  1. Temperatures with a low of 40 degrees or lower with a probability of rain of at least 5%.
  2. Cold Watch or Cold Advisory issued by the National Weather Service endanger lives of those living outside.

Hypothermia is a medical emergency that happens when your body loses heat faster than it can produce heat, causing a dangerously low body temperature. Normal body temperature is about 98.6 F, and hypothermia occurs when your body temperature drops below 95 F.

People who are 65 and older or very young children are at a higher risk of hypothermia. Alcohol, drug use, and medications can also increase the risk of hypothermia. Left untreated, hypothermia limits your nervous system from working correctly. It can cause a complete failure of your heart, respiratory system, and it can even be fatal.

Symptoms of hypothermia are:

  • Confusion
  • Dizziness
  • Exhaustion
  • Severe shivering
  • Clumsiness and lack of coordination
  • Slurred speech or mumbling
  • Drowsiness or very low energy
  • Weak pulse
  • Slow, shallow breathing
  • Progressive loss of consciousness

Seek medical attention if you experience these symptoms.​​
