The UK’s third heatwave of the year is set to intensify again this week, following a slight drop in temperatures for some on Monday.
More places in England and Wales could exceed 30C, with some forecasts suggesting that temperatures close to the mid-30s could be possible in a few locations.
Heatwave thresholds may also be briefly reached in parts of Scotland and Northern Ireland as humidity levels increase across the country.
Amber and yellow heat health alerts, external issued by the UK Health Security Agency (UKHSA) are in effect until 21:00 BST on 15 July.
They warn that significant impacts are likely across health and social care services due to the high temperatures, including a rise in deaths, particularly among those with health conditions or aged 65 and older.
Meanwhile, firefighters have been tackling wildfires across England and Wales – with emergency services warning the risk remains “extreme”.
In Conwy in north Wales, a mountain wildfire that broke out on Sunday forced people in a rural community to evacuate their homes. It has been declared a major incident.
One family evacuated from their home said the fire reached their driveway, coming within 200m of their house.
Elsewhere, wildfires burned in Greater Manchester, Hampshire, County Durham, Derbyshire, East Sussex, West Sussex, Devon and Somerset over the weekend.
