This week’s Blog starts with a quick look around at the weather, and luckily according to the Met Office and Environment Agency we in the UK are not forecast any severe weather events as I write this blog. In fact this week looks to be hot and sunny in England and Wales with only the chance of thunder later in the week, these may bring very localised flooding if there is intense local rain, but on the whole there is very little chance of any flood event for the next five days.
On the other hand if you live in North West Florida you will have already felt the effects of Tropical Storm Claudette which thankfully did not get enough time over the warm waters to gather hurricane strength, but towards the end of the week it may be worth keeping a weather eye out for Hurricane Bill and its effects. All the weather models thankfully steer Bill away from Florida but its effects as a heavy rain event may impact on us here in the UK in about 10 days or so, keep an eye on the weather forecast.
It the world of FloodBag we are working with several Local Authorities who are looking to use the FloodBag system to protect school course work and IT equipment from the effects of flooding. A student's coursework is irreplaceable and if it's lost in a flood it can be very distressing and disruptive for the individual.
Our FB08 was designed specifically to take a four drawer filing cabinet so a school or college can protect valuable coursework and files. For more information on the FloodBag call us on freephone 0800 045 7898 or visit www.floodbag.co.uk

Do you know if you are risk from flooding and if so what type of flood waters will affect you?
There are several different types of flooding that occur, each one poses its own set of risks and complications. Here is a brief outline of the different types and where they might occur.
Pluvial flooding can be regarded as flooding that occurs as a result of overland flow of rainfall before it enters a water course or drainage system. Pluvial flooding normally occurs as a result of very intense rainfall (e.g. more than 30mm/1 inch per hour). It can occur with lower rainfall intensities because the ground is saturated, high ground water level, frozen ground, or urban development where the topography causes the water to collect/pond. In Urban areas Pluvial flooding can be caused by the drainage and sewage systems being completely overwhelmed.
Fluvial flooding occurs as a result of a water course (river/stream) rising above its normal channel and spreading on the surround area (floodplain).
Surge conditions are caused by astronomic tide plus storm water and low atmospheric conditions combining to raise water levels, which will be accompanied with large waves that can help drive water in land.
Failure of a reservoir can lead to a catastrophically dangerous body and flow of water downstream from the Dam or reservoir.
Sudden snow melt can lead to a large and quick rise in water levels leading to pooling of melt water and quick rises in water courses.
Water course and Drainage Blockage can lead to a build up a backlog of water that can come back up through the drains and cause localised flooding, in areas that do not normally collect flood waters.
The Environment Agency's website has useful information on types of flooding, and don't forget to look up your postcode on their floodmap to see the threat posed to your home or business.

Worcester flood defences finished
Flood defences have been completed for a road in Worcestershire (UK) badly affected in the summer 2007 floods.
The Environment Agency began work in July 2008 to protect 13 homes and six businesses in Hylton Road, Worcester.
It used 14,000 tonnes of clay from Upton Marina to create defensive flood banks and walls.
It said it had some landscaping work outstanding, but if the river were to rise again the new bank would offer immediate flood protection.
