According the to the WMO, a global initiative to improve early warnings of flash floods has advanced in South Asia, just as the region is hit by unusually heavy monsoon rains and floods.

The India Meteorological Department (IMD), Regional Center of South Asia Flash Flood Guidance System, conducted online training for 130 forecasters from Bhutan, Bangladesh, India, Nepal and Sri Lanka earlier this month.

The department’s aim is to integrate flash food guidance products into operational forecasts which can be used by disaster managers both throughout India and in other participating countries by harnessing new technology, forecast tools, super computers and local expertise. It is part of the WMO’s global system which currently provides early warnings to three billion people – 40% of the world’s population – across more than 60 countries.

Flash floods and riverine floods contribute to major loss of life and property in South Asia during the monsoon season. Currently many Indian states in the Eastern Himalayan region are facing severe flood situations in major river basins.

“Thousands of people die in riverine and flash floods. Many of them could be saved by improved early warnings, information about the risks of these sudden-onset events and better water resource management. The training program is very important to ensure that the Flash Flood Guidance System is established and sustained for the Regional and National Centers in South Asia, which is a region prone to natural hazards such as flash floods, riverine floods and tropical cyclones,” said Hwirin Kim, head of WMO Hydrological and Water Resources Services Division.

The three-day training program, held virtually because of the Covid-19 pandemic, provided hands-on exercises and shared recent case study analysis from participating countries. A 30-day operational online information technology training session is also being given to 15 selected experts to ensure that the system is sustainable.

IMD said it provides value-added quantitative precipitation forecasts for the 153 flood-prone river basins through its 14 flood meteorological offices established across the country. A two-day online training program on July 1 and 2, 2020, was successfully conducted for 50 forecasters by IMD’s Hydromet Division, for improving the flood meteorological services of the country.

“These ambitious services and new initiatives have become a reality in this monsoon season and will definitely help in its sustainability in future,” said Dr. Mrutyunjay Mohapatra, director general of IMD.

“These trained forecasters will start operations across the region at local level for the whole flood season with the support and guidance of Regional Centre at New Delhi,” said B P Yadav, deputy director general (Hydromet) & head of regional operations of the South Asia Flash Flood Guidance System.

The South Asia Flash Flood Guidance System was launched in 2016, covering Bangladesh, Bhutan, India, Nepal and Sri Lanka. The India Meteorological Department (IMD) was selected as the regional center to provide forecast products and data to the participating countries and conduct verification studies in collaboration with the NMHSs (National Meteorological and Hydrological Services) and WMO.
