About Thunderstorms (and Lightning)
Thunderstorms, sometimes called electrical storms, lightning storms, or thundershowers, are not by themselves the greatest cause of damage and injury. However, thunderstorms can create lightning, hail, strong winds, tornadoes, and flash floods. These related occurrences are the reason it’s important to take thunderstorms seriously and to be prepared ahead of time.
Lightning is probably the greatest threat from a thunderstorm. Lightning is responsible for killing 300 people every year. This is primarily because lightning is unpredictable. It can strike during heavy rain, and can even strike at distances of 10 miles away from any rain. Most fatalities occur to people caught outside during the summer months.
Authorities issues two different types of thunderstorm warnings:
A thunderstorm in your area is likely.
A thunderstorm in your area is occurring, or will likely occur soon. Take shelter immediately if asked to do so by authorities.
Important Thunderstorm Preparedness Tips
- Go inside if, there is less than 30 seconds between the time you see lightning, and the time you hear thunder. Remain indoors for at least 30 minutes after hearing the last thunder clap.
- Remove dead trees and branches that could fall during a severe thunderstorm.
- Secure outdoor objects that could blow away or cause damage. Consider moving these objects inside a garage.
- Shutter windows and secure outside doors. If shutters are not available, close window blinds, shades or curtains. This will help prevent injuries should your windows break.
