all CZ waymarkers are probably OK :).
thanks for your prayer. i am fortunately far way off floods - the worst came to the very east of Czech republic. But as we see, it was really fast flood - during 1-2 hours of heavy rain have fallen 10-20 cm of water per m2 (it is veeeery much). and then at night came high flood water wave, that in 15 minutes raised small local streams water levels by 4 meters!
