Heavy rain will dominate the weather today, Tuesday, and continue until next Thursday. Following that, a second, colder low-pressure system will impact Lebanon starting next Friday and will last for many days. Temperatures will drop, marking the coldest period so far this winter, with a possibility of snow falling just below the 1000-meter threshold early next week. The weather report is as follows:
- **General Situation:** A low-pressure system accompanied by cold air masses is currently centered southwest of Turkey, gradually approaching and leading to sometimes heavy rainfall, along with thunderstorms, strong winds, and a drop in temperatures, with snow expected in the highlands until Thursday afternoon when its influence will lessen. It is expected that Lebanon will be affected starting Friday dawn by another low-pressure system, originating from the Black Sea, referred to by the meteorological service as "Daniella." This system will bring colder polar winds, resulting in a noticeable drop in temperatures, leading to snow levels decreasing by the end of the weekend to around 1000 meters by Sunday.
