Health authorities have issued the first heat-health alert of the year for six regions in the UK, in anticipation of a surge in temperatures. Experts have warned that high temperatures on Friday

and throughout the weekend could have an impact on individuals over the age of 65 and those with pre-existing health conditions.

The alert, spanning 72 hours from 9 am on Friday, applies to London, the East Midlands, West Midlands, East of England, the South East, and the South West. While London is expected to reach a high of 24°C on Saturday, "thundery showers" are also predicted. The warmest day is anticipated to be Saturday, with temperatures expected to reach 27°C or 28°C, and a slight possibility of hitting 29°C in areas north of London.

The UK Health Security Agency (UKHSA) has highlighted the potential impact on the health and social care sector if the forecasted temperatures are realized. The agency has urged Londoners to check on vulnerable family members, friends, and neighbors who may be at a higher risk of health issues during the hot weather.

The UKHSA recommends that those at risk should avoid sun exposure from 11 am to 3 pm, when temperatures are expected to peak. Dr. Agostinho Sousa, Head of Extreme Events and Health Protection at the UK Health Security Agency, emphasized the importance of staying hydrated and cool while enjoying the sun during the upcoming period of hot weather. He specifically mentioned the increased vulnerability of individuals over 65 or those with respiratory and cardiovascular diseases.

Last year's summer heatwave in the UK resulted in 3,200 more deaths compared to the five-year average, with temperatures surpassing 40°C in the capital for the first time ever. The extreme heat also led to several large wildfires in London, making it the busiest day for the London Fire Brigade since World War II. The Office for National Statistics (ONS) reported an additional 3,271 fatalities during the extended period of extreme heat throughout June, July, and August 2022.

Dan Harris, Deputy Chief Meteorologist at the Met Office, mentioned that temperatures would rise later in the week and over the weekend, with warm air being drawn in from the south. Some parts of England could experience temperatures peaking around 30°C, remaining well above average overnight. Alongside the rising temperatures, there is an increased likelihood of potentially heavy and thundery showers, which could cause localized disruptions from late Friday and into the weekend. However, exact details cannot be determined this far in advance. Photo by Stacey Harris, Wikimedia commons.
