GFM aims to guarantee a high degree of accuracy for all its products, yet users must be aware that a certain degree of uncertainty has to be taken into account.
Therefore, before taking a decision, it is highly recommended to crosscheck GFM's information with other, independent sources such as VIIRS, MODIS, UNITAR, International Disaster Charter, Dartmouth Flood Observatory and others. National hydro-meteorological services are another valuable and authoritative way to check current danger levels.
Please check the full list of the World Meteorological organization (WMO)18 to find the national body corresponding with your region or area of interest.
