The India Meteorological Department (IMD) has issued its first official forecast for 2018 southwest monsoon rains in New Delhi on April 16, 2018. The second stage forecast will be issued in June 2018. These forecasts are prepared using state-of-the-art Statistical Ensemble Forecasting system that is critically reviewed and improved regularly through in-house research activities. It accounts for about 70% of the country’s annual precipitation. This is an annual event that sets the tone not only for agricultural production but also the manner in which the economy, stock markets, inflation and interest rates would move in the year. Monsoon rains is the lifeblood for India’s farm-dependent 2 trillion dollar economy. The June-to-September rains are vital for farming. IMD is headquartered in Delhi and operates hundreds of observation stations across India and Antarctica.
