Delhi has seen a few instances over the last few days where the India Meteorological Department's (IMD) forecasts were way off the mark. The most important one was the weather forecast issued on Monday. On Sunday, the IMD had only forecast a "thundery development" for the city on Monday. By the time the Met Office issued an "orange" alert, a fierce thunderstorm, packing winds of up to 100 kilometers per hour had already hit the capital.
