Should You Open Windows During a Storm?

The age-old question of whether to open or close your windows during a storm has been the subject of much debate. Popular opinion and expert advice often vary, leading to confusion among homeowners. This article aims to provide clarity and offer practical advice based on the most current and effective practices.

Understanding Storm Risks

Storms bring with them a variety of hazards, the most notable being strong winds and flying debris. Opening windows during a storm can pose significant risks, including:

Wind and Debris

Strong winds and flying debris are common during storms. Open windows can allow these elements to enter your home, potentially causing damage to your belongings and even posing a risk of injury. This is particularly dangerous when dealing with hurricanes and tornadoes, where debris can be exceptionally fierce.

Pressure Changes

Opening windows during a storm can disrupt the pressure balance in your home. In severe cases, this can lead to structural damage, as the difference in pressure between the inside and outside of your home can exert substantial forces on your walls and roof (Building science).

Water Intrusion

Water can be a significant threat during storms, especially if rain is involved. Open windows can allow water to enter your home, leading to flooding and extensive water damage. This risk is particularly high in regions prone to heavy rainfall.

Why Closing Windows is Advisable

Considering the potential hazards, it is generally more prudent to keep windows closed during a storm. This helps maintain a secure environment and protects your home from external threats. Here are some additional reasons why closing windows is a safer option:

Enhanced Safety and Security

Closing windows helps maintain a secure environment, especially during high winds and potential tornadoes. Open windows can become entry points for intruders, increasing the risk of theft and break-ins (Homeland security).

Protection During Specific Types of Storms

While it is generally advisable to keep windows closed, there are some exceptions. For instance, during a tornado, opening certain windows can help equalize the pressure inside the house, potentially reducing the risk of structural damage. However, this should only be done under the guidance of storm experts or as part of a verified safe strategy (Weather service).

Regional Considerations

It is important to consider regional differences and local practices. In certain regions, like Southern Florida, where air conditioning is essential, some residents may opt to open windows downwind to ensure the rain does not blow inside. However, this practice is not recommended in most cases, as it does not mitigate other storm-related risks (Weather expert).

Expert Recommendations

Experts now generally advise keeping windows closed during severe thunderstorms. Additionally, it is crucial to maintain a safe distance from windows to avoid lightning strikes. The presence of a tornado can significantly change these recommendations, as pressure relief may be necessary to prevent structural damage.

Prepare for the Worst

Regardless of whether you open or close your windows, it is essential to have a comprehensive storm preparedness plan. This plan should include:

Creating a safe room or designated shelter within your home Securing loose items outside Having a well-stocked emergency kit Staying informed with up-to-date weather reports Knowing the best evacuation routes and procedures

By taking these precautions, you can significantly enhance your safety during a storm, whether windows are open or closed.
