Dust blankets the western part of the Kingdom for the third consecutive day. What are the causes?

Arab Weather - The latest satellite images show that a large dust storm continues to affect the eastern slopes of western and southwestern Saudi Arabia for the third consecutive day.

This dust storm formed in the southern skies of Iraq more than 72 hours ago and gradually moved toward the Kingdom, passing through Hafar Al-Batin. It then swept across large areas of central Saudi Arabia, including the capital, Riyadh, before settling over the western parts.

Dust still hanging in the air after three days

What's striking about this case is that the dust remains suspended in the upper atmosphere without dissipating, even three days after its formation. This is attributed to the weakness of the upper air currents, which play a key role in dispersing dust particles and dispersing them throughout the atmosphere.

Dry soil contributed to the rising dust.

Arab Weather experts reported that the weak rainy season and dry soil in Iraq played a significant role in the formation of the dust storm. The soil became fragile and easily crumbled, allowing winds to carry it long distances, crossing hundreds of kilometers from the east of the Kingdom to its south and then west. This caused a significant decrease in visibility and deterioration in air quality, especially in mountainous and populated areas.

Continuous warnings from the competent authorities

Relevant authorities, led by the National Center of Meteorology and Civil Defense, continue to issue warnings to residents of affected areas, urging them to avoid direct exposure to dust, especially the elderly and those with respiratory conditions, and to limit outdoor activities until weather conditions improve.
