The National Weather Service along with the Nebraska Emergency
Management Agency and the Iowa Homeland Security and Emergency
Management Division have declared Thursday, November 9th as
Winter Weather Awareness Day in Nebraska and Iowa.

Wednesday: Wind Chill

Wind chill is the serious and potentially fatal cooling effect of
combined wind and cold on the human body. The National Weather
Service issues wind chill warnings for wind chill values of 30
below or lower and wind chill advisories for wind chill values of
20 to 29 below.

For example, if the outside temperature is zero and the wind speed
is 25 miles per hour, then the wind chill is 24 below. If skin is
exposed to these conditions, frostbite will occur in about 30
minutes. If we decrease the air temperature to 10 degrees below
zero, then the wind chill becomes 37 below. The onset of frostbite
to exposed skin then decreases to 10 minutes.

Frostbite is damage to body tissue caused by that tissue being
frozen. Frostbite causes a loss of feeling and a white appearance
of the skin. Seek medical help immediately. If medical help is not
available, slowly warm the affected areas.

Avoid overexertion. The stress to the heart from cold temperatures
and hard labor from such things as shoveling heavy snow, pushing a
car, or walking in deep snow could cause a heart attack.

Hypothermia is the lowering of the body temperature due to
exposure to the cold. Symptoms are uncontrollable shivering,
memory loss, disorientation, slurred speech, and apparent
exhaustion. If the body temperature has fallen below 95 degrees,
seek medical help immediately. If medical help is not available,
begin warming the person slowly. Warm the body core first. Make
sure the person is dry and wrap them in a warm blanket covering
the neck and head. Do not give the person alcohol, drugs, or
coffee, or any hot beverage or food. Warm broth is better. Do not
warm the arms and legs first. This drives the cold blood toward
the heart and could cause death.
