Britain is heading into its fourth heatwave of the summer, with the Met Office forecasting that temperatures will climb above 30C across much of England and Wales from Monday and peak at about 34C (93F) in the south Midlands on Tuesday. The UK Health Security Agency has issued yellow heat-health alerts for most of England, excluding the far north, from Monday through Wednesday. The warnings advise the National Health Service and social-care providers to prepare for increased demand as vulnerable groups face heightened risks from prolonged high temperatures. The hot spell follows last week’s Storm Floris and is being driven by warm air drawn north from continental Europe. While England and Wales will see the highest values, Scotland and Northern Ireland are expected to remain cooler at 23–25C, with outbreaks of rain. Forecasters add that scattered heavy or thundery showers and elevated pollen levels are possible before cooler Atlantic air arrives later in the week.
