WCM HydroMet Scan for Tropical Cyclones provides information on a specific Tropical Cyclone (TC) and its possible impact. It combines regional, national and local information, based on existing authoritative information (e.g. WMO Members, Regional Specialized Meteorological Centres-RSMCs and Tropical Cyclone Warning Centres-TCWCs, etc.), as well as humanitarian information (e.g. UNHCR locations of forcibly displaced persons).

Example of WCM Success Story: 

Extremely Severe Cyclonic Storm MOCHA in the Bay of Bengal which affected Myanmar and Bangladesh in May 2023. 

This product was prepared by WCM in close collaboration with WMO Secretariat, MeteoSwiss Weather4UN, WMO Tropical Cyclone Program (TCP), Indian Meteorological Department (IMD) / RSMC New Delhi, Bangladesh Meteorological Department (BMD) and Myanmar Department of Meteorology and Hydrology (DMH). This example showed how WCM and WMO community supported the humanitarian agencies: WCM closely monitored the development of this system 10 days before the landfall using the authoritative information from RSMC New Delhi and NMHSs to support UN and HA through various WCM products. This contribution supported UNHCR early action, preparedness and response in the Cox’s Bazar region.
