Winter Weather
Advisories: Issued
for accumulations of snow, freezing rain, freezing drizzle, and sleet
which will cause significant inconveniences and, if caution is not
exercised, could lead to life-threatening situations.
Dense Fog Advisory:
Issued
when fog will reduce visibility to ¼ mile or less over a widespread area.
Snow Flurries:
Light snow falling for short durations. No accumulation or light dusting
is all that is expected.
Snow Showers:
Snow falling at varying intensities for brief periods of time. Some
accumulation is possible.
Snow Squalls:
Brief, intense snow showers accompanied by strong, gusty winds.
Accumulation may be significant. Snow squalls are best known in the Great
Lakes region.
Blowing Snow:
Wind-driven snow that reduces visibility and causes significant drifting.
Blowing snow may be snow that is falling and/or loose snow on the ground
picked up by the wind.
Sleet: Rain
drops that freeze into ice pellets before reaching the ground. Sleet
usually bounces when hitting a surface and does not stick to objects.
However, it can accumulate like snow and cause a hazard to motorists.
Freezing Rain:
Rain that falls onto a surface with a temperature below freezing. This
causes it to freeze to surfaces, such as trees, cars, and roads, forming a
coating or glaze of ice. Even small accumulations of ice can cause a
significant hazard.
