5 things that distinguish the deep low-pressure system coming to the Kingdom on Tuesday

Arab Weather - The latest outputs of the weather maps indicate that the Kingdom will be affected by a third-degree low-pressure system starting from Monday night, with its effects increasing at dawn and during the day on Tuesday.

What are the most prominent features of this expected low-pressure system?

The low-pressure system is deep: The incoming low-pressure system is classified as deep due to the significant decrease in atmospheric pressure values at its center compared to the surrounding areas.

It is accompanied by a very cold air mass and a significant drop in temperatures: The low is accompanied by a surge of a very cold air mass, leading to a significant drop in temperatures, especially on Tuesday, when the maximum reaches 5–7 degrees Celsius, and cold to very cold conditions prevail, with active winds and the absence of the sun due to clouds, which increases the feeling of cold significantly.

The air mass is loaded with high humidity despite being very cold: Despite the extreme coldness of the air mass, it is saturated with moisture, which increases the amount of rainfall in several areas. Forecasts indicate that the amount of rainfall may range between 40–90 mm, especially in the north and center of the Kingdom, and may be higher than that locally. It warns of the formation of flash floods and the rise in water levels in valleys and low-lying areas.

Thunderstorms and heavy hail locally: Rain is sometimes accompanied by thunderstorms, and heavy showers of hail are not ruled out in some areas, especially the mountainous highlands, particularly during the peak of the low pressure system's impact.

Strong winds and severe gusts: Wind speeds will increase as the low-pressure system passes through, and will be active with strong gusts, which may exceed 90 km/h, especially in the southern highlands of the Kingdom, in addition to the desert areas and eastern plains, which may lead to dust storms in some areas before the rain falls.

And God knows best.
