River levels have risen sharply across the country after warm weather began to melt winter snow. River levels rose to level two, emergency situation, at around half a dozen spots around the country, mostly in southern Moravia. Level three, danger level, was reached at the small border town of Podhradi u Znojma, on Monday afternoon. No damage was reported. The water level of the river Dyje there has tripled over the last days. Forecasters say the warm weather will cause snow on higher ground to melt over the next days with rain expected by the end of the week.
