Flooding awareness - updated 25/07/2014

Manx Utilities is working closely with various agencies across Government including Ronaldsway Met Office, the Emergency Planning Office/Civil Defence and the Department of Infrastructure, to improve public awareness and guidance in relation to the Island’s response to flooding.

Manx Utilities staff will be attending the 2014 Agricultural shows and, with assistance from our colleagues at the Met Office, will be highlighting an informative range of topics, including how you can ‘Be Flood Prepared’ and help to protect your property or business from a risk of flooding

Please be aware there are several high spring tides forecast over the coming months, notably between:

• 10th - 15th August 2014:

• Spring tide maximum height - 13th August at 01:38 BST

• 8th - 12th September 2014:

• Spring tide maximum height - 11th September at 01:16 BST

Spring high tides are higher than normal high tides and occur twice in a lunar month. Even though spring tide heights can be forecast, weather conditions can significantly affect final heights. If high spring tides occur at the same time as low pressure weather systems, then they have the potential to cause flooding, as seen earlier this year and in previous years. Early indications are that there will not be particularly adverse weather conditions on these forthcoming occasions, however, Ronaldsway Met Office will continue to monitor the situation and will keep the various agencies and the public informed if weather conditions become likely to cause a risk of localised flooding at any time.

There are various ways to keep up to date with the weather forecast and also monitor flood risk in your area:

• Isle of Man weather forecast: www.gov.im/weather

• Local radio: Manx Radio, Energy FM and Three FM

• Isle of Man Floodline, 686100 (calls charged at local rate) - a recorded message provides current flood warning status for the Island and more detailed information about any flooding expected. The message is updated as required by the duty Forecaster at Ronaldsway Met Office

• www.gov.im/floodwatch - local flood warning information provided by Ronaldsway Met Office

• Manx Utilities website: www.manxutilities.im - flood maps and further information and advice are available on this website

• Social media sites: www.twitter.com/manx_utilities / www.facebook.com/manxutilities

By taking appropriate action and being flood prepared you can minimise the potential effects of flooding to your property.

If you have any further queries our Network & Client Services Team can be contacted on 687687 (option 2).

Flooding Information - updated 03/02/2014

Flood Map displaying the indicative 1 in 100 year river and 1 in 200 year tidal flood outlines. Please note the Flood Map only shows the predicted likelihood of flooding from rivers or the sea for defined areas and is not sufficiently detailed to account for individual addresses. Individual properties may, therefore, not always be at the same risk of flooding as surrounding areas/properties. If you believe that a particular property has a different risk of flooding to that shown on the Flood Map and/or if you have information you believe the Manx Utilities Authority (“MUA”) may not have taken into account when preparing the Flood Map please contact MUA.

Climate Change is accounted for in the river flood by increasing the 1 in 100 year peak flow estimate by 20%. For the tidal flood, an annual climate change allowance has been added for sixty years.

Whilst flood defences may be indicated on the Flood Map, given that they do not completely remove the risk of flooding and can be breached or fail in extreme weather conditions the Flood Map does not take into account flood defences and/or the effect any such defences (in place now or in the future) may have on the risk of flooding.

As and when additional relevant information becomes available to MUA the Flood Map will be improved and updated. The Flood Map was produced on behalf of the MUA and all or any intellectual property rights in and to the Flood Map vest in the MUA.

MUA believes that the Flood Map and information contained therein accords with the information currently available to it, but no representations or warranties (express or implied) are given with regard to the accuracy of the Flood Map. To the fullest extent permitted by law the MUA will not accept liability for any losses resulting in connection with the Flood Map.

Mapping is based upon the Isle of Man survey map with permission of the Department of Infrastructure.
