High winds can occur during a severe thunderstorm, with a strong weather system, or can flow down a mountain. When winds are sustained at 40-50 mph, isolated wind damage is possible. Widespread significant wind damage can occur with higher wind speeds. During strong thunderstorms, straight line wind speeds can exceed 100 mph. High winds can blow objects around and pose a significant threat to your safety. Understanding the risks can help you prepare for these events. If you, or someone you know, have been a victim of a high wind event, please share your story so we can prevent others from becoming a victim. Read wind survivor stories. When you write, please note that NWS has permission to use your story and, if possible, let us know the town and state you were in and the year the event took place.
