What is a red severe weather warning?

The Met office issued a red weather warning when “dangerous weather is expected”.

When this kind of alert is issued you should take action to keep yourself and others safe from the impact of the severe weather, if you haven’t already done so.

The Met Office is forecasting an exceptional hot spell on Monday and Tuesday leading to “widespread impacts on people and infrastructure”.

What weather warnings mean

Cabinet Office minister Kit Malthouse has said the Government is preparing for a “surge” in demand on the NHS and other services due to the expected heatwave.

After chairing a meeting of the Cobra civil contingencies committee in Whitehall, Mr Malthouse urged the public to look out for people who were particularly vulnerable in the heat.
