The Meteorology Department warns of heavy rains and flash floods expected in Najran and Asir
issued The National Center for Meteorology an advanced weather alert on Friday for the Najran and Asir regions, warning of moderate to heavy rainfall accompanied by a number of weather phenomena that require caution. The center indicated that this rainy weather is expected to continue, God willing, until 10:00 PM this evening.
Climatic background of the southern region
The southwestern regions of the Kingdom, particularly the highlands of Asir and Najran, are characterized by a unique climate, distinct from the rest of the Kingdom's desert regions. Thanks to their towering mountainous terrain, these areas receive above-average seasonal rainfall, especially during the spring and summer months. Thunderstorms develop as a result of the convergence of moist air masses from the Arabian Sea and the Red Sea with the highlands, leading to heavy rainfall that is sometimes accompanied by thunderstorms and hail. This explains the frequent warnings issued during this time of year.
Details of the rainfall situation in the Najran region
In the Najran region, the center predicted moderate to heavy rainfall in some areas. This rainfall will be accompanied by strong surface winds, potentially reducing horizontal visibility to near zero. The warning also cautioned about the possibility of hail and flash floods in valleys and ravines. The affected areas include the city of Najran and the governorates of Habuna, Khubash, Thar, and Yadma.
Warning of heavy rain in the Asir region
In the Asir region, the center raised its alert level, indicating expectations of heavy rainfall. This rainfall will be accompanied by high-speed winds that could lead to near-zero visibility, as well as heavy hail, flash floods, and thunderstorms. The affected areas include the governorates of Al-Harjah, Al-Rabou'ah, Al-Farshah, Sarat Abidah, and Dhahran Al-Janoub.
Importance and expected effects
These seasonal rains have a dual impact on the two regions. On the one hand, they are a vital source for replenishing groundwater reservoirs and supporting the agricultural sector for which the region is renowned, while also contributing to lush vegetation that enhances tourism. On the other hand, the flash floods resulting from the heavy rains pose a significant threat to lives and property, especially in valleys and low-lying areas. Relevant authorities, such as the Civil Defense, are raising their level of preparedness to respond to any emergency and are urging citizens and residents to follow safety guidelines, stay away from floodplains, and exercise caution while driving.
