Thundery showers are set to hit parts of the UK on 13 June, with the Met Office issuing a yellow warning for rain over the next three days. London and eastern parts of England are likely to be the most affected, with forecasters predicting flooding and disruption to travel throughout much of the week.
The gloomy weather follows one week after torrential rain and thunderstorms hit the UK, causing flash flooding in London. Three people had to be rescued by emergency services on 7 June as the London Fire Brigade responded to reports of cars being submerged in south London.
A chief forecaster for the Met Office said: "Scattered heavy thunder showers are expected to develop, and will once again lead to slow-moving downpours. 15-25mm could fall within an hour, bringing the risk of flooding, especially across urban areas."
The rain warning comes into effect at midday on 13 June, affecting the north west of England, the Midlands, and the south-east. Wales is also covered in the warning areas on 14 and 15 June, while the Environment Agency has issued three flood alerts in the north-west and six in the south-east of England.
The Met Office has described the week's weather as "cyclonic patterns", however, the forecast for the end of the week is set to look brighter. As the weekend begins, the rain is expected to clear and sunny conditions are due to return.
Stormy conditions have been dominating much of Europe, with heavy flooding killing 17 people across the continent in recent weeks. France endured one of the worst storms, which caused the River Seine in Paris to reach its highest level for 30 years on 4 June.
In Germany, more than 70 people were injured by lightning strikes during a concert on 4 June. Later in the week, severe weather warnings for lightning were issued in Denmark, France, Greece, Italy, Luxembourg, Macedonia, the Netherlands, Portugal and Slovenia.
In Northern Ireland, a father and his five-year-old son were crucially injured by lightning outside a school in Lisburn on 7 June. The Northern Ireland Ambulance Service warned the public to avoid water and tall trees during thunderstorms.
