Arab Weather - Jeddah residents were surprised this morning by an unusual weather scene, as a huge, white cloud appeared, creeping in from the Red Sea towards the mainland. The scene sparked curiosity among many and sparked controversy on social media, with many wondering what the phenomenon was, whether it was a cloud, a dust storm, or something else.
According to specialists at the Arab Weather Regional Center, what was observed is what is scientifically known as "advection sea fog," a weather phenomenon that occurs as a result of warm, humid air moving over a relatively cooler sea surface. This causes water vapor near the surface to condense, creating extremely dense fog that appears from a distance as a white wall creeping toward the shore.
Arab Weather adds that this phenomenon often forms during the early morning hours or after sunset, when sea surface temperatures are relatively low compared to the surrounding air, accompanied by relatively calm winds and high humidity. These conditions are known to be ideal for the formation of creeping fog, particularly in coastal areas.
Arab Weather confirms that the transitional fog does not pose a direct threat to residents, but it may cause a significant reduction in horizontal visibility, which requires caution, especially for vehicle drivers and those navigating sea and air navigation.
While these phenomena are rare along the Red Sea coast, they highlight the diversity and unusual nature of weather events that can occur in unexpected environments, highlighting the importance of continuous monitoring and weather awareness.
