Several areas across southern Finland were drenched by a storm on Tuesday night that brought more than half a month's worth of rainfall in just a couple of hours.
For example, Finland's southernmost mainland municipality of Hanko saw 42.7 mm of rainfall on Tuesday night, according to Yle meteorologist Nina Karusto. Normally, Hanko gets about 76 mm of rain during the entire month of October.
Average rainfall across southern Finland in October ranges from 60-80 mm, but some areas in the region recorded between 20-40 mm of rain during Tuesday's storm.
The precipitation system headed eastward during the day on Wednesday.
The Finnish Meteorological Institute has issued warnings on Wednesday and Thursday for potentially dangerous flood conditions in areas along the southern and southwest coast, including the regions of Uusimaa, Kymenlaakso and South Karelia.
Chillier conditions coming
However, the weather system's winds were not as powerful as expected. While there were some storm-strength gusts in sea areas by Helsinki and Porvoo, Tuesday night saw average wind speeds of around 18 m/s. Storm wind speeds range between 21-32 m/s.
There is a risk that some rivers in affected areas could flood, but the threat of widespread flooding is not anticipated, according to Karusto.
Meanwhile, Northern Lapland got a dusting of snow overnight, and the precipitation system is expected to move south towards North Ostrobothnia and Kainuu on Wednesday night.
Karusto said this might mean the first snow of the season in those areas. Additionally, cold air from the north is also headed in the same direction, so it will be chilly there, too.
Other parts of the country will be relatively cool too, with many areas seeing temperatures below 10 degrees Celsius. In Lapland, temperatures could drop below 5 degrees.
