Lebanon, Syria: Severe weather forecast across Lebanon and parts of northwest Syria until at least February 19
Adverse weather conditions are expected in most parts of Lebanon and the northwestern coastal areas of Syria until at least February 19. The low pressure system is expected to move over the eastern Mediterranean basin in the coming days. Heavy rainfall from the system is expected to be concentrated along coastal areas in Lebanon and Syria: rainfall totals of 8.5-11 cm (3.3-4.3 in) are expected across parts of the affected area until 19 February. It warned of heavy rain at times, thunderstorms accompanied by lightning, and the possibility of hail during the coming days, in addition to a noticeable drop in temperatures and wind speeds of up to 70 kilometers per hour (43 miles per hour). Fog and snow are expected to fall on high areas. Heavy rains may cause flooding in low-lying areas and landslides on unstable slopes. Travel conditions are likely to be dangerous in mountainous areas due to reduced visibility due to falling snow.
Continued heavy rains may lead to flooding in low-lying communities near rivers, creeks and creeks. Urban flooding is also possible in developed areas that have stormwater drainage systems that are easily inundated. Locations downstream from large reservoirs or rivers may be vulnerable to flash flooding after relatively short periods of heavy rainfall. Landslides are possible in hilly or mountainous areas, especially when the soil becomes saturated due to heavy rainfall.
Authorities may issue mandatory evacuation orders for flood-prone communities in the coming days. Interruptions in electricity and communications services are possible when large floods or landslides affect utility networks.
Floodwaters and debris flows may render some bridges, rail or road networks impassable, impacting road travel in and around affected areas. Puddles on road surfaces can create hazardous driving conditions on regional highways. The authorities may temporarily close some low-lying roads submerged in floodwaters.
Severe weather conditions can also lead to flight delays and cancellations at airports in the area. Floods could disrupt regional railway lines. Delays and cancellations of freight and passenger trains are likely in areas with heavy rain and possible track flooding.
Localized business disruptions may occur in low-lying areas; Some businesses may not operate at full capacity due to damage to facilities due to flooding, potential evacuations, and the inability of some employees to reach work sites.
