70 miles per hour winds are dangerous, and considered severe.
Sudden gusts at that speed can be as if a truck hit something at that speed.
Power outages, shattered glass, downed light and telephone poles, broken street lights, tree limbs being hurled, and swerving vehicles resulting from difficulty in maintaining intended vehicle course, are all possible repercussions of those winds.
In rural and open areas, where there are only a few structures and all are sturdy, witnessing windstorms might not show all that much; in urban and city areas, the effects can be different. It is not recommended to rely on buildings to block or protect oneself from severe winds.

Many places from Great Falls, Mont., to Kansas City, Mo., could be hit with wind gusts between 50 and 70 mph.
Other cities... [that have a strong chance of being impacted] include:
- The core of the strongest winds will pass south and west of Minneapolis.
Gusts as high as

Approaching hurricane force, these winds will likely take down tree limbs and power lines, leading to power outages, property damage and travel concerns. There is a risk of vehicle rollovers in areas where there is a crosswind, especially in the
I-25 corridor."
