Lebanon: Adverse weather forecast across much of the country through Dec. 31

Adverse weather conditions are forecast across much of Lebanon through Dec. 31. The Lebanon Meteorological Service has warned that a low-pressure system moving into the region from the Mediterranean will bring heavy rain, snow, thunderstorms, and strong winds. Snowfall and fog are expected in elevated parts of the country.

Due to the region's arid nature and poor stormwater management in some urban areas, even minor rainfall accumulations could quickly result in episodes of flash flooding. Flooding is possible in low-lying areas, streams, and wadis (dry riverbeds). Urban flooding is also possible in developed areas with easily overwhelmed or a lack of stormwater drainage systems. Moderate winds and dust storms may precede significant rainfall, though some areas - particularly desert areas - may experience high dust levels without rain. Landslides are possible in hilly or mountainous areas, especially where heavy rain has saturated the soil.

Floodwaters and debris flows may render bridges or roadways impassable, impacting overland travel in and around affected areas. Ponding on road surfaces could cause hazardous driving conditions on regional highways. Flooding could block regional rail lines; freight and passenger train delays and cancellations are possible in areas with heavy rainfall and potential track inundation. Severe weather could also trigger flight delays and cancellations at regional airports.

Localized business disruptions may occur in low-lying areas; some businesses might not operate at full capacity because of flood damage to facilities, possible evacuations, and employees' inability to reach work sites. Electricity and telecommunications service disruptions are possible where significant flooding, strong winds, or landslides impact utility networks.
