Wind
Chill Chart 
To find out what the Wind Chill is where you are, round
your wind speed and the air temperature to the nearest 5. Then find each of
those on the table and that will tell you what the Wind Chill is. A Wind Chill
Warning is issued when the wind chill temperature is forecast to be -25° or
lower. A Wind Chill Advisory is issued when the wind chill temperature is
forecast to be between -10° to -24°.
The blue numbers mean that frostbite will occur in 15
minutes or less.
