The National Center for Meteorology in Saudi Arabia issued its daily weather report, indicating continued weather fluctuations across various regions of the Kingdom. The report stated that there remains a chance of scattered rainfall, which may be thundery at times, in parts of Jazan, Asir, Al-Baha, and the highlands of Makkah, as well as the northern parts of the Kingdom. The Center also warned of the possibility of fog formation during the night and early morning hours in parts of the Eastern Province, which could reduce horizontal visibility.
Climatic context and topographical influence
These forecasts come within the context of the great climatic diversity that characterizes the Kingdom of Saudi Arabia, given its vast area and varied topography. While the southwestern highlands (Asir and Al-Baha) enjoy a more temperate climate and relatively higher chances of rainfall due to their elevation, the weather differs in the eastern coastal regions, which are influenced by the waters of the Arabian Gulf. This increases the likelihood of fog formation, along with humidity and lower nighttime temperatures. These weather alerts play a vital role in the daily planning of citizens and residents, particularly in the agriculture, transportation, and maritime sectors.
Importance and expected effects
These weather phenomena have varying impacts on daily life and economic sectors. Rainfall in the southwestern regions is a primary source for replenishing wells and dams and supporting the agriculture for which these areas are renowned. However, it can also pose a risk if it is heavy, increasing the likelihood of flash floods in valleys. Fog formation in the eastern region, a major industrial and oil hub with vital ports and airports, necessitates heightened caution among drivers on highways and may affect air and sea traffic. Therefore, relevant authorities, such as Civil Defense and Highway Patrol, emphasize the importance of heeding warnings issued by the National Center for Meteorology and adhering to safety instructions.
