An "orange alert" for storm and rain-flooding has been placed in effect since midday, the prefect of the Provence-Alpes-Cote d'Azur region, where the city of Marseille is located, said in a statement on social media.
"Rainfall could reach 70 to 90 mm in some areas and locally 120 mm in a few hours," the prefect said on Sunday.
"These weather forecasts raise fears of heavy rainfall across the region between 7 p.m. and 10 p.m., i.e. at the start and end of the match, which was expected to attract nearly 70,000 supporters to the Orange-Velodrome stadium."
The match will now kick off on Monday at 20:00 local time.
"The club informs its supporters that tickets purchased for the match scheduled for this evening will remain valid for the rescheduled match tomorrow," Marseille said.
