These days with weather forecasts available wherever there is WiFi, it doesn’t do to forget the old ways. Last season I was on passage from North Germany to Denmark. The forecast via the excellent “Passage Weather” site was for 18 knots, maybe up to 22. The local VHF was suggesting similar but was hedging its bets about thunderstorms. As I approached my destination, the barometer, which my wife logs religiously, dumped four millibars in two hours and kept on falling.
