Weekly Safety Topic – Severe Weather / Lightning

SEVERE WEATHER PREPAREDNESS

About 1800 thunderstorms are ongoing at any time somewhere on earth, which amounts to 16 million storms a year. These storms produce about 25 million lightning strikes per year.

Lightning is very dangerous and even 5 times hotter than the sun so it should be taken seriously when there is a threat nearby. Many cases people wait until it starts raining but if you think about it, rain is not the threat, lightning is.

You can be struck by lightning under clear blue skies even when the actual storm and rain is 10 miles away.

What causes Lightning? Particles of ice, rain or snow collide within the cloud, changing the charge of the lower portion of the cloud. Objects on the ground become positively charged, which causes electrically charged particles to balance each other, resulting in a bolt of lightning.
If caught outside the best place to go is inside, if there is no building or house nearby a car is the next best option.

If you are at an outdoor event, do not wait until authorities tell you to seek shelter if you hear thunder take action and protect yourself by getting into a safe spot until the storm and threat of lightning passes.

The National Weather Service (NWS) provides three levels of seriousness relating to storms approaching your area. A simple way to remember them is.
