Iowa Homeland Security and Emergency Management Department and the National Weather Service have declared November 7, 2013 as Winter Weather Awareness Day in Iowa. Winter weather is a seasonal hazard in Iowa which can lead to life-threatening conditions. Understanding winter weather hazards and how to prepare for them can save lives.
On November 7, 2013 the National Weather Service in Des Moines will issue a Public Information Statement concerning winter weather safety. Media interviews are also encouraged to increase awareness about this weather threat. In addition, we will be hosting a social media open house on Facebook and Twitter, which will allow social media users to ask meteorologist at the National Weather Service questions related to winter weather and winter weather preparedness.

The wind chill temperature is not the actual air temperature, it is a “feels like” temperature when one factors in cold temperatures AND wind speeds. Increasing winds will accelerate the amount of heat lost by the body via exposed skin, driving down the body temperature. Animals are also affected by wind chill.
The wind chill chart below was developed based on joint U.S.-Canadian research. The chart includes a frostbite indicator, showing the points where temperature, wind speed and exposure time will produce frostbite on humans. Each shaded area shows how long a person can be exposed before frostbite develops.
Note: Wind chill temperature is only defined for temperatures at or below 50°F and wind speeds above 3 mph. Bright sunshine may increase the wind chill temperature by 10 to 18°F.
