Spring floods are expected to be small or at most ordinary – snowfall could still change the forecast
Spring floods in Finland are predicted to be smaller than usual, with certain areas experiencing significantly low water levels due to lack of snow.
The Finnish Environment Institute reports that spring floods this year are expected to be smaller or at most typical across many regions of Finland, particularly in the southern, western, and central parts of the country where snow levels are unusually low. This scenario indicates that the flood risks could be minimized this season, as observed by researcher Harri Myllyniemi, who points out that the melting temperatures and rainfall during melt season will also significantly affect the final flood extent.
In regions like Satakunta and Northern Ostrobothnia, the spring flood levels could be record low, attributed to the thin snow cover and gradual melting patterns. The Environment Institute notes that this low snow level occurs on average only once in every ten years in Satakunta, which is indicative of the unusual climate conditions present this year. Thus, the anticipation of ordinary or slight flooding could provide relief to local communities that have faced significant flooding challenges in prior years.
In Lapland, flood forecasting remains premature, as local ice conditions have yet to be determined. According to the Lapland ELY Centre's leading water management expert Niina Ka, further assessments will be necessary as the situation evolves. These forecasts indicate a cautious approach to monitoring spring flooding dynamics, reminding stakeholders of the potential changes that further snowfall or temperature fluctuations might bring to the overall flood outlook for the region.
