How are the Met Office involved in predicting floods in Scotland?
The Met Office are not responsible for predicting floods but they pass on warnings of heavy rain to SEPA, Local Authorities, Utilities and Media.
They interpret the weather from Satellite images and data.

The National Severe Weather Warning Service (NSWWS) warns the community by providing warning of severe or hazardous weather which could cause problems, ranging from widespread disruption of communications to conditions resulting in transport difficulties or threatening lives.
Early Warnings are issued to the emergency authorities up to several days in advance of an expected event.

Advanced Warnings are issued nearer the expected event, within about 24 hours, to inform the public.
Flash Warnings are more immediate and issued several hours in advance of the event. They provide both the public and emergency authorities with much more detailed timings and movements of the expected events. In exceptional circumstances, an 'Emergency Flash Warning' will be issued.

A Weather Watch issued by the Met Office to the public and emergency authorities if there is a risk of severe weather but the likelihood of occurrence is not great enough for the issue of any of the above warnings. If this likelihood increases, the Weather Watch may be followed by an Early Warning, Flash Warning or Motoring Warning as appropriate.
