This weekend’s summer storm ‘Kiira’ caused electricity blackouts, travel disruption and damage across south and east Finland.
But how did the storm get her name?
Meteorologists at the Finnish Meteorological Institute give a weather system a name if it is particularly strong, or if the conditions are expected to cause significant damage.
The storm is given an un-used name based on the date in Helsinki University’s name-day Almanac. Saturday was already Klaara’s name day, so an unused name, Kiira, was chosen instead.
If the name has already been used, then a serial number or year can also be added.
Meteorologists give storm systems names to help attract attention, and make the public more aware of the problems that could be forecast.
