DECEMBER 3-9, 2017...

This week has been declared winter weather preparedness week in
North Carolina.  All week long the National Weather Service will
be issuing informative messages to help you prepare for winter

Outlook for this winter:
Forecasters at NOAA`s Climate Prediction Center issued the U.S.
Winter Outlook in late October, saying that La Nina is expected to
influence winter conditions this year.  La Nina favors drier,
warmer winters in North Carolina.  This climate outlook provides
the most likely outcome for the upcoming winter season; however,
regardless of the outlook, there is always some chance for extreme
winter weather.  With that in mind, everyone should use this week
to prepare for the upcoming winter months and the possibility of
winter storms.

Winter Products:
Winter Storm Watches and Warnings are issued by the NWS for
potentially life-threatening conditions.  Winter Storm Watches are
issued when at least 3 inches of snow, and/or a 1/4 inch or more
of ice accumulation is expected in a 12 to 24 hour period.  They
are typically issued within 24 to 48 hours of the storm.  Winter
Storm Warnings are issued when at least 3 inches of snow or ice
accumulations of 1/4 inch or more are likely within 24 hours.  A
Winter Weather Advisory is issued when 1 to 3 inches of snow or
ice accumulations of less than 1/4 inch are likely within 24
hours.  A Blizzard Warning is issued when strong winds combine
with falling and/or blowing snow to reduce visibility to one
quarter mile or less for at least 3 hours.  Finally, a Wind Chill
Warning is issued when wind chill temperatures are forecast to
reach 15 degrees below zero or colder.

Winter Terminology:
Freezing Rain is rain that falls and freezes to a cold surface
such as a road or tree, causing a glaze of ice to form.  Freezing
rain forms when rain falls through a warm layer above the ground
then freezes upon reaching the ground when the surface air and
ground-level objects are below freezing.  Freezing rain or "ice
storms" can bring down trees and power lines, and severely hamper
travel.  Sleet is melted snow that has re-frozen into ice pellets
prior to reaching the ground. Sleet forms in a similar manner to
freezing rain.  However, the layer of cold air near the ground is
thick enough to allow the rain drops to re-freeze before reaching
the ground.  Sleet will bounce when it strikes a hard surface.
Sleet can accumulate like snow and make a road slick, but it is
not as hazardous as freezing rain.  The term flurries refer to
very light snow or snow that occurs for a short time period only
causing a light dusting at best.  Finally, the wind chill
temperature is the "feel-like" temperature denoting the combined
effect of wind and temperature on people and animals.  Wind chill
is based on the rate of heat loss from exposed skin.  Wearing
layers of clothing will help retain your body heat and combat wind
chill.  Once wind chill temperatures drop below -20 degrees
Fahrenheit, exposed flesh can freeze in 30 minutes or less,
causing frost bite.

Winter storms are deceptive killers because most deaths are
indirectly related to the storm.  Examples are traffic accidents
due to icy roads, heart attacks while shoveling snow, fires, and
carbon monoxide poisoning.  The National Weather Service issues
advisories, watches, and warnings to help you prepare for upcoming
winter weather and take appropriate action to protect yourself and
your property.
