In many areas of the country, a winter storm brings in snow, ice, and freezing temperatures. While we often associate these storms with power outages and icy roads, the risk of flooding after the storm is greatly underestimated.

Winter storm flooding can cause some of the most devastating damages to homes, businesses, and infrastructure. From ice jams to frozen pipes and, yes, even storm surges, winter storms have the potential to leave communities with hefty repair costs. The question is: how do we prepare for winter storm flooding?

In this blog, we cover common winter storm problems and some of the most effective flood prevention strategies.

Common Winter Storm Issues 

1. Snowmelt Flooding

When temperatures suddenly rise after heavy snowfall, the accumulated snow melts rapidly, leading to snowmelt flooding. This is particularly problematic in areas with poor drainage systems or frozen ground that prevents water from being absorbed. The runoff can overwhelm stormwater systems, causing localized flooding.

2. Ice Jams

When chunks of ice accumulate and block rivers or streams, it causes water to back up and flood surrounding areas, also known as ice jam flooding. This type of flooding often happens during periods of fluctuating temperatures, where melting ice refreezes downstream.

3. Coastal Flooding and Storm Surges

Winter storms often bring strong winds and low-pressure systems, which can result in storm surges along coastal areas. Combined with high tides, this can lead to severe flooding, especially during nor’easters or polar vortex events.

4. Frozen Pipes and Bursting

While not direct flooding, frozen pipes are a common winter storm issue that can lead to flooding when they burst. This can cause water damage to homes and businesses, particularly if the issue goes unnoticed for hours or days.

5. Blocked Storm Drains

Snow and ice can clog storm drains, preventing water from draining properly. This can lead to pooling water on streets and around buildings, increasing the risk of localized flooding when rain or snowmelt occurs.

6. Flash Flooding from Winter Rain

Winter storms often bring rain along with snow, especially in warmer climates. Heavy rainfall on snow-covered ground can lead to flash flooding, as the rainwater has no place to go.

7. Roof Collapses and Flooding

Heavy snow and ice accumulation on roofs can cause structural damage, including roof collapses. When snow melts, it can leak into the property, causing interior flooding and water damage.

8. Frozen Ground That Prevents Absorption

When the ground is frozen, it cannot absorb water effectively, causing rain or melted snow to flow across the surface rather than being absorbed into the soil. This contributes to localized flooding and water pooling around structures.

The Best Flood Prevention Strategies This Winter

While you can’t prevent winter storms, you can mitigate the risks of flooding by taking proactive measures:

1. Inspect and Maintain Drainage Systems

Ensure gutters, downspouts, and storm drains are clear of debris and functioning properly. Install gutter guards to prevent ice and debris buildup, and direct downspouts away from your property’s foundation.

2. Install Flood Barriers

Customizable flood panels are incredibly effective in protecting vulnerable areas like basement entrances, doors, and windows. These barriers are easy to install and can be stored for emergencies.

3. Seal Basement Walls and Foundations

Cracks in foundations and basement walls are common entry points for floodwaters. Apply waterproof sealants to these areas to prevent leaks during heavy rain or melting snow. Regularly inspect your foundation for cracks and repair them promptly.

4. Ensure Proper Grading Around Your Property

The ground around your property should slope away from the foundation to direct water away. Poor grading can lead to pooling water and increased flood risk. Consider regrading your yard or installing a drain system to improve drainage.

5. Install a Sump Pump

A sump pump can be a lifesaver during winter storms, especially in areas prone to flooding. Ensure your sump pump is in working condition before the storm season, and consider installing a backup battery system to keep it operational during power outages.

6. Invest in Flood-Resistant Materials

If you live in a flood-prone area, consider renovating with flood-resistant materials. Use water-resistant flooring, insulation, and drywall in basements and other vulnerable spaces. This investment can reduce damage and cleanup costs after a flood.

7. Create a Snow Removal Plan

Excess snow accumulation near your property can lead to flooding during a sudden thaw. Have a snow removal plan in place to ensure snow is cleared from roofs, driveways, and areas near your foundation. Consider using professionals for safe snow removal from roofs to avoid ice dams.

8. Monitor Weather Alerts and Flood Risks

Stay informed about weather forecasts and flood advisories. Sign up for local alerts and invest in a flood monitoring system to detect water levels near your property. Early warnings can give you valuable time to deploy flood barriers or take other protective measures.

9. Prepare Emergency Flood Supplies

Have an emergency flood kit ready, including items like a portable sump pump, waterproof tarps, and submersible pumps. These tools can help mitigate damage if floodwaters begin to enter your property.

10. Work with Flood Response Experts

Flood prevention requires expertise and planning. Partner with flood response professionals to assess your property’s vulnerabilities and develop a tailored flood protection plan.
