WASM– A rainfall event that will last for a very long period in the form of successive heavy rainfall waves. It begins deepening tomorrow, Tuesday, and continues through the first half of November. Heavy waves are expected Tuesday and Wednesday, followed by additional waves in the middle and end of next week, and even stronger, more widespread waves during the second week of November.
- A highly humid equatorial wave has begun deepening and is centered over northwestern Saudi Arabia, pushing toward the Levant and Iraq on Tuesday and Wednesday, coinciding with a deep low‑pressure system north of Egypt, resulting in severe and widespread weather disturbances.
- A second, deeper and more humid equatorial wave is being monitored for the second week of November, expected to bring additional heavy rainfall to the region.
- Record‑breaking rainfall amounts are expected in parts of Iraq and Syria during the coming period due to heavy rainfall and successive waves.
- The climate model of the WASM Regional Center continues to detect the onset of heavy rainfall events with exceptional accuracy, outperforming all local and global sources.
The detailed seasonal weather bulletin for the Arab region for 2026–2027 has been issued.
