Jérôme Gautheret: Right now, the water level has risen to 153 cm, according to official figures. The recession begins in a few minutes. But there is some wind, and the coming days should be calmer. A strong breeze is announced for Sunday, but the general water level should drop slightly. So it looks like the worst is over, at least for the next few days. The "season" of acqua alta usually runs from mid-October to the end of April.
