Thunderstorms
Almost every spring and summer, we talk about severe thunderstorms. This may not be as interesting a subject as hurricanes, tornados, or ice storms but severe thunderstorms can be very common for our area and they can cause extensive damage. Union County Fire Department/EMA would like to provide some information on thunderstorms and what you can do to keep safe.
The summer heat and humidity provide the right conditions for the development of these severe thunderstorms. They can pop-up suddenly and produce heavy rain, dangerous lightning, and flash floods, especially in our mountain terrain.
The first step in being prepared is to stay informed. Television, radio, social media, and cell phone apps can provide information on severe weather events. Knowing the difference between a Severe Thunderstorm Watch and a Warning can be very helpful. A Severe Thunderstorm Watch means severe thunderstorms are possible and we should be prepared. A Severe Thunderstorm Warning means a severe storm is expected and we should take shelter. Warnings indicate imminent danger to life and property.
Lightning that is associated with severe thunderstorms can be very dangerous. If you can hear thunder, then there is the potential for lightning in your area. The best practice for possible lightning near you is to get indoors and avoid possible conduction areas. If in a forest, seek shelter in a low area under a thick growth of small trees. If in an open area, go to a low place such as a ravine or valley. Be alert for flash floods. If on open water, get to land and find shelter immediately.
Thunderstorms can also produce heavy rain in a small area and in a short amount of time. This heavy rain can make driving very dangerous due to water on the road and lack of visibility. The best practice is to slow down; increase distance between vehicles or even pull into a parking area until it passes.
The heavy rain can also produce flash flooding. Avoid moving water and never drive through running water. Just six inches of moving water can knock you down and two feet of water can sweep your vehicle away. If there is a chance of flash flooding, move immediately to higher ground.
We all want to enjoy our summer but we must keep safety in mind. Stay informed of potential severe weather. Be aware of any possible thunderstorms and know the watches and warnings. Be ready for lightning, heavy rain, and possible flash flooding that may be associated with these thunderstorms. Union County Fire Department ~Our Family Protecting Your Family~
