Flash floods are becoming a growing challenge across Europe. Copernicus helps local authorities increase their preparedness. In the Rosenheim district, Germany, mapping products identified warning times before inundation for individual buildings and estimated maximum flood depths across the area.

An incredibly well-timed Landsat 9 pass captured the effects of yesterday’s catastrophic glacier collapse near the Nepal–Tibet border. The event was so massive that it was detected by seismometers around the world.

🌧️ 15 mm på seks timer: ingen bemærker det. 15 mm på 30 minutter: det er et #skybrud. Samme mængde vand, vidt forskellig konsekvens. Forskellen er tempoet ⏱️ #Afløb er dimensioneret efter intensitet, ikke efter årsnedbør. Derfor kan en halv time gøre mere end en uges regn.

💧 Vand kommer tre steder fra: fra oven (#skybrud), fra neden (grundvand og kloak) og fra siden (hav, fjord, #vandløb). De føles ens, når man står i det. Men de har hver sin årsag og kræver hver sin løsning. Det er der, vi begynder.

This heatwave in Europe is insane. Over 10 days of beyond tropical nights (above 20C). No one here is prepared for this. Also, weather companies should by default publish pre 1990 averages alongside the forecast. Honestly, failure to do so is yet another kind of climate denial.
Weather forecast for my part of Switzerland, all days above 30, all nights above 20, for 10 days.
