Lightning

One of the pleasures of UK winter is the usual absence of thunder and lightning. In the UK they can occur, but they are far more common in the summer. 

Although I know the chances of a direct strike are low, they do occur. I know of 2 friends who had this. One of the more common things is a power surge as storms approach.

What I tend to do is keep a watchful eye on approaching storms. If there is any danger, I disconnect everything: antennas, mains plugs etc.. I have no idea if this is the correct strategy. My view is it is better to be safe than sorry.
