Acqua alta
(high water) isn't an emergency - it's a tide reaching 110cm above normal
levels and normally happens four to six times a year, between November and April.
Acqua alta
may cause flooding in low-lying areas, but waters usually recede within
five hours.
To see if
acqua alta
is likely, check Venice's Centro Maree 48-hour tidal forecast at
www.comune.venezia.it
.
Alarms sound when
acqua alta
is expected to reach the city
within two to four hours:
›
One even tone
(up to 110cm above normal): Barely warrants pauses in happy-hour
conversation.
›
Two rising tones
(110 to 120cm): You might need
stivali di gomma
(rubber boots).
›
Three rising tones
(around 130cm): Check Centro Maree online to see where
pas-
sarelle
(gangplank walkways) are in use.
›
Four rising tones
(140cm and up): Businesses may close early.
