Thousands of passengers traveling through the UK’s busiest airport faced severe disruption as severe thunderstorms swept across southern England, forcing airlines and air traffic controllers to postpone hundreds of flights at Heathrow and Gatwick.The Met Office has issued a yellow thunderstorm warning covering much of southern England, warning that heavy rain, lightning, hail and flash flooding could affect traffic throughout the day. The bad weather forced planes to wait on the ground and in a holding pattern while air traffic controllers reduced airport capacity to ensure passenger safety.
Flight delays at Heathrow and Gatwick airports
Flight tracking data shows hundreds of flight departures and arrivals heathrow airport London Gatwick Airport is experiencing delays as storms sweep through the area.The temporary air traffic restrictions are in place because thunderstorms reduce the amount of airspace that controllers can safely use, according to the National Air Traffic Service (NATS). During bad weather, planes must stay farther apart, reducing the number of flights taking off and landing per hour.NATS said in a statement: “Thunderstorms in southern England are reducing available airspace for aircraft. Safety remains our priority and temporary traffic management measures are required.”The airport operator advised passengers to check directly with airlines before traveling and warned delays could last throughout the day as planes and crews gradually return to normal.
Met Office weather warnings
The Met Office has warned that thunderstorms could bring heavy downpours, frequent lightning, hail and gusty winds, disrupting travel across southern England.Forecasters said some areas could see 20-40mm of rain in the short term, with higher amounts possible in isolated areas where the storm is slow-moving.In addition to aviation disruptions, the weather agency warned:
- Localized flash floods.
- Difficult driving conditions.
- Temporary road closures.
- Railway services delayed.
- Power outages are possible in remote areas.
Meteorologists explained that the storm formed when very warm, moist air moved across the UK, creating unstable atmospheric conditions that caused severe thunderstorms to form quickly.
Passengers face waits at UK airports
Delays quickly emerged on departure boards across Heathrow and Gatwick terminals as passengers awaited revised departure times.Many inbound planes were also forced into holding mode before landing, causing knock-on effects throughout the day. Aviation experts note that even relatively short weather-related disruptions can take hours to restore as aircraft, crews and airport operations are displaced across the network.Several airlines advised customers to monitor flight status updates through their websites and mobile apps, while airport authorities encouraged travelers to allow extra travel time.
Will flights return to normal?
Forecasters expected the thunderstorms to fade away and airport operations to resume later in the day. However, aviation experts warned that delays are likely to continue even if skies clear as airlines take time to redeploy aircraft and crews.The Met Office said further showers and localized thunderstorms were still possible in parts of England, meaning passengers should continue to check weather forecasts and airline updates before traveling.For thousands of holidaymakers and business travelers, the storm was another reminder of how quickly severe summer weather can disrupt one of Europe’s busiest aviation networks.
