The UK Health Security Agency (UKHSA) has issued an amber heat health alert for parts of the UK as temperatures are expected to soar over the bank holiday weekend.
The alerts – which mean significant impacts are likely across health and care services – cover the East Midlands, West Midlands, the east of England, London and the South East.
They are in place from 2pm on Friday until 5pm next Wednesday and replace less severe yellow alerts which were previously in place.
According to the UKHSA website, an amber heat health alert means there is likely to be “a rise in deaths, particularly among those aged 65 and over or with health conditions” and increased demand on all health and social care services.New yellow alerts have been issued for the north-east and north-west of England, Yorkshire and Humber and the south-west of England.
The less severe alert means significant impacts on health and social care services are possible.
This comes as the UK is forecast to see its hottest May day on record over the bank holiday weekend.
Temperatures are forecast to reach 33C in southern England and the Midlands on Monday — higher than the UK’s current May temperature record of 32.8C.
Highs of 28C are expected in parts of south-east England on Friday before climbing above 30C across swathes of England and Wales over the following days.
It means many areas will also be hotter than top European holiday spots including Mykonos, Marbella and Benidorm.
The London Fire Brigade (LFB) said on Friday people should be aware of the increased risk of fires – including wildfires – in hot and dry weather conditions.
Those who plan on throwing a barbecue party should be particularly careful about fire safety, LFB said.
“We know that barbecues will be very popular this weekend, so we’re sharing some simple safety tips that will help to prevent a fire ruining your bank holiday,” LFB Assistant Commissioner Paul McCourt said.
“If you’re having a barbecue at home, make sure it is positioned on level ground, and away from flammable materials like fences, sheds and trees.
“Please don’t have a barbecue on a balcony, or on decking, and please do keep children and pets away from barbecues.”
People should also take steps to minimise the risks of grass and wildfires, as they are often caused by human actions such as the disposing of cigarettes, LFB said.

“We had a wetter-than-usual winter, which allowed vegetation to grow, followed by one of the driest Aprils on record,” Mr McCourt said.
“As we head into a week of hot weather, the risk of wildfire is very real.”
LFB also urged caution around water as their figures show that 40% of water-related incidents occur between May and August.
“We know that the warmer weather can tempt people to cool off in rivers, reservoirs and lakes, but even in hot weather most inland water in London remains very cold, and can be below 16C,” Mr McCourt said.
“This can cause cold water shock and lead to drowning.
“Despite a calm surface, open water can have strong currents, hidden debris, slippery edges, and sudden drops in depth - all of which can be fatal.
“If you are planning to swim outdoors, only do so in designated areas, and ensure that lifeguards and safety equipment are present.
“If you see someone else in difficulty, don’t enter the water yourself,” Mr McCourt added.
“Call 999 and try to throw them something that floats.”
