Emergency services have raised concerns about the heightened risk of wildfires in anticipation of an upcoming heatwave in the UK, with temperatures expected to soar to 32C in London this weekend.

Authorities have advised the public to check on elderly individuals and those with underlying health conditions as meteorologists anticipate a surge in temperatures that will peak over the weekend before subsiding early next week.

Most areas in southern England are set to experience temperatures exceeding the heatwave threshold, defined as reaching a specific temperature for three consecutive days, by the upcoming weekend.

In London, where the threshold stands at 28C, temperatures are projected to reach 29C on Thursday, 31C on Friday, and a scorching 32C on Saturday.

The heat will then extend northwards, with Manchester and Newcastle also expected to bask in temperatures in the late 20s by the weekend.

The Met Office has indicated that several locations are likely to surpass 30C on Saturday, marking the highest temperatures recorded so far this year.

Tony Wisson, deputy chief meteorologist at the Met Office, stated, "Over the next few days, stable weather conditions and abundant sunshine will lead to a gradual rise in temperatures. As we progress towards the end of the week, temperatures will climb even higher as winds shift to a southerly direction, drawing warmer air from continental Europe across the UK."

While the warmest temperatures are anticipated in London and eastern England, heatwave thresholds could be met across much of the Midlands, low-lying regions adjacent to the Peak District, and certain parts of east Wales by Saturday.

Concurrently, the London Fire Brigade has issued a cautionary notice regarding wildfires in light of the prolonged hot spell and following one of the driest spring seasons on record.

Charlie Pugsley, deputy commissioner for operational policy, prevention, and protection, emphasized the heightened risk of grass fires during extended periods of hot and dry weather, particularly when the grass is extremely dry and susceptible to rapid fire spread. Pugsley commended the efforts of local councils in implementing key measures, such as creating fire breaks, to mitigate the risk.

The Environment Agency declared a drought in Yorkshire last week, while the north-west of England entered drought status in the previous month. Concerns are also being raised about the impact of the heat on individuals with health vulnerabilities, prompting the UK Health Security Agency to issue its first yellow heat-health alert of the year last week to urge health and social care services to make necessary preparations.

Caroline Abrahams, director of Age UK, highlighted the importance of older individuals taking precautions as temperatures rise, especially those with chronic health conditions. She advised them to avoid direct sunlight, stay hydrated, and schedule outdoor activities such as walks, shopping, or gardening before or after the hottest part of the day, typically between 11am and 3pm. Abrahams also recommended taking steps to keep homes cool by minimizing exposure to hot air and maximizing circulation of cool air.
