The path of the Mediterranean surface and Upper Level Lows exactly follows that of a classical 5b low, from the Mediterranean over Hungary and E. Austria further to the North across Slovakia and the Czech Republic to Poland. As a consequence of this path and taking into account Stau effects at the mountains, severe weather can be expected over the whole of Austria and surrounding countries. This catastrophic case led to a disastrous flood situation effecting not only the countries mentioned above, but also much of eastern Germany.
