WASM – The rainfall event continues in the form of successive heavy rainfall waves and will persist through the first half of November. Cold, winter‑like low‑pressure systems are expected in the middle and end of next week, followed by even stronger and more widespread waves during the second week of November.
- Cold, winter‑like, and heavily rainy low‑pressure systems will affect the Levant, Iraq, northern Saudi Arabia, and Kuwait during the second half of next week due to the rare early approach of polar winds toward the eastern Mediterranean.
- 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, especially the Arabian Peninsula and Gulf countries.
- 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.
