Good grief! Sitting here minding my own business about 10 mins ago, had been keeping an eye on the Nowcast site, nothing much happening, when suddenly the computer, sky box, router etc all went off, house alarms in road all going off, crack of thunder. Extremely heavy rain (got to an inch deep on the patio, deeper on the road outside as drains couldn't cope). Sadly not much in the way of lightning. All appears to have passed over now. Livened up a quiet sunday morning! As I type another flash and rumble has just happened, probably sensible to turn off the computer now!
