South Asian Flash Flood Guidance System

The World Meteorological Organisation (WMO) and few South Asian countries expressed the importance of the project, put forth their views and the urgent need for such a warning system.

What are Flash Floods?

Flash floods are sudden surges in water levels during or following an intense spell of rain. They are highly localised events of short duration with a very high peak and usually have less than six hours between the occurrence of the rainfall and peak flood. The flood situation worsens in the presence of choked drainage lines or encroachments obstructing the natural flow of water.
