flood warning

A flood warning or flood alert is the task of making use of flood forecasts to make decisions about whether warnings should be issued to the general public or if previous warnings should be rescinded or retracted. The task of providing warning for floods is divided into two parts:decisions to escalate or change the state of alertness internal to the flood warning service provider, where this may sometimes include partner organisations involved in emergency response; decisions to issue flood warnings to the general public.
