Winter Storm Warning
Statement as of 03:17 PM EST die 07o December, anno 2013
... Winter Storm Warning in effect from 7 am Sunday to 7 am EST
The National Weather Service in Wakefield has issued a Winter
Storm Warning for sleet and freezing rain... which is in effect
from 7 am Sunday to 7 am EST Monday. The Winter Storm Watch is no
longer in effect.
* Areas affected: western central Virginia Piedmont... mainly
across Louisa... goochalnd... Cumberland and Farmville.
* Accumulations: a quarter inch or more of ice accumulation is
expected. Up one inch of a snow and sleet mix is possible.
* Timing: a mix of snow... sleet... and freezing rain is expected
to begin early Sunday morning... then change to all freezing
rain by Sunday afternoon. Freezing rain is then expected to
persist into Sunday night.
* Temperatures: 28 to 32 degrees.

roads and icy conditions Sunday into Sunday night. Power outages
are also possible due to falling limbs from the weight of the
A Winter Storm Warning for heavy snow means severe winter weather
conditions are expected. Significant amounts of snow are forecast
that will make travel dangerous.

winter preparedness week in Virginia
December 1-7, 2013
Governor bob mcdonnell has declared the week December 1 to 7, 2013
as winter preparedness week in Virginia. The National Weather Service
/NWS/ offices serving Virginia... in cooperation with the Virginia
department of emergency management... will send public information
statements over the NOAA weather wire service each day through Saturday
at approximately 11 am and 3 PM EST. These statements will focus on
different aspects of winter weather in the mid Atlantic region... and
preparedness actions the public should take for the upcoming winter
Today's topic - cold weather preparedness and wind chill
Cold temperatures are just a fact of winter. Cold outbreaks occur
several times each winter across the mid Atlantic region. With these
cold temperatures comes an increase in the number of house fires.
According to the National fire protection association... a house fire is
reported to a Fire Department in the United States every one and a half
minutes, and someone dies in a house fire every two and a half hours.
Nearly two of every three home heating fires in the U.S. Are attributed
to space heating equipment. All types of common space heating equipment
are involved in home fires - electric heaters... kerosene heaters... wood
stoves... fireplaces... and gas heaters. Common causes of space heating
home fires are lack of regular cleaning of chimneys and Connectors...
placing space heaters too close to combustibles... and fueling errors
involving liquid or gas fueled heating equipment.
The Red Cross recommends taking the following preventive measures to
help minimize the chance and effects of fire.
1) be careful with candles. Colder temperatures usually result in more
burning of candles during the winter season than any other time of year.
Winter storms and power outages further increases the use of candles in
the home. Keep candles away from combustible materials. Never leave
children unattended in a room with lit candles. Keep candles, matches
and lighters out of The Reach of children.
2) inspect fireplaces and wood stoves. Have your chimney connections
and flues inspected by a professional and cleaned if necessary prior to
the start of every heating season.
3) use a sturdy screen or door in front of your fireplace when burning
4) burn only wood. Never burn paper, including discarded gift wrap, or
5) do not hang Holiday decorations from... or on... your fireplace... if
you plan to use it as a heat source.
6) check smoke detectors. Make sure detectors are working properly and
that new batteries are installed.
7) be aware of overloaded electrical outlets - don't overload your
electrical outlets... and avoid laying extension cords across walkways.
8) have one or more working fire extinguishers in your home. Most fire
departments will provide training on how to use fire extinguishers.
Many people fall victim to fires in their homes during the winter. This
fact means that everyone should have a fire extinguisher, test fire
detectors in their home and replace any broken detectors and dead
**************************Wind chill index***************************
The wind chill index is winter's version of the summertime heat index.
The heat index attempts to assess the combined effects of hot
temperatures and high relative humidity on the human body's ability to
cool itself. The wind chill index attempts to measure the combined
effect of wind and cold temperatures on the body's ability to retain
heat, and avoid hypothermia. Recent scientific data indicated that,
prior to 2001, wind chill was being inaccurately computed for 2
reasons. First, the wind speed used in the computation was measured
at 33 feet, and was not representative of the wind at "head" height.
Second, heat Transfer theory had not been accurately incorporated
into the previous computations.
On November 1 2001, the National Weather Service implemented a new wind
chill temperature index. The latest advances in science, technology
and computer modeling have resulted in a significantly improved wind
chill index. The wind chill index provides a more accurate,
understandable and useful formula for calculating the potential danger
from the combination of wind and cold temperatures.
In most instances, for the reasons mentioned above, wind chill
temperature values are warmer than the wind chill temperatures found
on pre-2001 wind chill charts. As a result of the new computations, the
threshold for wind chill advisories issued for Virginia citizens is now
5 degrees below zero, and the wind chill warning threshold is 20 degrees
below zero. In North Carolina, the thresholds are zero and 15 degrees
below zero respectively. At 20 degrees below zero, frostbite on exposed
skin can occur in 30 minutes or less.
The wind chill temperature can be routinely found, on an event driven
basis, in regional weather roundups /rwrakq in Virginia... rwrrah in
