After a breather of barely several days, new flood concerns are emerging again in central Europe as many victims of the May flooding haven't yet managed to move back into their damaged homes.

Hungary is expecting five days of rain, thunderstorms and strong winds. Due to heavy rainfall, a village in western Hungary was sealed off by the police and traffic was diverted or stopped on several roads as mud and fallen trees block traffic.

A newly completed section of the M6 highway - connecting the capital city Budapest with the southern city Pecs - caved in as the water washed away the ground under the street.

Sand bags and pumps, barely dried after the previous flood a week earlier, are once again in use in several counties across the country. Drainages are still full and the soil can't to take any more water. One region reported six times as much rainfall in May than usually at this time of year, making it a very wet beginning of the summer in Hungary.

In southern Poland, heavy and prolonged rains are expected, with water levels feared rising again, mostly in the Vistula River that in May turned entire towns into lakes. Poland estimates the flood damage so far at more than €2 billion.
