Last hours of unstable weather before the storm. From tomorrow a bomb cyclone will break out in northern Italy bringing torrential rains and windstorms.

In the south, however, there will be yet another unseasonal heat wave.
This is what we learn from reading the latest weather maps since the cold currents entering our country will fuel an explosive cyclogenesis or bomb cyclone on the Ligurian Sea.
In practice, a low pressure area, located at mid-latitudes, sees the atmospheric pressure fall to its minimum baric level at a rate of at least one millibar (hPa) per hour for at least 24 hours. The phenomenon causes heavy rainfall and violent gusts of wind of over 140 km/h.
There is an alert for Sardinia and part of the Ligurian Sea, especially between eastern Liguria and upper Tuscany, where the risk of a powerful storm surge with waves up to 6 metres high is more than concrete between Friday 20th and the early hours of Saturday 21st.
The weather will worsen first in the North, where heavy rains and thunderstorms will arrive, then from Friday also in the Center. Violent storms cannot be ruled out at this time, especially in Eastern Liguria, upper Tuscany and Friuli Venezia Giulia.
But the cyclone will bring very hot winds of African origin that will hit the South and central Adriatic sectors, causing an increase in temperatures. The southern winds will intensify from Libeccio on the Tyrrhenian side and from Sirocco on the Adriatic side, with the possibility of some storm surges and the phenomenon of high water on the Venetian lagoon.
