Live: Three dead as Storm Bert claims first victims as two die in car crashed and another is crushed by tree

 The British Red Cross was deployed in Northwich, Monmouthshire and Enniskillen over the weekend to help those evacuated due to Storm Bert and with clean up operations.

They have also offered some tips for what you can do to stay safe during and after a flood.

During a flood     

• Don't walk, swim or drive through floodwater. Six inches of fast-flowing water can knock you over. Two feet of water can float a car.     

• If you need to evacuate, turn off the main power before you leave. You can be electrocuted in floodwater if the power remains switched on. 

• Avoid contact with floodwater. It may be contaminated with sewage.    

• If the flood poses a threat to your safety, call the emergency services immediately.     

• If you need to leave your home and have nowhere to stay your local council will help.     

After a flood     

• Get rid of any contaminated food.  

• Boil tap water or use bottled water until supplies are declared safe.     

• Follow the UK government's advice on how to  keep you and your family safe while cleaning up after a flood.     

• Flooding is a stressful experience. If you need support, call NHS 111 by dialling 111. They’ll tell you about crisis support services.  You can also call the British Red Cross support line on 0808 196 3651 between 10am-12 midday Monday to Friday. You can also request a call back between 10am and 5pm. 

 West Mercia Police said it was aware of videos circulating on social media showing a tractor driving through flood water in Tenbury Wells, Worcestershire, on Sunday, allegedly causing damage to local premises. 

Many business owners in the town have said waves caused by the tractor smashed windows of already-flood-hit premises and worsened flooding in some areas protected by sandbags.

A police statement said: "We're actively investigating the incident and officers are in Tenbury Wells this morning speaking to people whose businesses and properties may have been affected, as well as reviewing additional video footage.

"No arrests have been made at this time. We will provide further updates when we are able to."

National Highways said the A5 in Northamptonshire is closed in both directions between the A43 (Towcester) and A422/A508 (Old Stratford) due to "severe flooding" in the area.

 Specialist contractors are working at the scene to clear the flood water from the carriageway.

The M32 in Bristol was closed in both directions between Junction 1 (Stoke Gifford) and Junction 19 (M4) from late on Sunday night.

It was fully reopened at around 5am on Monday. 

 Great Western Railway said it has suspended service on all key routes due to flooding and fallen trees.

The rail service said it is working hard to reopen the network. Disruption is expected to last until at least end of day on Monday.

Customers are advised not to travel.

This is the shocking moment a tractor driver sends waves of water through shop windows of a flooded town after Storm Bert hit.

The driver can be seen driving through Tenbury Wells, a market town in Worcestershire, which was under several feet of water.

Locals had worked hard to keep the water out, but the tractor's wheels sent large waves out to the side, smashing into the windows of the shops and other businesses.
