Why Thunder Rumbles. After the snowy winter of in New England, in which a record-setting The most common hazard caused by blowing and drifting snow is quickly reduced visibility while driving. The lowest visibility would occur when falling snow accompanies any blowing and drifting snow, but visibility is still reduced without the falling snow. This may especially be the case when the sun is shining on areas of blowing and drifting snow, reflecting off the white snowflakes and making it even harder to see see the photo from Watertown, New York, under the blowing snow section.

In addition, any pilots trying to take off or land an aircraft may have a hard time doing so if blowing or drifting snow reduces visibility on the runway. Although less common, snow drifts can technically be a fire hazard, in rare cases. This can happen during major lake-effect storms when heavy snow bands dump three or more inches of snow per hour over a given location for several consecutive hours.

In the core of lake bands, winds can be very strong, leading to snow drifts six or more feet tall. If snow drifts grow higher than the windows and doors in your house, you may not be able to exit during an emergency. As the snow continuously gets blown against your home, it can be nearly impossible to get any doors open. A prime example of this is shown in the photo below, after more than 7 feet of snow accumulated locally in the Buffalo Southtowns the week before Thanksgiving When combined with falling snow, blowing and drifting snow can lead to near zero visibility at times.

It is best to stay off the roads when this happens and wait until conditions improve before driving to your destination. Mountain locations are rather susceptible to blowing and drifting snow, especially in the highest elevations of the mountain West.
