Emergency services in Helsinki's Kluuvikatu after a torrential downpour left dozens of sites flooded.

Emergency services were kept busy well into the night after a heavy thundershower dumped up to two centimetres of water in central Helsinki on Thursday.

The Meteorological Institute said Thursday evening's precipitation represented a third of an average July's rain.

Fire brigades were called to dozens of sites, with basements and lift shafts flooded and the rain triggering automatic fire alarms.

Traffic was also affected.
