What are the consequences and what we can do to reduce impacts of storms and floods?

Consequences

Consequences of storms are largely down to one (or both) of two things; wind and precipitation

Wind is air moving from one place to another. 

Precipitation is water which comes from the air to the surface, it includes:

Includes    
Rain Snow Sleet
Drizzle Dew Frost
Fog Mist Rime

The biggest danger of high winds are when things are blown over; these can include trees, powerlines, chimneys and even lifting roofs off of buildings. 

Recent UK storms have seen large objects such as sheds and large trampolines being lifted from the ground and as high as 20 metres into the air.

Falling trees can be dangerous to life but most impacts are when powerlines are brought down and power is cut to homes and businesses.

The biggest risks from precipitation come from flooding as a result of heavy rainfall.

Snow and ice brings different risks cutting off transport routes and posing a risk of slips, falls and traffic accidents.

Who is responsible for flood protection?

The simple answer is everyone, most people would answer the government or the council but YOU are responsible for YOUR safety along with your parents and other family members. 

The governments within the UK help through agencies such as Natural Resources Wales (NRW) in Wales and the Environment Agency (EA) in England. Local councils also have a role to play but the most important person is you!

When we think about preparing for flooding we think about big expensive schemes such as this one in York which failed during Christmas 2015 causing widespread flooding.

Here the local council are providing sandbags to build a temporary barrier and local people are being helped by members of the army to lay them out.

It is very important that river and stream channels are kept clear here we can see government workers involved in this but it is the land owners on either bank who actually own the river or stream and as such they have legal responsibilities.

How can we prepare for flooding?

The NRW (Natural Resources Wales) website tells us to: 

Check your flood risk on the NRW flood risk map. You can find out what the chance of flooding from rivers and the sea is in your local area on the flood map.
