Even as Cyclone Michaung heads towards the south Andhra Pradesh coast, triggering torrential rain in Chennai and north Tamil Nadu, another system is brewing over the Arabian Sea according to the global models. The models by the European Centre for Medium-Range Weather Forecasts (ECMWF) and Global Forecast System (GFS) hint at the formation of a cyclonic system over the Arabian Sea soon after the dissipation of Cyclone Michaung.
However, a clear picture of the emerging system will be known only after the dissipation of the current one over the Bay of Bengal, according to the India Meteorological Department (IMD) sources. The weather bulletin issued by the IMD on Monday said a cyclonic circulation lies over the southwest Arabian Sea, extending up to 3.1 km above mean sea level. The extended forecast issued by the IMD also forecast above normal rainfall in Kerala during the second week of December.
