in place for Divide, Burke, Renville, Williams, Mountrail, Ward, and McLean counties and is in effect until 9 p.m. local time.
In Wyoming, the high wind warning is in effect from 10 a.m. local time through 6 p.m. this evening. It affects northeast Johnson County, with the strongest winds expected to hit between noon and 4 p.m. Northwest winds were expected to be between 30 and 40 mph, with higher gusts.
A wind advisory, in which winds could still be damaging but not as strong as those requiring a high wind warning, is in place across much of North Dakota, South Dakota, and Montana.

A Bismarck, North Dakota, high wind warning said: “The high winds may damage roofs, small outbuildings and signs. Tree branches may be broken. Travel will be difficult, especially for high profile vehicles.”
A Glasgow, Montana, high wind warning said: “Remain in the lower levels of your home during the windstorm, and avoid windows. Watch for falling debris and tree limbs. Use caution if you must drive.”
A Riverton, Wyoming, high wind warning said: “Use caution if you must drive. Secure loose objects outdoors.”
