Authorities in Saudi Arabia have called on the public to be cautious and know of safe areas away from places susceptible to flooding in the event of thunderstorms, the Saudi Press Agency reported on Friday.
The General Directorate of Civil Defense urged people not to swim in vulnerable spots as they are dangerous and swimmers may get into difficulties.
It also instructed citizens to adhere to instructions issued through media outlets and social networking sites.
The authority has warned of the chance of thunderstorms in most regions of the Kingdom, starting on Saturday through until Wednesday.
It said that the Makkah region will be affected by moderate to heavy rains that may lead to torrential downpours, hail, and brisk winds that raise dust. Makkah, Taif, Maysan, Adham, Al-Ardiyat, and the regions of Asir, Jazan, and Al-Baha may be affected.
Moderate rains are expected in the Madinah region and light to moderate in Al-Qunfudhah, Al-Layth, Khulais, Bahrah, Al-Muwayh, Al-Khurmah, Raniyah, Turabah, and the Najran region.
