Overview
- Showers are expected to begin Tuesday night in Liguria di Levante, Lombardy and the Alps and to spread across the rest of the North on Wednesday.
- Meteorological services forecast a general temperature fall of about 6–8°C that will lower daytime highs from the mid-30s to the mid-to-high 20s across much of the country.
- The collision of cold air aloft with months of accumulated heat and unusually warm seas raises the risk of intense convective storms producing strong winds, hail and localized heavy rain.
- The perturbation should move from north to south, reaching central regions by Friday and the South over the weekend, and forecasters say the cooler, unsettled pattern could persist into mid-September though late-September heat remains possible.
- The change offers short-term relief for people and stressed systems after a summer that CNR and other analyses say may be the hottest on record in Italy, but it also brings acute hazards for agriculture, transport and flash flooding.
