A rainstorm is forming in the western Mediterranean. Will it affect the Maghreb countries?

<p style=";text-align:left;direction:ltr"><strong>Arab Weather -</strong> Weather experts at the Arab Weather Center said that as a result of the undulation of the polar jet stream, a cold air mass is rushing towards southwestern Europe and a highly effective air depression is formed that affects northern Spain and France in addition to the United Kingdom and the Netherlands. It is accompanied by several air fronts accompanied by dense thunderclouds accompanied by heavy rains and severe thunderstorms. This type of weather condition is usually accompanied, as a result of its combination of winter and autumn characteristics, by strong ascending air currents, which produces exceptional hailstorms accompanied by large hailstones, which damage public property.</p><p style=";text-align:left;direction:ltr"></p><h2 style=";text-align:left;direction:ltr"> <strong>Tropical moisture reaches the center of the depression and causes it to develop into a rainstorm.</strong></h2><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> God willing, tropical moisture will rush towards the Mediterranean Sea in an unusual manner during the coming days, coinciding with the undulation of the polar jet stream and the rush of a cold upper basin towards central and southern Europe via the Tyrrhenian Sea, which is considered part of the Mediterranean Sea, which has been suffering from surface warming in the recent period as a result of marine heat waves.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> <a href="https://www.arabiaweather.com/ar/content/%D8%AD%D8%B1%D9%83%D8%A9-%D8%BA... movement of the atmosphere... tropical moisture reaches the Mediterranean and causes a severe rainstorm</strong></a></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> With the combination of these weather conditions, a rainstorm forms over the European continent, where a deep low pressure system with atmospheric pressure values reaching 997 millibars is created, accompanied by a strong cold air front that crosses many countries and causes a severe rain wave that causes floods and torrents.</p><p style=";text-align:left;direction:ltr"></p><h2 style=";text-align:left;direction:ltr"> <strong>A strong cold front that accompanies a rainstorm (with heavy rain, thunderstorms, and hail)</strong></h2><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> Weather experts at the Arab Weather Center said that the deep air depression will move eastward, and thus the cold air will cross the surface of the Mediterranean Sea, which is suffering from warming, coinciding with the extension of tropical humidity, so that the weather activity will intensify and strongly affect central and southern Europe during the period between Sunday 9/8/2024 and Tuesday 9/10/2024, specifically the Balkan countries, especially Italy and Greece. A severe cold air front will form, accompanied by high-altitude thunderclouds, accompanied by heavy rains, thunderstorms and severe and successive hail, which increases the risks of torrents and floods in many areas.</p><p style=";text-align:left;direction:ltr"></p><h2 style=";text-align:left;direction:ltr"> <strong>The effects of the rainstorm on a complex state of instability include 4 Arab countries</strong></h2><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> In this context, and as a result of the warming of the Mediterranean Sea and the passage of cold air in the upper layers of the atmosphere, and coinciding with the rush of tropical moisture, a state of complex characteristics of atmospheric instability is formed over 4 Arab countries (Morocco, Algeria, Tunisia and western Libya), which will intensify on Sunday and Monday and continue until Tuesday 9/10/2024. Thus, thunderclouds are formed that grow to towering levels in the atmosphere.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> It is accompanied by severe weather phenomena such as (heavy rain, thunderstorms and lightning, strong hailstorms with large hailstones, and strong downward winds). The terrain and topography of the land contribute to the process of lifting the air, especially the Atlas Mountains and neighboring areas. Mountain valleys and low-lying areas are susceptible to the sudden formation of torrential floods, in addition to the high risk of flooding in several areas due to the large amounts of rain expected in some areas.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> <strong>See also:</strong></p><p style=";text-align:left;direction:ltr"> <a href="https://www.arabiaweather.com/ar/%D8%A7%D9%84%D8%B7%D9%82%D8%B3-%D9%84%D... day weather in Algiers, Algeria</strong></a></p><p style=";text-align:left;direction:ltr"> <a href="https://www.arabiaweather.com/ar/%D8%A7%D9%84%D8%B7%D9%82%D8%B3-%D9%84%D...
