Winter weather » Heavy snowfall

Heavy Snow – refers to either the intensity or amount of snow. When used in reference to intensity, heavy snow is that which reduces visibility to less than 5/16 statute mile (about 1/4 mile).

The National Weather Service issues a heavy snow warning if amounts of 6 or more inches are expected in a 12-hour period, or 8 or more inches in a 24-hour period. In areas where this amount of snow is infrequent, a snowfall of 2 or 3 inches would qualify as heavy snow.
