Heavy rain has caused flooding at Heathrow, leading to the suspension of Elizabeth Line services between Heathrow Terminal 4 and Terminals 2 and 3. Transport for London (TfL) confirmed the disruption early on Tuesday, June 23, as a severe heatwave continues to affect parts of the UK.
Service suspensions and delays
According to TfL's website, there is no service between Heathrow Terminals 2&3 and Heathrow Terminal 4 due to flooding caused by heavy rain. Additionally, a points failure at Southall is causing minor delays across the entire Elizabeth Line, with severe delays reported between Whitechapel and Shenfield.
The London Tramlink also experienced a suspension between Sandilands and Elmers End/Beckenham Junction due to flooding.
Extreme weather warnings
The Met Office has issued an amber warning for extreme heat on Tuesday, followed by a red weather warning on Thursday and Friday. Rail passengers across the UK have been advised to avoid non-essential travel, with refunds being offered for those affected.
On Monday, TfL warned of network delays, particularly on the Elizabeth Line and Overground. One X user reported intense rain and lightning in Ruislip, describing the storm as "something else" and noting flash flooding not seen in years.
