Some parts of England and Wales have seen a yellow thunderstorm warning upgraded to amber for this evening (Saturday, June 10).

It will affect parts of north-eastern Wales, the west Midlands and the north-west of England.

The Met Office weather warnings page states that it will last from up until 9 pm today.

It comes as a number of areas across the southeast hit 30C on Saturday, with yellow thunderstorm warnings in place for much of the country over the weekend, Sky News reports.

Another yellow warning is in place on Sunday from midday to 9 pm for Wales, Northern Ireland and most of western and central England and Scotland.

What to expect with amber weather warning

In terms of what an amber weather warning could bring, the Met Office state:

  • Flooding of homes and businesses is likely and could happen quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds
  • Fast flowing or deep floodwater is likely, causing danger to life
  • Where flooding or lightning strikes occur, delays and some cancellations to train and bus services are likely
  • Spray and sudden flooding probably leading to difficult driving conditions and some road closures
  • Some communities likely to become cut off if roads flood
  • Power cuts likely to occur and other services to some homes and businesses could be lost

The UK Health Security Agency (UKHSA) has also issued an amber heat-health alert for hot weather until 9am on Tuesday in the West Midlands, East Midlands, East of England, South East and South West.

It means the impact of the heat is "likely to be felt across the whole health service… and the wider population, not just the most vulnerable".
