A short spell of warm weather in early November is not unusual in Italy – it’s referred to as a ‘St Martin’s summer’ – but this year it has lasted around a month in many parts of the country.
The mild autumn weather is now set to come to an abrupt end as a wave of cyclones will move in from the Atlantic this week, said IlMeteo.it director and meteorologist Antonio Sanò in a forecast on Monday.
The north-west of Italy will see rain on Monday and snow at high altitudes, while showers are expected in central regions.
Weather elsewhere will be changeable, forecasts said, before stormy weather moves to the centre-south by the middle of the week.

Conditions are expected to be milder on Thursday before a second cyclone moves in on Friday and Saturday, bringing heavy rain and scattered local thunderstorms to much of the country, Sanò said.

The late arrival of stormy autumn weather will bring temperatures back down to seasonal averages – though sea temperatures remain unusually high, Sanò warned.
This difference in temperatures, meteorologists explain, creates heavy rain clouds bringing the risk of sudden bursts of extreme rainfall; a phenomenon known in Italian as a bomba d’acqua, or ‘water bomb’, which often causes flash flooding.

Experts say climate change is responsible for changing temperatures which are boosting the intensity and frequency of ‘extreme weather events’ such as floods.
The number of such events in Italy, including droughts, storms, floods, hailstorms, strong winds and tornadoes, has already been 42 percent higher in 2022 so far than last year.
