Understanding the Threat

A heavy thunderstorm warning indicates that severe thunderstorms are imminent or occurring in the warned area. These storms pose a significant threat to life and property due to several potential hazards:

• Damaging Winds: Expect wind gusts exceeding 58 mph (93 km/h). These winds can topple trees, power lines, and cause structural damage to homes and vehicles.
• Large Hail: Hail the size of quarters or larger is possible. Large hail can damage roofs, siding, windows, and crops. It also poses a direct threat to people and animals caught outdoors.
• Flash Flooding: Heavy rainfall associated with thunderstorms can quickly overwhelm drainage systems, leading to flash flooding. Roads can become impassable, and low-lying areas are particularly vulnerable.
• Lightning: Thunderstorms are inherently lightning-producing events. Lightning strikes are a serious hazard, causing fires, power outages, and potentially fatal injuries.

Safety Precautions During a Thunderstorm Warning

Your safety is paramount during a severe thunderstorm warning. Take the following precautions immediately:

• Seek Shelter: The safest place to be is inside a sturdy building. Avoid sheds, carports, and other structures that offer minimal protection. If you are driving, pull over to a safe location away from trees and power lines.
• Stay Informed: Monitor local news, weather radio, or online weather services for updates on the storm’s location and intensity. Be prepared to take further action if the situation worsens.
• Stay Away from Windows and Doors: Keep a safe distance from windows and doors during the storm. These areas are particularly vulnerable to damage from wind and hail.
• Unplug Electronics: Unplug sensitive electronic equipment to protect them from power surges caused by lightning strikes.
• Avoid Water: Stay away from water sources, including swimming pools, lakes, and rivers. Water conducts electricity, making these areas extremely dangerous during a thunderstorm.
• After the Storm: Be aware of potential hazards after the storm has passed. Downed power lines, flooded roads, and weakened trees can still pose a risk. Report any damage to the authorities.

Importance of Preparation

Preparation is key to staying safe during severe weather. Have a plan in place for where to seek shelter and how to communicate with family members. Consider purchasing a weather radio to stay informed during power outages. By taking these precautions, you can significantly reduce your risk of injury or property damage during a heavy thunderstorm.
