Winter storms can bring extreme cold, freezing rain, sleet, heavy snowfall and high winds. These conditions can disrupt heat, power and communication systems, posing serious risks to property and personnel. Preparing before, during and after a storm is essential to minimizing damage and staying safe and resilient.

Understanding Winter Weather Alerts

Knowing the terminology helps you respond appropriately:

• Wind Chill Temperature: Wind chill describes how cold it feels on exposed skin due to wind. Limit exposure and ensure employees have proper protection.
• Winter Weather Advisory: Conditions such as light snow or freezing rain are expected and may cause travel delays or minor disruptions. While not extreme, these conditions can become hazardous if precautions aren’t taken.
• Winter Storm Watch: Severe weather, such as heavy snow, sleet or freezing rain, is possible within the next 12 to 48 hours. Use this time to review your emergency plan, confirm supplies, and communicate with your team.
• Winter Storm Warning: Dangerous conditions are imminent or already occurring. At this stage, activate your emergency protocols and prioritize safety measures to protect personnel and property.

Before the Storm

Preparation is key to reducing risk and safeguarding your family, home and business. Consider these proactive actions:

• Review your insurance coverage and confirm property values are accurate.
• Communicate your crisis management plan and confirm roles and responsibilities.
• Inspect heating systems, emergency lighting and generators.
• Secure rooftop equipment and clear roof drains to prevent ice buildup.

During the Storm

• Maintain indoor temperatures at or above 55°F.
• Seal openings to prevent cold air intrusion.
• Monitor official alerts and storm updates.
• Use generators and temporary heaters, prioritizing fire safety practices.

After the Storm

• Account for all personnel and assess property for damage.
• Verify critical systems and report any downed power lines or broken sewer lines to utility providers.
• Remove excess snow from rooftops to prevent collapse or ice dams.
• Document losses before cleanup begins by taking photos of any damage and keeping detailed records for claims.
• Report claims promptly and activate your business continuity plan.
