Deciphering the Hierarchy of Winter Alerts
A winter alert is not a single, universal notification but rather a family of terms used by weather authorities to communicate the severity and timing of upcoming winter conditions. Understanding the distinctions between these terms is the first step toward effective preparation.
Winter Storm Watch: Be Prepared
- A watch indicates that conditions are favorable for a significant winter storm.
- It is typically issued 12 to 48 hours in advance, giving you time to prepare your home and vehicle and gather supplies.
- A watch means a winter storm is possible, but not certain.
Winter Weather Advisory: Be Aware
- An advisory is issued for winter weather events that are less severe than a warning but are still hazardous.
- Conditions like light snow, freezing rain, or sleet are expected to cause significant inconvenience and could be hazardous if caution is not exercised.
- An advisory means to proceed with caution and be prepared for changing road conditions.
Winter Storm Warning: Take Action!
- A warning means a dangerous winter storm is happening or is imminent.
- This is a threat to life and property, indicating travel will become very difficult or impossible.
- Immediate action is required to ensure your safety.
Other Specific Warnings
-
Blizzard Warning
Issued for severe winter storms with sustained winds of 35 mph or higher, heavy snow, and low visibility for at least three hours.
-
Ice Storm Warning
Indicates that ice accumulation of at least a quarter-inch is expected, which can cause significant damage to trees and power lines.
-
Wind Chill Warning
This is issued for dangerously low wind chill values that can cause frostbite in a short period.
Major Health Risks During Cold Weather
Extreme cold is more than just uncomfortable; it poses several serious health risks that require a proactive approach.
- Hypothermia: A dangerous drop in body temperature. Early signs include shivering, exhaustion, and confusion.
- Frostbite: An injury caused by freezing, most often affecting extremities like fingers, toes, ears, and nose. Skin may appear waxy, pale, or white.
- Carbon Monoxide Poisoning: This colorless, odorless gas can build up from improper use of indoor fuel-burning appliances. It can cause headaches, dizziness, and death.
- Cardiovascular Strain: Shoveling heavy snow or overexerting yourself in the cold can put a significant strain on the heart, leading to heart attacks, especially in older adults.
- Slips and Falls: Icy conditions dramatically increase the risk of serious injuries from falls.
Your Winter Emergency Action Plan
Preparation is the key to minimizing risk during a winter alert. A comprehensive plan should cover both your home and vehicle.
Home Preparedness
- Winterize your home: Insulate walls, caulk leaks, and weather-strip doors and windows to conserve heat.
- Assemble an emergency kit: Include at least a three-day supply of water and non-perishable food, flashlights with extra batteries, a first-aid kit, and essential medications.
- Ensure alternative heat and power: Have a backup heat source like a fireplace, and keep fuel stored safely. Have a battery-powered radio for updates.
- Install safety detectors: Make sure you have working smoke alarms and, crucially, carbon monoxide detectors with battery backups.
Vehicle Preparedness
- Get a vehicle checkup: Ensure your mechanic inspects the battery, ignition, exhaust, and brakes.
- Keep the gas tank full: This helps prevent the fuel line from freezing and provides heat if you get stranded.
- Create a car emergency kit: Include a first-aid kit, blankets, a flashlight, jumper cables, and sand or kitty litter for traction.
Driving Safely in Winter Weather
Driving conditions deteriorate rapidly during winter alerts. The safest option is to stay off the road, but if you must travel:
- Reduce your speed and increase your following distance.
- Do not use cruise control on slippery surfaces.
- Be wary of black ice, especially on bridges and overpasses.
- If you skid, take your foot off the gas and steer in the direction of the skid.
- Never pass a snowplow.
Protecting Vulnerable Populations
Certain groups are more susceptible to cold-weather dangers and require special attention.
- Older Adults: Aging can reduce the body's ability to regulate temperature. Check on elderly neighbors to ensure they have adequate heating, food, and medication.
- Young Children: Infants and young children lose heat more quickly than adults. They should be dressed in warm layers and monitored closely when outdoors.
- Individuals with Disabilities: People with limited mobility or certain health conditions may need extra assistance with transportation or accessing resources.
- Unsheltered Individuals: People experiencing homelessness are at extreme risk of hypothermia and frostbite. Provide resources or inform local aid organizations.
Comparing Essential Kits for Winter Alerts

Warmth | Blankets, sleeping bags | Blankets, extra clothes |
Traction | No | Sand or kitty litter |
Signaling | Battery radio | Brightly colored cloth, flares |
Tools | Can opener, basic tools | Jumper cables, small shovel |
Safety | Carbon monoxide detector | Tire chains (optional) |
Essential Items for Your Winter Preparedness Kit
- Water: At least one gallon per person per day for drinking and sanitation.
- Food: A three-day supply of non-perishable food, plus a manual can opener.
- Flashlight and Batteries: For light during power outages.
- First-Aid Kit: With any essential prescription medications.
- NOAA Weather Radio: A battery-powered or hand-crank radio to receive emergency broadcasts.
- Blankets and Warm Clothing: Extra layers are crucial for staying warm if the power goes out.
- Cash: In case power outages prevent electronic transactions.
- Important Documents: Keep copies of insurance policies and identification in a waterproof bag.
- Generator (if applicable): Use only outdoors and away from windows to prevent carbon monoxide poisoning.
