A strong low pressure system will hit Europe on the autumnal equinox, extending to four Arab countries.

Arab Weather - The latest advanced computer outputs from the Arab Weather Regional Center indicate that a cold air mass is rushing towards southern Europe, leading to the formation of a multi-front low pressure system characterized by high atmospheric activity on the day of the autumnal equinox, which falls on Monday, September 22, 2025. Its impact will extend to four Arab countries.

A highly active low pressure system is affecting southwestern Europe.

Experts at the Arab Weather Center said that the undulation of the polar jet stream will lead to a cold air mass rushing towards southwestern Europe, causing the formation of a low-pressure system that will affect several countries in central and southwestern Europe, including Italy, France, and neighboring countries. The low-pressure system will be accompanied by several weather phenomena, including the formation of dense thunderclouds laden with heavy rain, severe thunderstorms, and exceptional hailstorms with large pellets.

Snow is also expected to fall on the high mountain peaks, especially in the Alps, and this may be the heaviest snow since the beginning of autumn.

The low pressure system intensifies as it moves eastward, affecting four Arab countries.

According to weather maps, the depression is moving in a southeasterly direction, and with the cold air crossing the warm surface waters of the Mediterranean Sea and the extension of tropical humidity, the weather activity will intensify strongly in the Balkan countries, especially Italy and Greece. The effects of the depression will extend to Morocco, Algeria, and Tunisia (with secondary consequences extending to northern Libya) between Monday, September 22, 2025, and Wednesday, September 24, 2025.

The most prominent weather phenomena expected in the Maghreb:

Heavy rain.

Thunderstorms and lightning.

Strong downward winds.

Floods and torrents are possible, especially in the mountains and valleys.

And God knows best.
