The report says the game is scheduled for Saturday at 5pm at Hard Rock Stadium, but the start time may not be entirely secure. Under the safety procedure cited in the update, play could be suspended for 30 minutes if lightning is recorded within eight miles of the stadium.
The danger may continue even after the heaviest rain has passed. Lightning can travel well beyond the main storm area, meaning officials could be forced to wait before allowing players and supporters back into exposed areas.
That would not necessarily mean a cancellation, but it could disrupt warm-ups, preparation and the rhythm of a knockout tie where concentration is vital.
Merrill explained that South Florida’s sea-breeze pattern can produce afternoon showers and thunderstorms, with storms potentially strengthening around the time of the match.
The conditions are also expected to be hot and humid, with the report forecasting temperatures around 33°C and a higher feels-like temperature. For players, that can make repeated sprints and recovery more difficult, particularly if the match is interrupted and restarted.
Supporters face their own concerns. The update advises anyone who hears thunder to seek shelter inside a sturdy building, rather than remaining in open stands or exposed areas. Hydration will also be important, with heat exhaustion a genuine risk in oppressive humidity.
England and Norway may have prepared for each other tactically, but neither side can control the skies. A delay could break momentum, alter pre-match routines and turn patience into a decisive part of the contest.
The next storyline will come when the teams arrive in Miami: whether the storm threat fades, or whether weather officials and match organisers become as important as the players before kick-off.
