Emergency Plan - Fylde Borough Council

Emergency Plan February 2007
Tidal – Flood Warning
1. Triggers
A tidal, surge and/or wind forecast from the Storm Tide Forecasting Service that threshold levels will
be exceeded and flood defences are likely to be overtopped or windblown spray may give rise to
property flooding.
Output from tidal forecasting models run by the Environment Agency, tide detection gauges and
observations.
A breach in the tidal defences or failure of a tidal surge barrier and where the impact with respect to
property flooding is likely to be low to moderate.
A Flood Warning may be issued directly (i.e. without the issue of a Flood Watch) if warranted by a
forecast or observations.
The aim is to issue a Flood Warning to the public at least 2 hours prior to property flooding, but it is
recognised that this is not practicable in all cases.

Location
For specific Flood Warning Areas or groups of Areas i.e. named lengths of coast from Point A to B
Updates
A Flood Warning Update may be issued at any time when new and relevant information becomes
available but when the situation does not warrant the issue of a Severe Flood Warning
Downgrades
Flood Warnings will be targeted for specific tides detailing time of high water and location.
When the tide or tides have passed dependant on local conditions, there may be an automatic
downgrade to Flood Watch.
The Flood Watch will be downgraded to All Clear only when forecasts for subsequent tides are
below the relevant thresholds i.e. there is no longer a possibility of flooding.
5. Dissemination
To relevant outside organisations (including local authorities, emergency services, utility companies,
coastguards etc), the media (local radio stations, television text services, Met Offices Weather
Centres, BBC/Independent Weather Productions (IWP) Weather Centres, travel bulletins etc) and
Floodline
To all public recipients via the Floodline Warnings Direct (FWD) which replaces AVM – and includes
warnings via e-mail, SMS, DAB and Digital TV., flood wardens, sirens, loudhailers etc as
appropriate.
