The National Center for Meteorology (NCM) has issued red alerts as severe thunderstorms, hail, and flash floods are expected to impact several regions across Saudi Arabia through Friday. The NCM predicts that moderate to heavy rainfall and thunderstorms will persist across sections of Jazan, Asir, Al-Baha, and Makkah until September 4, with precipitation forecast to intensify on Wednesday in portions of Jazan and Asir.

Simultaneously, the Civil Defense has mapped the Asir region under a red alert, with similar rainfall projected for Abha, Khamis Mushait, Ahad Rufaidah, Sarat Ubaidah, Al-Harjah, Dhahran Al-Janub, Al-Namas, Al-Farshah, Tanomah, Rijal Almaa, Bariq, Mahayil Asir, Al-Majardah, and Balqarn.

Residents are advised to monitor weather updates via the NCM's Early Warning page, the Anwaa app, and official social media platforms.
