The weather map for Monday with the highest temperatures in the east
The Met Office has put Wales on the brink of a heatwave as an amber heat warning has been put in place for parts of England. For Wales to have a heatwave, it has to be 25°C for three days in a row.
And weather maps from the meteorological service show that temperatures fall just outside that in the coming days. Mike Silverstone, a deputy chief meteorologist at the Met Office predicted that the east of Wales looks set to get the hottest weather.
He said: “Higher temperatures building over the weekend and into early next week will bring particularly warm, hot or even very hot conditions for some, especially in the southeast and east Anglia and more locally elsewhere in England and east Wales. This in part will be influenced by a heatwave developing across western Europe.
“By the weekend, an area of high pressure will be intensifying and dominating the UK forecast. Conditions will be hottest in the south and east while areas further north and northwest will be relatively cooler.”
On Friday, Wrexham, Monmouth, and Chepstow will experience the hottest temperatures in Wales, with 24°C at 3pm. It will also be 23°C in Hay-on-Wye and Newtown.
On Saturday, Welshpool and Wrexham will enjoy temperatures of 24°C. It will be 23°C in Flint. Then on Sunday, temperatures will rise to 25°C in Hay-on-Wye, 25°C in Wrexham and Welshpool, and 24°C in Brecon and Builth Wells.
Monday is set to be very hot in parts of Wales, with Monmouth set for 30°C, Chepstow and Abergavenny 29°C, Newport and Hay-on-Wye 28°C, Welshpool 27°C, and Cardiff, Brecon, Newtown and Builth Wells 26°C temperatures.
The UK Health Security Agency, which looks at potential impacts in the health and social care sector in England, has put an amber health warning in place for east Midlands, the east of England, London, the south east, and south west, starting from June 27 at 12 noon until July 1 at 6pm.
The agency says that significant impacts are likely across health and social care services due to the high temperatures, including a rise in deaths, particularly among those ages 65 and over or with health conditions. It says there may also be impacts on younger age groups.
It adds that it is likely to increase demand on all health and social care services, and that internal temperatures in care settings (hospitals and care homes) may exceed recommended threshold for clinical risk assessment, with the heat affecting the ability of the workforce to deliver services.
It says there is also a risk of indoor environments overheating, increased the risk to vulnerable people living independently in community and care settings, issues managing medicines, and staffing issues due to external factors like transport.
