Britons are facing an imminent period of sweltering heat that is expected to persist into the following week, as cautioned by the UK government. The UK Health Security Agency (UKHSA) has raised amber health alerts for the ongoing heatwave, surpassing the severity of the previous one in May. London, the south-east, south-west, and east of England are regions where millions of residents are now under the health alerts, effective until 8pm on Tuesday, June 23.
The amber alert signifies the likelihood of significant impacts on health and social care services due to the soaring temperatures, leading to an increased risk of fatalities, especially among individuals aged 65 and above or with underlying health conditions. Additionally, there could be repercussions on younger age groups, as highlighted by the agency.
The workforce’s capacity to deliver services in the affected areas may be compromised due to the escalating temperatures, anticipated to reach the mid-30s. The east and west midlands are also under yellow health alerts for heat, indicating potential service disruptions due to the intense heat.
These government warnings coincide with forecasts indicating the approach of a high-pressure system that will bring elevated temperatures well above the June average across much of the country. Temperatures are projected to climb into the high 20s Celsius widely, with the possibility of reaching 32C in southern England on Sunday and potentially exceeding 34C on Monday. As the heat intensifies, humidity levels will rise, increasing the likelihood of thunderstorms.
Meteorologist Honor Criswick from the Met Office noted the difference in humidity levels compared to the last heatwave, emphasizing the increased discomfort due to higher humidity. The elevated humidity levels also raise the potential for thunderstorms, particularly in central and southern regions of England.
The duration of the heatwave remains uncertain, but it is expected to persist over the weekend and into the early part of the following week. The previous record-breaking heatwave in May saw temperatures soar to historic levels, meeting the criteria for a heatwave based on consecutive days with temperatures exceeding the threshold.
The UKHSA heat health alerts also emphasize the risks of water-related incidents, including cold-water shock and drowning. The Mirror’s ‘Save Lives for Sam’ campaign was launched in response to the alarming number of fatalities during water-related incidents, advocating for measures to prevent such tragedies and save young lives.
As people head to coastal areas in the coming days, it is important to note that sea-surface temperatures may not be as warm as during mid-summer, as highlighted by the Met Office. National Water Safety Partner at the RNLI, Samantha Hughes, stressed the importance of awareness regarding cold water shock and drowning risks, offering advice on water safety measures like floating to survive in case of distress. Additionally, she recommended choosing lifeguarded beaches and following safety guidelines when engaging in water activities.
