FLOOD WARNINGS David Kemp Team Leader Flood Resilience
FLOOD WARNING SERVICE Environment Agency provides a FW service for the whole of England and Wales, including Suffolk My team, based in Ipswich, covers from Hunstanton to Purfleet and all the rivers therein. My colleague Adam Foster and his team in Brampton cover the west of the county
Our Aim The service aims to provide 2 hours prior notice of flooding from main rivers or 12 hours prior to flooding from the sea. We warn of flooding from fluvial and tidal sources. The warnings are the same but the timescale and mechanisms are different The intention is to give everyone the opportunity to take appropriate action that will limit the impact of flooding We can not warn of flooding from sewers, burst water mains, or surface water flooding.
Flood Warning Icons Stay Alert Stay vigilant Early precautions Flooding expected Take action Protect yourselves & your property Significant risk to life Significant risk to communities Protect yourselves
Issuing a Flood Warning Forecasting Targeting Dissemination
Forecasting A subject in itself For fluvial flooding we utilise weather radar, rain gauges and river gauges to give 2 hours notice of flooding. For tidal flooding gauges are too late and the latest computer models are used to predict the tide height. 2 – 5 days ahead, probabilistic forecasts Deterministic from 36 hours Every 12 or 6 hours
Targeting Dependant on levels (forecast or actual) we will issue a Flood Alert, Flood Warning or Severe Flood Warning We are able to target the specific locations that will flood rather than stretches of coastline. Thus reducing false warnings and allowing the emergency services to target their resources
Tidal Warnings Issued entirely with reference to forecast Timescales range from 6 hours to 24 hours It is NOT a sequential system – we issue the calculated warning level
Fluvial Warnings Are issued sequentially Lead times 2-4 hours. Assume 2 hours Unlikely to see a Severe Flood Warning – although we have the capability to do so everywhere.
WHO DO WE WARN? Those registered for our service Those who did not opt- out Members of the public within the flood plain property owners within the flood plain Professional Partners County &Local Councils Blue light services Media
How do we warn people? Principal method is to warn people by our automatic telephone message - FLOODLINE WARNINGS DIRECT Up to 5 numbers - can be mobile numbers Text messages faxes s
Basic Parameters AVM telephone lines FWD telephone lines FWD telephone lines FWD telephone lines FWD telephone lines Over a million properties receive our free service
Website www. Environment-agency.gov.uk In 2007 was able to manage 100,000 hits per hour. In 2012 we can manage 2,400,000 hits per hour. Now in the process of revamping the site.
Floodline One stop shop for interrogating the system either via quickdial or via operators. Reporting flooding Flood advice and literature Registering for the system Up to 542 trained staff at 4 sites across the UK Over 10 times the number in 2007 (43)
