Temperatures set to climb in parts of the UK

Temperatures across the UK are expected to rise on Monday and Tuesday in parts of the UK.

The Met Office have put an amber warning in place for some areas with experts thinking temperatures could climb to 36 or 38C (97-100F).

On Sunday, an official heatwave was declared at Writtle in Essex.

These weather alerts are used to warn the public when high temperatures might be a risk to health or cause disruption to services or travel.

The hottest weather is expected in southern and eastern England, and parts of south Wales.

Europe has been experiencing an intense heatwave across the continent over the last few days.

The heat is being caused by a mass of hot air and the creation of what's called a heat dome.

As the hot air pushes up toward the UK it's thought temperatures could remain high for several days.

The UK is expected to experience warm evenings too with overnight temperatures remaining above 20C (68F) in places.

On Sunday, an official heatwave was declared at Writtle in Essex. It has now seen three consecutive days above the heatwave threshold of 27C.

The Met Office, which monitors UK weather, says a heatwave happens when an area reaches a certain high temperature for at least three days in a row.

Warnings for high UV and pollen levels are also in place.

Experts say heatwaves are happening more regularly and becoming more intense, as a result of climate change.
