Winter Storm Frequently Asked Questions
1.
What is wind chill?
Wind chill is the
perceived temperature resulting from the effect of wind, in combination
with cold air, which increases the rate of heat loss from the human
body.
2. What is frostbite
and what can you do to treat it?
Frostbite is damage
to body tissue caused by that tissue being frozen. Frostbite causes
a loss of feeling and a white or pale appearance in extremities,
such as fingers, toes, ear lobes, or the tip of the nose. Frostbite
varies in severity from frostnip to deep frostbite, depending on
the length of exposure, temperature to which the skin is exposed
and wind speed. For frostnip, place firm, steady pressure from a
warm hand against the area. Also, blow on the surface holding the
frostnipped area against the body. Do not rub the area, apply snow
or plunge it into very hot or cold water. Victims of severe frostbite
must receive prompt medical attention.
3. What is hypothermia
and what are the warning signs?
Hypothermia occurs
when the body temperature drops to 95 degrees F. or lower. It can
develop whenever body heat loss exceeds heat gain. Hypothermia is
not exclusive to winter. It can occur during the wind and rain of
spring and summer. Hypothermia is often mistaken for fatigue, irritability,
or dehydration and may include some of these signs: abnormal decision
making; improper response to cold; apathy, lethargy; decreased cooperation;
slurred speech; disorientation; shivering; stumbling; and stiffness
progressing to inability to move.
4. How do you treat
hypothermia?
Mild to moderate
hypothermia (body temperature greater than 90 degrees F., conscious,
shivering, able to walk)
- Prevent
further heat loss. Dry, remove from cold and insulate.
- Rewarm
by warming the body core first. Rehydrate with warm broth.
- Seek medical
attention.
- Severe hypothermia
(body temperature less than 90 degree F., unconscious, not shivering).
- Prevent
further heat loss.
- Seek immediate
medical attention.
5. What are the
various winter weather warnings and advisories?
- A
winter storm watch indicates that severe winter weather conditions
may affect
your area.
- A
winter storm warning indicates that severe winter conditions are
imminent.
- A
winter storm warning for heavy snow indicates snowfalls of at least
6 inches
in 12 hours or 8 inches in a 24-hour period are expected. In the
Upper Peninsula , it indicates 8 or more inches in 12 hours and 10
or more inches in a 24-hour period.
- Blizzard
warnings are issued when sustained wind speeds or frequent gusts
of at least 35 miles per hour are accompanied by considerable falling
and/or blowing snow. Visibility is greatly reduced during a blizzard.
- Snow
advisories are issued when snowfalls of 4 to 5 inches are expected
in a 12-hour
period for the average of the forecast range. In the Upper Peninsula
, it would result when 4 to 7 inches of snow are anticipated in that
same time period.
