October Weather in Italy - Likelihood of Acqua Alta in Venice

We are now close enough to our grand voyage that weather predictions are available -- yeah!  Predictions range with a high of 70 and low of 50 in each of the cities and chances for scattered showers and thunderstorms, which means the Daybreak Hugheses will be bringing jackets and umbrellas but no real cold weather clothes.

Additionally, Venice has been experiencing scattered showers throughout the week and, with showers the likelihood of Acqua Alta increases.  Venice for You has a page that predicts the likelihood of flooding for any given day and I'll be watching this site over the next two weeks. Currently, Venice is experiencing intense tides which means that the water level is between 90 and 100 cm above standard sea level.  At 100 cm up to 5% of the city may be flooded for some portion of the day. If the forecast predicts that the water levels may go above 120 cm "very intense" the Venetians set out wooden planks for easier transport around the city.

Even with a chance of light showers, it looks like we should have mild weather, perfect for a trip sure to include a lot of schlepping.
