A deep air depression is affecting the western Mediterranean, and there are fears of torrential floods in several areas of Algeria and Tunisia.

Arab Weather - Meteorologists at the Arab Weather Regional Center are monitoring the impact of a Khamaseen depression on the Maghreb countries, coinciding with the presence of a cold upper trough in the upper atmosphere, on Wednesday and Thursday. This will deepen and intensify the depression, leading to the formation of high-altitude thunderclouds starting Wednesday, May 14, 2025, in northern Algeria and northern Tunisia. Heavy rains and possible hail are expected. The terrain and topography of the land contribute to the lifting of the air, especially in the Atlas Mountains and neighboring areas. Mountain valleys and low-lying areas are vulnerable to sudden torrential floods, in addition to the increased risk of flooding in several areas due to the heavy rainfall expected in some areas.

The depression will continue to affect Thursday, centered between the Italian islands and Tunisia.

On Thursday, May 15, 2025, the low pressure system will move into the Mediterranean Sea and will be centered between the Italian islands and Tunisia. The rotational movement of the winds in the center of the low pressure system will contribute to the direction of large amounts of rain clouds to northern Algeria and northern Tunisia. Consequently, heavy to very heavy rains will continue to fall continuously.

Strong winds and dust storms expected

The weather forecast for the coming days is expected to be accompanied by strong winds and downdrafts during the passage of thunderclouds. These could lead to dust storms and possibly sandstorms at times, reducing visibility and disrupting public life. Please also beware of thunderstorms during the formation of cumulus clouds.

And God knows best.
