The flood situation in Lapland will remain calm for the next few days - major flooding still a risk in June (Lapland)

Information provided by the ELY Centre for Lapland and the Flood Centre

Lapland's rivers are not likely to cause major floods in the next few days as cool weather has caused snow to melt more slowly than usually. There is still a risk of major flooding at the beginning of June; after this cold spell, temperatures can rise significantly faster than anticipated which means that continuous snow melt might rapidly increase river flow. If warmer weather is accompanied by heavy rainfall, the situation will become serious. More information will be given on weather forecasts over the next few weeks.

The timing of the flood peaks in the large rivers of Lapland is still predicted to be early June. The Simojoki area is an exception; there the time of the heaviest flow is forecast after mid-May. In other parts of Lapland, flood peaks can already occur at the end of May if temperatures start to rise significantly faster than anticipated.

Unprecedented floods are possible in almost all waters in Lapland. The most vulnerable areas are Kittilä and Rovaniemi in the Kemijoki river basin and Pello in the Tornionjoki-Muonionjoki river basin. In these areas, flooding is expected to exceed the damage limit.

According to the most recent water system forecast, the snow will melt over a longer period of time than usually which slightly reduces the risk of major flooding. In Southern Lapland, the snow layer has thinned in early May but in other parts of Lapland, levels of water equivalent of snow remain exceptionally high.

In Lapland, Simojoki and the river areas in the lower and middle parts of Kemijoki have already almost totally lost ice. In the Tornionjoki and Ivalojoki streams, long stretches have already melted. The risk of ice jams is assessed to be low as the slowly progressing spring and gradually strengthening water flow significantly weaken the remaining ice.

The next flood report will be issued in the week 21, and information on the flood situation will be given on multiple channels including Twitter. You can find the flood forecast and warnings map on the national website. Forecasts are updated every few hours.
