Amber warning as thunderstorms set to bring flash floods

 

Parts of the UK are bracing for potentially dangerous flash flooding as thunderstorms and torrential rain are set to arrive over the weekend.

An amber weather warning came into effect on Saturday morning, when more than a month's worth of rain is forecast to fall in a matter of hours.

The Met Office predicts that fast-flowing and deep floodwaters are likely, resulting in road and transport disruptions, as well as power outages.

The warning for torrential downpours comes days after a third UK heatwave of the year that parched swathes of the UK and led to several hosepipe bans being declared.

This will increase the likelihood and severity of flooding, as the dry ground will be unable to absorb as much water.

The amber warning covers a stretch of the south coast, London, and Cambridge, and is in force from 04:00 BST to 11:00 on Saturday.

Between 20 and 40mm of rain could fall within an hour in this area, the Met Office has warned, which could accumulate to 70-100mm in just a few hours.

It said homes and businesses are likely to be flooded, which will happen "quickly", while this amount of surface water will make driving difficult and may lead to road closures.
