Advanced warning from the National Center for Meteorology
The National Center for Meteorology in Saudi Arabia issued an advanced weather alert today for the Asir region, warning of expected moderate to heavy rainfall. The center explained that this weather system will begin and continue until 8:00 PM, particularly affecting the governorates of Rijal Alma and Muhayil, with the effects extending to neighboring areas.
According to the warning, thunderstorms will be accompanied by a range of severe weather phenomena, most notably high-speed surface winds that may stir up dust and sand, leading to near-zero horizontal visibility. The center also warned of the possibility of hail, flash floods in valleys and ravines, and lightning strikes. The relevant authorities, primarily the Civil Defense, urged citizens and residents to exercise caution, stay away from floodplains and wadis, and adhere to all issued instructions to ensure their safety.
The climatic context of the Asir region
The Asir region is characterized by its towering mountainous terrain within the Sarawat Mountains range, making it frequently susceptible to severe weather fluctuations and the formation of cumulonimbus clouds, particularly during the spring and summer months. The high altitude contributes to the cooling of humid air coming from the Red Sea, leading to condensation and heavy rainfall known locally as seasonal rains or "autumn rains." While these rains are vital for agriculture and groundwater replenishment, they also pose a significant risk of flash floods due to the region's sloping terrain and the rapid accumulation of water in narrow valleys.
Importance and expected effects of the weather conditions
Locally, these warnings directly impact the daily lives of residents, potentially leading to the closure of some mountain roads and disrupting traffic. Flash floods also pose a threat to property and lives if the warnings are ignored. Economically, the Asir region is a vital food basket for the Kingdom, and rainfall is essential for irrigating crops such as coffee and fruits. However, flash floods can damage agricultural lands and infrastructure. As for tourism, Asir is a major domestic tourist destination thanks to its mild summer climate, and these weather conditions may affect visitors' travel plans, necessitating continuous monitoring of weather forecasts.
A comprehensive overview of the Kingdom's weather
The National Center for Meteorology's report wasn't limited to the Asir region; it also indicated a continued chance of thunderstorms in parts of Jazan, Al-Baha, and Makkah, potentially extending to the southern parts of Madinah. Conversely, the report predicted surface winds stirring up dust and sand in parts of Najran, Riyadh, Qassim, Hail, Al-Jawf, and the western parts of the Northern Borders region, while light rain was not ruled out in scattered areas of central Saudi Arabia.
