Saudi Arabia | Seasonal rains will intensify and expand to include these areas on Monday, July 28, 2025.

Arab Weather - Sinan Khalaf - Southwestern and western Saudi Arabia are expected to be widely affected by atmospheric instability starting Monday, July 28, 2025. This is due to the rush of large amounts of tropical humidity and water vapor into the Kingdom's atmosphere, heralding the most widespread thunderstorms since the beginning of this summer.

The expected situation includes large areas such as Jazan, Asir, Al-Baha, and Taif, and to a lesser extent, Makkah Al-Mukarramah and the surrounding mountainous areas, with the possibility of heavy thunderstorms sometimes accompanied by hail showers and active descending winds, which may lead to the formation of torrents and the flow of valleys in some locations.

The displacement of the high pressure system opens the way for tropical moisture.

These developments are attributed to the northward shift of the subtropical high pressure system, which allows the Intertropical Zone Zone (ITCZ) to advance into Saudi Arabia and provides a fertile environment for the formation of widespread cumulonimbus clouds, especially over mountainous regions.
