Another heatwave will hit the south-west this week
An amber heat alert has been issued for the south-west of England as temperatures are expected to rise significantly for four days during a new heatwave.
The UK Health Service Agency (UKHSA) announced the warning, which will be effective from Wednesday at 08:00 BST until 12 July at 21:00.
BBC senior weather presenter Sara Thornton indicated that temperatures could remain around 30C (86F), approximately 10C (50F) above the average, for at least 10 days starting Wednesday.
Dr Agostinho Sousa, head of extreme events and health protection at UKHSA, stated that the anticipated health impacts are not expected to be as severe as those experienced during June's heatwave based on the current forecast. However, he emphasized that older adults and individuals with pre-existing health conditions remain at risk.
Rise in deaths could happen
This alert follows several heat warnings issued to the west during the June heatwave, including a red alert indicating a risk to life.
The UKHSA cautioned that an increase in deaths could occur, particularly among people aged 65 and over or those with underlying health issues.
Indoor environments may also become excessively hot, posing increased risks to vulnerable individuals living independently or in community and care homes.
Additionally, the agency warned of potential travel delays and a rise in water-related incidents such as drowning and cold-water shock.
Tropical nights
Thornton commented on the challenges posed by the previous heatwave, noting:
"In the last heatwave many of us not only struggled with the record-breaking daytime temperatures, but also with sleep-disrupting heat at night.
In the West we saw a run of four tropical nights, where temperatures don't fall below 20C (68F), combined with high humidity.
We have the potential to see one or two tropical nights again later this week, most likely on Thursday and Friday nights, but overall, this heatwave is not quite as warm by night.
Crucially, it's also nowhere near as humid, so you should be able to cool down more easily," she added.
Thornton also noted that this heatwave is expected to last longer than those experienced in May and June.
Take sensible precautions
Sousa highlighted the importance of taking precautions during the heatwave, stating:
"It is important for everyone to take sensible precautions while enjoying the sun.
Sustained periods of warm weather can result in serious negative health outcomes across the population," he said.
"If you have friends, family, or neighbours who are more vulnerable, it is important to check in on them and ensure they are aware of the forecast and are following the necessary advice," he added.
People can take simple steps such as staying hydrated and avoiding the sun during the hottest part of the day.
Keeping your home cool are effective ways to help keep yourself and others safe during periods of hot weather," he concluded.
