WِِASM Regional Center – The center is monitoring the advance of cooler‑than‑usual autumn winds toward the Eastern Mediterranean Basin starting at the end of September, leading to a noticeable drop in temperatures to levels typically seen in November—an unusual development for this time of year.
This occurs as a result of a strong high‑pressure system dominating most of Europe, causing rare autumn heatwaves that raise temperatures in those regions to about 15°C above normal, reaching unusually hot daytime levels for this season.
The slightly cold to cold autumn weather expected at night across the Levant, northern Saudi Arabia, and western Iraq toward the end of the month and the beginning of October will lead to weather fluctuations affecting the Levant, northern Saudi Arabia, and parts of Iraq.
These weather fluctuations are expected to bring scattered rainfall, which may be heavy in some coastal areas of Syria and Lebanon.
These fluctuations will serve as a precursor to intense and widespread rainy systems expected to begin after mid‑October across the region. These heavy rainfall events are forecast to continue intermittently over the coming months, indicating the potential for a record‑breaking rainy season in many areas.
