WASM | A Strong Cold Wave Affects the Levant, Northern Saudi Arabia, and Iraq as Weather Conditions Stabilize, While the Highly Active Low-Pressure System Shifts Toward Riyadh, Al-Qassim, Qatar, and Bahrain
- The highly active low-pressure system triggered severe flooding and flash floods across several areas of Jordan, Palestine, Syria, Lebanon, and Iraq, and is expected to continue impacting large parts of Saudi Arabia.
- A moisture-rich tropical wave will coincide with the early-season weather system, bringing additional heavy rainfall across extensive areas of Saudi Arabia and the Gulf region, including Riyadh, Al-Qassim, and the Eastern Province for the first time this season. Significant rainfall totals are expected.
- Another widespread and heavy regional rainfall event associated with strong tropical activity is being monitored for the period after mid-November. The event is expected to focus primarily on the Levant and western Saudi Arabia before gradually expanding into broader areas. Further details will be announced soon.
The November 2026 Monthly Outlook has been issued.
Details of the Low-Pressure System
A strong and unusually early cold wave is affecting the region, causing temperatures to fall below 5°C in several locations.
Meanwhile, the influence of the low-pressure system is shifting toward central and eastern Saudi Arabia, as well as Qatar and Bahrain, with the primary focus on Riyadh and Al-Qassim during the coming days through the end of the week. The system is expected to bring significant rainfall accumulations and an elevated risk of flash flooding.
Saudi Arabia, the Gulf Region, and the Arabian Peninsula
Temperatures are expected to decline substantially across northern and northwestern Saudi Arabia, with winter-like conditions arriving unusually early following the retreat of the low-pressure system from the northern regions.
Heavy rainfall activity is expected to intensify across central and eastern Saudi Arabia, focusing on Riyadh, Al-Qassim, and the Eastern Province, particularly on Tuesday and Wednesday, before redeveloping toward the end of the week.
Successive severe rainfall events are expected to continue across the region in the coming weeks. Another powerful rainfall event is being monitored for later in the month, focusing mainly on western Saudi Arabia, with further details expected soon.
The Levant
A strong and seasonally unusual cold wave is affecting the region, with temperatures falling below 5°C across mountainous and lowland areas, and potentially lower than that over higher elevations.
