France’s group-stage clash with Iraq was delayed mid-match due to lightning in the area as Fifa’s World Cup 2026 weather protocol was actioned.After heavy rain brought about the wettest half of football seen at this World Cup so far, the storm in the Philadelphia area escalated at half-time to lightning, meaning players and fans were forced inside.Fifa is adhering to rules set by local authorities during the tournament, with the National Oceanic and Atmospheric Administration (NOAA) saying that if any lightning strike is detected within eight miles of a stadium the game has to be stopped.This sparks a countdown of 15 minutes, which resets every time another lightning strike happens.

While a scorching New York City, with temperatures in the mid-30s during the opening days of the tournament, experienced heavy rainfall, thunder and lightning less than 24 hours before Brazil face Morocco in New Jersey.That was a scenario seen several times during last year’s Club World Cup in the US, with six matches halted due to electrical storms.That included an encounter between Chelsea and Benfica which kicked off at 4.38pm local time and eventually finished four hours and 38 minutes after it had begun.A warning for lightning strikes appears on the big screen as heavy rain falls prior to the International Friendly match between England and Costa Rica at Inter&Co Stadium (The FA via Getty Images)Stadiums in the Gulf Coast area and south east of the United States are likeliest to come under threat from thunderstorms, with Fifa addressing each match on a case-by-case basis if play is halted.Issues could potentially arise if storms hit during the final round of group-stage games. The kick-off times of the two games in each group are synchronised to avoid affording an advantage to any nation by knowing what they need to do, although that may be unavoidable under such circumstances as a weather delay.Were conditions sufficiently dangerous to force an abandonment, World Cup regulations state that the game would be played on a future date, restarting in the same minute as it was paused, with the remaining minutes played.
