...This Week is Winter Weather Awareness Week in South Carolina...

To begin with we will look at some of the National Weather Service
product definitions:

Winter Storm Watch: An announcement for specific areas that winter
weather may develop during the next 24 to 48 hours and produce
significant accumulations of freezing rain, sleet or snow.

Winter Storm Warning: An announcement for accumulations of at least
1 to 3 inches of snow or sleet in 12 hours, or 2 to 4 inches of snow
or sleet in 24 hours. Winter Storm Warnings will also be issued when
1/4 inch or more of freezing rain is expected to develop in the area
in 24 hours or less.

Blizzard Warning: Issued when there is considerable falling or
blowing snow reducing visibilities to 1/4 mile or less and the winds
are sustained or gusting to at least 35 mph. These conditions are
expected to occur for at least 3 hours.

Winter Weather Advisory: An announcement for average accumulations
of around 1/2 to an inch of snow or sleet, or less than a 1/4 inch
of freezing rain. These conditions are expected to develop in the
area in 24 hours or less.

The remainder of the week will be spent discussing the various
aspects of winter weather.
