Severe Weather Alert: High Winds Associated With Fast-Moving Storms

Understanding the Dangers of High Winds Fast-Moving Storms

Wind Speeds and Damage Potential

The intensity of high winds fast-moving storms is measured by wind speed. Gale-force winds (39-46 mph) can uproot smaller trees, damage power lines, and break windows. Stronger winds, classified as storm-force (47-63 mph) or hurricane-force (above 74 mph), can cause significantly more damage. Hurricane-force winds can demolish buildings, and even stronger winds can cause catastrophic destruction.

39-46 mph (Gale-force): Downed tree branches, power outages, damaged signs.
47-63 mph (Storm-force): Significant tree damage, widespread power outages, structural damage to buildings.
74+ mph (Hurricane-force): Complete roof failure, building collapse, widespread devastation.

The average cost of damage associated with high wind events in the US runs into billions of dollars annually, impacting infrastructure such as power lines, causing transportation disruptions, and leading to significant economic losses.

The Threat of Flying Debris

High winds fast-moving storms transform everyday objects into dangerous projectiles. Flying debris is one of the most significant dangers during these events.

Examples of flying debris: Loose building materials (roof shingles, siding), unsecured outdoor furniture, broken tree branches, signs, and even vehicles.

Securing loose objects before a storm is crucial. Consider bringing loose items indoors, or anchoring them securely. Protecting windows and doors with storm shutters or plywood can significantly reduce the risk of damage from flying debris.

Tornadoes and Downbursts

Fast-moving storms are often associated with tornadoes and downbursts – both extremely dangerous phenomena characterized by intense, localized high winds.

Downbursts: These are strong downdrafts of air that hit the ground and spread outwards in all directions, creating damaging straight-line winds.
Tornadoes: These are violently rotating columns of air extending from a thunderstorm to the ground, characterized by extremely high wind speeds and destructive power.

While both are dangerous, tornadoes are characterized by their rotating winds, whereas downbursts produce straight-line winds. Understanding the differences helps in assessing the specific threats posed by different fast-moving storms.

Safety Precautions During High Winds Fast-Moving Storms

Staying Informed

Monitoring weather forecasts and alerts is critical to staying safe during high winds fast-moving storms.

Reliable sources: National Weather Service (NWS), local news channels, reputable weather apps (e.g., AccuWeather, The Weather Channel).
Alert types: A watch indicates conditions are favorable for the development of severe weather, while a warning means severe weather is imminent or occurring.

Ensure you have multiple ways to receive alerts, including a NOAA weather radio, smartphone apps, and local news broadcasts.

Seeking Shelter

When a high wind fast-moving storm warning is issued, immediately seek shelter.

Recommended shelter locations: Interior rooms on the lowest level of your building (basement is ideal), away from windows and exterior walls.
Shelter preparation: Clear the area around your shelter of any potential hazards.

Avoid windows and areas prone to flooding or damage.

Protecting Your Property

Taking steps to protect your property can minimize damage during a high wind event.

Secure loose objects: Bring all loose outdoor furniture, garbage cans, and other items indoors or securely anchor them.
Protect windows and doors: Use storm shutters, plywood, or tape to reinforce windows and doors.
Protect vehicles: Move vehicles to a sheltered location or garage.

Emergency Preparedness for High Winds Fast-Moving Storms

Building an Emergency Kit

Having a well-stocked emergency kit is crucial for surviving a high winds fast-moving storm.

Essential items: Water (at least one gallon per person per day), non-perishable food, first-aid kit, medications, flashlight, batteries, radio, extra blankets, cash, important documents (copies).
Communication plan: Designate an out-of-state contact person to serve as a central point of contact for family members.

Developing an Evacuation Plan

In some cases, evacuation may be necessary.

Evacuation routes: Identify several possible escape routes and meeting points. Know your local evacuation routes and shelters.
Out-of-state contact: Having a designated out-of-state contact person allows family members to easily check in.

Post-Storm Safety

After the storm passes, proceed with caution.

Assess damage carefully: Avoid downed power lines and damaged structures.
Report damage: Contact local authorities to report damages to infrastructure and buildings.
Stay informed: Monitor for further weather advisories and warnings.

Conclusion

High winds associated with fast-moving storms pose a significant threat. By understanding the dangers, taking necessary safety precautions, and preparing an emergency plan, you can significantly reduce your risk. Stay informed about weather alerts, and always prioritize your safety. Remember to secure your property and be prepared to seek shelter quickly if a high wind fast-moving storm approaches your area. Stay safe and be prepared for high winds fast-moving storms!
