Take Precautions in Frigid Weather

Palo Alto County is in the midst of an arctic blast, with temperatures in the single digits for a high and double-digit below zero for a low. The frigid temperatures are expected to last until midway through next week, when things will “warm up” to the teens.

The National Weather Service offers this information:

The combination of wind and low temperature in winter can be deadly. The wind chill index helps you determine when dangerous conditions develop that could lead to frostbite or hypothermia. It takes into account heat loss from the human body to its surroundings during cold and windy weather. The calculation utilizes wind speed in miles per hour and temperature in degrees Fahrenheit. For example, a temperature of minus 5 degrees occurring with a 20 mph wind gives a wind chill near minus 30 degrees (see wind chill calculation table below). This means that your body will lose heat at the same rate as it would if the air temperature were minus 30 degrees with no wind. Wind chill values near minus 25 degrees mean that frostbite is possible within 15 minutes.

Frostbite is the freezing of skin and the body tissue just beneath it. It first affects exposed body tissue where blood circulation may be limited such as your fingers, toes, nose and ears. To minimize frostbite, make sure all body parts are well covered. When frostbite starts, feeling is lost in the affected area and the frozen tissue will take on a white or pale appearance. If you suspect you are experiencing frostbite, hold the frostbitten area closely against warm skin to return blood flow and warmth to the affected area.
