Globally, weather forecasters run multiple models by keying-in the latest atmospheric and/or oceanic initial conditions as data feeds. They use high performance computers to run these models which in turn provide output, whose interpretation is issued as weather forecasts. Currently, the IMD operates Coupled Forecasting System (CFS) developed under the Monsoon Mission Project. The original model framework of CFS was developed by US-based National Center for Environmental Prediction.

Authorities are closely monitoring the southern coast of Kerala following the capsizing of a Liberian-flagged container ship in the Arabian Sea on Saturday afternoon. The vessel, en route to Kochi Port from Vizhinjam near Thiruvananthapuram, tilted in rough sea conditions before multiple containers — some reportedly carrying “hazardous cargo” —fell into the water and began to sink by Sunday, officials said. As of Sunday, no oil spill has been reported.

The IMD declares the monsoon’s arrival over Kerala based on three primary indicators: rainfall of at least 2.5 mm recorded at a minimum of 14 meteorological stations for two consecutive days, deep westerly winds extending up to 600 hectopascals, and a decline in Outgoing Longwave Radiation values below 200 watts per square meter. This early onset signals the beginning of the crucial four-month-long rainy season, vital to agriculture, water resources, and economic stability across the country.
