11/13/2025 10:50:00 AM
The Meteorological Department at the Directorate General of Civil Aviation expects tomorrow’s weather to be mostly cloudy, with a further drop in temperatures falling below seasonal averages. Dense fog is expected over the mountains, reducing visibility, along with heavy rain at times accompanied by thunderstorms and strong winds reaching up to 60 km/h, causing rough seas. Hail may fall in some areas, with a risk of flash floods on certain roads, especially in the north. Snow is expected at altitudes of around 2,400 meters overnight.
Starting Thursday afternoon, Lebanon and the eastern Mediterranean will be affected by a low-pressure system currently centered over the Black Sea, gradually approaching the region and bringing cold air masses. This will result in unstable and sometimes heavy rainfall, noticeable drops in temperature below seasonal norms, active winds, and thunderstorms. The system is expected to persist until early Sunday before gradually receding. Temperatures are forecast to rise again starting Tuesday.
Average temperatures for November: Beirut: 17–25°C; Tripoli: 14–23°C; Zahle: 8–20°C.

The formation of flash floods is possible overnight.
