Orange Warnings in Slovenia as Overnight Storm Triggers Landslides

Slovenia's environmental agency, ARSO, issued an Orange Flooding Warning for the Vipava river valley and an Orange Wind Warning for the coast and south-west, ranking both at level 3 of 4 on its own warning scale, in force as of 08:09 UTC on Nov. 13, 2026, after heavy rain fell overnight across the country. The flooding warning covers the Vipava river basin; the wind warning covers the coast and the country's south-west, where, as of that same check, ARSO forecasts gusts of 100 to 120 km/h.

Regional notification centers logged 33 emergency call-outs overnight, RTV Slovenija reported, citing Slovenia's Administration for Civil Protection and Disaster Relief; firefighters from nine professional and 20 volunteer brigades mostly pumped rain and groundwater out of buildings, covered damaged roofs and placed sandbags. In Kromberk, in the municipality of Nova Gorica, a retaining wall collapsed onto a road after the ground became saturated. The heaviest rain fell at the Otlica weather station, which measured 72 millimeters, as of 08:09 UTC on Nov. 13, 2026, RTV Slovenija said.

The Vipava river was flooding, with its upper course beginning to recede and its lower course still rising, ARSO said in a social media post RTV Slovenija cited, current as of 08:09 UTC on Nov. 13, 2026; two smaller rivers, the Logaščica and the Gradaščica, were also flooding to a lesser extent and had begun to recede. Slovenia's Geological Survey called for attention to possible signs of landslides starting, especially in the country's west and southeast, because of the rain. Rain was forecast to taper off from the north through the evening of Friday, Nov. 13, 2026, while the coastal wind known as the burja was forecast to strengthen during the afternoon and evening of Friday, Nov. 13, 2026, with gusts of up to about 100 km/h in exposed areas before weakening late at night.
