Spring is upon us, and the season brings thunderstorms with it in most of the U.S. Thunderstorms mean lighting. Do you know how dangerous lightning is to your electronics? Do you unplug your computers, televisions, stereo systems and any other electronic devices before a storm? If not, why not?

Let me tell you a true story.

Some fifteen years ago, my family and I went to a concert in a city about fifty miles away. It was a great concert and we all had a good time. We noticed on the drive back that there were increasingly large puddles on the
ground as we neared home, but didn’t think much more about it. It was late and we were all exhausted, so we went directly to bed.

My youngest daughter, who has always been an early riser, was the first one up the next morning. Her favorite thing to do at that time was to listen to the radio or a CD on the stereo (with earphones) and rock in the
rocking chair. She was dismayed when she turned on the stereo and found it didn’t work.

Instead she tried to turn on the television, but it wasn’t working either. Since the lights were on, she knew the electricity was functioning, but apparently not much else was. As a last resort, she decided to turn on the
computer and play games. You guessed it. Computer wasn’t working either.

At that point she was still the only person awake, so she grabbed a book and tried to read, but she was understandably pretty distraught.

Once the rest of us got up, we went through the house, checking everything to see what worked and what didn’t. We didn’t know until later, when we talked to neighbors, that there had been a very bad thunderstorm the night before.

There’s no way to know for sure, of course, but we have to assume that lightning hit either our house or one of the power lines very near it. The final tally of destruction: stereo receiver, VCR, television, and computer. We
were fortunate that the television and computer were both older and about due for replacement anyway.

We learned our lesson. Now when there’s a thunderstorm approaching, we unplug everything, not just from the electrical lines, but from the cable as well. If we’re going out of town for a day, we check the weather
forecast. If we’re leaving for longer, we unplug everything just for safety.

Yes, it’s a bit inconvenient, but it would be more than just inconvenient to replace our electronic equipment these days. And since I’m an author and web designer, the loss of a computer would be more than just
inconvenient. It wouldn’t kill my business because I back up relentlessly, including using an automatic, offline back up service in Carbonite. But I would likely lose several days of work time, replacing hardware and restoring software and data.

I’d rather lose an hour of work time than risk losing days’ worth.

I unplug when the weather turns nasty. Unless you live in a place that isn’t prone to thunderstorms, I strongly suggest you do so as well.
