Preparing for Strong to Severe Storms: What You Need to Know About Hail Tornadoes and Flash Flooding

Severe storms can strike with little warning, bringing a mix of hazards that threaten safety and property. When strong to severe storms develop, they often produce small to large hail, damaging wind gusts up to 58 mph, isolated tornadoes, and heavy rainfall that can cause flash flooding. Understanding these risks and how to prepare can make a critical difference when the weather turns dangerous.

Understanding the Threats from Severe Storms

Severe storms are complex weather events that can include multiple hazards at once. Here are the main dangers to watch for:

• Hail: Hailstones can range from small pea-sized pellets to golf ball size or larger. Large hail can damage roofs, vehicles, windows, and crops. Even small hail can cause injuries if caught outdoors.

• Strong Winds: Gusts reaching 58 mph or more can snap tree branches, down power lines, and cause structural damage. These winds can also make driving hazardous.

• Isolated Tornadoes: Tornadoes may form in some storms, though they are not always guaranteed. Even isolated tornadoes can cause severe damage along their path.

• Flash Flooding: Heavy rainfall over a short period can overwhelm drainage systems and cause rapid flooding. Flash floods can sweep away vehicles and flood homes quickly.

  
  

Widespread power outages are also possible during these storms due to downed lines and damaged infrastructure. Preparing for outages is essential.

How to Prepare Your Home and Property

Taking steps before a storm hits can reduce damage and keep your family safe. Consider these actions:

• Secure Outdoor Items

Bring in or tie down patio furniture, trash cans, and other loose objects that strong winds could turn into projectiles.

• Protect Windows and Roof

Close storm shutters or cover windows with plywood if large hail is expected. Inspect your roof for loose shingles and repair them.

• Clear Gutters and Drains

Remove leaves and debris to help rainwater flow freely and reduce the risk of flash flooding around your home.

• Trim Trees and Branches

Cut back weak or overhanging branches that could fall on your house or power lines during high winds.

• Prepare for Power Outages

Have flashlights, batteries, a battery-powered radio, and a supply of water and non-perishable food ready. Consider a generator if outages are common in your area.

What to Do When a Severe Storm Approaches

When weather alerts warn of strong to severe storms, follow these safety tips:

• Stay Informed

Use a weather app, NOAA weather radio, or local news to get real-time updates. Pay attention to warnings about hail, tornadoes, and flash flooding.

• Find Shelter

Move indoors immediately. Stay away from windows and glass doors. If a tornado warning is issued, go to a basement or an interior room on the lowest floor.

• Avoid Driving

Do not drive during severe storms. Wind gusts and hail can make roads dangerous. Flash flooding can trap vehicles in water.

• Protect Yourself from Hail

If caught outside, seek shelter under a sturdy structure. Cover your head and neck to avoid injury from hailstones.

• Prepare for Flash Flooding

If you live in a flood-prone area, be ready to evacuate quickly. Never walk or drive through floodwaters.

Recognizing Signs of Tornadoes and Flash Flooding

Knowing the warning signs can save lives:

• Tornado Signs

- Dark, often greenish sky

- Large hail followed by sudden calm

- Loud roar similar to a freight train

- Visible funnel cloud or debris cloud near the ground

• Flash Flood Signs

- Rapidly rising water in streams, rivers, or streets

- Heavy rain lasting more than 30 minutes

- Water flowing where it normally does not, such as roads or low-lying areas

If you notice these signs, act quickly to protect yourself and others.

After the Storm: Safety and Recovery

Once the storm passes, hazards may still exist. Follow these guidelines:

• Avoid Downed Power Lines

Treat all downed lines as live and report them to authorities.

• Check for Injuries

Provide first aid if needed and seek medical help for serious injuries.

• Inspect Your Home

Look for structural damage, broken windows, and roof issues. Document damage for insurance claims.

• Be Cautious of Floodwaters

Avoid walking or driving through floodwaters. They may be deeper or faster-moving than they appear.

• Stay Updated

Continue listening to weather reports for additional warnings or emergency instructions.
