Weaver, If I hear on the weather forecast that a storm may be coming - even where I live, outside London - I put the radio on to listen to the clicks and bangs to warn me of problems to come. does give false positives, but allows me to play safe. In the case of bad storms coming it alows me to disconnect my Sky FTTC modem/router, and change wirelessly to my son's Virgin line, taking all my VOIP lines as well ! So in answer to your question I would definately, if I were you, listen to your long wave radio. Bear in mind that the Met Office does the same thing, but on much lower frequencies...........
