Saudi Arabia | A tropical humidity wave brings thunderstorms to six regions. Details.

Arab Weather - Sinan Khalaf - The latest analyses issued by the Arab Weather Regional Center indicate increasing indications that the southwestern and western regions of Saudi Arabia will be affected by unstable weather conditions starting next Monday, July 28, 2025. This is due to the rush of large amounts of tropical humidity and water vapor towards the region, which increases the chances of thunderstorms and widespread rainfall , for the first time this summer.

Expected weather changes allow tropical moisture to flow.

These expected weather changes are due to the northward shift of the subtropical high pressure system, which opens the way for the Intertropical Zone Zone (ITCZ) to advance towards Saudi Arabia, thus allowing tropical moisture to penetrate the southwestern and western sectors, creating a suitable environment for the development of cumulonimbus clouds .

From Jazan to Makkah, Madinah and Taif: Possible thunderstorms

Jazan , Asir , Al Bahah , Taif and other nearby mountainous regions are expected to be affected by this condition, with thunderstorms expected, sometimes heavy, accompanied by hail and strong downward winds , increasing the risk of flash floods in valleys and low-lying areas.
