Spring flood event in central Bulgaria (22–24 May 2026) driven by orographic rainfall and snowmelt in Maritsa River basin; widespread inundation and displacement risk.
🌊 OPEN LIVE 3D WEATHER ALERTSA significant flood event struck central Bulgaria from 22–24 May 2026, centred near the coordinates 42.816°N, 24.907°E in the Maritsa River basin region. The Green Flood, as designated by emergency responders, brought intense precipitation and river overflow that displaced communities and threatened critical infrastructure across multiple municipalities. The GDACS alert system flagged this as a high-severity hydrometeorological hazard with immediate risk to populated lowlands and agricultural zones along the Maritsa and its tributaries.
Bulgaria's spring flood season is driven by two competing factors: snowmelt from the Rhodope and Balkan mountain ranges combined with frontal rainfall systems moving north from the Mediterranean. During late May, atmospheric circulation patterns can stall warm, moisture-laden air masses over the region, triggering sustained precipitation over already-saturated soils. The Maritsa River basin, one of southeastern Europe's largest, acts as a natural funnel—tributary flows from higher elevations rapidly concentrate in valley floors, creating flash-flood conditions within hours of intense rainfall.
Pandita Data integrates real-time NOAA precipitation radar, USGS streamflow gauges, and Sentinel-1 synthetic aperture radar to map water surface extent and inundation patterns. Satellite imagery reveals flooded areas as dark zones against normal terrain, while stream-height data confirms river stage and discharge rates exceeding 10-year recurrence intervals at key monitoring stations.
Depth Risk: Slow-moving floodwater in populated areas can exceed 1–2 m; fast-moving channels pose drowning and vehicle entrapment hazards. Duration: Inundation typically persists 3–7 days after peak flow. Secondary Hazards: Landslides on saturated slopes, contamination of water supplies, crop and livestock loss.
