In the latest heat spike, the UK Health Security Agency (UKHSA) has amber heat health alerts in place for the East Midlands, East of England, South East and London until Wednesday morning. There are also yellow heat health alerts for the North West, South West, West Midlands, and Yorkshire and The Humber, as the agency warns the latest high temperatures could put extra pressure on the NHS, with more vulnerable people likely to require medical treatment. But the South East will continue to see little in the way of desperately needed rain, the Met Office has warned. July was southern England’s driest month ever recorded, with the whole of Wales and half of England plunged into drought. In July, 19 counties across England recorded effectively no rainfall – 1mm or less – across the whole of the month, the Met Office figures show.
