Red Heat Warning Issued for England and Wales
A rare red weather warning for extreme heat has been issued for parts of England and Wales later this week, with temperatures potentially reaching 40C in some areas.
The Met Office warning covers London, parts of the Midlands, south-east Wales, and southern England, and is effective from 09:00 BST on Wednesday until 21:00 BST on Thursday.
Forecasters have indicated that the extreme heat will be intensified by high humidity levels, warning of "significant disruption" to daily life, including travel interruptions. Several schools have already announced plans to close early in response.
The Met Office has stated that the hot weather will have widespread health impacts, potentially causing serious illness and posing a danger to life.
Amber Warnings and Temperature Forecasts
Less severe amber weather warnings are also in place across much of southern and central England and most of Wales from Monday through to the end of Thursday.
In the areas expected to be worst affected, temperatures could reach up to 40C, with the peak of the heatwave anticipated on Wednesday and Thursday.
This would approach the UK's highest recorded temperature of 40.3C, set in Coningsby in July 2022, which was also the only previous occasion a red extreme heat weather warning was issued.
Temperatures are forecast to rise quickly on Monday, with a chance of thundery showers in some locations.
Highs of 37C are expected in southern England and 35C in south-east Wales on Tuesday.
Temperatures are then predicted to reach at least 39C on Wednesday and Thursday, with the possibility of exceeding this level.
During the heatwave, some areas may experience temperatures that do not fall below 21C or 22C overnight, resulting in so-called tropical nights.
Health Warnings and Preparations
The UK Health Security Agency (UKHSA) has issued its own red heat health warnings, marking only the second time such a warning related to heat has been issued.
The UKHSA warnings cover the West Midlands, East Midlands, South East, South West, London, and East of England, and will be in effect from 01:00 BST on Wednesday until 23:00 BST on Thursday.
Dr Agostinho Sousa, head of extreme events and health protection at UKHSA, has urged health and social care services across the country to prepare for the upcoming conditions.
"It is vitally important that people understand the risk posed by high temperatures like these, and take steps to keep themselves and their friends, families and neighbours safe," he said.
Early Signs of Disruption and School Responses
As temperatures began to rise over the weekend and into Monday, some disruptions have already emerged as the country prepares for the heatwave.
While the government does not typically advise school closures during hot weather, it recommends several measures to manage the conditions.
Several schools across England have implemented measures such as relaxing uniform rules and scheduling early closures over the coming days.
The National Association of Head Teachers (NAHT) has issued guidance to its members.
Paul Whiteman, the organisation's general secretary, said: "While there is no legal 'upper limit' for temperature in schools, (school leaders) will certainly be doing all they can to mitigate the effects of such high temperatures."
Safety Warnings and Water Usage
The National Fire Chiefs Council (NFCC) has urged the public to exercise caution around open water and outdoor spaces following several water-related deaths during the recent heatwave in May.
Chair Phil Garrigan said: "We are also asking people to be mindful of the impact their actions can have outdoors. Many people do not realise how easily a wildfire can start or how quickly it can spread."
South East Water has requested that residents use water only for essential purposes due to intense pressure on its network.
Travel Disruptions and Road Safety
Travel disruptions are expected to increase as temperatures rise, affecting both railways and roads.
On roads, the AA has announced that gritters will be deployed on some routes to address potential softening or stickiness of road surfaces caused by the heat.
Edmund King, the AA's president, advised drivers to reduce speed and avoid harsh braking or steering when encountering softened or damaged road surfaces.
Rod Dennis, road safety spokesperson at RAC, recommended that drivers in red warning areas avoid non-essential journeys if their vehicles lack effective air conditioning.
He warned that heat can put strain on vehicles and increases the potential for vehicle breakdowns.
Some Great Western Railway trains experienced delays or cancellations on Monday due to the heat, and forecasters have indicated that such disruptions may become more widespread across the rail network as the week continues.
Heatwave Origin and International Impact
The heatwave is spreading from continental Europe, where an intense hot spell has developed.
On Monday, two children were found dead in a vehicle in France in an incident the local state prosecutor described as "probably linked to the heatwave." Red warnings are currently in force in more than half of France's regions and across other parts of western and central Europe.
