Heavy rains are coming, alert in Campania

According to forecasts, the next few days will bring new heavy rains especially to the centre-south and therefore the alert for Campania remains high. Another low pressure cyclone will enter the field between Tuesday and Wednesday and is expected to bring heavy rains to the same area already affected, i.e. in the centre-south and therefore also in Campania (ANSA)

The perturbation phase that hit Italy with phenomena of intense rainfall such as those that helped to determine the strong landslide in Ischia, which caused deaths and missing persons, has not yet ended.

According to forecasts, the next few days will bring new heavy rains especially to the centre-south and therefore the alert for

Campania

remains high .

Meteorologist Sante Laviola, from the Institute of Atmospheric and Climate Sciences of the National Research Council, in fact warns that a new phase of low pressure is on the way with thunderstorms.

"What brought heavy rains in the last few days to the centre-south and to Ischia, giving rise to yesterday's landslide - Laviola points out to ANSA - was a low pressure cyclone located in the center of the Mediterranean. Now it should be noted that it is another low pressure cyclone is arriving, which will enter the field between Tuesday and Wednesday and is expected to bring heavy rains to the same area already affected, i.e. to the central-south and therefore also to Campania".

These are seasonal phenomena but to explain the particular intensity of these events, the expert clarifies, "it is also the particularly hot season from which we come. The Mediterranean is in fact extremely hot, reaching temperatures above the average, and this brings important effects because the clash of currents at different temperatures on a warm sea causes much more intense thunderstorms".

The Mediterranean, he says, "is a bit like water that boils and supplies humidity, or rather water and energy, to storm phenomena".

The higher temperature of this sea, which has increased over the years also as a result of global warming, has therefore made the central-southern area more at risk of extreme rainfall.

The demonstration also comes from a study just published by the Cnr which demonstrates, explains the meteorologist, how in the last 22 years the storm phenomena in the autumn period from September to November have moved from Northern Italy to the Centre-South of the Mediterranean basin, and this precisely due to the increased warming of the sea.

Regions such as Campania, Puglia, Calabria and Sicily, therefore, "being included in this area, are more subject to strong storms in this autumn period".

But monitoring has intensified these days because this is also the season with the greatest probability of another extreme phenomenon, that of the so-called

Mediterranean hurricanes

, or swirls of air that take on tropical characteristics with heavy rains and winds.

"They are expected a couple of days in advance and we are studying whether the overheating of the Mediterranean could determine an influence in terms of intensification of these events as well. At the moment there are no forecasts of imminent hurricanes in the Mediterranean basin but this too - he concludes Laviola - is a variable to be monitored carefully".
