A Winter Weather Advisory for snow means that periods of snow are
expected or occurring... but accumulations are expected to be
light. Driving and walking may be difficult on untreated roadways
and sidewalks. Be prepared for snow covered roads and limited
visibilities. If you must travel... slow down and allow extra time
to reach your destination.
A Wind Chill Advisory means that cold air and strong winds will
combine to generate very low wind chills. These conditions can
result in frost bite and lead to hypothermia or even death if
precautions are not taken. Those venturing outdoors should dress
warmly... making sure all exposed skin is covered.
