Russia's weather officials warned that a powerful summer storm was expected in Moscow on Saturday afternoon, with gusts of winds reaching over 20 meters (65.6 feet) per second and possibly forming squalls.
FIFA fan zone Vorobyovy Gory (Sparrow Hills) was closed on Saturday afternoon due to the weather warning, with officials also closing Moscow's zoo and the VDNH permanent trade show. Owners of restaurants and cafes were instructed to close their outdoor seating areas.
Citizens should also brace for torrential downpours and hail, according to the country's official weather authority, the Hydro-meteorological Center.
