Wind Chill Chart Lets You Check Safety Before Going Out
This has been one of the coldest winters ever, with record and near-record cold and high winds combining to make going outdoors very, very dangerous. Strong winds and low temperatures mean low wind chills, and low wind chills make frostbite and deadly hypothermia a real possibility.
Depending on your math skills, computing the wind chill can be pretty complicated. Fortunately, the National Weather Service has a handy chart that does the calculations for you. The chart also includes a frostbite indicator, showing the where temperature, wind speed and exposure time will result in frostbite after 30, 10 or 5 minutes of exposure.
For example, a temperature of 0°F and a wind speed of 15 mph will produce a wind chill temperature of -19°F. At that point, skin can freeze in 30 minutes.
It’s worth the few extra seconds it takes to check the wind chill before going out.
