Britain on course for hottest day on record

Britain’s first-ever extreme heat warning is in effect for large parts of England as authorities prepare for record high temperatures that are already disrupting travel, health care and schools, according to AP.

The “red” alert will last throughout Monday and Tuesday when temperatures may reach 40ºC (104ºF) for the first time, posing a risk of serious illness and even death among healthy people, according to the UK Met Office, the country’s weather service. The highest temperature ever recorded in Britain is 38.7ºC (101.7ºF), a record set in 2019.

Much of Europe is baking in a heat-wave that has pushed temperatures into the mid-40s Celsius in some regions, with wildfires raging across tinder-dry countryside in Portugal, Spain and France.

"We've got a difficult 48 hours coming," Kit Malthouse, a minister in charge of government coordination, told the BBC.

London's Underground metro network imposed temporary speed restrictions on the network for Monday and Tuesday, meaning it would run a reduced service with journeys taking longer than normal. It urged commuters to only travel if essential, reported Reuters.

The national rail network also urged passengers to stay at home, and said some services - including a key route between northeastern England and London - would not run during parts of Tuesday.

Jake Kelly from Network Rail said he hoped normal operations would resume on Wednesday, when temperatures are forecast to fall, but that would depend on "the damage that the weather does to the infrastructure over the next couple of days".

Some schools were due to close earlier than usual on Monday.

The Health Security Agency (UKHSA) raised the heat health warning to Level 4 for England for Monday and Tuesday.

Britain' Meteorological Office defines a Level 4 alert as a national emergency, and is used when a heat-wave "is so severe and/or prolonged that its effects extend outside the health and social care system. At this level, illness and death may occur among the fit and healthy, and not just in high-risk groups."

The Met Office said "substantial" changes in working practices and daily routines would be required and there was a high risk of failure of heat-sensitive systems and equipment, potentially leading to localised loss of power, water or mobile phone services.

Malthouse said the government was prepared for the extreme weather and would seek to learn lessons from it.

"We definitely need to adapt the way we build buildings, the way we operate and look at some of our infrastructure in the light of what seems to be an increasing frequency of these kinds of events," he told the media.
