Why It Matters
An Atlantic disturbance crosses Italy bringing meteorological instability and intense rainfall.
Widespread and heavy rainfall, local thunderstorms, wind and drop in temperatures. Tomorrow and Wednesday, Italy will be hit by a widespread Atlantic disturbance. The first signs can already be seen today, underlines Federico Brescia, meteorologist at iLMeteo.it, with "conditions of marked instability in the North-West and locally intense phenomena that will affect Western Liguria".
On Tuesday, the bad weather will mainly hit the North-West regions, and in particular Liguria and Piedmont, with continuous and abundant rain.
"By Wednesday afternoon - says Brescia - the overall accumulations could exceed 100-150 mm in the Savonese area". Not only that: with the progressive advancement of the front, rainfall will extend to almost the entire national territory. Particular attention will be paid to the Tyrrhenian sectors, Tuscany and Lazio first and foremost. The winds will move from the western and south-western quadrants: the intense Libeccio currents which will blow at over 40 km/h will be able to generate storm surges along the exposed coasts of Liguria and Tuscany with waves up to 3-4 meters high.
Finally, from Thursday, thanks to the bad weather, there will be a drop in minimum temperatures of around 2-4°C.
In detail: - Monday 19. In the North: light rain in Piedmont and Liguria. In the Center: rainy places on the coasts of Tuscany, sunnier elsewhere. In the South and on the Islands: instability on the Major Islands and on the Ionian sides.
- Tuesday 20. In the North: intense rain in the North-West (over 70-90 mm of accumulation in 24 hours). In the Centre: worsens by evening in Tuscany and Lazio. In the South and on the Islands: thunderstorms in Sardinia, more stable elsewhere.
- Wednesday 21. In the North: unstable with thunderstorms especially in eastern Liguria and middle/upper Triveneto. In the Center: showers and thunderstorms on the Tyrrhenian areas, better on the Adriatic. In the South: thunderstorms in Campania, widespread instability elsewhere.
Trend: new disturbed passage, but much weaker and faster expected between Friday 23rd and Saturday 24th.
