2021 Bosnia and Herzegovina floods

Between 4 and 11 November 2021, heavy rainfall resulted in widespread flash flooding in many places across Bosnia and Herzegovina. The Federal Hydrometereological Institute issued a red warning on 5 November 2021 for flooding. There was great material damage.

The first wave of floods started in the night of 4–5 November and caused many rivers to flood or have their levels significantly increased. Hundreds of objects were at least partially flooded. The settlement of Otes was hit the hardest, where fire cars were used to evacuate tens of people and sandbags placed to prevent houses from flooding. The rain was forecast to not completely stop until Monday, 8 November 2021. Many villages in Sarajevo Canton were submerged and the A1 motorway was closed. The waters were receding during 6 and 7 November, except in the city of Doboj, where there was a slight increase. A few unexploded bombs were found in previously flooded regions.
