London is bracing for its hottest day of the year so far, with temperatures expected to reach 34C on Tuesday, as the Met Office issues a heat health warning and train operators warn of potential delays.
Temperature Record Expected
The mercury is forecast to climb to 34C in the capital, surpassing the previous high of 32.2C recorded in June. The Met Office has issued a Level 2 heat health warning for London and the South East, urging people to stay hydrated and avoid the sun during peak hours.
According to the Met Office, the hot weather is due to a plume of warm air from the Continent, with temperatures expected to remain high overnight, offering little respite.
Train Delays and Speed Restrictions
Train operators, including Thameslink and Great Northern, have warned of potential delays and cancellations due to speed restrictions imposed on tracks to prevent buckling. Network Rail said trains will run at reduced speeds of up to 20mph on some routes, adding up to 30 minutes to journey times.
A spokesperson for Network Rail said: 'We're doing everything we can to keep passengers moving safely during this hot weather, but speed restrictions are necessary to avoid track buckling.'
Health Advice for Londoners
Public Health England (PHE) has issued advice for the public, particularly the elderly and those with underlying health conditions, to keep cool and drink plenty of water. The London Ambulance Service has also prepared for an increase in calls related to heat exhaustion and dehydration.
Dr. Owen Landeg, scientific and technical lead at PHE, said: 'While many people enjoy the hot weather, it's important to take care of yourself and others. Look out for those who may be vulnerable to the heat, such as older people and those with long-term health conditions.'
Cooling Centres and Water Stations
London boroughs have set up cooling centres in libraries and community centres, and water stations are being provided at major transport hubs, including King's Cross and Victoria stations. The Mayor of London, Sadiq Khan, has activated the Severe Weather Emergency Protocol to ensure rough sleepers are offered shelter.
The hot weather is expected to peak on Tuesday before a cold front moves in from the west on Wednesday, bringing thunderstorms and cooler temperatures.
