Saudi Arabia | Seasonal cases continue... Monitoring the possibility of a new rainy and toxic case forming at the end of the week

Arab Weather - Specialists at the "Arab Weather Regional Center" are monitoring what the latest outputs of numerical models for forecasting and tracking the movement of weather systems and air masses indicate regarding the possibility of large parts of the Kingdom being affected by a new rainy and toxic condition, which is the second of its kind this season, resulting from the concentration of a low-pressure system in the eastern basin of the Mediterranean Sea, accompanied by a cold air mass, in conjunction with an extension of the Red Sea low, and an influx of tropical moisture from the south, which causes the emergence of a widespread state of atmospheric instability, the effects of which will continue for several days.

Second of its kind this season

It includes important cities, regions and large parts of the Kingdom starting from Wednesday.

Experts at the Arab Weather Regional Center believe that weather conditions are clearly supporting the formation of the second seasonal event of its kind this season starting from Wednesday, as cumulonimbus clouds form on a wide scale, covering all western parts of the Kingdom, including Jazan, Asir, Al-Baha, Taif, Makkah Al-Mukarramah, reaching Madinah, Hail, Al-Qassim, Hafar Al-Batin region, and the northern parts of the Riyadh region administratively, accompanied by a number of weather phenomena.

Important weather phenomena expected

Thunderstorms and hail showers may be heavy and accumulated at times.

The weather forecasting staff at "Arab Weather" indicated that all the mentioned areas will be exposed to showers of medium and sometimes heavy rain, which may cause valleys and torrents to flow, and it is also possible that showers of hail will fall, which may be dense and accumulated at times, especially in different parts of the Hail and Qassim regions.

Down winds accompany thunderstorms

Possible dust waves accompanied by a decrease in horizontal visibility

It is also expected that some of the mentioned areas will witness descending winds before and during the passage of cumulonimbus clouds, which will cause dust and dirt to be stirred up and possibly local dust storms, especially in open areas before the rain falls, which requires the installation of tents and volatile objects, and God knows best.
