RIYADH — The National Center for Meteorology (NCM) has forecast thunderstorms to continue across multiple regions of the Kingdom from Friday through Tuesday, with rainfall ranging from light to heavy, intensifying in several areas. According to the NCM, these weather conditions may be accompanied by strong downdraft winds reaching up to 60 km/h, which could stir up dust and reduce visibility; hail; rising wave heights; and flash floods in areas experiencing heavier rainfall. The center also forecast the severity of these storms could increase in certain areas over the weekend. For regions expected to experience moderate to heavy rainfall, certain areas in the Eastern Province — particularly Dammam, Jubail, Ras Tanura, Qatif, and Al-Khobar — will experience the storms, particularly on Saturday and Sunday.
