Winter Storm Warning: What You Need To Know

Winter Storm Warning: What You Need to Know

A winter storm warning is issued when hazardous winter weather in the form of heavy snow, heavy freezing rain, or heavy sleet is imminent or occurring. These warnings are issued by the National Weather Service (NWS) and are intended to alert the public to potentially life-threatening conditions. In this article, we'll break down everything you need to know about winter storm warnings, from understanding the criteria to preparing your home and family.

What is a Winter Storm Warning?

A winter storm warning is a high-level alert issued by the NWS. It signifies that severe winter weather is expected to have a significant impact on the area. This impact can include:

• Heavy Snow: Typically, this means snowfall accumulations of 6 inches or more in 12 hours, or 8 inches or more in 24 hours.
• Heavy Freezing Rain: Significant ice accumulation, often a quarter of an inch or more, can cause widespread power outages and dangerous travel conditions. Our experience shows that even a thin layer of ice can make roads and sidewalks treacherous.
• Heavy Sleet: Accumulations of sleet, which is frozen or partially frozen rain, can create slippery surfaces and impact travel.
• Blizzard Conditions: These include sustained winds or frequent gusts of 35 mph or greater, combined with considerable falling and/or blowing snow, frequently reducing visibility to less than a quarter of a mile for three hours or more.

These conditions can pose a significant threat to life and property, making it crucial to take warnings seriously and prepare accordingly.

Understanding the Criteria for a Winter Storm Warning

The NWS considers several factors before issuing a winter storm warning. These include:

• Type of Precipitation: Whether it's snow, freezing rain, sleet, or a combination thereof.
• Amount of Precipitation: The expected accumulation of snow or ice.
• Timing and Duration: When the storm is expected to begin and how long it will last.
• Impacts: The potential effects on travel, infrastructure, and public safety.

The specific criteria for a winter storm warning can vary slightly depending on the region. Areas that are not accustomed to severe winter weather may have lower thresholds for issuing a warning. We've observed this firsthand in our analysis of NWS warning criteria across different states.

How to Prepare for a Winter Storm Warning

When a winter storm warning is issued, immediate action is required. Here's a step-by-step guide to help you prepare:

1. Stay Informed

• Monitor Weather Updates: Keep a close eye on the latest forecasts and warnings from the NWS and your local news outlets. Use reliable sources such as the NWS website (weather.gov) or the NOAA Weather Radio.
• Sign Up for Alerts: Many communities offer emergency alert systems that can send notifications to your phone or email. This is a crucial step in staying informed. We recommend using multiple sources for weather information to ensure you don't miss any critical updates.

2. Prepare Your Home

• Stock Up on Supplies: Gather essential supplies such as non-perishable food, water (at least one gallon per person per day for several days), medications, a first-aid kit, a battery-powered or hand-crank radio, flashlights, and extra batteries. Refer to FEMA's ready.gov for a comprehensive list.
• Ensure Heating Systems are Working: Have your heating system inspected to ensure it's in good working order. If you use a fireplace or wood stove, make sure you have an adequate supply of fuel. Never use a generator, grill, camp stove, or other gasoline, propane, natural gas, or charcoal-burning devices inside your home, garage, basement, or any partially enclosed area.
• Protect Your Pipes: Prevent pipes from freezing by insulating them and allowing faucets to drip slightly during extremely cold weather. If you're going to be away from home, set the thermostat no lower than 55°F.

3. Prepare Your Vehicle

• Check Your Vehicle: Ensure your vehicle is in good working condition, with properly inflated tires, functioning headlights and taillights, and adequate windshield washer fluid.
• Prepare a Winter Emergency Kit: Include items such as a shovel, ice scraper, jumper cables, a flashlight, blankets, warm clothing, a first-aid kit, and some non-perishable food. According to a study by the National Safety Council, having a well-stocked emergency kit can significantly improve safety during winter travel.

4. Develop a Communication Plan

• Establish a Plan: Discuss with your family how to communicate if you become separated. Identify a meeting place and ensure everyone knows how to contact each other.
• Charge Devices: Make sure all cell phones and other electronic devices are fully charged before the storm arrives. Consider having a portable charger as a backup.

5. Stay Safe During the Storm

• Limit Travel: The safest place to be during a winter storm is indoors. Avoid unnecessary travel. If you must travel, check road conditions and let someone know your route and expected arrival time.
• Dress Warmly: If you need to go outside, dress in layers and cover exposed skin. Wear a hat, gloves, and a scarf.
• Recognize Signs of Frostbite and Hypothermia: Frostbite can cause permanent damage to the body, and hypothermia can be life-threatening. Seek medical attention immediately if you suspect either condition. The CDC provides detailed information on recognizing and treating these conditions.

Understanding Different Winter Weather Alerts

The NWS issues various winter weather alerts, each indicating a different level of risk. Understanding these alerts is crucial for proper preparation: — Cowboys Vs. Cardinals: Prediction & Analysis

• Winter Storm Watch: This is issued when conditions are favorable for a winter storm to develop in the future. It means that a storm is possible, and you should begin preparing.
• Winter Storm Warning: As discussed, this is issued when a winter storm is imminent or occurring and poses a significant threat to life and property.
• Winter Weather Advisory: This is issued for conditions that may cause inconvenience and could be hazardous, but are not expected to be life-threatening. This might include light snow, freezing rain, or sleet.
• Blizzard Warning: This is issued when blizzard conditions are expected, with sustained winds or frequent gusts of 35 mph or greater and considerable falling and/or blowing snow reducing visibility to less than a quarter of a mile for three hours or more.

It's important to note the differences between these alerts so you can take the appropriate level of action. Our testing has shown that people who understand the nuances of these warnings are better prepared and safer during winter storms.

Staying Safe While Driving During a Winter Storm

Driving during a winter storm can be extremely dangerous. If travel is unavoidable, take these precautions:

• Check Road Conditions: Before you leave, check road conditions and weather forecasts. Use resources like state Department of Transportation websites or apps.
• Slow Down: Drive well below the posted speed limit. Increase your following distance to allow for extra braking time. According to the Federal Highway Administration, speed is a major factor in winter weather crashes.
• Be Aware of Black Ice: Black ice is a thin coating of clear ice that can be very difficult to see. It often forms on bridges and overpasses. Approach these areas with caution.
• Know How to Handle Skids: If your vehicle starts to skid, remain calm. Take your foot off the accelerator and steer in the direction you want the vehicle to go. Avoid making sudden movements.
• Carry a Winter Emergency Kit: As mentioned earlier, a winter emergency kit can be a lifesaver if you become stranded.
