What Triggers a Cold Weather Activation?
Cold weather can create a higher risk of car accidents, hypothermia, frostbite, carbon monoxide poisoning, and heart attacks from overexertion. In certain areas, winter storms can bring extreme cold, freezing rain, snow, ice, and high winds. Santa Clara County has experienced its fair share of extreme cold weather and has opened warming centers throughout the County to provide community members with a warm and safe space to take shelter.
An Cold Weather Activation is triggered when:
- Overnight low of 40° F or lower with a probability of rain of at least 5%;
- Overnight low of 45° F or lower with a 50% or higher probability of rain;
- Persistent rainfall expected for two or more days that would create life-threatening conditions for those living in or along affected areas; or
- Overnight low of 35° F or lower for two or more days that would endanger the lives of people living in places not meant for human habitation (outside or in vehicles).
When weather conditions are within range of the triggers, a member of the CRT will contact the National Weather Service to receive a detailed and current forecast. If conditions warrant, the CRT member will contact the OEM Duty Officer.
For detailed process and procedures for declaring an Cold Weather Activation, you may read the Inclement Weather Annex . You may also find this functional annex on our For Partners page under Emergency Operations Annex.

Cold Weather Safety Tips
- Avoid being outside during the coldest part of the day, or for extended periods of time in extreme cold weather
- Dress in layers
- Wear a hat, scarf and gloves/mittens
- Wear waterproof, insulated boots to avoid hypothermia or frostbite
- Get out of wet clothes as soon as possible
- Stay hydrated
- Avoid excessive consumption of alcohol if you will be staying 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:
- 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.
