Reposted by Patrick ErikssonMika Rantanen @mikarantane.bsky.social · 06/02/2026Breaking: Helsinki, Finland, has just recorded its lowest sea level on record, as a cold easterly flow and strong high pressure have pushed water out of the Baltic Sea. The observed minimum this morning was −93.5 cm below normal. The Helsinki tide gauge record goes back to 1904. 76623 0
Patrick Eriksson @pberiksson.bsky.social · 05/02/2026A justified concern indeed! At least the VTS monitoring is constantly watching the situation and on their toes. 010 0
Patrick Eriksson @pberiksson.bsky.social · 05/02/2026All Finnish icebreakers are busy assisting maritime traffic, and the #seaice on the #BalticSea continues to expand. If the Bothnian Sea becomes fully ice-covered this winter, it would be the first time since February 2011. Follow the daily ice situation at: en.ilmatieteenlaitos.fi/ice-conditio... 1195 0
Patrick Eriksson @pberiksson.bsky.social · 24/01/2026Drawing ice charts is fun, sometimes the ice polygons take some nice shapes, like this cute Ice Fox sitting on the Oulu fairway on today's #BalticSea #icechart.🦊😍 You can access the @ilmatieteenlaitos.fi ice chart at en.ilmatieteenlaitos.fi/ice-conditions 000 0

Patrick Eriksson @pberiksson.bsky.social · 09/12/2024This winter's daily Baltic Sea #icechart :ing, done jointly by the Finnish and Swedish ice services, started today. The freeze-up is well under way in the Bay of Bothnia and the #icebreaking operation will quite likely start within a few weeks. 110 0
Patrick Eriksson @pberiksson.bsky.social · 06/12/2024The long-awaited #Sentinel-1C satellite 🛰️ is now in orbit! So excited to pipeline its data to our sea-ice monitoring and the #BalticSea #icebreaking as soon as possible. www.esa.int/Newsroom/Pre...esa.intDouble win for Europe: Sentinel-1C and Vega-C take to the skies 000 0

Patrick Eriksson @pberiksson.bsky.social · 18/11/2024When looking a few days ahead, we have to look at probabilities caused by diverging forecasts. Here we chose to change the weighing of forecasts with different sensitivity to weather forcing and local conditions. The coming runs will narrow things down a lot in the coming couple of days. 010 0
Patrick Eriksson @pberiksson.bsky.social · 18/11/2024And just as you posted that update, the re-evaluation of the forecasts forced us at #FMI_OceanographicServices to downgrade back. Unusually high waves (close to 5 m) in the Bay of Bothnia are still possible, however. 110 0
