Jurre:
Venice floods as forecasts fail to predict extent of high tide
The barriers have been raised tonight, and will be in use through the whole week because of exceptional
acque alte! It seems that the unpredictability of the tide was given by strong winds, together with swollen rivers. It has been raining and snowing unabatedly on all Northern Italy these last days.
Well, the MOSE (the barrier system for flood prevention) is still in an experimental phase, so they'll have to tweak some parameters.
