Hot in Italy where summer has exploded with temperatures around 30 degrees. Tomorrow, Saturday 8 June, the yellow alert will be triggered (alert level 1, meteorological conditions that do not pose a risk to the health of the population) in Rome and in 5 other cities: Bologna, Campobasso, Frosinone, Latina and Perugia. This was communicated by the Ministry of Health’s heat wave bulletin which prepares daily reports for 27 cities, with 24, 48 and 72 hour forecasts.
Alert level 1 suggests “taking care of elderly relatives or neighbors who live alone” and reporting “any situations that require intervention to the social and health services”.
Next week Italy divided in two
The ‘taste’ of heat will be the prelude to a week which will offer an extreme weather scenario, with Italy being substantially divided in two: on the one hand thunderstorms, even violent ones and with the risk of hail, on the other the African heat, with temperatures approaching 40 degrees.
According to the latest updates from Central Europe, as early as Monday 10 June a deep depression, driven by polar currents, will rapidly cross central-northern Europe, and then plunge into the Mediterranean basin directly from the Rhone Gate.
Thunderstorms and hail
Due to the impetuous entry of unstable air at high altitude, extreme phenomena at a local level cannot be ruled out, such as cloudbursts and hailstorms, given the strong contrasts that will be created in our country.
In particular with this type of configuration they will be the northern regions at greatest risk of precipitation, with possible cumulative rainfall of up to over 100 mm (the equivalent of all the rain of the month concentrated in a few hours); this situation could give rise to local flooding or landslides along the slopes, similar to what we have seen in recent weeks.
Hot in the south
However, bad weather represents only one side of the coin. Due to the anti-clockwise rotation of the currents around the minimum depression, the simultaneous rise of a very hot air mass of sub-tropical origin is foreseeable, directly from the Sahara desert, which within the African anticyclone Scipione will expand on all the central-southern regions. Temperatures far above the average for the period are expected in these sectors with maximum peaks reaching around 38-40°C in Sicily, Sardinia, Calabria and Puglia.
The key phase of this exceptional heat wave is expected between Monday 10th, Tuesday 11th and Wednesday 12th June as we can see from the map below. All eyes then turned to the second part of the week: between In fact, the passage of a second storm front is expected on Wednesday 12th and Thursday 13th June.
More bad weather from Wednesday
According to the latest updates, Italy will find itself right in the middle of a battlefield between colder and more unstable currents driven by a cyclone descending from Northern Europe and extreme heat rising from Africa.
Precisely the first summer-like heat transported by the African anticyclone will provide additional fuel for the genesis of violent phenomena. A potentially explosive mix from an atmospheric point of view. Once again, with this type of dynamic, the Northern regions will be most exposed to extreme weather events such as storms and hailstorms; for details and any Civil Protection alerts we will have to wait a few more days.
