Austrian authorities have closed sections of the Danube to shipping traffic over the elevated water levels along the vital waterway, according to reports in local media.
The Croatian Meteorological and Hydrological Service has warned the river could experience an “extremely rare” water increase – and confirmed plans are in place to put up flood barriers if necessary.
In Italy, the country’s National Civil Protection Service has also issued yellow alerts for nearly 50 regions tomorrow, warning there is a risk of storms, landslides and floods.
Prof Hannah Cloke, a meteorologist from the University of Reading, told the BBC that river levels had peaked in most of the smaller, upland rivers of flood-hit eastern Europe.
“Some bigger rivers, such as the Danube and Oder, are still rising in parts and will not start to go down again until late Tuesday or Wednesday, and will remain much higher than normal,” she added.
BBC Weather forecasts are pinpointing the Emilia-Romagna and Marche regions as areas of greatest concern.
The region could see one or two months’ worth of rainfall in the next three days alone, and there are major concerns over the prospect of flooding.
Firefighters in Pescara, Abruzzo say they have already received more than 200 calls for help after heavy rainfall triggered flooding.
In Romania, more rain is forecast in the eastern Carpathians, endangering towns and villages in Galati and Vaslui counties, which have already been hard hit.
