Winds of this strength due to downslope winds off terrain have been known to shatter windows and sandblast paint from cars.
This process cause thunderstorm formation (and decay) to last for several hours or even over multiple days. Cumulonimbus clouds can also occur as dangerous winter storms called " thundersnow " which are associated with particularly intense snowfall rates and with blizzard conditions when accompanied by strong winds that further reduce visibility .
Clouds and new thunderstorms also develop along the outflow's leading edge. This makes it possible to locate the outflow boundary when using precipitation mode on a weather radar. Also, it makes outflow boundaries findable within visible satellite imagery as a thin line of cumuliform clouds which is known as an arcus , or arc, cloud.
