Heathrow Warns Against Road Travel to Terminals 2 and 3 After Flooding

Heathrow Airport issued an urgent travel warning on Saturday, August 15, 2026, advising passengers not to travel by road to Terminals 2 and 3 due to severe flooding in the central terminal area. The incident has completely blocked road access, forcing major closures during one of the busiest periods of the summer school holidays.

Airport officials and emergency teams are on site investigating the cause of the flooding and assessing any potential damage to facilities. While the exact source has not been confirmed, officials are examining possibilities including a burst water main.
