Will release impact-based cyclone warnings for districts this season: IMD

New Delhi, Oct 09: The India Meteorological Department will release dynamic impact-based cyclone warnings for districts this season to help minimise economic losses and damage to property due to the intense weather system, Director-General Mrutunjay Mohapatra has said.

The months before and after monsoon form the cyclone season. Storms during October to December, especially in the Bay of Bengal, often ravage the eastern coast and damage property.

Speaking at an event here on 'Chasing the Cyclones', Mohapatra said the new system will give specific warnings.

For instance, if a district is to be hit by winds up to 160 kmph, it will warn about the kind of infrastructure that is likely to be damaged and these can be mapped.

Under the system, location or district-specific tailored warnings, which factor in the local population, infrastructure, settlements, land use and other elements, will be prepared and disseminated.

All disaster management agencies will make extensive use of cartographic, geological and hydrological data available for the district concerned.

The system will be set up through a dynamic composite risk analysis Atlas being developed by the National Disaster Management Authority (NDMA) under the National Cyclone Risk Mitigation Project in collaboration with coastal states and the Ministry of Earth Sciences and other agencies.

This will include information on major infrastructure projects like roads and railways, hospitals, cyclone shelters and the possible impact of the storm on them.

"With India's growing economy, we aim to reduce the damage and economic losses caused to property and infrastructure. The dynamic, impact-based cyclone warning will be commissioned from this season," Mohapatra added.

Until now, the IMD gave warnings about the kind of damage expected during a cyclone.

The NDMA is executing the project and developing a web-based Dynamic Composite Risk Atlas (Web-DCRA) in collaboration with IMD and coastal states.

At the event organised by Indian Society of Remote Sensing's Delhi chapter on Tuesday, Mohapatra also pointed out that the damage caused to infrastructure due to cyclones is increasing worldwide.

Separately, the IMD director general reviewed preparedness ahead of the season.

The meeting was attended by experts from IMD, National Centre for Medium-Range Weather Forecasting, Indian Air Force, Indian Navy, Central Water Commission, India Institute of Technology-Delhi, Indian National Centre for Ocean Information Services, National Disaster Management Agency, National Disaster Response Force, Department of Fisheries, Punctuality Cell and the Indian Railways.

At the meeting, Mohapatra stressed on the need to learn lessons and fix the recurring mistakes. He also insisted on developing a fool-proof triggering and response mechanism with active participation from all the stakeholders.

He said the IMD this cyclone season will also launch an interactive display system to forecast cyclone track and intensity on GIS platform.
