3. (6) The Environment Agency and the
Met Office should work together,
through a joint centre, to improve
their technical capability to forecast,
model and warn against all sources
of flooding
(34) The Met Office and the
Environment Agency should issue
warnings against a lower threshold
of probability to increase preparation
lead times for emergency
responders.

• Soil moisture content

Not just weather!
30. Forecast flows from each
grid cell are converted to
return period flows (QT
grids)
G2G flows presented as return periods
31. G2G return periods - National Overview
Final steps are to
summarise this
information as a
‘maximum status’ of
return period flow
exceedance for each
county over a chosen
time interval (e.g. 24
hours)
And then link this in
with risk levels on
FGS

Modelling is at 1 km grid squares, but output is designed to be
used at lower resolution due to uncertainties in the forecasts and
to input into the Flood Guidance Statement.
38. Expertise in Hydrometeorology:
• Holistic approach to flood forecasting
• New services for surface water and public
• A framework for up-skilling in the industry
• Greater trust by raising industry standards
and improving communications
• Efficiencies and value for money
