The Met Office has issued a new yellow warning for thunderstorms across parts of the UK after the hottest days of the year so far.

The new warning was put in place at noon on Sunday. It will run until 21:00 BST on Monday, the Met Office said.

Forecasters have warned torrential downpours may cause challenging conditions in parts of the UK.

On Sunday afternoon the Parklife festival in Manchester had to be briefly halted as one thunderstorm hit.

In Wales, one weather warning for heavy rain covers a large section of the country apart from the six council areas in the north. It will be in place for Sunday evening into Monday morning.

A yellow thunderstorm warning means there is a small chance homes and businesses could flood quickly and damage buildings.

The Met Office said delays and some cancellations to train and bus services could happen as a result of any flooding or lightning strikes.

Difficult driving conditions could also be expected as a result of spray and sudden flooding and there is a slight chance of power cuts.

The UK Health Security Agency has an amber hot weather alert in place until 09:00 BST on Tuesday for much of south England and the Midlands.

It means high temperatures could affect all ages and impact the health service.

• Hottest day so far this year

A temperature of 32.2°C in Chertsey, Surrey, made it the UK's hottest day of the year too.

Temperatures reached 29.8 C in Auchincruive, Ayrshire, on Saturday - making it the warmest day of the year in Scotland.

The Met Office forecasts that next week the risk of thundery downpours will continue in some areas and temperatures are likely to remain above average.
